NCT01111760 | Completed

• 1 other identifier: HIC 2010-082
• Study Type: observational
• Target: 334
• Locations: 1 country

Brief Summary

The purpose of this study is to compare the radiation exposure of a variety of chest CT examinations performed on the current state of the art CT scanners (64 slice, dual source CT scanner) with the radiation exposure for identical chest CT examinations performed on the Siemens Flash CT scanner (high pitch dual source spiral technique).

Conditions

Atherosclerosis of Coronary Artery; Cardiovascular Disease; Pulmonary Embolism; Aortic Aneurysm Without Mention of Rupture Nos

Keywords

cardiovascular disease; heart CT scan; CT scan; pulmonary embolisms; aortography

Outcome Measures

Primary Outcomes (1)

• Comparison of the radiation dose for chest CT examinations using current technology with radiation dose exposure using the newest generation CT scanner.

  The primary objective of this study is to compare the estimated radiation dose for chest CT examinations (cardiac and non cardiac) performed using current technology (ie. Retrospective gated CT examinations on the 64 slice and dual source Definition Siemens CT scanners) with the radiation exposure using the newest generation CT scanner (high pitch dual source spiral technique).

  Time of CT scan
