To assess treatment response through quantitative analysis, in metastatic breast cancer patients, computer-aided segmentation of bone marrows is beneficial. We propose a semi-automatic segmentation method based on level-set and region growing techniques applied to T1-W images to facilitate extraction of apparent diffusion coefficient (ADC) features for the purpose of treatment response assessment from bone marrows of pelvic region. The results of applying the method on T1w/ADC-map of 10 patients shows a dice score of 81%, suggestive of high agreement of our proposed segmentation approach with expert’s opinion.
