BACKGROUND AND PURPOSE The purpose of this work was to demonstrate susceptibility effects (SusE) in various types of brain tumors with 3T high-resolution (HR)-contrast-enhanced (CE)-susceptibility-weighted (SW)-MR imaging and to correlate SusE with positron-emission tomography (PET) and histopathology. MATERIALS AND METHODS Eighteen patients with brain(More)
BACKGROUND Ghrelin is an appetite hormone that influences the gastrointestinal function and regulates energy metabolism. Growing evidence also suggests that this hormone plays a central role in immune modulation. Each surgical operation is followed by a series of inflammatory and metabolic changes that constitute the stress response. The aim of our study is(More)

Occasionally unretrieved gallstones can cause infection, adhesions, and obstruction. Furthermore, spilt stones can cause erosion into adjacent organs and can migrate to distant sites,(More)
Desmoid tumors are rare, benign fibroblastic tumors that are locally infiltrative and can cause extensive morbidity by destruction of adjacent vital structures. Due to the rarity of these tumors, evidence regarding optimal treatment protocols is drawn from case reports and single-arm series with small patient numbers. We report a case of a patient with a(More)
