This is so helpful! Thank you.
Gadolinium ruined my health via immediately triggering Gadolinium Deposition Disease, it is not "safe".
Why do some Women who get their annual Mammogram screening still end up with large size cancer tumors? These Cancers finally get discovered only after years of growing inside their bodies. Obviously, Mammograms are not the Gold Standard for testing all Women. There is a new FDA approved Dedicated Breast CT Scanner. The Koning Vera produces true 360 -degree views of your breasts. The advantages include that there is no compression pain free, quick, and most importantly more accurate even when a Women has dense breast tissues. The benefits include that more Women will also get their annual breast cancer screening. Right now, there are an estimated 25 to 35 % or more who for various reasons refuse to get their annual screening scan. These reasons include pain due to compression, trauma associated with false positives or negatives. Google Koning Health CT
Thank you Dan!
Agreed wtf is this guy saying speak English
cheaper for people to pay cash. Insurance is a ripoff.
Great information.Thank you so much.
MRI can be done for blunt truma in kidney (one year after accident) instead of CECT KUB for a 25 year old STABLE PATIENT?
right thyrood nodle TI-RADS:4, 2.2 cm right posterior mid lower pole. needs FNA, New onset hyothyroidism
So in plain English. Does this mean cancer or no?
Good heavens. This is so hard to listen to. As usual, the US PTF is behind the curve. There’s no such thing as overdiagnosis. There is only over or under treatment. What is a false positive? Many organizations consider a false positive to be a callback after a screening examination. That’s not a false positive. As far as overdiagnosis is concerned, the role of the radiologist is to find cancer. 20% of DCIS Will go on to become invasive breast cancer. No imaging modality or other modality at this point can predict which of those patients will go on to develop invasive cancer. Raise your hand if you want to be one of the 20%. That is not a reason to not to screen. everything they are doing seems to be based on old literature and meta-analysis. No mention of Tomosynthesis. The state of the art has changed. The issues regarding breast density are real and are not really considered by the government. As far as outcome is concerned, the USPTFS Falls in the trap of using outcome with regard to imaging technology in the same way, as they would assessing a drug trial. Saying that there was no difference in “stage of diagnosis“ Harkins back to To certain investigators from the oncology community who have published in the past and are definitely anti-mammography and have said that there is no big deal in detecting stage two breast cancer. For the radiologist, the only outcome with regard to looking at any imaging modality is whether or not the modality is effective in detecting cancer. it is up to others to determine the appropriate treatment on the cancers we detect so as to prevent unnecessary mastectomy. Our goal is to detect as early as possible hopefully the US PTF recommendations will catch up to the contemporaneous research which has been done and is being done showing that yearly mammography beginning at age 40 is beneficial. We have been arguing about this for years.
How do I find a physician to treat you for a possible CSF. I had a known CSF in 2010 and had a blood patch and another CSF in 2018 immediately after having my second lumbar spine surgery that warranted a second emergency surgery the next day to close a large leak. Since have been experiencing all the classic symptoms that a CSF can cause since 2017-2018 that I believe started sometime after my cervical spine surgery or the lumbar surgery. I have had three lumbar spine surgeries and the one cervical and honestly since 2018 I began having the headaches first than the other symptoms started causing doctors in all other specialties diagnosing each symptom separately but no one expects a CSF I don’t know how to explain to my doctors to where I am taken seriously. I even have spinal fluid sitting in my lumbar region since 2018 but that hasn’t warranted any concerns from my Texas doctor.
Op😊❤
Great teaching video. thankyou
💊🤫💊🤫💊🤫💊🤫
with all the info out there about dense breast tissues why do I have to be educating my Dr about it?!
is dr. Callen notified of comments on this presentation? Seems like pretty solid work, and i wonder if he can comment on approaches at Dr. Beck's group at university of Freiburg? Just wondering, as i appear to have a leak that is refractory to imaging, but results in symptoms appearing within minutes to an hour, with the only indicator, so far, tiny drops of clear fluid from one nostril under valsalva-like conditions...started immediately after an examination that hyperextended the neck...
Could you please make a video for how to quantify visceral and subcutaneous fat quantification from the abdominal MRI images?
What if 55 year old? Not a candidate for test?
