Abstract:
Coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) radiation doses were investigated in a recently founded Interventional Cardiology (IC) department. The study includes 336 procedures (177 CAs and 159 PTCAs) carried out with a Philips digital flat detector monoplane system. Patient dose was measured in terms of kerma-area product (KAP) and cumulative dose. Using appropriate conversion factors, peak skin dose (PSD) and effective dose (E) were estimated. Median values of KAP (Gy cm(2)), PSD (mGy) and E (mSv) were: 34 478 and 6.1, respectively for CA and 80 885 and 14.4 for PTCA, within European and international reference levels. Only 1.5 % of patients received radiation dose over the 2 Gy threshold (PTCA procedures) for deterministic effects and none reported any skin effect. Radiation doses were within international standards and comparable with other radiological examinations. The percentage of the high-risk patients for radiation skin effects is extremely low.

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...
