Objectives: CT angiography (CTA) is gradually replacing digital subtraction angiography (DSA) in the etiologic workup of intracranial hemorrhage, though debate persists regarding its diagnostic accuracy. To better define the role of CTA in a pragmatic, real-world setting, we reviewed the experience ...
Functional MRI (fMRI), for example, creates brain maps of nerve cell activity second by second and is helping researchers better understand how the brain works. Magnetic resonance angiography (MRA) creates images of flowing blood, arteries and veins in virtually any part of the body. Hydrogen ...
The purpose of this study was to evaluate the quality of dual-source CT images of the coronary arteries in heart transplant recipients with high heart rates.Contrast-enhanced dual-source CT coronary angiography was performed on 23 heart ... Gorka,Bastarrika,Carlo,... - 《Ajr American Journal ...

Fundamentally, cardiac imaging is a straightforward extension of the principles underpinning stationary vessel CT angiography (CTA), though the beating heart introduces some new issues for data acquisition and processing. Although the application of mechanical helical CT for coronary imaging ...
Angiogram:This imaging technique may involve an X-ray, MRA (magnetic resonance angiogram), or CTA (computed tomography angiography). Angiogram differs from other imaging techniques in that it also involves the injection of contrast dye into the blood to provide a detailed look at blood vessels and...
Angiography Doctors inject a dye into a vein before you get a CT scan or MRI. The dye helps to show where the trouble is. In some cases, doctors use angiography to inject a medicine that may stop the bleeding. Radionuclide scanning ...
"Overall, we estimated that approximately 29 000 future cancers could be related to CT scans performed in the US in 2007. The largest contributions were from scans of the abdomen and pelvis, chest, and head, as well as from chest CT angiography. One-third of the projected cancers were due...
Magnetic resonance angiography (MRA) is expected to disclose this process since it can be conducted frequently because of its non-invasive nature. In this study, we prospectively investigated postoperative neovascularization using repeated MRA. Methods We studied 14 pediatric patients (23 sides) who ...
