June 5, 2008 – There was a 14 percent increase in MRI procedures from 2003 to 2007, for an average annual rate of 3 percent, representing a slowdown in procedure growth compared to the beginning of the decade, when the average annual growth rate from 1999 to 2003 was about 15 percent, according to IMV’s recent census of MRI sites in the U.S.
The census showed an estimated 27.5 million MRI procedures were performed at 7,195 sites in 2007, increasing from 24.2 million in 2003.
The census also found that early 1,100 hospitals are using mobile MRI services to provide their MRI capability. In 2007, the two highest volume categories were “spine” with 26 percent and “brain” with 25 percent of the MRI procedures and Magnetic Resonance Angiography (MRAs) comprise 9 percent of the total MRI procedure mix.
MRI breast imaging studies have doubled since 2003 from 314,000 to 645,000 procedures, but still account for only 2 percent of the total number of MRI procedures. Of the 2007 MRI procedures, 43 percent used a contrast agent as part of the imaging procedure.
IMV's 2007 MRI Market Summary Report describes trends in procedure utilization, the MRI installed base and purchase plans, workstations, contrast media utilization and budgets, power injectors and site operations characteristics. The report also covers adoption trends of new procedures such as echo planar imaging, MR spectroscopy, cardiac-approved MRI, functional MRI and multichannel MRI.
The data source for this report is IMV’s 2006/07 MRI Census Database, which provides comprehensive profiles of hospital and nonhospital MRI sites in the U.S. The database can be licensed by qualified subscribers and includes contact and site-specific information.
