超声造影与增强CT在诊断胰腺占位性病变的对比分析

Comparative Analysis of Ultrasound Contrast and Enhanced CT in the Diagnosis of Pancreatic Lesions

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.
