Prospective-triggered high-pitch spiral versus sequential dual-source CT coronary angiography: comparison of image quality and radiation dose
Background: Prospectively electrocardiography (ECG)-triggered high-pitch spiral coronary computed tomography angiography (CCTA) is a unique scan mode for dual-source CT (DSCT). Our reports aim to compare image quality and radiation dose of CCTA using high-pitch spiral or sequential acquisition mode in patients with low and stable heart rates. Materials and Methods: Patients with low and stable ...
متن کاملRadiation Dose and Risk of Cancer from CT Scans
Setting and participants. Data were collected at 4 large hospitals in the San Francisco Bay area. The most frequent CT study types were determined through querying the radiology information system at the University of California, San Francisco, for all CT examinations performed in a single month. The 11 most common study types not performed in association with a therapeutic procedure were selec...
متن کامل[Coronary CT angiography using a prospective protocol. Comparison of image quality and radiation dose between dual source CT and single source CT].
OBJECTIVE To compare the image quality and radiation dose in a group of patients undergoing coronary CT angiography using a 128-slice dual source helical CT scanner with high pitch alto and prospective acquisition with those in a group of patients with similar clinical characteristics undergoing coronary CT angiography using a 128-slice single-source CT scanner with prospective sequential acqui...
متن کاملImage Quality and Radiation Dose for Prospectively Triggered Coronary CT Angiography: 128-Slice Single-Source CT versus First-Generation 64-Slice Dual-Source CT
This study sought to compare the image quality and radiation dose of coronary computed tomography angiography (CCTA) from prospectively triggered 128-slice CT (128-MSCT) versus dual-source 64-slice CT (DSCT). The study was approved by the Medical Ethics Committee at Tongji Medical College of Huazhong University of Science and Technology. Eighty consecutive patients with stable heart rates lower...
متن کاملInclusion of the dose from kilovoltage cone beam CT in the radiation therapy treatment plans.
PURPOSE Cone beam CT is increasingly being used for daily patient positioning verification during radiation therapy treatments. The daily use of CBCT could lead to accumulated patient doses higher than the older technique of weekly portal imaging. There have been several studies focusing on measurement or calculation of the patient dose from CBCT recently. METHODS This study investigates the ...
