Results
A total of 22 women (aged: 29-76 years old) were enrolled in the current study; 24 lesions were examined and finally used for statistical analysis.
The benign lesions sizes determined on B-mode images ranged from 7.4 mm to 30.5 mm (mean: 13.5 mm),
while the malignancies sizes ranged from 3.8 mm to 24.8 mm (mean: 9.9 mm).
Breast nodules evaluated were predominantly localized in the upper-outer quadrant (11 lesions).
Histological findings showed 13 benign and 11 malignant lesions.
Figures 3-4 Among benign lesions,
there were 9 fibroadenomas,
2 intraductal papillomas,
a complicated cyst and a case of stromal fibrosis.
Among malignant lesions,
there were 6 invasive ductal carcinomas,
an invasive papillary carcinoma,
3 invasive lobular carcinomas and an apocrine carcinoma.
Color map results of two operators were similar (k>0.895); first operator reported 7 false positive (38.9%) and second radiologist 6 false positive (35.3%). Using strain ratio cut-off as a value of 3.2,
our results showed 4 false positive (26.7%) for both operators placing manually ROIs.
Using Assist Strain Ratio,
our results showed 4 false positives (28.6%) and a false negative (10.0%).
According to our experience,
using ASR acquisition time is sharply reduced,
allowing to acquire faster elastographic data in comparison manual strain ratio.
