Table 4.
Diagnosis of false negative cases and the number of readers that scored them as false negative. Experience level is indicated of the number of readers that missed the lesion on CESM. In addition, lesion characteristics such as diameter (given in millimetres), histologic grade, DCIS grade and hormonal receptor status (ER, PR, HER2NEU) are given. Hormone receptor status in case of pure DCIS is not evaluated and therefore not available (n/a) for these cases
