| Purpose: This prospective study was to compare the image quality and diagnostic
performance of breast cystic masses by conventional and advanced ultrasound (US)
techniques including tissue harmonic, compound, and the combination of these techniques.
Materials and Methods: All 91 patients, collectively having 109 breast cystic masses
were scanned using four US techniques (complicated cysts in 36, septated cysts in
33, and complex cysts in 40). Two breast radiologists independently assessed the
image quality and possibility of malignancy. Image quality was evaluated in terms of
contrast and clarity of the wall and internal echo pattern and then graded on a scale of
1 (poor) to grade 3 (satisfactory). The possibility of malignancy was graded on a scale
of 1 (suggestive of benignancy) to 5 (suggestive of malignancy) using US images.
The histopathological results and follow-up images were used as the reference standard
for the assessment of diagnostic performance. Results were evaluated by
Friedman’s test and receiver operating characteristic (ROC) analyses.
Results: In terms of image quality, a grade of 3 was significantly more frequent in
the three advanced US techniques than conventional US (p < 0.05). For assessment
of diagnostic performance, areas under the ROC curves in three advanced techniques
were significantly higher than in conventional US (p < 0.05).
Conclusion: Advanced US techniques including compound and tissue harmonic
US techniques provide a better image quality in breast cystic masses and also
improve the diagnostic performance compared with conventional US. |
