Micro-ultrasound may be a suitable alternative to MRI for predicting pathological tumor volume in prostate cancer lesions, according to Swiss research published on 13 March in Urologic Oncology: Seminars and Original Investigations.
Dr. Arnas Rakauskas, a urologist and clinical fellow in robotic surgery from Lausanne University Hospital, and colleagues found that while micro-ultrasound can predict prostate volume more accurately than MRI, the latter can identify more tumors. However, both modalities tend to slightly underestimate pathological tumor and prostate volume.
“Our study shows that both micro-ultrasound and MRI can be useful in planning focal treatments or radical prostatectomy strategy,” the authors wrote. “However, the underestimation of real tumor size in imaging should always be considered when…
