CONTROVERSIES IN IMAGING
High Field Cardiac MRI
-
A Case for Ultrahigh Field Cardiac Magnetic Resonance
For a new technology, high-field cardiac magnetic resonance (CMR; 3.0 T≤B
0
≤7.0 T) has come a long way. Not only has the number of reports referencing clinical applications risen,
1,2
but prices for 3.0T systems have dropped almost 50% since the beginning of the millennium, and operational and service costs are virtually identical to those of 1.5T machines. New 3.0T installations make up about 25% of the total market share and are increasing at an annual growth rate of ≈10%.
Low Field Cardiac MRI - A Compelling Case for Cardiac Magnetic Resonance's Future
Cardiac magnetic resonance (CMR) is arguably unmatched in its ability to evaluate cardiovascular structure and function, to characterize myocardial tissue by a wide variety of mechanisms, and to quantitatively assess blood flow and perfusion without the use of radiation or the need for invasive catheterization. CMR research and development continues at a rapid pace both in academia and by commercial vendors, and every year, new techniques are put forth that improve on existing applications and provide new capabilities that further expand the clinical utility of this powerful modality.