56 gonna have the test next week because of a 4 cm tumor on my right adrenal gland

Thank you so much pro
EDIT: At the end of this very long posting, I have a brief 1 year post-op update. It's May 2023 and I'm currently undergoing this surgery to both legs, due to Varus Deformity causing the medial compartments of both knees to be "worn out" and the margins indicating at, or nearly, bone-on-bone. I'm a 59 year old man, and an extremely fit long distance, endurance, trail runner(I run Rim2Rim at the Grand Canyon), and pretty hard core mountain biker. I'm extremely healthy. I still have the same body I had when racing Cross-Country in middle school, high school, and college. I still doing everything I did back then, and just as hard. No prescription meds, no blue pill, etc. I had my right leg HTO done Jan. 23, 2023, and the deformity was such that the open wedge was 18mm. This made my right leg 1 inch (25cm) longer. I had bone from the Iliac Crest of my right pelvis placed in the opening, as a bone graft. A Tomofix Plate was used to secure the site (which appears to be a much better component, as compared to what's shown in your video). I was driving at 3 weeks, and a radiograph at 4 weeks showed the 18mm opening was completely filled with bone. When my Ortho saw the x-rays, he moved my 2nd surgery date up, to be at 8wks post-op, instead of 16 weeks. I started walking without crutches at 4 weeks, first with just 3 steps on day 1 of the 4th week, and by the end of the week, I could walk carefully, back and forth in my house, about 30'. At the beginning of week 5, I walked about 250' on the sidewalk in front of my home, and by the middle of the week, I put the crutches away for good, and even mowed my small yard. On day 1 of week 6, I returned to mountain bike riding, on the same technical, rocky, climbing trails I was riding before surgery. I road 4 times that week, but very carefully and used my unrepaired leg as the majority of the power source. On day 1 of week 7, I began riding the mountain bike aggressively again, did another 4 rides, and the final ride was a 20mi, double 1,000' peak climb. Surgery #2 was 4 days later, on Mar 23rd. On the 2nd surgery, I was driving in the 2nd week, and by the end of the week, starting to take a few steps. In week 3, I was walking without crutches, and just before the start of week 4, x-rays showed that the open wedge was not only completely healed, it was completely solidified and was barely recognizable in the images. I went right back to normal function (other than a stiff knee, sore distal knee area, and sore hip/hip flexor area just as my right leg had been). I started to ride the mountain bike again, but only 2 times a week. However, I didn't hold back on how I rode... I was back to flogging it, just as I had, prior to ever having surgery. I went back to things like mowing the lawn, weeding the garden, etc. The more I rode the mountain bike, the better my knee and hip felt, which is how the recovery had gone with the first leg. It is now week 6, and after 2 weeks of mountain bike riding, and doing yard projects, and other normal things, including working part time as a mechanic, I am literally back to 100% functional. I've done my own PT, using a Keiser M3 spin bike, and that's it. In the middle of the recovery of the 2nd leg, I celebrated 90 days from the start of this project, with a 20mi, double peak mountain bike ride, followed by a walking lap around the local college track, and an attempt to return to running. I was only able to "trot" about 100m, but was happy with the overall progress of the recovery. I'd basically done in 90 days, what was originally spec'd to take 8 months or more. I have been posting updated to my journey to YT in hopes that it helps others to see what HTO is like, and those can be seen starting here: studio.th-cam.com/users/videoSDhvUzSehdU/edit UPDATE: Jan 2024 I returned to "real" trail running, in June of 2023, by July I was able to run a trail half marathon, every other day, for a week. Mid-August, I celebrated my 60th birthday, by running my 11th Rim2Rim in 9yrs, and I ran it as a marathon distance. Video here: th-cam.com/video/cYwz8235_58/w-d-xo.html I continued training, both on the mountain bike, and trail running, and raced a trail half marathon with 2,600' of vert, on Sept. 4th, placing 3rd overall. Video here: th-cam.com/video/XJJAyAcK2mE/w-d-xo.html I returned to the Grand Canyon on Oct. 7th and ran another Rim2Rim as a marathon distance, but this time as a speed run. In early Nov. 2023, I raced another trail half marathon, this time with 2,400' of vert, and I won the race. Video here: th-cam.com/video/grAaMt-gA1M/w-d-xo.html On Dec. 11, 2023, I had the Tomofix plates removed, and on Jan. 1, 2024, I started trail running again. Plate removal surgery: th-cam.com/video/cttr2U1e16k/w-d-xo.html First run of 2024: th-cam.com/video/f5sVL7rdSXE/w-d-xo.html

@@danielroman6280 its been good so far i guess, i was on a very low fat diet but now i can nearly have the normal amount of fat. i had a pleural effusion before the meds kicked in but now i havent had one for half a year
Please help me please..... when I sit upright I feel so much pressure building in my head and when I stand it doesn't get any better when I lie down, then the pressure goes away and I feel relief
Did you try to look into SIH as a cause?
