In my last post, I discussed what a heart scan score , or coronary calcium score, means.
You may recall that coronary calcium serves as an indirect gauge, a "dipstick," for the amount of atherosclerotic plaque present in the three coronary arteries. Unlike "risk factors" like high LDL cholesterol, high blood pressure, or c-reactive protein, a heart scan score tells you that coronary atherosclerotic plaque, the stuff of heart attack and heart disease, is present and how much.
So, say you have a heart scan score. Perhaps it's even a high value, such as 500. What now?
First of all, don't panic. The vast majority of people who have heart scans are without symptoms. The score signifies that you have some amount of "silent" plaque not causing symptoms. (If you have symptoms of chest pressure, abnormal breathlessness, or similar symptoms, that changes the situation. This will need to be discussed with your doctor and a cause sought, including exploring whether heart disea...
Over the past couple of years, a number of headlines have been published about the significant toll that concussions have taken on retired pro football players’ brains. In some ways, this news wasn’t so surprising when you watch the National Football League’s highlight reels that show absolutely brutal hits that cause a player’s head to snap back or that result in a player landing on his head.
But what about younger players who aren’t playing at the professional level? Are they experiencing any issues with their brains? A new study out of the Laureate Institute for Brain Research in Tulsa, OK tried to determine whether participation in football at lower levels could have a lasting effect on the brain’s hippocampal region or cognitive performance.
First, let’s review where the hippocampus region is in the brain and its responsibilities. This region is located in medial temporal lobe that is found in the front part of the brain. The hippocampus ...
Magnetic resonance imaging - spine; Nuclear magnetic resonance - spine; MRI of the spine; NMR - spine
What abnormal results mean
Spine MRI may reveal disorders such as:
Spinal cord compression
Cervical disk disorders
Lumbar disk disorders
Tumors of the spine
Enlarged lymph nodes
near the spine
Degenerative lesions of the spinal cord
Additional conditions under which the test may be performed:
The sensitivity of MRI depends, in part, on the experience of the radiologist.
