Poster Information
Abstract: Multiparametric prostate MRI (mpMRI) has very rapidly evolved as the first line imaging investigation for patients with suspected prostate cancer. Further to data from the multi-centre UK PROMIS trial, mpMRI is widely performed prior to prostate biopsy. This has led to a paradigm shift in prostate cancer diagnostics and a surge in demand for mpMRI nationally. It is inevitable that with the increased volume of imaging, there is a high likelihood of detecting other incidental findings which may heavily influence clinical management.

We illustrate a range of detected incidental findings (IF) on the various prostate MRI sequences which include detection of caecal cancer, transitional cell carcinoma of the bladder, rectal cancer, cystic and solid malignant renal lesions, renal vein invasion secondary to renal cell carcinoma, suprarenal masses, retroperitoneal nodal mass secondary to lymphoma, hydroureteronephrosis secondary to obstructing ureteric calculi, gallbladder disease, benign liver lesions and cystic pancreatic lesions. For important findings, we will demonstrate further imaging studies performed to further evaluate the detected abnormality. The prostate protocol used in this centre includes a quick breath-hold sequence of the abdomen primarily to assess para aortic nodes.

With increasing prostate mpMRI services nationally, these illustrated cases highlight the importance of a systematic abdominopelvic review approach for reporting prostate MRI and the added value of limited upper abdominal sequences which generally require minimal time to acquire. By detecting other co-existing pathology, clinical management for patients with suspected prostate cancer can be significantly influenced. Without our routine use of upper abdominal sequences in particular, some of these cases would otherwise have proceeded to clinically inappropriate radical prostate cancer treatment.
