diagnostic\naccuracy of nipple-centered radiate multiplanar reconstruction (NRMPR)images using multidetector row\nhelical computed tomography (MDCT), comparing it with conventional mammography. M ethods :\nOur subjects were 26 breast cancer patients with a total of 29 lesions who sequentially received contrastenhanced\nMDCT imaging for preoperative evaluation. We measured the maximum diameter of the\nbreast cancer in the direction toward the nipple on NRMPR images and mammography. All data were\ncorrelated with histopathological mapping of the specimens. Results : The tumor extent measured on\nNRMPR images and in pathological examinations ranged from 12.4 to 66.0mm (average, 28.0mm) and\n10 to 70mm (average, 27.9 mm), respectively. The correlation coefficient of the two measurements was\n0.898. On mammography, two lesions were not clearly identified. The correlation coefficient of\nmammography and pathological measurements was 0.554. Conclusions : The addition of NRMPR\nimages to mammography provides more information to evaluate breast cancer extension toward the\nnipple. Potentially, it provides a clue for selecting the appropriate surgical procedure or surgical\nresection margin for breast cancer.
