Studies have shown that weight loss is associated with adverse outcomes in all treatment modalities for esophagogastric carcinoma. Because of the increased prevalence of obesity and the effectiveness of perioperative nutrition, a number of patients are now obese or have normal body mass index (BMI) at the time of treatment. We investigated the relationship(More)
Cytomegalovirus (CMV) is the most common viral agent causing congenital infection in humans, affecting 0.2 to 2.4% of all live births. Symptomatic congenital CMV infection has previously been shown to cause low birth weight and prematurity. Whether or not asymptomatic congenital CMV infection, which represents the majority of cases (90 to 95%), affects(More)
OBJECTIVE To investigate the necessity of performing MRI in the radiotherapy position when using MRI for prostatic radiotherapy. METHODS 20 prostate patients received a CT, diagnostic MRI and an MRI scan in the radiotherapy position. The quality of registration between CT and MRI was compared between the two MRI set-ups. The prostate and seminal vesicles(More)
BACKGROUND Semantic dementia is a sporadic neurodegenerative disorder characterized by the progressive erosion of semantic processing and is one of the canonical subtypes of frontotemporal lobar degeneration. This study aimed to characterize the pattern of global and regional longitudinal brain atrophy in semantic dementia and to identify imaging biomarkers(More)
Placement of feeding tubes is a common procedure for general surgeons. While the advent of percutaneous endoscopic gastrostomy has changed and improved surgical practice, this technique is contraindicated in many circumstances. In some patients placement of feeding tubes in the stomach may be contraindicated due to the risks of aspiration, gastric paresis,(More)
This study investigated the compatibility of a head and neck immobilization device with magnetic resonance imaging (MRI). The immobilization device is used to position a patient in the same way as when receiving a computed tomography (CT) scan for radiotherapy planning and radiation treatment. The advantage of using immobilization in MR is improved accuracy(More)
