Bone marrow metastases are common manifestation of many malignant cancers. In order to gain deeper insight into patients state of disease and the treatment response, the bone marrow cellularity can be assessed by the histogram analysis and monitoring of the ADC-maps acquired by DW-MRI. However, correct decision making about the effectiveness of therapy is dependent on the ROIs selected from the ADC-maps, raising concerns about the susceptibility of manual ROI placement to human errors. In this work, an automatic bone marrow registration/segmentation histogram analysis approach was applied to the ADC-maps, to show its superiority over the manual ROI analysis method.
