DOSE MEASUREMENT USING GAFCHROMIC FILM FOR PATIENTS UNDERGOING INTERVENTIONAL CARDIOLOGY PROCEDURES
1Department of Radiological Sciences, University of Najran, Najran 1988, Saudi Arabia.
Insights
This study measured patient radiation doses during coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA). Results show mean doses of 31.4 Gy cm² for CA and 74.2 Gy cm² for PTCA.
Area of Science:
- Medical Physics
- Radiology
- Radiation Dosimetry
Background:
- Coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) are common interventional cardiology procedures.
- Accurate assessment of patient radiation dose is crucial for radiation protection in these procedures.
Purpose of the Study:
- To evaluate the dose area product (DAP) and entrance skin dose (ESD) for patients undergoing CA and PTCA.
- To utilize GafChromic XR film for accurate dose measurement in a clinical setting.
Main Methods:
- Gafchromic XR film was used to measure entrance skin doses (ESDs).
- Dose area product (DAP) was measured for patients undergoing CA and PTCA.
- ESDs were calculated from DAP measurements.
Main Results:
- The mean DAP for CA procedures was 31.4 Gy cm².
- The mean DAP for PTCA procedures was 74.2 Gy cm².
- The mean ESDs were 0.264 Gy for CA and 0.596 Gy for PTCA.
Conclusions:
- The study provides essential data on patient radiation doses for CA and PTCA.
- Findings can inform radiation dose optimization strategies in interventional radiology.
Abstract:
The aim of this study was to evaluate dose area product (DAP) and skin dose to patients undergoing coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) using GafChromic XR film at King Khalid Hospital, Najran, Saudi Arabia. The entrance skin doses (ESDs) were calculated from DAP using GafChromic XR film placed on the patients back. The mean DAP obtained for patients undergoing CA and PTCA examinations were found to be 31.4 and 74.2 Gy cm2, respectively. The mean ESD using GafChromic XR film was found to be 0.264 and 0.596 Gy for CA and PTCA examinations, respectively.

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...
