Can labrum tear (fray) be seen conclusively on MRI without contrast? How about during an arthroscopic surgery of shoulder? MRI with contrast needed?

Can labrum tear (fray) be seen conclusively on MRI without contrast? How about during an arthroscopic surgery of shoulder?  MRI with contrast needed?

Labrum tears: can be seen on routine MRIs is they are large or severe. MRI with intrarticular contrast(MR arthrogram) is much more accurate, particularly for smaller tears. Arthroscopy will show labral tears. ...Read more

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.

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

Can a brain aneurysm show on MRI with contrast?

Can a brain aneurysm show on MRI with contrast?

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. Use HealthTap Prime to discuss ...Read more

What will an MRI with contrast reveal about a knee injury that won't show with out contrast?

What will an MRI with contrast reveal about a knee injury that won't show with out contrast?

MRI: I'm assuming you mean intra-articular contrast (arthrogeam). It adds additional detail making more subtle injuries more clear (ie small cartilage tears, cartilage erosion, etc). Simply put...Contrast adds clarity. Even more useful for shoulders. ...Read more

Enhancement: Contrast causes enhancement of certain structures, like abscesses, making them much easier to see. In addition, the differential diagnosis hinges sometimes on whether a structure enhances or not with contrast. ...Read more

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?

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 more

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 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 more

Would Megacolon be seen on abdominal/pelvic CT scan with contrast and barium sulfate?

Would Megacolon be seen on abdominal/pelvic CT scan with contrast and barium sulfate?

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. For future events of health concern, follow the instruction in articles listed in http://www.formefirst.com/onDealSickness.html. ...Read more

Could a cta chest scan with IV contrast detect problems with the heart?

Could a cta chest scan with IV contrast detect problems with the heart?

Not best: Test for heart but sometimes we see things like coronary artery disease and large atrial septal defects. Aortic valve disease can sometimes be seen. Best to have appropriate test for the portion of the heart your doc is worried about. ...Read more

Would pancreatitius show on a abnominal CT w/o contrast but with barium shake?

Pancreatitis: It can. You can see inflammatory changes around the pancreas. It would be difficult to assess for necrosis of pancreatic tissue which is seen in severe pancreatitis without IV contrast though. ...Read more

Can a pelvic/abdominal CT scan with barium and IV contrast detect back problems and sciatica?

Can a pelvic/abdominal CT scan with barium and IV contrast detect back problems and sciatica?

Some: The Radiologist will definitely be able to see your spine. The images from a CT of the abdomen are not formatted specifically to look at the spine however. The test of choice to evaluate sciatica is an MRI. ...Read more

Is MR arthrography of the hip joint a fancy way of saying MRI of the hip with contrast media (Gadalinium)?

Is MR arthrography of the hip joint a fancy way of saying MRI of the hip with contrast media (Gadalinium)?

Yes and no.: A standard MRI with contrast usually implies an intravenous injection of gadolinium. An MRI arthrogram means that the contrast is injected directly into the joint space, usually with fluoroscopic guidance of the needle. ...Read more

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

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

Can an MRI scan show cognitive impairment?

Can an MRI scan show cognitive impairment?

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

What can an abdominal CT scan with IV dye and barium sulfate solution find?

What can an abdominal CT scan with IV dye and barium sulfate solution find?

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
