3D Silent Parameter Mapping enables robust, high-resolution quantitative parameter mapping in the head. Beside silent neuroimaging the method also demonstrates unique potential for MR-only RTP in terms of synthetic CT conversion and automated organ-at-risk (OAR) delineation.
Figure 1: 3D Silent Parameter Mapping starts with a low FA~1° PD measurement (left) followed by a magnetization prepared segmented ZTE acquisition (FA=3°) to encode T1 and T2 contrast weighted information (right).
Figure 3: 3D Silent Parameter Mapping (FOV=19.2cm, res=1.2mm, BW=±31.25kHz, 1.5 averages, 6min05sec) at 1.5T showing PD (left), T1 (0…2s, middle) and T2 (0…1.6s,
right) parameter maps.
