Is Ct Or Mri Contrast Safe With Porphyria
I have acute porphyria: can I do the following: take a flu shot, donate my organs, take a cat scan with the contrast?
Yes& no: Now that swine flu vaccinations have begun in some areas, members with acute porphyria (aip, vp, hcp & adp) will be relieved to know that it is fine for them to receive flu and other vaccines. In fact, since other illnesses can bring on a porphyria attack, remaining healthy is one of the most important ways to prevent acute attacks. No organ donnation?No if you allergic to idione? ...Read moreSee 1 more doctor answer
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
Is it safe to do MRI with contrast to see AVM / aneurysm if i had at CT with contrast anaphylaxis shock ? Or how can do it otherwise ? Thank a lot.
Different: X-ray (CT) contrast is iodine based and allergic reactions are fairly common. MRI uses Gadolinium which is completely different and allergic reactions are rare. Here is a reference: http://www.medicalnewstoday.com/releases/92774.php I'm not aware of any cross-reactivity but the radiologist supervising your study will know for sure. Mention your previous reaction to them. ...Read more
I have hypothyroidism. Is it safe to have a CT scan w/ contrast? If an MRI alternative? I also have a Harrington Rod in my back. Any alternative.
Thyroid and CT: If your hypothyroidism is appropriately treated there is nothing to worry about. If you do not have renal impairment, then the use of contrast should be safe. Every test, including a CT, is a balance of risks and benefits. If you need the CT, then go with your doctor's advice. ...Read more
Both are safe.....: Mri has no ionizing radiation, thus there is no risk of radiation induced cancer. However, MRI is not for everyone. If you are claustrophobic, have a heart pacer, or have shrapnel you may not be able to have an mri. Ct does have radiation, but the dose is very small and in most cases less than you are exposed to just by living on earth for one year. You, your doc and radiologist should decide. ...Read moreSee 1 more doctor answer
Not same: Mri contast gadolinium does not contain iodine while ct contrast contains iodine. An allergic reaction to ct contrast does not mean that you will have a reaction to gadolinium during your MRI scan. True allergies to the MRI contrast are exrtremely rare; however, you may still experience some symptoms like feeling lightheaded or nauseated due to the injection. Good luck with the exam! ...Read more
Either: Either a ct with and without contrast or an mr exam seem treasonable approaches. I may slightly favor the mr exam. ...Read more
Need to talk with : Your ordering doctor. Depends on what is being evaluated, and the differential diagnosis. Ct is a good quick screen for bleed, masses, skull fractures, etc. And MRI gets you good soft tissue details, and lets you better evaluate the gray and white matter, also allows you to evaluate bleeds, helps you tell if old or new bleed, also helps you see tumors, strokes (ischemic areas, atrophy, etc.). ...Read moreSee 1 more doctor answer
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
