Musculoskeletal imaging at 3T: imaging and optimization

Cardiovascular Imaging at 3T

The challenges for cardiac MR imaging range in a magic triangle of spatial and temporal resolution, signal-to-noise ratio and the limitations induced by the need for breath-hold imaging. With the advent of multi-channel whole-body MRI systems at 3Tesla, these limitations can now be overcome. Parallel acquisition techniques (PAT) allow increasing temporal or spatial resolution at virtually no co...

Abdominal and Pelvic Imaging at 3T

3 Tesla magnets are no longer just a research tool used almost exclusively for brain imaging. Clinical 3T imaging of the abdomen and pelvis is now feasible and being performed worldwide. There is a huge push particularly from the industry to “upgrade” to 3T with units designed for whole body imaging. While in theory, 3T imaging offers higher signal to noise, increased spectral separation and im...

Hepatobiliary, pancreatic MR imaging progresses at 3T

Three-D gradient-echo sequences include LAVA (liver acquisition with volume acceleration, GE Healthcare), VIBE (volumetric interpolated breath hold examination, Siemens Medical Solutions), and THRIVE (T1 high resolution isotropic volume examination, Philips Medical Systems). Three-T MRI has been used clinically in Japan since 2005, and its features have been studied widely. Moving to 3T doubles...

Musculoskeletal MR Imaging at 3.0 Tesla

Introduction Most conventional MR imaging of the musculoskeletal system is done a 1.5 Tesla. Higher field systems, typically 3.0 Tesla, are now becoming available. 3.0T MRI means a higher signal-to-noise ratio (SNR), which can be used to improve imaging speed or resolution. However, there are changes in relaxation times at 3.0T as well as increased artifacts to consider. Our initial clinical ex...
