RadNet Inc. said Thursday that it has agreed to acquire Rochester-based Borg Imaging Group for $12 million in cash. The deal also includes about $1 million in debt.

Los Angeles-based RadNet, which operates freestanding medical diagnostic centers, said in a statement that it would finance the acquisition with available cash funds and from an existing $45 million revolving credit facility. The acquisition is scheduled to be final in June.

Borg owns and operates six facilities in Rochester and did about $14 million in annual revenue in 2006.

RadNet shares were flat in afternoon trading on the Nasdaq Thursday at $6.55.
