The knee examined were positioned neutrally rotated in a transmit-receive knee coil. Continues sagittal T1-weighted spin echo images (repetition time /echo time /slice thickness = 500-700ms / 15-17ms /5mm ) were obtained.

Examination

A series of 30 T1-weighted FLASH images (TR/TE/ flip angle/ slice thickness = 4- ms/ 12 ms/ 70 degree / 5 mm) each with an imaging time of 10 s was then performed in the same, preselected sagittal slice through the insertion of the posterior cruciate ligament on the femoral bone (dynamic imaging). Then, a series of 30 T1-weighted FLASH images were acquired after the injection of 0.05mmol Gd-DTPA per kilo of body weight. The FLASH sequence covered the enhancement during the first 285 seconds. Afterwards the T1-weighted spin-echo sequence was repeated. In all sequences, the size of imaging matrix was 192-256x256 and the field of view (FOV) was 180-200 mm.

Examination

The patient was examined in supine position with the hand along the side of the body. Following the Gd-DTPA injection (0.1mmol/kg of body weight), the dynamic sequence was performed resulting in 30 consecutive GRE images (TR/TE 60/6, FOV/imaging matrix 160×160mm/ 256×128) in three pre-positioned planes every 10sec. slice thickness 4mm in the coronal plane; Scanning time 300s.
