Usefulness of an Anisotropic Diffusion Method in Cerebral CT Perfusion Study Using Multi-Detector Row CT
Purpose: To present an application of the anisotropic diffusion (AD) method to improve the accuracy of the functional images of perfusion parameters such as cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) generated from cerebral CT perfusion studies using multi-detector row CT (MDCT). Materials and Methods: Continuous scans (1 sec/rotation ×60 sec) consisting ...
متن کاملRadiation 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 کاملVolumetric perfusion CT using prototype 256-detector row CT scanner: preliminary study with healthy porcine model.
This is a preliminary demonstration of volumetric perfusion CT of the brain in domestic pigs by using a prototype 256-detector row CT. Scan range is approximately 100 mm in the craniocaudal direction with 0.5-mm section thickness. The 256-detector row CT is an easily available imaging technique that can provide volumetric cine imaging, CT angiography, and perfusion CT in a wide craniocaudal cov...
متن کاملEvaluation of patient dose and operator dose in swallowing CT studies performed with a 320-detector-row multislice CT scanner.
Recently, attempts to develop new types of swallowing function analysis with 320-detector-row multislice CT (320-MDCT) have been reported. The present report addresses (1) patient exposure, (2) operator exposure, and (3) spatial dose distribution. For dose measurement, a human-body phantom in which 303 thermoluminescent dosimeter elements were inserted and a survey meter was used. The patient p...
