[Values of color Doppler flow imaging and imaging changes of breast fascia and ligament in differential diagnosis of small breast neoplasms].

BACKGROUND &

OBJECTIVE

Color Doppler flow imaging (CDFI) has been widely applied to the diagnosis of breast neoplasms. But combined use of CDFI and imaging changes of breast fascia and ligament (superficial and deep fascia, and Cooper's ligament) on the differential diagnosis of small breast neoplasms (< or =2 cm) has rarely been reported. This study was to explore the value of combined use of CDFI and imaging changes of breast fascia and ligament in differential diagnosis of small breast neoplasms.

METHODS

CDFI was performed on 110 patients with small breast neoplasms. Among them, 52 cases were diagnosed to be benign by pathologic examination after surgery, while the rest 58 were malignant. The blood flow and Doppler image inside and around the breast lesions were analyzed. Four grades were classified according to blood flow imaging. The infiltration of breast fascia and ligament was also considered. The CDFI result was compared with that of pathologic examination.

RESULTS

The correct diagnosis rates of CDFI in diagnosing benign and malignant small breast neoplasms were 90.4% and 84.5%, respectively. The false-positive and false-negative rates of CDFI were 9.6% and 15.5%, respectively. There were obvious differences in blood flow grading, systolic maximum velocity (V(max)), resistance index (RI), and imaging changes of superficial, deep fascia and Cooper's ligament between benign and malignant small breast neoplasms.

CONCLUSION

Combination of CDFI with imaging changes of breast fascia and ligament is valuable in clinical diagnosis and differential diagnosis of small breast neoplasms.
