MRA or CTA

Posted by waterwoman9 @waterwoman9, 20 hours ago

How is an MRA or CTA different from the standard MRI and CT? I am having one due to possibility of an unruptured aneurism. I understand that unruptured aneurisms are not serious unless at some point it does actually rupture. Has anyone experienced an unruptured aneurism?

Interested in more discussions like this? Go to the Brain & Nervous System Support Group.

"The studies showed that, compared with invasive coronary angiography, coronary CT angiography had a sensitivity of eighty versus sixty-seven percent and a specificity of sixty-seven versus seventy-five percent."
