Haha, you're definitely right. Sometimes they have a point too. If I'm tired or lose enthusiasm my voice probably drops a register and I mumble. I try to do better these days, so hopefully it's better on the newer videos
Thank you very much. I wondered in a case of, say, wanting to see detail of a compressed IJV and also possible ICA dissection eg. to do with Eagle Syndrome, whether MRA and MRV can be combined or something?
Yes, they can be done at the same time but you need to know in advance that you are evaluating both. So your doctor would need to order both the MRA and MRV because their timing is slightly different.
Hi, thanks for the very informative video. I'm an amateur learner - does an MRA scan looks at veins, ie. IJV, as well as the carotid & other arteries? Also, does a 'head' MRA usually include the neck? in other words, how far down does the 'head' scan include? I'm wondering if below the hyoid? I can't find a clear answer searching. Thank you.
MRA usually does NOT include the veins. This is on purpose, as seeing the veins obscures findings we might see in the arteries. There are some exceptions to this, like dynamic angiography, where you have images in more than one phases. To see veins, we usually use specific venography, or venous targeted, images. Brain MRA does not go below the skull inlet. So no it usually stops a few centimeters below the carotid canal and you would not see the neck. There are dedicated MR exams of the neck, or MRA of the neck for that purpose.
Excellent course. Would really love to learn additional ones such as basal crane foramens, brachial plexus, head and neck spaces. Thank you so much. Best of luck!
Hello, my doctor sent me to get an MRA, but after reading some scientific literature, I suspect some sort of Cerebral or Jugular vein narrowing/thrombosis. I cant seem to find a definitive answer, but is it true that an MRA is not sufficient to diagnose this illness because it does not image the veins? 70544 is the given code. No one I ask seems to be able to help me on this.
That's correct. MRAs image arteries. You won't see the veins on an MRA. There are MR venograms, or MRVs, for this purpose. However, symptoms from dural venous or jugular narrowing are quite uncommon except in a few specific diseases. Venous narrowing or obstruction has been blamed for many diseases over the years but few have been proven true.
@@LearnNeuroradiologyI very much appreciate your response. I seem to have a chronic ear infection so that's why I suspect it could have spread to the veins, I get checked out next week so I guess I'll find out then. I will try and see if maybe the ENT could give me some more insight, as I know CVST is a rare complication of untreated ear infections. If I have any interesting updates I'll let you know!
Hi! Thanks for the question. We are a mostly Siemens site. It is beyond the scope of our discussion here what all the parameters for each sequence are, as it would be a lot of technical details that are usually provided by the scanner manufacturer. Plus, those parameters are available elsewhere. Some useful places to start are: radiopaedia.org/articles/mri-sequence-parameters?lang=us mriquestions.com/mra-parameters.html mrimaster.com/PLAN%20MRV%20BRAIN.html
Yes. Many times you can see areas of narrowing or occlusion before a stroke. In those cases, the brain is still getting enough blood flow, either through the narrowing or from collaterals, that the brain doesn't have ischemia.
@@LearnNeuroradiology Hi, thanks for this. I had an MRI scan and I'm definitely no expert, but the images did not show much clarity for my vessels (the report came back fine). I suspect I have a blood clot and am getting and MRA/MRV. Is it possible that a normal contrast MRI of brain could miss blood clots which only MRA/MRV could pick up? Or is there some overlap, as in, maybe depending on the clot. I am getting my MRA/MRV scan done and was curious
An MRA is much more geared towards evaluating areas of narrowing or clot, and most MRIs without an MRI would not necessarily see a clot. I think you probably have to talk to your doctor about what symptoms make you concerned you have a clot so that it can be clear that you're getting the right kind of scan. If they need to, they can talk to the radiologist and ask what is the best way to evaluate a specific problem.
There is actually a variation of MR angiography designed to look at veins called MR venography (or MRV). Conventional MRA does not assess the veins well.
Hi Doctor, thank you for this video. I have pulsatile tinnitus in one of my ears and I've been recommended for CT Angiogram. The CT scan requires injection and I don't want it as I had reaction to it in the past. Is an MRI a good option to investigate the cause of this. Thank you for your help. Kind Regards
Most of the time you can get similar information from an MRA without contrast. You should talk to your doctor about whether that's a good option for you. Additionally, depending on the severity of your reaction, you can often take some steroids and antihistamine the day before the exam and limit your risk of another reaction, so that's another option. Good luck.
Hi Doctor, Thank you for your response, really appreciate it. The Doctor gave me a referral for MRI non-contrast. The MRI result came back normal. This made me happy despite the symptom in my ear. The symptom is only present when I lay down but not in all positions. The Doctor stated that he recommends a CT scan of the temporal bones. This would require an injection and also exposure to radiation. Does the MRI show the temporal bones? I would rather do another MRI with injection instead of a CT scan. I have a referral to a specialist too and will book an appointment soon. Thank you very much Doctor and sorry for the long response. Kind Regards
@@DT-mw3ge The CT will show the bones better, and the amount of radiation is quite low. It is appropriate given your symptoms. Similarly, CT contrast is very low risk and worth it given the symptoms that you are having.
