Abstract:
The aim of this work was to evaluate and quantify the impact of an invasive training of cardiology fellows on some exposure parameters. From 1 January 2000 to 31 December 2002, three staff members performed 2.582 diagnostic procedures (Group 1) that were compared with 819 performed by, or with the participation of five cardiology fellows (Group 2). Exposure parameters were as follows (Group 1/Group 2): fluoroscopy time 3.8 +/- 4.5/5.5 +/- 5.9 min (+38%), mean number of frames 589 +/- 282/642 +/- 260 (+9%), Kerma-area product (KAP) during fluoroscopy 10.6 +/- 14/15.5 +/- 16 Gycm2 (+45%), KAP during cine-angiography 20.8 +/- 14/22.5 +/- 12 (+8%), total KAP 31.5 +/- 28/38.1 +/- 28 (+21%). Differences were all significant (P

Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
