High-intensity focused ultrasound could allow prostate cancer patients to avoid surgery

The less invasive method could help men avoid some of the unpleasant side effects such as urinary incontinence and sexual dysfunction, which are known deterrents for patients facing potential prostatectomy.

Simulated MR images could eliminate the need for contrast in prostate scans.

Could synthetic images replace the need for contrast?

Synthetic images are often of diagnostic quality and can be reliably used to assess clinically significant prostate cancer while also sparing patients from contrast exposure.
