[Recent progress in image diagnosis of female pelvis]

MRI has been employed most in the diagnosis of female pelvic lesions because of its excellent tissue contrast. The T 1-&T 2-weighted image is mainly used for the diagnosis, but very recently the diffusion weighted image has been introduced in clinical practice, with the advance of imaging methods. The diffusion weighted image has high sensitivity to malignancy, especially to dissemination and lymph node metastasis, but may have low specificity to differentiate malignant from benign lesions. Hence,despite the MRI advantage, the diagnosis has to be conducted based on both new and conventional images.
