Computed tomography (CT) and magnetic resonance (MR) imaging are extremely useful in the accurate diagnosis of anterior knee pain, a common complaint arising from numerous causes (including fracture, chondromalacia patellae, and alignment and tracking abnormalities). Plain CT is effective for evaluating intraosseous lesions of the knee. Although CT arthrography provides excellent visualization of the patellar articular cartilage, the technique is expensive and invasive. Cine CT is an excellent method for assessing patellofemoral tracking and alignment. Kinematic MR imaging can also perform this function. In addition, MR imaging can provide valuable information concerning the status of patellar cartilage. Although MR imaging can accurately show high-grade chondromalacia patellae, it is less accurate in the detection of low-grade disease. The authors believe that MR imaging and plain radiography offer radiologists the greatest latitude in making a specific diagnosis of the cause of anterior knee pain; however, CT is a useful alternative.
计算机断层扫描（CT）和磁共振成像（MR）在准确诊断膝前疼痛方面极为有用，膝前疼痛是一种由多种原因（包括骨折、髌骨软化症以及对线和轨迹异常）引起的常见病症。普通CT对评估膝关节的骨内病变有效。尽管CT关节造影能很好地显示髌骨关节软骨，但该技术昂贵且具有侵入性。动态CT是评估髌股关节轨迹和对线的极佳方法。动态磁共振成像也能执行此功能。此外，磁共振成像可以提供有关髌骨软骨状况的有价值信息。尽管磁共振成像可以准确显示高级别髌骨软化症，但在检测低级别疾病方面准确性较低。作者认为，磁共振成像和普通X线摄影为放射科医生对膝前疼痛原因做出特定诊断提供了最大的灵活性；然而，CT也是一种有用的替代方法。
