Description

This ExamCard is set to minimize the distortions in fMRI scans in areas like the temporal lobe. It combines a 3D acquisition, with high spatial resolution, fast readout and a large SENSE factor (in two directions) to reduce the distortions and obtain a robust fMRI signal. A dynamic scan-time of 3.6 seconds is obtained for 32 slices of 1.5 mm.

 

3D-fMRI

A multi-shot 3D FFE sequence is run with a TE of 28 ms. The TR is set to 100 ms combined with a low flip-angle of 25 degrees. Thirty-two slices are scanned with a slice thickness of 1.5 mm.

 

Within the ExamCard, for all scans, text and images are provided. Within the fMRI protocol the fMRI paradigms and IViewBold analysis are further described.
