T1-perfusion MRI derived relative cerebral blood volume (rCBV) is a key bio-marker for pre-surgical grading of gliomas; however, acquiring clinically relevant higher resolution T1-perfusion data with whole brain coverage is challenging due to possible loss in temporal resolution. This study takes the advantage of combining compressed-sensing with SENSE parallel-imaging i.e., Compressed-SENSE (CSENSE), to develop high-resolution whole brain T1-perfusion with improved temporality. The CSENSE enabled T1-perfusion derived rCBV values successfully differentiated high and low grade gliomas and matched with the histopathological grading. The rCBV cut-off value from CSENSE assisted T1-perfusion was similar to the routine T1-perfusion without-CSENSE of histopathology-matched gliomas.
