Schematic diagram of ADC parameters measurement. a ~ b ADC parameters measurement for occult IF; a An occult IF in the left sacrum (red arrow), which showed contrast enhancement on axial T1-weighted image post-contrast; b ADC parameters were measured on ADC map. c ~ d ADC parameters measurement for bone metastasis; c Bone metastasis in left femoral head (white arrow), which showed contrast enhancement on axial T1-weighted image post-contrast; d ADC parameters were measured on ADC map. The detailed approaches of ADC values measurement were as follows: at first ADC values of the lesion were measured manually drawing a region of interest (ROI) within contrast enhanced solid portion; the ADCmean, ADCmin, ADCmax and ADCstd were documented, respectively. Then, the ROI was copied to adjacent normal bone marrow and muscle, and documented the mean ADC, respectively
