Radiation dose from single-heartbeat coronary CT angiography performed with a 320-detector row volume scanner.
PURPOSE To determine radiation doses from coronary computed tomographic (CT) angiography performed by using a 320-detector row volume scanner and evaluate how the effective dose depends on scan mode and the calculation method used. MATERIALS AND METHODS Radiation doses from coronary CT angiography performed by using a volume scanner were determined by using metal-oxide-semiconductor field-eff...
متن کاملDose exposure of patients undergoing comprehensive stroke imaging by multidetector-row CT: comparison of 320-detector row and 64-detector row CT scanners.
BACKGROUND AND PURPOSE Recently introduced 320-detector row CT enables whole brain perfusion imaging compared to a limited scanning area in 64-detector row CT. Our aim was to evaluate patient radiation exposure in comprehensive stroke imaging by using multidetector row CT consisting of standard CT of the head, CTA of cerebral and cervical vessels, and CTP. MATERIAL AND METHODS Organ doses wer...

متن کاملNovel 320‐slice multislice CT angiography as a gatekeeper for invasive coronary angiography
The diagnostic accuracy of 64‐slice CTA, currently the most widely used CTA system, has been well established by several multicenter studies [4–6]. In a recent prospective multicenter, multivendor trial by Meijboom and coworkers, high diagnostic accuracy of 64‐slice CTA was observed in the evaluation of 360 symptomatic patients with acute and stable angina [5]. On a per‐patient basis, the sensi...
متن کاملCoronary computed tomography angiography with 320-row detector and using the AIDR-3D: initial experience
Coronary computed tomography angiography (coronary CTA) is a powerful non-invasive imaging method to evaluate coronary artery disease. Nowadays, coronary CTA estimated effective radiation dose can be dramatically reduced using state-of-the-art scanners, such as 320-row detector CT (320-CT), without changing coronary CTA diagnostic accuracy. To optimize and further reduce the radiation dose, new...
