Computed tomography coronary angiography.
Recent developments in computed tomography technology have made imaging of the coronary arteries possible. All the same, the rapid motion and small dimensions of the coronary vessels make coronary computed tomography angiography (coronary CTA) challenging. With the last generations of 16- and 64-slice computed tomography and adequate patient preparation (which includes lowering of the heart rat...
متن کاملCoronary Computed Tomography Angiography
Coronary computed tomographic angiography (cCTA) as a noninvasive approach underlies a rapid technological development with an impressive improvement of spatial and temporal resolution of the images. Therefore, it has become an accurate and costeffective method to detect or exclude obstructive coronary artery disease (CAD) in patients with low to medium cardiovascular risk profile, as recommend...
متن کاملCan coronary computed tomography angiography replace invasive angiography? Coronary computed tomography angiography cannot replace invasive angiography.
O ne million patients undergo invasive coronary angiogra-phy (CA) in the United States every year. 1 In view of its invasive nature and related costs, noninvasive imaging of coronary imaging has the theoretical appeal to improve comfort for patients, reduce cost, and refine patient selection to limit invasive procedures to patients requiring treatment for ischemic coronary artery disease (CAD)....
متن کاملReducing computed tomography radiation dose in diagnosing pulmonary embolism
BACKGROUND AND OBJECTIVE Computed tomography angiography plays a major role in the diagnosis of pulmonary embolism. Radiation dose associated with it is a major concern; therefore it is important to optimize protocols and techniques to ensure minimum radiation dose. METHODS The study compares two protocols i. Conventional Timing Bolus CT protocol and Delayed Timing Bolus protocol used to assi...
متن کاملTemporal Trends in Radiation Dose Associated with Coronary Computed Tomography Angiography
Background: In 2010, the International Atomic Energy Agency launched the “3A’s campaign” as an effective tool for primary cancer prevention. In 2011, the American Association of Physicists in Medicine recommended the size specific dose estimate (SSDE). Objectives: To audit doses of Coronary CT Angiography (Coronary CTA) in tertiary care referral center. Methods: We reviewed 998 consecutive Coro...
