The aim of this study was to describe the normal pattern of development and maturation of the foetal brain with respect to gestational age as assessed with magnetic resonance imaging (MRI) and to provide an overview of the possibilities of the technique. Foetal cerebral MRI was performed on 56 pregnant women between 19 and 37 weeks of gestation. Half-Fourier single-shot turbo spin-echo (HASTE), true fast imaging with steady precession (FISP), T1-weighted fast low angle shot (FLASH) two-dimensional (2D) and diffusion-weighted (DW) sequences with apparent diffusion coefficient (ADC) were obtained. Biometric parameters and developmental areas of the cerebral cortex were correlated to gestational age by using the Spearman rank correlation test. We found a negative correlation between the germinal matrix/biparietal diameter ratio and gestational age and a positive correlation between the germinal and cortical matrix when expressed as external intraocular diameter ratio ( R=0.452, p=0.02). The cortical mantle was correlated with biometric parameters, such as the biparietal diameter and the frontooccipital diameter, and with gestational age. The interhemispheric fissure, the parietooccipital fissure and the sylvian fissure were detectable by the 22nd week. In the grey matter, the mean ADC values varied from 1.76×10-3 mm2/s (at week 19) to 0.89×10-3 mm2/s (at week 37), whereas in the white matter, the values varied from 2.03×10-3 mm2/s (at week 19) to 1.25×10-3 mm2/s (at week 37). MRI provides a reliable valuation of brain maturation during pregnancy. [ABSTRACT FROM AUTHOR]

The purpose of this study was to evaluate the adjunctive diagnostic value of breast ultrasonography (US) in the study of benign ductal breast disease. Fifty-two patients underwent US examinations for bloody nipple discharge, palpable retroareolar masses, retroareolar opacities or ductal pattern on mammography. US enabled visualisation of mammary-duct ectasia (simple or pseudocystic, retroareolar and/or peripheral) and focal masses (endoluminal or periductal, with ill-defined or regular margins). All patients with nipple discharge underwent cytological evaluation. After the US examination, all focal masses with illdefined margins underwent fine-needle aspiration biopsy (FNAB), if necessary. The benign alterations were followed up. In 38/52 cases, US diagnosed mammary-duct ectasia and in 30/52 cases, the presence of focal masses (mean size 7 mm). In the nine women who underwent biopsy, histopathological evaluation diagnosed five solitary papillomas, one solitary papilloma with a focal area of ductal carcinoma in situ (DCIS), two multiple papillomas of the nipple and one papillomatosis. High-frequency US plays an important role in the detection of benign ductal disease both for the diagnosis and classification of focal masses and mammary-duct ectasia. US can be used as a complementary imaging method to galactography or as a valuable alternative when galactography is not available. [ABSTRACT FROM AUTHOR]
