The individual nuclear size was studied in three groups of endometrial samples (simple hyperplasia -SH-, atypical hyperplasia -AH-, and well-differentiated adenocarcinoma -WDA-). The application of recent semiquantitative systems in combination with stereological methods permits a simple, quick and unbiased estimation of the volume-weighted mean nuclear volume vv(nucl). We have found an increas...

We performed voxel-guided morphometry (VGM) investigating the mechanisms of brain atrophy in multiple sclerosis (MS) related to focal lesions. VGM maps detect regional brain changes when comparing 2 time points on high resolution T1-weighted (T1w) magnetic resonace imaging (MRI). Two T1w MR datasets from 92 relapsing-remitting MS patients obtained 12 months apart were analysed with VGM. New les...

background: linear endoscopic ultrasonography (eus) is a proven modality for the diagnosis and treatment of different gastrointestinal lesions. the aim of this study was to describe the role of eus-fna in the evaluation of pancreatic and submucosal lesions. materials and methods: over a 1-year period, in a prospective descriptive study, patients referred to naft hospital, underwent linear eus. ...

Objective(s): Controversy exists about the localization of non-palpable breast lesions. In many countries, the gold standard for the diagnosis of these lesions is needle localization due to its accuracy. This study sought to compare the ultrasoundand radio-guided occult lesion localization (ROLL) as a simple method with the conventional procedures in terms of their diagnostic power. Methods: Th...

BACKGROUND AND PURPOSE Histopathologic studies have reported widespread cortical lesions in MS; however, in vivo detection by using routinely available pulse sequences is challenging. We investigated the relative frequency and subtypes of cortical lesions and their relationships to white matter lesions and cognitive and physical disability. MATERIALS AND METHODS Cortical lesions were identifi...

Introduction: Planning target volume (PTV) is generated from internal treatment volume (ITV) using four-dimensional computed tomography (4D-CT) for enhanced therapeutic gain in the stereotactic body radiotherapy for lung lesions (SBRT-Lung). This study aimed to propose a strategy to generate ITV on multiple-phase 3D-CT and enhance therapeutic gain in SBRT-Lung. <stron...

BACKGROUND AND PURPOSE Although the number of enhancing lesions is the typical outcome measure of choice in clinical trials in MS, a potentially more sensitive and statistically more powerful outcome measure is the volume of enhancing lesions. In this study, we assessed the distribution and statistical power of the volume of enhancing brain lesions as an outcome measure by means of their requir...
