According to IMV’s recent census of MRI sites in the US, an estimated 27.5 million MRI procedures were performed at 7,195 sites in 2007. This represents a 14 per cent increase from 24.2 million in 2003, for an average annualized rate of three per cent per year. This represents a slowdown in procedure growth compared to the beginning of the decade, when the average annual growth rate from 1999 to 2003 was approximately 15 per cent per year.
“Several factors are contributing to the slower growth of MRI procedures, which in turn influences MRI purchases. With the advent of the Deficit Reduction Act (DRA) of 2005, related legislation against physician self-referral and the relative maturity of the MRI market, MRI purchases have slowed,” observed Lorna Young, Senior Director, Market Research at IMV. “Currently, virtually all of the hospitals above 200 beds have at least one MRI, and the DRA has slowed the acquisition of MRI systems by independent imaging centers. Unlike CT, which is used 24x7 for emergency and scheduled procedures, MRI procedures tend to be provided on a scheduled basis for specifically prescribed indications. We have also observed that the replacement cycle for MRI is getting longer, which is slowing the number of MRIs that are replaced.”
“New procedures are the key avenue for growth, and 3T MRIs are providing some of the market excitement for the future. While only three per cent of the units installed in 2003 were 3T, at least 20 per cent of those who are planning to purchase MRI over the next few years are planning to purchase these systems as replacement or additional units for their department.”
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 multi-channel MRI. Highlights include:
- Nearly 1,100 hospitals are using mobile MRI services to provide their MRI capability.
- In 2007, the two highest volume categories were 'spine' with 26 per cent and 'brain' with 25 per cent of the MRI procedures.
- MRI breast imaging studies have doubled since 2003 from 314,000 to 645,000 procedures, but still account for only two per cent of the total number of MRI procedures.
- Of the 2007 MRI procedures, 43 per cent used a contrast agent as part of the imaging procedure.
