My mri shows hypolastic right vertibal artery and mild irreularity along the bilaeral segment of internal carotid artery?

My mri shows hypolastic right vertibal artery and mild irreularity along the bilaeral segment of internal carotid artery?

Low value finding.: Why? 2 reasons: 1. Spacial resolution of MRI (even more so than CT) is very low compared to the complexity of the anatomic structures named & 2. Arteries are not being visualized, only a contrast agent within the blood inside the artery. Get & study the image data yourself; compare with Netter anatomy illustrations. Irregularity is c/w artery Ds. Good quality echo of carotid walls far better. ...Read more

Artery (Definition)

Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

Normal variant: The arteries at the base of the brain can course in several different patterns but ultimately get the job done, that is, supply brain tissue. Your pattern is like your fingerprint.
Some more unusual patterns have an increased association with aneurysms, but this would have likely been described if present and vertebro basilar hypoplasia, as in the picture, is pretty common. ...Read more

You are afraid: You may have good reason or not, but I think your doctors can help you understand your conditions or lack of disease better. Ask them for information that is clear to you and also for a referral to a therapist to help you manage your disease anxiety. Understanding = help. If possible, avoid meds that will have side effects as they may just add to your worries. Best wishes. ...Read more

I had parotid surgeries 25 & 20 years ago. I recently experienced TIA. Tests show left carotid artery 30% blocked & right carotid artery 70%.?

I had parotid surgeries 25 & 20 years ago. I recently experienced TIA. Tests show left carotid artery 30% blocked & right carotid artery 70%.?

Focus on carotids: Likely the carotid blockages are due to longstanding deposits of cholesterol and plaques along the inside of the arteries. Coukd be due to high cholesterol or genetics. This is likely what's causing your TIAs as these arteries are the main source if blood into the brain. The lack of blood to the brain can cause TIAs and eventually full strokes. Discuss your options with your doc for treatment ...Read more

Trends: Non-invasive screening for peripheral vascular disease, and extra cranial stenosis, is becoming common, and may well be routine, as part of health maintenance and prevention. These studies are non-invasive, and conducted utilizing ultra-sound techniques. If a block of carotid is noted, this can be handled often by medication, and less often by a fairly safe surgery, to prevent a stroke. ...Read more

What does it mean when an mra shows the intracranial right internal carotid artery is narrowed?

What does it mean when an mra shows the intracranial right internal carotid artery is narrowed?

Depends on degree: An mra can show a area of mild to severe narrowing. Usually this means that there is focal atherosclerosis of the vessel.

The consequence of the narrowing depends on how narrow the vessel is, where the vessel is, and if there are alternative routes for blood to use to reach the area of the brain affected by the narrowed blood vessel. ...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 more

Noticed a pulsating lump in neck, feels like it is directly to the side of carotid artery. Aneurysm or not likely? Clean cervical MRI 6 months ago.

Noticed a pulsating lump in neck, feels like it is directly to the side of carotid artery. Aneurysm or not likely? Clean cervical MRI 6 months ago.

Extremely unlikely: This lump may be due to a curve in the artery or just being closer to the skin. It may not even be the artery! An ultrasound of the carotid arteries will tell the story and is safe and painless. ...Read more

Mri (Definition)

Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
