A comparison of MR imaging, galactography and ultrasonography in patients with nipple discharge.

Background: The aim of this study is to assess the usefulness of three-dimensional contrast-enhanced magnetic resonance (MR) imaging, compared with galactography and ultrasonography(US).

Methods: Fifty-five patients with bloody nipple discharge were investigated retrospectively. All patients were examined by galactography, ultrasonography and MR imaging.

Accumulation of 4- and 5-ene steroid sulfates in human breast cyst fluids.

Gross cystic disease of the breast is one of the most common diseases of adult females. Breast cyst fluid contains various steroid hormones. In order to obtain more information about the concentrations of 4- and 5-ene steroids in human breast cyst fluids, levels of pregnenolone sulfate (PREGS), pregnenolone (PREG), dehydroepiandrosterone sulfate (DHEAS) and dehydroepiandrosterone (DHEA) were determined by high-performance liquid chromatography (HPLC).

Extension of breast cancer: comparison of CT and MRI.

Purpose: To compare three-dimensional (3D) helical CT with 3D MRI in the evaluation of intraductal spread of breast cancer.

Methods: Fifty patients with breast cancer were examined. Tumor size ranged from Tis to T2.
