Application value and detection rate analysis of high-resolution CT scanning technology in pulmonaryinterstitial lesions
高分辨CT扫描技术在肺间质性病变中的应用价值及检出率分析

摘要

目的 探讨肺间质性病变诊断中应用高分辨CT扫描技术的效果。方法 2021年3月到2022年3月，选取疑似肺间质病变患者91例为对象，辅助患者依次应用常规CT扫描技术、高分辨CT扫描技术扫描检查，以临床综合检查为金标准，比较两种技术的检查结果、影像学特征检出率。结果 临床综合检查共检出肺间质病变患者70例，高分辨CT扫描技术的准确性97.80％、灵敏性98.57％、特异性95.24％大于常规CT扫描技术82.42％、85.71％、71.43％（P＜0.05），高分辨CT扫描技术的小叶间隔增厚检出率40.66％、细网状影检出率37.36％大于常规CT扫描技术18.68％、17.58％（P＜0.05）。结论 肺间质性病变应用高分辨CT扫描技术诊断，检查准确性、灵敏性和特异性较好，影像学特征检出率更大，值得临床推广。

Abstract

Objective To explore the effect of applying high-resolution CT scanning technology in the diagnosis of pulmonary interstitial diseases.
Methods From March 2021 to March 2022, 91 patients with suspected pulmonary interstitial diseases were selected as subjects, and the patients were assisted by conventional CT scanning technology and high-resolution CT scanning technology in turn. Taking clinical comprehensive examination as the gold standard, the examination results and the detection rate of imaging features of the two technologies were compared.
Results 70 patients with pulmonary interstitial diseases were detected by clinical comprehensive examination. The accuracy, sensitivity and specificity of high-resolution CT scanning were 97.80%, 98.57% and 95.24%, which were higher than those of conventional CT scanning (82.42%, 85.71% and 71.43%, respectively) (P < 0.05). The detection rate of interlobular septal thickening by high-resolution CT scanning was 40.66% and fine.
Conclusion   High-resolution CT scanning technology is used to diagnose pulmonary interstitial lesions, which has good accuracy, sensitivity and specificity, and the detection rate of imaging features is higher, so it is worthy of clinical promotion.
