Use of Large Field of View During Image Acquisition for Coronary Angiography

Phase 3

Completed

• Conditions: Exposure to Ionizing Radiation; Occupational Exposure to Radiation; Radiation Injury
• Interventions: Radiation: Large field of view arm; Radiation: Medium field of view

• Registration Number: NCT01334931
• Lead Sponsor: Instituto de Cardiologia do Rio Grande do Sul

Brief Summary

Coronary angiography exposes patients and physicians to ionizing radiation. The purpose of this study is to evaluate the routine use of large field of view during image acquisition for coronary angiography. Patients with indication of diagnostic coronary angiography will be randomized for the use of either large field of view during image acquisition or medium field of view. Patients, physician and nurse radiation exposure will be measured by digital dosimeter.
