Body Imaging

Overview

Quantitative MRI is employed to detect, localize and grade tumors within the abdomen and pelvis. Prostate cancer imaging is a specific focus, where non-invasive imaging techniques allow physicians to identify tumor biomarkers. In collaboration with the UC San Diego Department of Urology, the Oncologic Imaging team offers prostate cancer imaging that can detect tumors and guide prostate biopsies.

Tumor Biopsy

The tumor is drawn in blue on anatomic imaging overlaid with A) perfusion data and B) RSI-MRI data. The H&E stained histology after prostatectomy D) shows the true boundary of the tumor outline in blue. A 3-D rendering C) of the whole prostate (green) and the tumor (yellow) shows the spatial position of the tumor within the prostate. RSI-MRI identified a suspicious area which after biopsy and prostatectomy was proven to be high grade tumor. As shown, the tumor is barely visible in conventional imaging.

RSI-MRI imaging showing biopsy proven high-grade cancer with extension into the right seminal vesicle (arrow)

Cancer Biopsy

There is also a region of enhanced RSI signal in the right pubic bone showing a likely focus of metastatic cancer. The extension into the right seminal vesicle and likely metastatic bone disease has implications for subsequent treatment.
