Radiologists are an essential part of the diagnosis and treatment of men with prostate cancer. Radiologists use advanced medical imaging technologies, such as perfusion dynamic magnetic resonance imaging (MRI) to diagnose the location and extent of prostate cancers. This information allows our team of urology experts to provide state of the art treatment options specifically tailored for each patient. At the Prostate Cancer Institute of LA, our radiologists are the leaders in their field and have decades of experience, ensuring that our patients receive the best care available.
