摘要:目的比较DWI与T 2WI诊断子宫内膜癌敏感性以及测量病变大小准确性的差别,以更好地指导临床医师阅读MRI。方法34例子宫内膜癌患者术前均已行多模态3.0T MRI检查,以术后病理为金标准,比较这两种序列诊断EC的灵敏度,同时分别比较两种序列测量癌灶上下径、左右径与术后径线的差别。结果DWI诊断子宫内膜癌的敏感性(97%)高于T 2WI(80%),DWI所测得癌灶上下径、左右径与术后均有差别(P上下径=0.002,P左右径=0.002),T 2WI均无差别(P上下径=0.579,P左右径=0.261)。结论DWI可明显提高MRI诊断子宫内膜癌的敏感性,而T 2WI测量癌灶大小的准确性更高。
