Synopsis

Keywords: Urogenital, Kidney

Motivation: In renal tumors, it is often difficult to differentiate between benign and malignant tumors, which could reduce unnecessary biopsies and surgeries.

Goal(s): To differentiate between angiomyolipoma (AML) and renal cell carcinoma (RCC).

Approach: Imaging with two types of diffusion-weighted images (DWI) with different Echo times (TE) and comparing T2 signals in AML and RCC at DWI (b=0) and DWI (b=1200).

Results: T2 signals at high diffusion restriction DWI (b=1200) were significantly lower in AML compared to RCC.

Impact: There is potential to preoperatively differentiate AML non-invasively, which previously due to the difficulty in differentiation, led to invasive diagnostic methods such as biopsies and unnecessary surgeries.
