title: Clinical 3T MR imaging: mastering the challenges.
abstract: 3T MRI is ready to meet the needs of clinical practice. SAR limitations are minimized by technical advances and surface coils are available for all core applications. With appropriate adjustments to scanning protocols, one can master the challenges of scanning at 3T; studies of the brain, spine, chest, abdomen, pelvis, vasculature, and extremities can be consistently higher in quality than are those obtained at 1.5T. The superior studies that are obtainable at 3T have great appeal to clinicians who are sophisticated about MR technology in areas, such as neurology, orthopedics, vascular surgery, and oncology,and encourage a shift in referrals toward practices that invest in higher field technology. The greater sensitivity to magnetic susceptibility offers unique benefits in functional neuroimaging, and available software/hardware packages enhance clinical setting feasibility, which adds a source of new referrals. The greater overall signal of 3T can be manipulated to make scanning more comfortable and with less motion artifact because scan times could be half as long. Spectacular anatomic delineation that is provided by high-definition scanning at true 1024 resolution can improve preoperative assessment and may improve sensitivity to smaller lesions. 3T provides practices with an advantage that is sought increasingly by high field strength purchasers in a competitive market. Only cost considerations stand in the way of the eventual domination of 3T systems in the high field strength market.
