Table 1.
Overview of representative DT studies. Major results are presented. AUC value was not mentioned in the literature unless described. Digital tomosynthesis: DT; tomosynthesis with metal artifact reduction: TMAR; computed tomography: CT; total hip arthroplasty: THA; anterior cruciate ligament: ACL; interclass correlation coefficient: ICC.
