Table 4 Correlation between ABUS results and pathology

From: Does automated breast ultrasound (ABUS) add to breast tomosynthesis (DBT) in assessment of lesions in dense breasts?

ABUS Pathology
Benign Malignant
Benign 52 0
Malignant 1 29
Total 53 29
  1. True positive, 29/29 = 100% (cases diagnosed malignant by both ABUS and pathology)
  2. False positive, 1/53 = 1.9% (cases diagnosed as malignant by ABUS yet proved benign on pathology)
  3. True negative, 52/53=98.1% (cases proven negative by both ABUS and pathology)
  4. False negative, 0/29 = 0% (cases diagnosed as benign by ABUS yet proved malignant on pathology)
