Non Contrast Mri
Non contrast MRI was clear. No tumor or other issues found. Should I request an MRI with contrast or would the non contrast show issues?
Whi MRI in first pal: You need to tell us about your general condition as to why was the MRI done in the first place? Contrast is often used but it only enhances to show a lesion better. Most serious abnormalities will show up on MRI even without the use of contrast. Yet if your symptoms persist, a repeat MRI with Contrast may be necessary. What was your main symptom to do a MRI??? ...Read more
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
No: The MRI needs to be with contrast. Also, there is no specific findings on MRI that will diagnose vasculitis. An MRI will show white matter lesion consistent with vasculitis but the same lesions are also consistent with several other causes including lyme disease. You should address all of your numerous questions to a rheumatologist. ...Read more
I recently had a non contrast MRI of the brain. It came back normal. Would they have seen a tumor if I had one?
Would a non-contrast MRI show a tumor located on the skull? Are there limitations? Bony protrusion?
Depends: Depends on tumor. If there's a lot of calcium in the tumor then, contrast may not be needed to see it. If it's a meningioma then, contrast may not be necessary because of the Dural Tail sign seen on FLAIR images, however, contrast is generally given to PROVE it. But in other cases tumors may be hidden if small, no mass effect, and no contrast. Contrast always best if mass suspected. ...Read more
Recent/non contrast MRI normal. Blood wrk normal. Stabbing pains in left side of head. Worse when bending over. Any suggestions?
Functional disorder: You were probably led down the wrong path, but your question is worth posing to whoever ordered the MRI since s/he (1) must have thought about what the problem was before ordering & (2) have the official MRI report. Just from what you wrote, I think you have a migraine or vascular headache condition (which won't be seen on any imaging study) but I could be wrong. Use HealthTap Prime to verify &ask ...Read more

Is it safe to have a non contrast MRI of the neck the day after having a lower wisdom tooth pulled? Just anxious.
Got postural orthostatic tachycardia syndrome. I am getting a brain MRI just for completeness nothing specific. Will a non-contrast MRI be of value?
Yes: The non-contrast brain MRI is certainly useful to look for any structural lesions that could be the cause of your symptoms. There are many sequences that they do to look for stroke, white matter disease, mass lesions or CSF abnormalities. The contrasted scan is good for delineating a tumor. These can also be seen on the non-contrasted scans if they are large and special sequences are done. ...Read more
Is it possible for a c-spine lesion to show up on a non-contrast t-spine MRI (in the initial focus view), or is it always going to be an artifact?
Possible..: The T-spine MRI may show the lower C-spine components which are adjacent to the upper T-spine vertebra, so even though this could be an artifact it is not because of the location but rather because of the technique or the image itself. If it needs definition and confirmation a C-spine MRI should be done. ...Read more
Drink Fluids: Allergic reaction from gadolinium dye is extremely rare. However, if you experience symptoms such as rash, hives, or shortness of breath, you should notify the technologist immediately if you are still at the imaging facility, or call your doctor or go to the nearest hospital if you have already left the imaging facility. In addition drink plenty of fluids. ...Read more
Diverticula, sacs: or pouches formed from a cavity or tube, can develop in a number of organs...the colon, urinary system, etc. So I'm not sure where yours is. The colon is most common in men, but MRI is not a super common test to detect them. A diverticulum is not harmful in and of itself but it can become inflamed and infected causing diverticulitis. Somewhat unusual in a young male, so work closely with your Doc ...Read more
An injection: Mri or magnetic resonance imaging uses a strong magnet to obtain detailed images of the body. The machine is shaped like a large donut. Sometimes contrast material or contrast dye is injected into a vein (usually in the arm) to see certain structures better. ...Read moreSee 1 more doctor answer
