Varied bone marrow perfusion function in some bone diseases has been identified by dynamic contrast enhancement (DCE) MRI. This pilot study explored a non-invasive and quantitative method, combining kinetic model and arterial spine labeling (ASL) technique, to study bone marrow perfusion at lumbar spine. A turbo field echo (TFE) acquisition with STAR labeling (STAR-TFE) was developed for better imaging compared to STAR-EPI. A kinetic model was applied on the ASL signal to provide a quantitative measure of perfusion function. The result shows that ASL combined with kinetic modeling is promising for quantitative study the perfusion in bone marrow.
