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.