@@konosmgr it has something to do with a Venus fistula, most likely in the thoracic spine
@@ahilleastsavalos5573 What imaging did you do to come to that conclusion. I'm greek by the way.
@@konosmgr My doctor ordered 2 CT angiogram scans at different times, while I was working with another neurologist to remove a dural arteriovenous fistula In the back of my head. So then I told him my remaining symptoms after the first surgery and saw on the second scan that both of the internal jugular veins were severely narrowed and said it's a definite tell tale sign of a CSF leak in the spine, caused by a Venous fistula. So now I'll be getting a CT myelogram to pin point where the venous fistula is
@@ahilleastsavalos5573 Interesting, the assumption that it's a venous fistula specifically based from jugular stenosis is the first I'm hearing of this kind of this kind of correlation. Although thought rare they make up about 1/5th of cases from the data I saw between 2018 and now. Apparently you didn't have a spine MRI beforehand but did you do a brain MRI and was it inconclusive? By the way what country do you currently reside in? I'm in a similar boat right now and suspect SIH I'm told to proceed with brain angiography but I'm wondering if I should push for a CT myelography first since nearly all CSF leaks are caused in the spine.

Hello, I'm a Korean woman. The cerebrospinal fluid leaked into the bundle, so it could not be completely cured even after a year. There is a leak in the front of cervical vertebrae 6~ thoracic vertebrae 2, but the blood patch is not successful. It's so painful and sad. Is there any other treatment?
How are you now
how did u get diagnosed with cervical and thoracic leak? do they do a full spinal MRI with contrast?
Maybe try ketogenic diet. Its may help with spine injuries
Very good paper! I am writing my bachelors degree about FFS and this helped a lot! Thank you ❤️
Hi Andrew! Great info . I’m trying to send you an email from Australia and I’m using the email address you have at the end of the video. It’s not going through? Can you tell me if this is still correct?
The clarity of this presentation is phenomenal! Thank-you
Thank you Karen, I hope you found it helpful.
They need to change the description from 'headache' to head PAIN. There's nothing headachey about it, it's horrific head PAIN. Using the word headache undermines and minimises the suffering SIH causes. The pain SIH causes is like nothing else on earth and sufferers have even chosen suicide just to get relief as the pain is so relentless. The pain needs to be controlled with the strongest medication until the leak is fixed. Its NOT a 'headache'! Its debilitating and relentless head PAIN (head pain being just one of the dozens of symptoms it causes) I'm glad there's more dialogue about this condition as more awareness is badly needed. Great video!
I called my headaches “positional head pressure” for 6 years before I learned the term, “orthostatic headache.”
You are absolutely right that many patients don't experience what many would describe as "headache", and many of my patients describe symptoms different than headache entirely. There is much to learn about this condition. Thank you for your comment.
Thank you for this information. I'm over 60, female, and have a 6mm gallbladder polyp that was incidentally found on an MRI a year ago. On my one year follow-up Ultrasound, the polyp has increased to 9mm. I have no symptoms. Should I have my gallbladder removed as soon as possible?
How are you now? Was the gallbladder removed? I hope you're OK. I'm 64 and had the same. Incidentally found a 5mm polyp on my gallbladder last week. They want to do another ultrasound a year from now and I hope it doesn't grow.
Way to go Justin!
It was my greatest opportunity using Dr.Uromi herbal medicine on TH-cam for herpes which gave me alot of concern , today I have been cured of herpes virus since November 25 , 2020 , I appreciate #Druromi for his help ..
Wonderful talk
Quick question Dr..if one has a few polyps, with the largest .7cm, has completely removed sugar and carbohydrates from the diet. Also implemented a recent 4 days fast , only eating once a day after that. Also only eating grass fed and organic foods. Would monitoring be suffice for treatment , avoiding removal of the gallbladder initially?
I have just been diagnosed with 1 polyp 0.7cm my diet is similar low carb and omad, I don’t have any gallbladder blockage or stones so even after watching this twice are they saying yearly is too much because polyps can shrink and grow naturally or are they saying yearly scans should be done instead of every 3 months and the increase in growth marker is too high if checking for cancer, I’m confused I’m going to look for the paper very timely
@@pathancock3533 thank you for the response , I’ve also been incorporating grape seed extract , Resveratrol, vitamin d and Quercetin. Hopefully I can keep this organ

Interesting, thank you for sharing this information, it is funny for someone lived the era of Xeromammography and classical mammography and passed through many modern technologies for breast examination. Where we were? where we are? and where we will be? We had a 96% diagnostic accuracy for combined mammography and clinical evaluation (no mention of missing tiny lesions i.e early pick up, since there was no mass survey programs in most countries). Where we are now?
Very interesting!
