Mra False Positive Basilar Stenosis
Spinal cord lesion on t3/4, negative brain mri, positive for oligoclonal banding. Neurologist says ms. Can this be with negative brain mri?
Debatable: Few vascular surgeons make decisions on carotid artery stenosis based on mr, as carotid doppler (ultrasound) has been proven to be very reliable when a good technologist performs the study. From what you're describing, your carotid arteries are likely without disease as the reporting standards for ultrasound haven't quite been set. In my lab you'd likely be found to have no disease at all. ...Read more
Brain MRI says satisfactory intraluminal signal is noted in distal carotid vertebral and basilar arteries. Unremarkable brain MRA. What does this mean?
Normal vessels.: means normal vessels.Get a more detailed answer ›
Can L-carotid artery hypoplasia cause temporary R-eye blindness? CTA, CT, MRI show only L-side abnormalities and a 3mm aneurysm
When measuring ascending aorta size(horiz)from sinotobular junction to innominate artery is cardiac mri/mra for morphology more accurate test than cta?
Depends: Done properly, ideally with ECG gating, an aortic MRA is equivalent to an aortic CTA. The opinion from some vascular docs is an overestimation on MRA. This was probably from movement artifact and older scanners. The benefit of MRA is the lack of iodinated contrast and lack of radiation. It is in routine use at many large medical facilities to periodically track aortic enlargement- kids/adults ...Read more
Would a regular MRI w/contrast on brain reveal severe vertebral artery insufficiency/stenosis causing vertigo?
Husband had eye stroke had dopplar & mta dopplar showed blood flow no blockage mta showed severe stenosis carotid artery how does this happen next cta?
Carotid stenosis: If severe, greater than 60%, then you should consider a potential entarterectomy or even stunting to prevent additional stroke events. Some evidence to suggest also, potential benefit of anti-platelet medication such as Aggrenox and a statin. Discuss with a stroke neurologist, and a vascular surgeon. ...Read more
How can a dopplar test and mra on a carotid artery show different results dopplar-no blockage mra-severe stenosis happened to my husband now cta next?
Doppler: Is technician dependent and mra can sometime overestimate the degree of stenosis. Cta is the test of choice for carotids. Angiogram remains the gold standard but not commonly done any more since it is more invasive and does carry a small risk of stroke. ...Read moreSee 1 more doctor answer
I was told a Ct 64 slice Ct angio, 3d,ultrasound, cardiac MRA MRI, Ct chest with contrast and stress test cannot detect soft plaques? True or not true
Carotid artery disease, what to believe, if different results from duplex ultrasound vs. Ct angiogram (cta)?
Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?
Does Central Pontine Myelinolysis (after a hypernatremic state) always show up on MRI? Other test results?
Coronary Angiography report concluded;"atherosclerotic coronary artery disease showing moderate proximal LAD mixed stenotic lesion 50%"what it means?
Test Result: I find it is best to discuss any test result with the physician who did the test or ordered the test. They can interpret it knowing all the clinical history involved and tell you exactly what is going on. ...Read more
Echocardiogram results indicate an avm. CT scan of chest and MRI & mra of brain still negative. where else might the avm be, what does thi mean?
Anywhere: AVM's can be anywhere including the brain, lungs, intestines. Dr. Rich White at Yale runs the world class HHT center for patients with AVM's in multiple vascular beds. ...Read more
Periventricular isch chnges, infarcts both cerebral hemispheres incl rt parietal? Vascular event.Blood & vessels ok.Next check pfo, but could it be ms
Possible, but...: Fine to check for pfo, but real question involves potentials for stroke. You could have cadasil, which is a genetic disorder. A spinal tap could assist in diagnosis perhaps. Vasculitis, arteritis, even sjogren's might be considered. Description not necessarily ms, but part of considerations. ...Read more
Best non invasive test to check coronary arteries? Ct angio, stress echo and cardiac MRI MRA? Any better non invasive testing to check coronary art?
Tests: Each of the tests listed has specific strengths and weaknesses. The choice of study depends on the specific information desired by the ordering physician and the capabilities of the performing laboratory. CT angio in many cases will produce the best images of the arteries of the three, MRA has its specific indications and stress echo doesn't show the vessels but shows the effects of serious ischem ...Read more
Probably not: A cardiac echo/Doppler study would show pulmonary HTN changes by viewing the right ventricular function , size and pressure. There are additonsl studies that can also be done. It is very important to know WHY you have Pulmonary HTN. If due chronic Pulmonary embolism it is a serious situation for which there exists very effective Rx. Other causes can also be treated. Consult your doc. ...Read more
