Imaging of intracoronary thrombus by multidetector helical computed tomography angiography.
An 83-year-old woman presented to the emergency department with a 2-hour history of sudden chest pain and dyspnea. An initial ECG demonstrated nonspecific ST changes, and a portable chest x-ray suggested a widened mediastinum. A thoracic multidetector helical computed tomography (CT) angiogram was obtained to assess the possibility of aortic dissection (GE LightSpeed Plus, 2.5-mm collimation wi...
متن کاملCardiac Imaging: Viewpoint adiation Exposure of Computed omography and Direct Intracoronary Angiography
A hallmark of noninvasive testing has been the identification of patients with coronary artery disease. Now, with multislice computed tomography (MSCT), information about coronary anatomy can be obtained without the need for catheterization. A major concern with the application of MSCT coronary angiography is the radiation exposure to the patient. Both MSCT and selective coronary angiography sh...
متن کامل[Radiation exposure in computed tomography].
The axial dose profile of various scans of different CTs was determined to obtain specification on radiation geometry by collimation. The dose was measured "free-in-air" by thermoluminescent dosimeters at the axis of rotation. Considerable differences between the various CTs were observed. The scans of different CTs had narrow and wide fields. It seems to be possible to reduce the energy transm...
متن کاملAssessment of radiation-induced cancer risk to patients undergoing computed tomography angiography scans
Background: Computed tomography angiography (CTA) scan is a suitable imaging technique to evaluate the blood vessels. However, one major disadvantage is the potential risk of cancer related to ionizing radiation exposure during the procedures. The aim of this investigation was to estimate the risk of exposure induced cancer death (REID) values for some common computed tomography angiography (CT...
