This is a comprehensive Release 5.4 ExamCard for wrist imaging on Ingenia 1.5T.
Compressed SENSE is used in all sequences, reducing the scan time while maintaining virtually equal image quality compared to scans without Compressed SENSE.
Some 3D sequences have been added, which have a in-plane resolution that is comparable to 2D, but much thinner slices.
As Compressed SENSE now allows to achieve shorter scan times for these 3D sequences with thinner slices, these become attrative to potentially replace the 2D sequences, providing more confidence for making a diagnosis thanks to the higher spatial resolution.
