However, maximal benefit is not always achieved due to difficulties of imaging at higher fields, such as T1 lengthening, T2/T2* shortening, specific absorption rate limitations, and field focusing. Multiple imaging strategies can be used to counter these problems. With appropriate attention to methodology, improved performance can be expected in traditional anatomical imaging, as well as areas such as functional magnetic resonance imaging (MRI), angiography, MR spectroscopy, and cardiac MRI.Thursday, 20 Jan 2005 16:36:49 GMT
