RadNet Acquires the Valley Imaging Centers in Victorville, California

• RadNet acquires three multi-modality facilities in Victorville, California

• The acquisition strengthens RadNet’s presence in this market, a market where RadNet already has one facility

• Approximately 80 miles northeast of Los Angeles, Victorville is one of the fastest growing areas of San Bernardino County

LOS ANGELES, California, September 5, 2007 – RadNet, Inc. (NASDAQ: RDNT), a national leader in providing high-quality, cost-effective diagnostic imaging services through a network of owned and operated outpatient imaging centers, today reported that it acquired three multimodality imaging centers in Victorville, California for $3.3 million plus the assumption of approximately $1.2 million of debt.

The centers, previously owned by Valley Imaging Center, Inc., will substantially increase RadNet’s presence in a market where, prior to the acquisition, RadNet had a single-modality open MRI location which it acquired as part of its acquisition of Radiologix.  Victorville is one of the fastest growing areas of San Bernardino County.  Since 2000, Victorville’s population has grown nearly 50% to almost 100,000 people.  The acquisition has made RadNet the only significant multi-modality freestanding outpatient imaging provider in Victorville.

With approximately $6 million of annual revenues, Valley Imaging has been a leading provider of outpatient diagnostic imaging in Victorville for over 20 years.  The acquired centers offer a combination of MRI, CT, X-ray, Mammography, Fluoroscopy and Ultrasound.  The physician who has provided the interpretive radiology services to these three locations has joined Beverly Radiology Medical Group, the professional radiology group affiliated with RadNet in California.

“The Inland Empire in Southern California is a fast growing area and represents a significant growth opportunity for our company.  We have numerous relationships in this region, and our increased scale in the Victorville community will allow us to better serve the local referring physician community and large medical groups which are growing with the area.  This acquisition is consistent with our strategy of being the largest outpatient player in our operating markets. Geographic concentration and scale allow us to operate more efficiently, contract more effectively with payors and better serve our patients’ needs.” said Dr. Howard Berger, President and Chief Executive Officer of RadNet.
