{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/6993/annotated_viewer_json?iframe=true\u0026lang=us"}
MR perfusion demonstrates increased blood volume in the regions of increased T2 consistent with the presence of tumor.
Case Discussion
Although perfusion is most frequently shown as color maps, ROIs and curves can also be helpful.
