Cumulative Doses of Ionizing Radiation From Computed Tomography: A Population-Based Study

Radiation Doses from Computed tomography in Iraq

Radiation doses to Patient during CT scanner and the radiological risk are significant. Patient dose survey has been conducted toinvestigate the Iraq patient radiation dosesreceived in CT scanners in order to established reference dose levels. These doses are Entrance Surface Dose (ESD),computed tomography dose index(CTDI)), and dose length product (DLP). Two CT scanner were investigated in thi...

Minimizing patient exposure to ionizing radiation from computed tomography scans.

Cumulative exposure to ionizing radiation from diagnostic and therapeutic cardiac imaging procedures: a population-based analysis.

OBJECTIVES The purpose of this study was to describe radiation exposure from cardiac imaging procedures over time in a general population. BACKGROUND Cardiac imaging procedures frequently expose patients to ionizing radiation, but their contribution to effective doses of radiation in the general population is unknown. METHODS We used administrative claims to identify cardiac imaging procedu...

Chest circumference as a predictive parameter of computed tomography coronary angiography radiation doses from dual-source computed tomography.

OBJECTIVE Our aim in this study was to determine the relationship between chest circumference and the radiation doses received by breast tissues during Dual-Source Computed Tomography (DSCT) cardiac scans. MATERIALS AND METHODS Routine cardiac DSCT examinations with similar exposure lengths were applied to 30 female patients. The scanogram image, multi-slice helical scan x-ray tube voltage an...

Radiation doses to emergency department patients undergoing computed tomography.

OBJECTIVES Computed tomography (CT) use is increasing in the emergency department (ED). Many physicians are concerned about exposing patients to radiation from CT scanning, but estimates of radiation doses vary. This study's objective was to determine the radiation doses from CT scanning for common indications in a Canadian ED using modern multidetector CT scanners. METHODS We conducted a hea...
