Abstract:
Objective: Study the morphology and kinetics characters in breast diseases by using helical CT,to assess the value of differential diagnosis in benign and malignant breast diseases.Methods: Forty-three focuses in thirty-eight patients were detected by using double row detector CT with histopathologic correlation.Analyzed the characters of morphology,the time-density curve and the enhancement rate of all focuses.Results: Of the 43 focuses,breast cancers were twenty-eight and benign diseases were fifteen. There were eleven pieces and thirty-two masses.Lobulation signs and spicule signs were twelve respectively,among twenty-one malignant masses.One had spicule sign and two had lobulation sign among eleven benign mas-ses.Twenty breast cancers had Ⅲ type time-density curve,eleven benign diseases had Ⅰ type curve,and there were some overlaps on Ⅱ type curve.Enhancement rate(E) reflected the blood kinetics of breast diseases.E 1min and E 3min were better than E 3min in differentiating benign and malignant breast diseases.Conclusion:Lobulation signs and spicule signs are more often found in malignant lesions than in benign lesions.Early enhancement rate and time-density curve present some important information in differentiation.Synthesizing all these specialties can promote the diagnosis accuracy.