Hi Doctor, I hope you are well. Thank you for encouraging me to do the CT scan. After I had my MRI head that came back normal I wanted to give some time to see if the symptoms would disappear before I went for ct and put myself under radiation. To my surprise it only took few minutes and I expected to be under the machine longer than that. I finally went and had CT Temporal Bones. The report came back normal stating things like no mass lesion, no vascular dehiscence, no Sigmund sinus dehiscence and no destructive skull base mass etc. This is very good except that I still hear this pulse sound when I lay down, more noticeable on the left side than the right side. As I have done so many tests including MRI Head, CT Temporal Bones, ECG, Carotid arteries ultrasound, Chest MRI, Hearing test and ear cleaning I am left with few options. Apart from this pulse sound I also have some chest discomfort but the scan never shows anything. I had blood tests few months ago and it showed everything fine but iron level 8/10 but ferritin normal. My last two options are the blood test which I've done this morning looking into more details like full blood count, inflammation etc and the second is to have chest blood vessels angiogram. I never had chest angiogram, only MRI Chest that never says anything about my blood vessels. Because I have chest discomfort maybe my ear is picking on the internal sound. I dont know if something like that is possible but I know that I've done so many tests with no explanation and still have chest discomfort and still hear this pulse. I am 34, don't take any medications and no vitamins right now. I am able to exercise and do so 3-4 times a week when my busy life allows me to do so. I eat well too. I am doing all I can yet the pulse is still there when I lay down but chest discomfort I feel through the day too. Mind you, the pulse isn't very loud but can hear it. I am still able to fall asleep in certain positions and on the right side as my right ear is better and it doesn't wake me up through the night. Doctor, if you have any recommendations on any other test I could do please let me know. Thank you so much. Kind Regards.
Yes, I have seen MRAs on patients with meningitis and encephalitis. Most of the time they are normal. However, sometimes meningitis precipitates a reactive vasculitis (because the infection is in the subarachnoid space around the vessels). In those cases, the patient can have infarcts and abnormal MRA with areas of nodular vessel narrowing (just like other vasculitis). It's not mandatory, but I would say nearly every MRA of the head or neck in the US will have them. Most of the time they are generated by the technologists. I think the reimbursement may be slightly higher if there are 3D reformats.
why dont pcomm arteries show on mra? if thinner slices are done will it get visualised better? need to diagnose a patient for 3rd nerve palsy with pupil involvement and aberrant regeneration so there is suspicion of pcomm aneurysm.
The posterior communicating arteries are very small, so it is a balance. Time of flight MRA depends on flow to generate signal, and small arteries quantitatively don't have that much flow. Plus they are smaller than the resolution of the method, so they can be hard to see. You can decrease the voxel size (thinner slices, smaller voxels) but then you have less signal in each voxel, so you may have to image longer. MRA at 7 Tesla is substantially better than 3 Tesla, and can see much smaller vessels for this reason. However, it probably doesn't matter. Any aneurysm big enough to cause a 3rd nerve palsy is probably going to be seen on an MRA (more than 95% of the time). If you still had concerns you would have to get a CTA or a catheter angiogram.
An MRA is designed to look at arteries and an MRV is designed to look at veins. You can achieve this by changing the direction of flow you are looking for, or by changing the contrast timing.
Thank you so much for the great information. I just had my covid19 vaccination, would it affect the readings of MRI or MRA of the brain? If yes , when it is safe to do the scan..Thank you
Congratulations on getting a covid vaccination! Thanks for committing to keeping yourself and those around you safe from the virus. Although it's not studied, the coronavirus vaccine will not affect your brain in any way on an MRI or MRA. You can get your scan right away, although you might feel tired a day or two after your shot, so you might delay it by a day or two just so you can be more comfortable.

Thanks for your informative video! Apologies if I'm asking something out of your expertise, but not too long ago I've suffered a ruptured brain aneurysm - underwent coiling procedure and was lucky to survive without permanent issues. In a month or so, I will have to get the one-year follow-up exam, and one of my neurosurgeons insists I get a DSA, while the other says it's unnecessary and I should get an MRA instead (already had one at 6 months). Is the MRA is reliable as a DSA in your opinion? I will appreciate any information, thank you in advance :)
It is an individual decision, but the vascular neurosurgeons at our institution use MRA extensively for follow-up evaluation of treated aneurysms. They have found that it is just as good as an angiogram in most cases, and can avoid a lot of patients having a procedure. In these cases, we do special MRAs of the brain that do have a contrast injection to see any aneurysm filling better. (you can read more about it here: www.ncbi.nlm.nih.gov/pubmed/24994828). Sometimes, if we don't see it well we still recommend angiograms. Some neurosurgeons may not be familiar with this technique, or it might not be available at your institution. Catheter angiograms (DSA) are the classic gold standard and they may prefer it. Overall, it is a decision that you should make with the doctors treating you. In this case there is not a single answer that is 100% correct.
