had magnetic reasonnance angiogram no significant abnormalties found wats the definition of this doeas it say its clear or just ok wat were they looking for and have i any worries never explained didnt go bk 2 neurologist.
I have no family history of this condition.. I am worried going for a MRA today just to calm my nerves without contrast can anyone help ?
My son in law had a bleeding aneurysm they put in a shunt and took him to angiogram. They couldn't find where it was. I know even a clotted aneurysm should be coiled.
In general, when an aneurysm is found and the size determined on MRA, sometimes (depending on the quality of the MRA and the appearance of the aneurysm on it) another confirmatory test such as a CT angiogram or cerebral angiogram may need to be done to confirm the presence of the aneurysm, confirm its size, and to exclude the presence of additional aneurysms too small to be seen on MRA.
To further evaluate for a carotid artery dissection, a special test similar to an MRI called an MRA (magnetic resonance angiography) can be done to evaluate the blood vessels using special a window known as "fat sats" which optimizes visualization of a dissection. Alternatively, a CT angiogram can be useful.
I was reading up on a Magnetic Resource Angiogram, (MRA) where they inject dye into the vein in the arm and simply take pictures using magnetic imaging, no cather flowing in my arteries.
I would much rather prefer this method but I would like to know will it do a good enough job in detecting plaque build up in arteries as a Coronary Catherization?
I have to have a valve replaced and am having an angiogram to see if there is blockage to be treated at the same time. The physician doing the angiogram has indicated he will put in a stent if he finds blockage. My feeling is that this is unnecessary as the major advantage of angioplasty (less invasive than bypass) is totally irrelevant since I'm having a valve replaced anyway.
Thoughts?
I have no angina and excellent exercise ability. My cardio suggested to get an angiogram to see if it really blocked or just a false positive. I'm scared of the angiogram. Isn't the new 64 slice CT scan just as good to detect blockages as the invasive angiogram?
A CT scan 64-slice angiogram would be an alternative but for someone your young age doctors may be against the procedure due radiation exposure. The procedure includes assessment of the AV, aortic root, ascending, arch and decreasing aorta. Sensitivity is good with MRI and MRA if the software package is designed to image structures. MRI generally has the highest sensitivity of the imaging modalities, with similar specificity to CT and TEE.

can anyone help explain what my MRI/MRA scan results mean:While no definitive aneurysmal dilatation of the intracranial vasculature is evident, there is subtle suggestion of potential fenestration of the M1 segments bilaterally, left slightly more conspicuous than the right. There is no evident hemodynamically significant stenosis or high flow vascular malformation.
The dural venous sinuses demonstrate normal flow-voids.
A nuclear stress test is about 85% accurate in finding CAD whereas a angiogram is 100% accurate. The angiogram also carries a 1 - 3% risk of complications, the most common risk, although very rare, is having an artery dissected during the procedure which results in emergency bypass surgery. Having said that, if I was told I needed one I would do it without hesitation. It is the gold standard of heart tests to determine if CAD is present.
A few years ago, I did a MRI and a MRA, and was diagnosed with a Type II SLAP Tear. Deciding that surgery was too expensive an option, I lived with it.
Presently, I decided to go for surgery as the I could no longer tolerate the pain. Thus I went to an ortho, who put me through a MRI (w/o MRA, claiming contrast is not needed), but the MRI showed that there was no SLAP Tear, but rather a sublabral foramen. Thus, the ortho decided that it was perhaps other factors that was causing the pain.
We have scheduled a MRI-C-spin, MIR-Brain, MRA-Brain and MRA-Neck. I also have scheduled an Echo Cardiogram, an I.V. Persanthine-Thallium stress test and a Holter Monitor.
I cannot drive while wearing the collar but my hustand says he does not want me to drive unless they can tell me why I passed out. I've been told that that is not always possible. Should I refrain from driving if they are not able to pin-point the problem that caused me to black-out?
Hello,
I occasionally have episodes of feeling like I'm on the verge of fainting. Also have episodes of dizziness. When I get these episodes I go to the ER and get checked. EKG's, VS, bloodwork are normal. I've also had a nuclear stress test, and echocardigram fairly recently. Also an MRI, and MRA has been done a couple years back which again were normal. The physician's feel this is stress related. I'm pretty familiar with the "fight or flight response".
