Which test is more accurate in measuring proximal abdominal aorta size in men: ultrasound or mri/mra? Is ap more accurate than tranverse measurement?

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

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

Vl carotid bilat post TIA found:l internal carotid stenosis 50-79% by velocity. F/u with neck contrast mra, shows nothing normal study! how can it be?

Vl carotid bilat post TIA found:l internal carotid stenosis 50-79% by velocity. F/u with neck contrast mra, shows nothing normal study! how can it be?

Velocity accurate: Most likely accurate ultrasound. Repeat at 6 months. Unlikely a dissection with resolution- but possible. Or increased flow after tia? Would be unusual. Mra has value but some limitations of stenosis measurements. ...Read more

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?

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
