Radiation Dose Reduction By Using The Modified Method For Imaging The Right Coronary Artery
Introduction. A modified imaging technique for the right coronary artery (RCA) has been developed to reduce radiation dose and fluoroscopy time. Methods. This study compared patient and operator exposure to ionizing radiation (mGy) and fluoroscopy time(s) during RCA imaging using standard and modified methods. Results. The modified technique resulted in significantly lower radiation dose (23.78 vs. 34.78 mGy; p < 0.001). Conclusion. The modified RCA imaging technique substantially decreases radiation exposure, fluoroscopy duration, and contrast volume, improving safety for both patients and staff.
