MAMMOGRAM
sensitivity, specificity, and accuracy rates in detection of intraductal spread were 55, 100, and 72%, respectively.
THIS MEANS THAT MAMMOGRAM FOUND "SOMETHING" IN 100% OF THE CASES AND IN 45% OF THE CASES IT TURNED OUT TO BE NORMAL--THAT IS WHY MAMMO WILL BE FOLLOWED UP WITH A CTI SCAN OR AN ULTRASOUND--TO SEE IF THE WOMAN ACUTALLY NEES A BIOPSY OR NOT.
ULTRASOUND
sensitivity, specificity, and accuracy rates in detection of intraductal spread were 89, 76, and 85%, respectively.
SENSITIVITY WAS BETTER THAN MAMMO BY A LONG WAY--THAT IS WHY US IS PRESENTLY AN ADJUNCT TO MAMMO. DON'T FORGET THAT CTI SCANS ARE 96% SENSITIVE!

The purpose of this study was to assess the role of US in the detection of intraductal spread of breast cancer in comparison with mammography (MMG) and MRI. In 46 patients with breast cancer, US features of the intraductal component were classified as ductal type or distorted type. Histopathologically, 29 of 46 (63%) cases had intraductal components, and the sensitivity, specificity, and accuracy rates in detection of intraductal spread were 89, 76, and 85%, respectively. Each US pattern demonstrated good correspondence to the histologic components, and the distorted type correlated well with comedo-type carcinoma. Mammography was performed in all cases, and the sensitivity, specificity, and accuracy rates in detection of intraductal spread were 55, 100, and 72%, respectively. In comedo type, MMG could diagnose the extent of intraductal spread more accurately compared with US examination. Magnetic resonance imaging comparison was available in 25 cases. Magnetic resonance imaging depicted intraductal extension as an enhanced area during the early phase of a contrast enhancement study with a sensitivity of 93%. Ultrasound and MRI were closely related in terms of morphologic characteristics: the ductal type of US image correlated well with linear enhancement on MRI, whereas the distorted type correlated with regional or segmental enhancement. Current US examination is useful in depicting the intraductal spread of breast cancer; however, US has a tendency to underestimate intraductal component of comedo type compared with MMG and MRI. |
