The coronary arteries can be extract from these images and be presented in with calamity orient sectional rip. This procedure eliminate substantially of the risk and discomfort associated beside invasive coronary artery catheterization, although it retain the risk basic in radiation bringing to light and costs of evaluation agents.


Martin H. K. Hoffmann, M.D., of University Hospital, Ulm, Germany and colleagues assess the diagnostic accuracy of 16-slice MSCT scan vs. invasive coronary angiography in a ample batch of patients with known or suspected CAD. The chamber, which built-in 103 patients (average age, 61.5 years), be conduct from November 2003-August 2004. The patients sit out both invasive coronary angiography and MSCT using a scanner with 16 detector rows.
