目的探讨膈褶检出率及其超声表现。方法连续选取腹部超声受检者361例,分析肝内出现膈褶者的临床资料和超声表现。结果 361例中共检出膈褶29例,检出率为8.0%,单发者23例,多发者6例,均位于近肝右叶的膈面,由前向后斜行。长轴切面表现为明暗相间的多层条带状结构15例,回声均匀但粗细不均的高回声5例,紧贴膈肌的线状带3例;短轴切面显示为类圆形、帆状或线状中高回声。6例多发膈褶表现为长短不一、沿膈肌分布的中高回声,间距为1~2cm。结论正确认识膈褶的超声图像表现,可以减少肝脏疾病的误诊,对临床有参考价值。
Objective To investigate the detection rate of diaphragmatic pleura and its ultrasound findings. Methods A total of 361 cases of abdominal ultrasonography were selected. The clinical data and sonographic findings of diaphragm pleated patients were analyzed. Results Totally 291 cases of diaphragm were detected in 361 cases, the detection rate was 8.0%, 23 cases were single and 6 cases were multiple. All of them were located in the diaphragmatic surface of the right lobe of the proximal liver. The long-axis section showed a multi-tiered strip-like structure with 15 cases of echogenicity, 5 cases of echoes with uneven echoes and 3 cases of linear bands closely attached to the diaphragm. The short axis showed a round, saillike Or linear echo in the high. Six cases of multiple pleuroplasty manifested in varying lengths, along the diaphragmatic distribution of high echo, the spacing of 1 ~ 2cm. Conclusion Correct understanding of the phrenic pleura in the performance of ultrasound images can reduce the misdiagnosis of liver disease, a reference value for clinical.
