The usefulness of b value threshold map in the evaluation of rectal adenocarcinoma

ConclusionBoth ADC andbThreshold values can differentiate between degrees of pathologic differentiation and T1-2 versus T3-4. Potential added advantages however of thebThreshold map include a higher CNR compared with DWI images, thereby improving lesion visualization detection, and better diagnostic performance for end staging than ADC. Thus, thebThreshold map may compliment DWI and ADC to evaluate pathologic features of rectal primary tumors and metastatic lymph nodes.
