Descripción
Inclusion Criteria:
- patients who have been referred to a breast ultrasound because of a positive physical palpation and/or positive mammograms and/or positive ultrasound and/or positive MRI.
- female
- age 21 or older
- provide informed consent
Exclusion Criteria:
- Women who are unwilling or unable to provide informed consent
- Women with breast implants
- Women with superficial lesions or lesions on skin (with the most superficial surface of the lesion within 5 mm of the skin surface)
- Women who are pregnant or breastfeeding
- Women who are undergoing chemotherapy or radiotherapy for any cancer
- Women with previous breast conserving surgery on the breast of interest Note: Previous excision of a benign lesion 4 cm or more away from the suspected lesion does not constitute an exclusion criterion.

Estimates of Effect of Selectively Upgrading BIRADS Category 3 and Downgrading BIRADS 4a Masses Based on SWE Features. Overall Specificity and Sensitivity of BI-RADS Score Using Conventional B-mode Ultrasound vs. B-mode + Certain SWE Characteristics
Periodo de tiempo: 2 years
|
Positive reference standard = malignant cytologic or histopathologic result. Negative reference standard = BIRADS 2 lesions, BIRADS 3 lesions with benign histopathology, or a 1 year follow-up ultrasound exam showing resolved or decreased lesion size. Conservative strategy:features of E-homogeneity, E-max and E-color were used to upgrade BIRADS 3 lesions to BIRADS 4a' or downgrade BIRADS 4a lesions to BIRADS 3'. Aggressive strategy used the same features but upgraded and downgraded more lesions. Based on 939 lesions. |

Qualitative Intraobserver Reproducibility of SWE Related to Homogeneity Feature
Periodo de tiempo: performed on the same day, within 2 years from study start date
|
614 benign and 144 malignant breast lesions were scanned in SWE 3 consecutive times, and the similarity of the 3 images was evaluated by the investigator.
|
performed on the same day, within 2 years from study start date
|
|
Intraobserver Reliability of Quantitative SWE Measurements
Periodo de tiempo: performed on the same day, within 2 years from study start date
|
614 benign and 144 malignant lesions.
Each category's measurement (diameter, area, etc..) is performed 3 times.
These 3 measurements are then compared with each other in order to calculate the interclass correlation coefficient.

Interobserver Agreement of B Mode Ultrasound and SWE Features
Periodo de tiempo: performed on the same day, after study completion
|
614 benign and 144 malignant breast masses.
