The human brain thalami play essential roles in integrating cognitive, sensory, and motor functions. In multiple sclerosis (MS), quantitative magnetic resonance imaging (qMRI) measurements of the thalami provide important biomarkers of disease progression, but late development and aging confound the interpretation of data collected from patients over a wide age range. Thalamic tissue volume los...
BACKGROUND The hematopoietic protein Granulocyte-colony stimulating factor (G-CSF) has neuroprotective and -regenerative properties. The G-CSF receptor is expressed by motoneurons, and G-CSF protects cultured motoneuronal cells from apoptosis. It therefore appears as an attractive and feasible drug candidate for the treatment of amyotrophic lateral sclerosis (ALS). The current pilot study was p...
OBJECTIVES The aim of the study was to clarify the clinical significance of single-photon emission computed tomography/computed tomography (SPECT/CT) imaging in terms of technetium-99m galactosyl human serum albumin (99mTc-GSA) scintigraphy. To this end, we examined the relationship using data from surgical records of 67 patients with hepatocellular carcinoma who underwent hepatectomy. MATERI...
BACKGROUND The purpose was to evaluate the efficacy of tumor volumetry on MRI as predictive of response to treatment with induction chemotherapy, comparing the results with endoscopy. METHODS Fifty patients with advanced squamous cell carcinoma of the head and neck (SSCHN) who underwent MRI volumetry before and after neoadjuvant chemotherapy consisting of docetaxel, cisplatin, and 5-fluoroura...
AIM To evaluate the diagnostic performance of computed tomography (CT) volumetry for discriminating the fibrosis stage in patients with nonalcoholic fatty liver disease (NAFLD). METHODS A total of 38 NAFLD patients were enrolled. On the basis of CT imaging, the volumes of total, left lateral segment (LLS), left medial segment, caudate lobe, and right lobe (RL) of the liver were calculated wit...
BACKGROUND Water displacement leg volumetry is a highly reproducible method, allowing the confirmation of efficacy of vasoactive substances. Nevertheless errors of its execution and the selection of unsuitable patients are likely to negatively affect the outcome of clinical studies in chronic venous insufficiency (CVI). DISCUSSION Placebo controlled double-blind drug studies in CVI were searc...
Liver transplantation is indicated for primary and salvage treatment of hepatic malignancies including hepatocellular carcinoma (HCC) and hepatic epithelioid hemangioendothelioma, end-stage liver diseases, acute liver failure, and congenital anatomical and metabolic liver diseases such as biliary atresia, Wilson’s disease and hemochromatosis. Living donor liver transplantation (LDLT) is more wi...
Methods We prospectively enrolled healthy 115 children and adolescents, mean age 12.4±4.1 years, range 4.4-20.3, with no acquired or congenital heart disease, no chronic illness or any competitive sports activities. Transversal routine 2D steady-state free-precession acquisition was used to cover the whole heart. We determined maximal and minimal volumes of both atria and calculated cyclic volu...
