Mr Ankle With Contrast
Can labrum tear (fray) be seen conclusively on MRI without contrast? How about during an arthroscopic surgery of shoulder? MRI with contrast needed?
3D echo, chest Ct with contrast and cardiac MRI MRA MR with gadolinium. Could all 3 miss a vsd or asd? Done at mayo in arizona. I have a CHD PAPVR.
Studies: it is always possible to miss something, even with multiple studies. It is not likely to miss a substantial ASD or VSD with all three studies. You should discuss with your Docs, they can explain to you what your situation is . ...Read more
Only if large enough: MRI with contrast has a resolution limit of about 5 mm, depending on the field strength of the magnet & the spin sequence performed (resolution of time-of-flight MRI or TOF-MRI is even worse). The "gold standard" for an aneurysm is a fluoroscopic angiogram of the brain, which only interventional neurologists or radiologists perform 4 (1) known stroke or (2) genetics.

Allergic to 2 CT scans iodized IV contrast exams, itching, rash. Dr. Wants MRI cervical spine with contrast. Is this a good idea, is this contrast diff?
Yes: Ct scan contrast is totally different than MRI contrast. Ct contrast agents is usually iodinated and are classifed as either ionic or non-ionic. In contrast, MRI contrast agents usually contains chelated gadolinium. Tell the radiologist about your previous ct scan contract allergic symptoms when getting your mri. ...Read moreSee 1 more doctor answer
Difficulty walking after 3 MRI's with contrast,5 CAT scans 3 with contrast 2 Nuclear scans of skeleton with contrast all occurring with in 3 months ?
Difficulty walking: See a neurologist or neurosurgeon. A nerve conduction study and blood work to exclude a polyneuropathy or B12 deficiency is necessary. A metabolic cause rather than a structural cause is likely as the cause of the difficulty walking since imaging studies are nondiagnostic. ...Read moreSee 2 more doctor answers
Yes, ...: Megacolon is suspected in patients with constipation of very long duration, abdominal bloating +/- pain, palpable fecal mass; this is chronic. At times, it can be acute & toxic. Imaging studies of CT scan with/without contrast + barium sulfate confirmed the diagnosis.

Is a 3.0 tesla mra better test than 1.5 tesla mra with and without contrast in detecting and diagnosing 1 to 2 mm cerebral aneurysm(s)?
Yes: magnet strength is highrGet a more detailed answer ›
Is MR arthrography of the hip joint a fancy way of saying MRI of the hip with contrast media (Gadalinium)?
I just had CT scan on Abdomen, Pelvis, & chest With iodine contrast. Would this have shown an aortic aneurysm?
Does siemens avanto " MRA with and without contrast SPGR post coil protocol" has ability to detect small 1 to 2 mm cerebral aneurysm? Expl protocol
More factors: MRA's ability to detect a 1-2 mm aneurysm also depends on the magnet's field strength, number of phase-encoded steps (affects resolution), and acquisition parameters. Given optimal conditions (the above as well as no patient movement), the detection rate of aneurysms larger than 1 mm is comparable for MRA and digital subtraction angiography. www.nlm.nih.gov/medlineplus/ency/article/007269.htm ...Read more
NO: Mri is an imaging device that is independent of function. Think of your car mechanic and a problem with your car. Lifting the hood and looking is like getting an mri. A good mechanic will want to turn it on and drive around and think carefully about what may be wrong. A good brain mechanic will ask appropriate questions and get appropriate tests and think about what may be wrong. ...Read more
Many things: In general areas of abnormal growth such as a tumor or fluid cyst, or areas of swelling such as inflammation or infection. The intravenous contrast solution and swallowed barium help the radiologist identify and separate nearby structures and organs, and help to better visualize possible abnormalities. ...Read more
