Mra False Positive Basilar Stenosis
CTA and: Conventional angiography are best for carotid artery stenosis imaging. Ultrasound or Doppler is a great screening test and typically is performed first. MRA often overestimates carotid stenosis due to turbulent flow in areas of narrowing. MRA best for carotid dissection and for patients that cannot receive X ray contrast. CTA is used more often due to invasive nature of conventional angiography. ...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?
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
33 year old female with hypertension and received mra results that show mild to moderate vertebral artery stenosis. What does this mean usually?
Need to be watched: Means you have early narrowing of blood vessels in your neck. Which can progress and cause further narrowing and increase risk of stroke. No surgery needed now, but you have to be on high doses if statins and an Aspirin a day. Repeat carotid doppler every 2 years. If you have high blood pressure or diabetes, should be well controlled. ...Read more
Kidney function worsens on benicar (olmesartan) 20 mg (scr 1.6 to 2.6 in a month) but proteinuria improves. No stenosis in us. Need MRA? Low aldosterone, ok renin.
Depending. ..: What and how the evaluation should be done for individuals should be based on the conclusion of detailed history, physical exam, and preliminary testing. As to yours, which one you need can be deduced by your treating doctor & consultants. Elevating creatinine suggests some impairing blood perfusion through kidneys by fluid contraction + already marginal renal function. More? Ask your doctors... ...Read more
My cervical mra results are: left vertebral artery demonstrates short segment focal high grade stenosis in mid portion. What does this mean? Surgery?
Possibly surgery.: For a young, asymptomatic female it may be the focal stenosis, (narrowing) is developmental, and no rx is needed. However, if there are neurologic symptoms referralable to brain stem function, this finding may indicate need for surgical or neurointerventional treatment. ...Read more

I am a 33 yr fit female with hypertension, white matter changes on MRI and vertebral artery stenosis found in mra. Could I have a stroke soon?
Perhaps.: You are probably at higher risk than average for having a stroke. I would recommend taking an adult aspirin a day and modify your risk factors (blood pressure control, healthy diet, weight loss, smoking cessation, cholesterol control, etc.). Speak to your physician for more information. ...Read more
33 yr old female with hypertension and vertigo, blurry vision and chronic pain. Mra of spine shows vertebral artery stenosis. Could this mean surgery?
It's theLast resort: The first step is to determine if any of your symptoms are related to the stenosis. The next question is the severity of the stenosis. If you have no weakness, cramping, claudication (symptoms with exercise). This may not be the cause of your problems. You should see a doctor with experience in this problem. ...Read more

MRI is sometimes. .:
Useful in mental health situations, especially if there is a history of head trauma, or if there is concern for an anatomic/structural cause for the disorder, like a congenital anomaly (a problem that developed before birth) or a tumor.
Mra would not necessarily be helpful unless the situation or MRI results pointed to a vascular (blood supply) problem. ...Read more
MRI uses electro-magnetic fields which are technically a type of low energy "radiation". There is severe risk if there is metal in the body such as a sliver from an eye injury or some implants.
Clinically concerning radiation is much higher energy and related to x rays, gamma rays, proton or particle therapies, etc. This energy is enough to cause DNA damage. ...Read more
WHY?: Most imaging studies are fully negative in 98% of all patients with migraine, and do not change the symptoms or outcomes at all. You are far better off to locate a neurologist, get this fully evaluated, and treated, as numerous approaches can both prevent and abort migraine headaches. Also, your dizziness could be part of migraine also. ...Read more
