    So why after my CT SCAN procedure my right foot feels like it’s going through that iodine warmth on and off after it being one week? Did it remain in my body?

    I am having an MRI no contrast, and then a second MRI with contrast approximately 4.5 hours later. I was told after the first MRI I would get the contrast dye injected (returning later for the second MRI). My question is… will the dye even show up in the MRI if injected 4 or 4.5 hours earlier? Seems a little odd. I was told this is the protocol. I am having an MRI tests of my head for an acoustic neuroma. Thankyou in advance for any answer you can give.

    Luckily studies have shown the heavy metals in contrast are not only good for the body, but are safe and effective! Just like the jab! 😬

    Hii i recently discovered ur channel ...u r doing an amazing job..
    I have a question i recently did my dental xray and my daughter was with me just outside the room but the door wasnttclosed she was about 5 feet away ..
    So i would like to know how far should a perosn stand when taking a xray are there any risk

    • @HowRadiologyWorks

      In general the further the better for reducing x-ray exposure. The exposure of a single dental x-ray is very low and the amount scattered is also a small fraction of that. If you’re daughter is old enough you can ask her to go down the hall next time, but don’t loose sleep over this exposure.

      @@safakhan8599 X-ray radiation cannot be filtrered out completely but it can be reduced to a very low intensity, by having high density material like lead which is usually built into walls. Xray radiation travel in straightlines in vacuum but in air, they get scattered which means they continuously change direction based on probability. To accurately answer your question a medical physicist would have to make a simuation which have to resemble your situation. X-rays can travel to infinity but as i said it's intensity decreases but never goes to 0 (normally 99.99% can be filtered out if you do it correctly with thick lead blocks).

      @@safakhan8599 Allowing a 3-year-old child to undergo a dental X-ray is generally considered safe when necessary for diagnosing dental issues. The exposure to radiation during a dental X-ray is minimal, and dentists take precautions to minimize radiation exposure to children. However, it's essential to follow recommended guidelines for pediatric X-rays, such as using lead aprons and thyroid collars to shield other parts of the body. Always consult with a qualified dentist or healthcare professional for specific recommendations based on the child's dental health needs.

    Hello, how to compare accuracy between CTA and MRA? I have a thoracic aneurysm and I had a big number of CT scans thrown my way. I have to have another CTA soon and that makes me really sick of the thought of getting that much of radiation.

    You're so smart you're blowing my mind. I can wrap my brain around everything you're saying... BUT!
    what's your opinion ?:
    On Intravenous contrast dye with CT...
    How long should a patient wait to try
    to conceive after receiving that specific treatment?
    Do you know what the standard recommendation is for that?
