Dean A. Tyrell, DO

　　　　　　　 I am a board certified (ABR) radiologist with fellowship training in body imaging from the Medical College of Virginia. I joined Progressive Physician Associates in July 2005 and help service the multiple hospitals affiliated with St. Luke's University Health Network. Currently I serve as Section Chief for Diagnostic Radiology. My practice encompasses nearly all facets of diagnostic imaging in both the inpatient and outpatient setting with focus on plain film, ultrasound, CT and MRI imaging. My clinical interest is liver MRI and utilizing this modality to work through diagnostic problems or indeterminate findings raised on other imaging studies. Given greater contrast resolution of MRI and specialized contrast agents we are often able to arrive at a specific diagnosis. This helps reduce further unnecessary testing,　alleviates patient's concerns or when appropriate directs them to appropriate　medical/surgical intervention in a timely fashion.
