All physicians joined Unity Radiology. Each practice radiology at InnerVision Advanced Medical Imaging Center.

When you have an imaging exam performed at InnerVision Advanced Medical Imaging Center, your study will be interpreted by one of our board-certified radiologists. A radiologist is a physician with special training in diagnostic imaging such as MRI, CT, Ultrasound, Nuclear Medicine, Mammography and X-ray interpretation. Because radiologists use a wide variety of imaging tools to help your physician find out what is wrong with you, they are often called your doctor's doctor. To learn more about radiologists visit the web site of the American College of Radiology.

Imaging Philosophy:

The radiologists of InnerVision Advanced Medical Imaging Center are committed to producing the highest quality images and using these images to provide physicians and patients with the maximal amount of diagnostic information. Our radiologist are committed to remaining at the cutting edge of the uses of multiple imaging modalities and the interpretation of the images produced. 

Our goal is to optimize the cost-effective use of these technologies by applying them appropriately, and providing our customers with useful information that optimizes clinical decision-making.  Since our goal is to be part of the care-giving team, we encourage physicians and other health care providers to utilize us in a consultative pattern rather than in purely a referral pattern.  We never lose sight of the fact that what we are seeing is not just images, but people.
