PURPOSE

To evaluate the detection rate of breast cancer using Digital Tomosynthesis as an additional tool combined with digital mammography in ACR density patterns 2, 3 and 4 in a clinical setting.

METHOD AND MATERIALS

Retrospective study. From December 2010 to December 2011, a total number of 5718 Combo studies (2D-Digital mammography plus Tomosynthesis) were performed at our institution. 5603 cases were found to have ACR density patterns 2, 3 and 4. We evaluated the additional cancers detected on Tomosynthesis in these three density groups. Statistical analysis was performed calculating the Pearson Chi-square test and using the SPSS software.

RESULTS

133 breast tumours were detected on conventional digital mammography (detection rate 1.5 %). Forty seven additional cancers were detected on Tomosynthesis and not seen on standard mammograms: 9 cases on ACR 2 (the detection rate was increased 0.65 %), 20 cases in ACR 3 (0.92 %) and 18 cases in ACR 4 (0.87 %). No statistical differences were found in the detection rate among the three patterns (p=0.66). Tomosynthesis increased the detection rate 0.83 %, so the total detection rate using the combo studies was 2.33 %.

CONCLUSION

The addition of Digital Tomosynthesis increases the detection rate from 1.5 % to 2.33 %. There are not significant differences among the three ACR density patterns, so Digital Tomosynthesis can be useful not only in dense patterns but also in pattern 2.

CLINICAL RELEVANCE/APPLICATION

Our results show that additional Tomosynthesis increases the detection rate by 0.83% and there are not significant differences among the three ACR density patterns 2, 3 and 4.
