摘 要: | 目的观察脾结核在超声造影及计算机断层扫描(CT)中的影像学表现,并探讨两种影像学方法在脾结核中的诊断价值。方法回顾性分析2009年1月-2014年3月我院门诊部收治的经手术病理证实26例脾结核患者的临床资料,对所有病例患者的超声造影及CT影像学表现进行分析比较,并对两种诊断方法的应用价值进行评估。结果脾结核患者经超声造影检查有低回声型、混合回声型及强回声型,超声造影表现基本相同,无增强型为其最常见超声造影表现;CT平扫脾脏内多发大小不等结节状稍低密度影,边缘不清,而CT增强扫描边缘及内部分隔明显不强化,与周围脾脏相较呈明显低密度影,类似囊性病灶征象及钙化灶征象是脾结核相对典型的表现,超声造影与CT对脾结核患者诊断准确率无显著差异(P0.05)。结论超声造影和CT对脾结核诊断均具有特异性,两种诊断方法均值得临床推广应用。

Value of Contrast-enhanced Ultrasound and CT in the Diagnosis of Splenic Tuberculosis |

Abstract: | Objective To observe the imaging findings of contrast-enhanced ultrasound and computed tomography (CT) in splenic tuberculosis, and explore the value of two imaging methods in the diagnosis of splenic tuberculosis. Methods From January 2009 to March 2014, the clinical data of 26 patients with splenic tuberculosis confirmed by surgery and pathology in outpatient department in our hospital were retrospectively analyzed. All imaging findings of contrast-enhanced ultrasound and CT were analyzed and compared, and the application value of the two diagnostic methods was evaluated. Results Contrast-enhanced ultrasound showed low echo type, mixed echo type and strong echo type, and the findings were basically the same, and without enhanced type was the most common finding of contrast-enhanced ultrasound. CT scan showed multiple different sizes of nodular slightly low density in spleen, and the boundaries were not clear, while the enhanced CT scan showed that boundaries and internal separation obviously were not enhanced, and compared with surrounding spleen, there was significantly low-density shadow, similar signs of cystic lesions and calcification were relatively typical manifestations of splenic tuberculosis. There was no significant difference in accurate rate between contrast-enhanced ultrasound and CT in the diagnosis of splenic tuberculosis (P>0.05). Conclusion Both of contrast-enhanced ultrasound and CT have specificity in the diagnosis of splenic tuberculosis, and are worthy of clinical application. |
