Advanced techniques in cardiac CT imaging – further lowering the effective radiation dose (H. Alkadhi)

posted by Hatem Alkadhi, M.D. | Nov 26, 2009

Cardiac computed tomography (CT) represents a reliable and accurate modality for the diagnosis and exclusion of coronary artery disease. A huge number of studies have investigated the diagnostic performance of CT coronary angiography among different generations of CT scanners. Nevertheless, radiation doses still remain a matter of concern. Read more

Abstract Objective We investigated the performance of low-dose dual-source computed tomography (DSCT) coronary angiography in the step-and-shoot (SAS) mode for the diagnosis of significant coronary artery stenoses in comparison with conventional coronary angiography (CCA). Design, Setting and Patients Prospective, single-center study conducted in a referral center enrolling 120 patients (71 males, age 68 +/-9 … Read more

Case history A 51-year-old male patient, who had suffered a single episode of atypical chest pain a few days prior, was referred to cardiac CT to rule out severe calcification and significant stenoses of the coronary arteries. The patient had a history of high cholesterol as well as a positive family … Read more
