To determine the diagnostic accuracy of CT arthrography and virtual arthroscopy in the diagnosis of anterior cruciate ligament and meniscus pathology.
Thirty-eight consecutive patients who underwent CT arthrography and arthroscopy of the knee were included in this study. The ages of the patients ranged from 19 to 52 years and all of the patients were male. Sagittal, coronal, transverse and oblique coronal multiplanar reconstruction images were reformatted from CT arthrography. Virtual arthroscopy was performed from 6 standard views using a volume rendering technique. Three radiologists analyzed the MPR images and two orthopedic surgeons analyzed the virtual arthroscopic images.
The sensitivity and specificity of CT arthrography for the diagnosis of anterior cruciate ligament abnormalities were 87.5%-100% and 93.3-96.7%, respectively, and those for meniscus abnormalities were 91.7%-100% and 98.1%, respectively. The sensitivity and specificity of virtual arthroscopy for the diagnosis of anterior cruciate ligament abnormalities were 87.5% and 83.3-90%, respectively, and those for meniscus abnormalities were 83.3%-87.5% and 96.1-98.1%, respectively.
CT arthrography and virtual arthroscopy showed good diagnostic accuracy for anterior cruciate ligament and meniscal abnormalities.
确定CT关节造影和虚拟关节镜检查在诊断前交叉韧带和半月板病变中的诊断准确性。
本研究纳入了38例连续接受膝关节CT关节造影和关节镜检查的患者。患者年龄在19至52岁之间，均为男性。从CT关节造影图像中重新格式化矢状面、冠状面、横断面和斜冠状面多平面重建图像。使用容积再现技术从6个标准视图进行虚拟关节镜检查。三位放射科医生分析多平面重建图像，两位骨科医生分析虚拟关节镜图像。
CT关节造影诊断前交叉韧带异常的敏感性和特异性分别为87.5%-100%和93.3%-96.7%，诊断半月板异常的敏感性和特异性分别为91.7%-100%和98.1%。虚拟关节镜检查诊断前交叉韧带异常的敏感性和特异性分别为87.5%和83.3%-90%，诊断半月板异常的敏感性和特异性分别为83.3%-87.5%和96.1%-98.1%。
CT关节造影和虚拟关节镜检查在前交叉韧带和半月板异常的诊断中显示出良好的诊断准确性。
