CT动态增强扫描联合超声引导下肝穿刺活检诊断肝脏占位性病变的价值

摘要/Abstract

摘要： 目的本研究旨在分析CT动态增强扫描联合超声引导下肝穿刺活检诊断肝脏占位性病变的价值。方法纳入2020年11月至2024年11月界首市人民医院收治的恶性肝脏占位性病变患者95例,患者均接受超声引导下肝穿刺活检,根据是否接受CT动态增强扫描,将患者分为对照组和观察组,比较两组出血情况、组织条长度和检测结果。结果在本组95例患者中,55例接受CT动态增强扫描(观察组),40例未接受CT动态增强扫描(对照组)。对照组中出血5例,均为渗出,进行压迫法止血后恢复正常,观察组中无出血现象(χ²=7.257,P=0.007)。对照组和观察组的有效病理组织条长度分别为(15.84±2.02)mm和(17.62±2.31)mm,观察组比对照组增加(t=3.975,P<0.001)。对照组采用超声引导下穿刺活检的诊断阳性率为75.00%(30/40);观察组采用CT动态增强扫描联合超声引导下穿刺活检的诊断阳性率为92.73%(51/55);观察组检测准确率更高(χ²=5.792,P=0.016)。结论 CT动态增强扫描联合超声引导下肝穿刺活检诊断肝脏占位性病变可减少患者出血风险,并提高诊断准确度。

Abstract: Objective To investigate the diagnostic value of CT dynamic contrast-enhanced imaging combined with ultrasound-guided liver biopsy in diagnosing hepatic space-occupying lesions. Methods Between November 2020 and November 2024, 95 patients with malignant hepatic space-occupying lesions were encountered in Jieshou People′s Hospital. All patients underwent ultrasound-guided liver biopsy. Based on whether they received CT dynamic contrast-enhanced scanning, tissue strip lengths and test results were compared between the two groups. Results Among the 95 patients with malignant hepatic space-occupying lesions in this group, 55 patients received CT dynamic contrast-enhanced scanning (the observation group), and 40 patients did not (the control group). In the control group, 5 patients had bleeding, all of which were exudative. After compression for self-hemostasis, they returned to normal. No bleeding was observed in the observation group (χ²=7.257, P=0.007). The lengths of effective pathological tissue strips in the control group and the observation group were (15.84±2.02) mm and (17.62±2.31) mm respectively. The length in the observation group was longer than that in the control group (t=3.975, P<0.001). The positive rate of diagnosis by ultrasound-guided biopsy in the control group was 75.00% (30/40). The positive rate of diagnosis by CT dynamic contrast-enhanced scanning combined with ultrasound-guided biopsy in the observation group was 92.73% (51/55). The detection accuracy of the observation group was higher than that of the control group, and the difference was statistically significant (χ²=5.792, P=0.016). Conclusion CT dynamic contrast-enhanced scanning combined with ultrasound-guided liver biopsy for the diagnosis of hepatic space-occupying lesions can reduce the patient′s bleeding risk and improve the diagnostic accuracy.
