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

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.

Primary outcomes

  1. Patient's radiation exposure

    Time frame: 24 hours

    Patient's radiation exposure will be measured in mGy at the end of procedure

Secondary outcomes

  1. Physician and nurse radiation exposure

    Time frame: 24 hours

    Physician and nurse radiation exposure will be measured in microSv at the end of procedure
