摘要
目的对比分析超声造影与增强 CT对胰腺占位性病变的诊断价值。方法 选择我院收治的39例胰腺占位性病变患者 为研究对象,均进行超声造影与增强CT检 查,以手术病理检查为金标准,比较超声 造影与增强CT对胰腺占位性病变的诊断价 值。结果 本次39例胰腺占位性病变患者 均为单发病灶,其中32例恶性病变,7例 良性病变。超声造影检查诊断与手术病理 结果相符者,恶性病变27例,良性病变 5例;胰腺恶性病变超声造影始增时间、 始减时间和渡越时间均明显短于良性病 变和周围实质(P<0.05),峰值强度低于良 性病变和周围实质(P<0.05)。增强CT与手 术病理结果相符者,恶性病变27例,良 性病变4例。超声造影检出准确率82.05% 与增强CT检出准确率78.49%无显著差异 (P>0.05)。结论 超声造影与增强CT对胰 腺占位性病变诊断检出率相近,均有较高 临床诊断价值。
Objective To compare and analyze the diagnostic value of ultrasound contrast and enhanced CT in the diagnosis of pancreatic space-occupying lesions. Methods A total of 39 cases of patients with pancreatic lesions in our hospital were selected and were examined by ultrasound contrast and enhanced CT. Surgical pathology was taken as gold standard, and the diagnostic values of ultrasound contrast and enhanced CT were compared in the diagnosis of pancreatic lesions. Results All the 39 cases of patients with pancreatic lesions were single lesions, of which 32 cases were malignant and 7 cases were benign. The ultrasound contrast diagnosis of 27 malignant lesions and 5 benign lesions wewere consistent with the surgical pathology findings. The beginning enhancement time, beginning reduction time and transition time of ultrasound contrast in pancreatic malignant lesions were all significantly shorter than those in benign lesions and surrounding parenchyma (P<0.05), and the peak intensity was lower than that in benign lesions and surrounding parenchyma (P<0.05). There were 27 malignant lesions and 4 benign lesions among patients whose enhanced CT was consistent with the surgical pathology findings. There was no significant difference in the detection accuracy between ultrasound contrast and enhanced CT (82.05% vs 78.49%) (P>0.05). Conclusion Ultrasound contrast and enhanced CT have similar diagnostic detection rate and have high clinical diagnostic value in the treatment of pancreatic space-occupying lesions.

前言
胰腺癌为消化道恶性肿瘤,主要起源于胰管上皮导管腺癌,近年 来其发病率和致死率呈上升趋势,且预后差,5年生存率不足1%[1-2]。 胰腺癌临床诊断较为困难,早期确诊率低,如何提高胰腺癌诊断准确 率已成为临床研究重点。影像学检查中增强CT能较为清晰地显示肿瘤 血管浸润情况,相较于CT平扫对病变范围和肿瘤侵犯情况可更好反 映[3]。而超声造影可显示小血管内血流信号,反映病变血供情况[4]。本 次研究对超声造影与增强CT诊断胰腺占位性病变情况进行分析比较, 以期为临床胰腺癌诊断提供依据。具体报道如下。
