Design outcomes

Primary

Measure	Time frame
The relationship between FDG-PET/CT diagnosis and qualitative evaluation of DWIBS. The sensitivity, specificity, and positive/negative predictive value of DWIBS were determined for each of the four grades: grade 0 or higher, grade 1 or higher, grade 2 or higher, and grade 3 or higher.	—
