Table 1a.

Sensitivity, Specificity, PPV and NPV in Diagnosing Malignant Disease (DCIS and Invasive Cancer) using an ultrasound Imaging Threshold Level of 4.6 a.u. in Prospective Imaging Trial in 63 Mammary Glands Analyzed by Two Independent Readers.

Ultrasound
Imaging
Threshold Level
(a.u.)		 Sensitivity (95% CI) Specificity (95% CI) PPV (95% CI) NPV (95% CI)
4.6 100 (91 – 100) 87 (66 – 97) 93 (81 - 99) 100 (83 - 100)

Note: Values are identical for both readers since both readers misdiagnosed the same number of cases (see Table 1b).
