Role of Diffusion-Weighted Magnetic Resonance Imaging (DWMRI) in Assessment of Primary Penile Tumor Characteristics and Its Correlations With Inguinal Lymph Node Metastasis: A Prospective Study

Penile cancer is a rare malignancy. The extent of lymph node (LN) metastasis is the most important prognostic factor in penile cancer. However, preoperative prediction of LN involvement in clinically non-palpable LN is still a challenge. In absence of a reliable biomarker, attempts are being made to validate imaging characteristics as a predictive tool. The aim of the present study is to assess the primary penile tumor characteristics with diffusion-weighted magnetic resonance imaging (DWMRI) and its correlations with inguinal LN status and tumor positivity in LN dissection specimen within normal sized LNs
