The aim of this study was to evaluate the usefulness of 64-channel multidetector row helical computed tomography (MDCT) in differentiating malignant and benign breast lesions, and also assess the histopathologic correlation.

Fourty-two breast cancer patients underwent preoperative dynamic MDCT, in which they were scanned with rapid injection of contrast media (3mL/s) after 30 seconds, 1minutes and 2minutes (early arterial, late arterial and delayed phase, respectively). The CT values and enhancement patterns of malignant lesions (n=42) and benign lesions (n=9) were evaluated. And enhancement effects of the malignant breast lesions using MDCT were compared with hisopathologic diagnosis and size.

The CT values of malignant breast lesions were higher than those of benign lesions in the three phases (P0.1), but well correlated with the microvascular densities of the breast cancers. The pathologic tumor size was best correlated with the size which measured in early arterial phases of dynamic CT (correlation coefficient=0.96, p<0.01).

The CT attenuation values and enhancement pattern of the breast lesions on MDCT may lead to more appropriated differentiation of malignant and benign breast lesions.
