ABSTRACT
Objective To explore the value of dual energy CT displaying knee joint torn posterior cruciate ligament (PCL). Methods Ten cases with single knee joint torn PCL were scanned by 1.5 TMR and dual energy CT. By the use of postprocessing technique of muhiplanar reformation (MPR) and volume rendering technique (VRT), the CT value,length,thickness of PCL were assessed by paired t test respectively. Results MPR and VRT clearly displayed the PCL. The CT value of the patient sides and normal sides were(60.10±3.21), (72.98±7.35) HU(t=4.33,P=0.006), the length were(4.42±0.56),(4.14±0.49) cm (t=-1.20,P=0.285), the thickness of the attachment site and middle sire were (0.88±0.19), (0.58±0.10), (0.38±0.12) cm and (0.43±0.07), (0.39±0.03), (0.43±0.12) cm (t=-6.89,P=0.001;t=-4.38,P=0.007;t=0.85,P=0.587) respectively. Conclusion Dual energy CT can demonstrate clearly the ligament with three-dimension display,and may provide important information for diagnosis and per-surgical evaluation.
