Bicomponent Mapping of Cortical Bone Using a New Interleaved UTE Imaging Sequence. [PDF]

Magn Reson Med
ABSTRACT Purpose Ultrashort echo time (UTE) MRI enables direct imaging of cortical bone and quantification of its water compartments via bicomponent T2* modeling. However, conventional approaches require multiple separate dual‐echo scans due to limitations in gradient power. This approach is prone to inter‐scan inconsistencies such as motion and signal

Temperature Mapping During MR-Guided Cryoablation Using a FLORET UTE Sequence. [PDF]

Magn Reson Med
ABSTRACT Purpose To implement a three‐dimensional FLORET‐UTE sequence for rapid MR thermometry during cryoablation and to validate voxel‐wise temperature maps against fiber‐optic probes in ex vivo bovine liver. Methods A FLORET‐UTE trajectory (TE 50 μs, 1.6 mm isotropic, 18 s/volume) was executed on a 3 T scanner while dry‐ice cryoablation was applied ...
