Multislice CT angiography represents one of the most exciting technological revolutions in cardiac imaging and it has been increasingly used in the diagnosis of coronary artery disease. Rapid improvements in multislice CT scanners over the last decade have allowed this technique to become a potentially effective alternative to invasive coronary angiography in patients with suspected coronary ar...
introduction: in patients with coronary artery disease (cad) noninvasive evaluation for detection of ischemia is important to avoid invasive interventions like angiography. exercise stress test is conventionally the first study used in evaluation of cad. considering the noninvasive nature of the myocardial perfusion scan, we decided to compare its accuracy with stress test. methods: patients wi...
Retinal and choroidal vascular imaging is an important diagnostic benefit for ocular diseases such as age-related macular degeneration. The current gold standard for vessel visualization is fluorescence angiography. We present a potential non-invasive alternative to image blood vessels based on functional Fourier domain optical coherence tomography (OCT). For OCT to compete with the field of vi...
Coronary angiography (CAG) is the conventional procedure, considered gold standard for examination of coronary arteries. Being a standardised CAG comparatively safer but an invasive procedure. Therefore, it carries some amount risk compared to computed tomography (CTA). CTA new technique non-invasive and reported be as or more accurate efficient functional stress test in diagnosis CAD comparabl...
