HMCA is a physician and diagnostic services management company specializing in the management of MRI scanning centers, including stand-up MRI facilities. As a result of its unique ability to scan patients in weight-bearing positions the stand-up MRI has detected problems that would have gone undetected on ordinary lie-down scanners. The stand-up is the only true open MRI. Patients typically sit and watch a big screen TV throughout their scans. Problems with claustrophobia are gone.
