摘要
目的:探讨先天性支气管肺囊肿在多层螺旋CT的支气管肺表面重建(SSD)、多平面重建(MPR)的表现。方法:8例先天性支气管肺囊肿均用多层螺旋CT(4i)进行薄层扫描。测量囊肿的大小和CT值,并将原始图像在工作站上进行支气管和肺SSD和MPR。结果:8例先天性支气管肺囊肿中单发7例,多发1例;右肺6例,左肺2例;含气囊肿3例,含液囊肿2例,含气液混合囊肿3例。囊肿最大12.4cm×10.1cm×9.2cm,最小1cm×1cm×1cm;CT值最低-1008Hu,最高80.5Hu。3例含气囊肿用支气管和肺SSD能很好显示;2例含液囊肿用MPR法能良好地显示;3例含气液混合囊肿用支气管和肺SSD和MPR两种方法都能很好显示。结论:多层螺旋CT扫描以及支气管和肺SSD、MPR等后处理技术是先天性支气管肺囊肿很实用的检查方法。
Objective: To study the appearances of multislice spiral CT(MSCT) with surface shaded display(SSD) and multiplanar reconstruction(MPR) in different types of congenital bronchopneumonic cysts. Methods: MSCT thin-slice scanning were performed in 8 cases. The size and CT value of each bronchopneumonic cyst was measured. SSD and MPR reconstruction were performed on the workstation. Results: The lesion was found to be isolated in 7 cases and multiple in 1 case. The lesion was on the right side in 6 cases, on the left side in 2 cases. Air was manifested in the cyst in 3 cases, liquid in 2 cases, and a mixture of gas and liquid in 3 cases. The size of the biggest cyst was 12.4cm×10.1cm×9.2cm and the size of the smallest cyst was 1cm×1cm×1cm. The CT value of the cysts ranged from -1008Hu to 80.5Hu. The cyst with gas in 3 cases could be clearly manifested by SSD, the cyst with liquid in 2 cases could be clearly found by MPR, and the cyst with mixture of gas and liquid in 3 cases could be well displayed in both SSD and MPR images. Conclusions:The examination of MSCT with SSD and MPR reconstruction is the first choice of examination for congenital bronchopneumonic cyst.
