From: Low-dose GBCA administration for brain tumour dynamic contrast enhanced MRI: a feasibility study
Comparison of fit error and derived kinetic parameters from different skull base tumours. Representative imaging from a patient with bilateral NF2-related VSs (A), and a patient with chondrosarcoma involving the anterior cranial fossa (B) shown. From left to right: T1W post contrast; parametric ve map; parametric Ktrans map; parametric vp map; and map of scaled fitting error (SFE). Kinetic maps and maps of SFE derived using either the low GBCA dose LEGATOSLDHS method or the full GBCA dose LEGATOSDICE method are shown for each patient. Note the more heterogenous enhancement of the skull base chondrosarcoma (*) relative to the VSs, and the much larger difference in SFE within the chondrosarcoma tumour region between the low-dose and full-dose acquisition.
