Abstract

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

下肢CT血管造影心率检查的有效性评价

本研究的目的是通过对比分析下肢血管CT检查时根据患者心率对下肢血管造影增强效果的差异，寻找一种优化的成像技术，并评价其实用性。研究对象为2022年1月至8月22日在亚洲大学附属医院就诊并行下肢血管CT检查的139例门诊患者。根据心率分为A组(HR≤65)、B组(65
