I read somewhere MRI has no radiation and CT scan is the highest dose. Flight is like around 4 xrays.
is the 3-d generated from a regular CT of slices? or is it a special process. The slices in mine show just what falls in that view so to see the whole thing you have to scroll through 3 or 4 in the area. But the slices from top to bottom of my head showed the bone pushing my left carotid in-so surgery stopped that-they were concerned that it had worn down the muscle of the artery and were prepared to sew it up during surgery if needed. wow it wasn't. But that is one of those issues that come up due to delaying removal for years. Taking it out asap would lesson the chronic symptoms. My right side has no symptoms after surgery. the left one does and only time will tell is some of it heals without the spike in it.
I don't think MRI's have radiation-they use electromagnets and cause a large magnetic field.
I read that a CT is the x-ray exposure from 30 to 400 single x-rays. a lot of disagreement. either way I am my own nightlight by now--I've also had live fluoroscopy which is greater still.
Eagle's Syndrome pet peeve with Doctors........ How many ways do we have to prove to doctors that we have this. Doctors should know and get the single most definitive scan and operate from that. One single Panorex got me surgery in 1990. But with this one it was 15 years of x-rays, CT's all showing the same thing. So what is the goal? to bore us away.
is there a method to scan an x-ray? I have a few that show it better than the CT ever did. # weeks ago I was told by a radiologist that CT's are crude and don't capture all of anything. direct view or x-ray with contrast works. but the CT slices work ok but the whole thing is spread across the slices as you go through them.
I've been told that MRI's have no radiation and CT scans have a LOT - the equivalent to 90 x-rays, or something like that. Some big number.
ooo Well that is a lot, well still no extra toes here! And yes my fault I mean x ray not MRI, should have just talked about how MRI is useless but always seems to come before you get a CT Scan and the CT takes 20 seconds to do.
As for shaw, I am preety positive they image a 3d ct scan with several slices and then use a software program that pieces it all together, on my cd I have several different types of images from several sides, only the last image out of all 20 was the 3d picture which I could manipulate 360 degrees.
