A role for elastography in the diagnosis of breast lesions by measuring the maximum fat lesion ratio (max-FLR) by tissue Doppler imaging.
Summary of "A role for elastography in the diagnosis of breast lesions by measuring the maximum fat lesion ratio (max-FLR) by tissue Doppler imaging."
BACKGROUND:
The role of elastography for breast tumors is still ambiguous. The purpose of this study was to inquire how effectively elastography can be used in the diagnosis of breast tumors.
METHODS:
The fat lesion ratio (FLR) of 244 lesions (99 malignant and 145 benign lesions) was calculated using tissue Doppler imaging with elastography. The pathological confirmations were performed by core needle or excisional biopsy. Conventional ultrasonography (US) findings were classified according to the Breast Imaging Reporting and Data System. We tried to set the region of interest (ROI) at the hardest area of the target and measured the maximum FLR (max-FLR) of the target with elastography, whereas the control ROI was placed in the subcutaneous adipose tissue. The diagnostic potential of the max-FLR combined with the US category was evaluated.
RESULTS:
The mean max-FLR of malignant lesions was significantly greater than that of benign lesions, at 11.0 and 4.4, respectively (p < 0.01). The max-FLR showed a wide overlap range between benign and malignant lesions, but there were no malignant lesions showing a less than 2.0 max-FLR. Ninety-six percent of the lesions interpreted as category 3 were benign, and the negative predictive value measuring the max-FLR was kept at 98% as long as the max-FLR was less than 4.0. Measuring the max-FLR may reduce unnecessary biopsies by 57.5% in the category 3 group.
CONCLUSIONS:
Combining conventional US categories and measuring max-FLR with elastography may be helpful in reducing the number of unnecessary biopsies in category 3 lesions.

Medical and Biotech [MESH] Definitions
Ultrasonography, Mammary
Use of ultrasound for imaging the breast. The most frequent application is the diagnosis of neoplasms of the female breast.
Breast Cyst
A fluid-filled closed cavity or sac that is lined by an EPITHELIUM and found in the BREAST. It may appear as a single large cyst in one breast, multifocal, or bilateral in FIBROCYSTIC BREAST DISEASE.
Fibrocystic Breast Disease
A common and benign breast disease characterized by varying degree of fibrocystic changes in the breast tissue. There are three major patterns of morphological changes, including FIBROSIS, formation of CYSTS, and proliferation of glandular tissue (adenosis). The fibrocystic breast has a dense irregular, lumpy, bumpy consistency.
Leg Dermatoses
A nonspecific term used to denote any cutaneous lesion or group of lesions, or eruptions of any type on the leg. (From Stedman, 25th ed)
Plasma Cell Granuloma, Pulmonary
A tumor-like inflammatory lesion of the lung that is composed of PLASMA CELLS and fibrous tissue. It is also known as an inflammatory pseudotumor, often with calcification and measuring between 2 and 5 cm in diameter.
