BACKGROUND
The aim of this prospective study was the evaluation of preoperative three-dimensional ultrasound in detecting meniscal lesions compared to preoperative MRI.
METHODS
A total of 34 patients with clinical signs of meniscal lesions were examined preoperatively (11.7 MHz linear transducer) using the 3-D technique. Before ultrasound, MRI was performed, the results of which were unknown to the ultrasound examiner. The basis of the MRI result was the radiologist's written report. Arthroscopically the meniscal situation was noted and taken as reference.
RESULTS
At arthroscopy there were 10 lateral meniscal lesions at different locations and 47 medial meniscal lesions at different locations. The sensitivity (0.5-0.78) and specificity (0.75-0.95) of both imaging methods were overall comparable.
CONCLUSION
Ultrasound with the three-dimensional technique and high-resolution transducer in the hands of an experienced operator gives results comparable to the MRI interpretation by a general radiologist in detecting meniscal lesions.
背景
本前瞻性研究的目的是评估术前三维超声与术前MRI在检测半月板损伤方面的效果。
方法
共有34例有半月板损伤临床症状的患者在术前使用三维技术（11.7MHz线性探头）进行检查。在超声检查前进行了MRI检查，超声检查者不知道MRI的结果。MRI结果以放射科医生的书面报告为依据。通过关节镜观察半月板情况并作为参考。
结果
关节镜检查发现外侧半月板不同部位有10处损伤，内侧半月板不同部位有47处损伤。两种成像方法的敏感性（0.5 - 0.78）和特异性（0.75 - 0.95）总体相当。
结论
在经验丰富的操作者手中，使用三维技术和高分辨率探头的超声在检测半月板损伤方面的结果与普通放射科医生对MRI的解读相当。
