Measurement of Patient Dose in Vascular Intervential Radiography
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2016, Vol 4, Issue 3
Abstract
Cardiac catheterizations have contributed greatly to the treatment of heart diseases. However the radiation exposure to the patient is significantly higher compared with other radiological examinations. The objectives of this study are to evaluate the level of radiation dose received by the patients in order to introduce local diagnostic reference levels. A total of 108 consecutive patients who underwent cardiac catheterization using Dose-area product (DAP) were measured. The mean of DAP ± SD of therapeutic and diagnostic cardiac catheterization procedure was (80.84 ± 25.09) mGy.cm2 and (67.04 ± 26.65) mGy.cm2 respectively and for; male, female and total was (74.87± 41.33, 72.52± 27.91 and 73.84± 35.75) mGy.cm2 respectively. The mean of fluoroscopic time ± SD of therapeutic and diagnostic cardiac catheterization procedure was (6.10 ± 4.51 and 5.31 ± 2.96) minutes respectively and for male, female and total was (7.6±6.67, 5.90±3.70 and 6.89±6.26) minutes respectively. The mean of entrance surface dose ± SD of Therapeutic and diagnostic cardiac catheterization procedure was (80.8384± 25.08, 67.0351± 26.649) mGy respectively, and for male, female and total was, (74.87 ± 41.33, 72.52 ± 27.91 and 73.84 ± 35.74) mGy respectively. The study concluded to the fact that the patients received relatively high dose but the dose is necessary to enable the diagnosis or treatment and there are still minor differences with global standards.
