High tech prostate imaging, biopsy and treatment: UTMB now offering MRI-guided prostate evaluation and therapy

 UTMB is proud to introduce a complete MRI solution for analysis, planning, biopsy and possible non-surgical ablative treatment of prostate cancer. The advanced imaging capabilities and biopsy tools allow state-of-art imaging and intervention for men experiencing persistently elevated PSA (prostate specific antigen) levels suspicious for prostate cancer.

 This new paradigm for evaluating and treating men with prostate cancer is a cooperative effort of the UTMB radiology and urology departments. The diagnostic MRI requires no special preparation and no rectal instruments and is highly sensitive and specific for focal cancers in the prostate gland. The prostate biopsy, done at a different setting, involves MRI-guidance and tissue sampling of areas of the prostate gland considered suspicious by the previous diagnostic MRI.

While many men will require radiation or surgical treatment, some focal prostate cancers can be watched with follow up MRI’s and some can even be ablated using laser or freezing technology– both treatments which fortunately have a very low risk of causing impotence or urinary problems.

Patients interested in this technology can learn more by contacting Dr. Walser and Dr. Joseph Sonstein via http://radiology.utmb.edu/ir or by email to the urology department josonste@utmb.edu or radiology department emwalser@utmb.edu

About emwalser

Dr. Walser is an energetic leader with an outstanding track record as a clinical and translational investigator. He will play a vital role in ensuring that our imaging services continue to flourish. As an internationally renowned interventional radiologist, his clinical interests are wide-ranging and include the use of ablation therapy to treat small tumors of the liver and kidney as an alternative to traditional open surgery. For example, he developed a new program of laser ablation of tumors using magnetic resonance imaging (MRI) guidance. His investigational efforts focus on developing interventional procedures using MRI to treat and diagnose patients without the use of harmful ionizing radiation. Using MRI, ultrasound, and CT technology, Dr. Walser has developed advanced protocols and techniques to image cardiovascular disease non-invasively. Dr. Walser has published extensively in peer-reviewed journals including the Annals of Thoracic Surgery,Annals of Surgery, and Cardiovascular and Interventional Radiology, as well as book chapters, abstracts and letters. He is a reviewer for many prestigious journals and has lectured throughout the world regarding cancer treatment and minimally invasive surgical management. He is a member of several important professional organizations including the American Board of Radiology (examiner), American College of Radiology, American Roentgen Ray Society, and Radiological Society of North America. As an educator, Dr. Walser has been very active in teaching and has mentored numerous residents and fellows. Dr. Walser earned his medical degree from UTMB in 1988. He completed both his diagnostic radiology residency training (1992) and interventional radiology and body imaging fellowship training (1993) at the Indiana University Medical Center. He began his professional career as an Assistant Professor and Chief of Diagnosis in the Department of Radiology at UTMB. After leadership service at other institutions including the St. Paul Medical Center in Dallas and Mayo Clinic in Jacksonville, Dr. Walser returned to UTMB in 2011.
