| 目的 探讨彩色多普勒超声及超声造影诊断脾梗死的价值。方法 58例脾梗死患者接受彩色多普勒超声检查,其中8例接受超声造影检查,分析其彩色多普勒及超声造影表现。结果 二维超声可见39例脾梗死患者表现为脾脏增大,脾实质内单发或多发楔形低回声区,11例表现为脾脏增大,周边单发或多发类圆形或不规则型低回声区,7例表现为脾脏内单发或多发境界不清高回声不均区,1例仅表现为脾脏增大及脾实质整体回声不均。彩色多普勒示低回声区及高回声不均区内均未探及血流信号。超声造影可见脾内不规则或楔形的"充盈缺损"区。结论 超声造影及彩色多普勒超声对脾梗死的诊断具有重要价值。 |

| Objective To investigate the value of color Doppler flow imaging (CDFI) and contrast-enhanced ultrasound (CEUS) in diagnosis of splenic infarction. Methods CDFI appearances of 58 patients and CEUS of 8 patients were analyzed. Results The appearances of splenomegaly and single or multiple wedged hypoechoic area in the spleen were found in 39 patients. Splenomegaly and single or mutiple irregular or type circular hypoechoic area in the spleen were found in 11 patients, while single or multiple hyperechoic inhomogenous zone in the internal part were detected in 7 patients. One patint only showed appearance of splenomegaly with inhomogenous echo of splenic parenchyma. No blood-flow signals was found in the lesions. Irregular or wedged "enhancement-defect" area was detected in the spleen on CEUS. Conclusion CEUS and CDFI play important role in diagnosis of splenic infarction. |
