Mr And Mra Abdomen With And Without Contrast
Confused.Ar my request my gastro ordeted abdominal mra.Ct was normal.Order changed by radoologist to do abdominal MRI instead of mra.Scared as to why.
Abdominal MRA: Either the radiologist called your GI doctor and then changed the order, or they are acting inappropriately. Mra stands for “magnetic resonance angiography”. Mra of the abdomen is a quick and accurate noninvasive test to look at the arteries in your abdomen. If there is a risk that your symptoms are due to arterial issues this is the test that should be done. ...Read more
Which test is more accurate in measuring proximal abdominal aorta size in men: ultrasound or mri/mra? Is ap more accurate than tranverse measurement?
Ultrasound: Is the preferred method for screening for abdominal aortic aneurysm as it is less expensive and involves no ionizing radiation. If aortic enlargement is seen, cta is usually chosen to determine most accurately degree of aortic enlargement, extent of aneurysm, and involvement of aortic branches. ...Read more
To rule in or out cerebral aneurysm, usually is mri/mra test done with gadolinium contrast or without.Would mr/mra test with contrast be more accurate?
MR angiography: Can probably detect most aneurysms, and it is always done with gadolinium type contrast. But it is probably not as accurate as an arteriogram, which is more dangerous. Ask your doctor for specific recommendation. ...Read more
If brain mr/mra with/without contrast detects 2 mm pca infundibula, can it also detect 2 to 3 mm brain arterial aneurysm if there is one in same study
It should.: If the study has enough fine (spatial) resolution to see the infundibulum then it should be able to see an aneurysm. Should is the key word. There are many reasons on MRI that something may or may not be seen and the arteriogram (angiogram) is the real final diagnostic study. ...Read more
A few months ago, I started feeling off balance, dizzy almost. Had an MRI without contrast & mra done, found I had a small lesion, is this the cause?
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 ›
If a person had a normal with and without contrast 1.5 tesla mra, should he do 3.0 tesla mra to be sur that 1 to 2 mm cerebral aneurysm was not mised?
Not necessarily: MRA's ability to detect a 1-2 mm aneurysm depends on contrast vs. TOF technique, number of phase-encoded steps, and acquisition parameters. Field strength is another factor, but the data are equivocal for studies of coiled cerebral aneurysms (limited for de novo detection). See your neurologist or neurosurgeon for further discussion. http://link.springer.com/article/10.1007/s00234-008-0413-7 ...Read more
Is an open mra and mrv good enough to diagnose any abnormalities with the blood vessels even without contrast?
For the most part: Both mr angiography (mra) and mr venography (mrv) of the head are usually performed without contrast dye using a special technique that can "see" flowing blood without IV contrast. Open mri? Depends on the machine. Some newer MRI scanners have larger openings without being "open, " and these strike better balance between patient comfort and image quality. May still miss small vascular lesions. ...Read moreSee 1 more doctor answer
Ive had an MRA 'TOF' without contrast dye of the brain done recently. Will this pick up and potential unruptured aneurysms?
