Usefulness Evaluation of Lower Extremity CT Angiography Examination using Heart Rate
The purpose of this study was to find an optimized imaging technique and evaluate its usefulness by comparing and analyzing the difference in contrast enhancement of lower extremity blood vessels according to the patient's heart rate during lower extremity angio CT examination. From January 2022 to August 22nd, 139 outpatients who visited Ajou University Hospital and underwent lower extremity angio CT examination were targeted. According to the heart rate, the groups were divided into four groups: A(HR≤65), B(65
