Introduction: Tumor volume delineation is the most important step in the radiation treatment planning. In this study the impact of PET/CT data on the tumor delineation precision of non-small cell lung cancer (NSCLC) was investigated. Methods: PET/CT images of 20 patients with primary NSCLC were obtained and imported to the treatment planning system for im...

encapsulating peritoneal sclerosis (eps) is a rare, acquired condition that has been described interchangeablywith peritoneal encapsulation (pe) as well as abdominal cocoon. eps causes complications for peritoneal dialysis (pd) patients. in eps, the small intestine is covered by a fibrotic and inflammatory peritoneal capsule that either partially or completely encases the bowel. for eps, there ...

The paper describes the development of a cognitive therapy (CT) program for post-traumatic stress disorder (PTSD) that is based on a recent cognitive model (Behav. Res. Therapy 38 (2000) 319). In a consecutive case series, 20 PTSD patients treated with CT showed highly significant improvement in symptoms of PTSD, depression and anxiety. A subsequent randomized controlled trial compared CT (N = ...

The authors present a case of a pneumatocele associated with blunt trauma in a child. An 11-year-old boy was admitted to the emergency department after he was knocked over and his chest was trapped under a soccer goal. Chest computed tomography (CT) revealed several cavities in the lobes of both lungs. The CT of the abdomen revealed traumatic laceration of the liver. The patient was treated con...

We report a case of a 92-year-old man complaining of epigastric pain, which an US first and a CT scan later revealed to be related to a large gallstone causing cholecystitis. After the patient had refused surgical treatment for this condition, he was again referred to our Emergency Department presenting with a clinical picture of gastric obstruction. A new CT scan showed the classic Rigler’s tr...

and was discharged after 8 days. Colonoscopy is a common and safe diagnostic and curative procedure. The incidence of perforation is 0.19 to 0.21% and usually happens after therapeutic procedures.1 Sigmoid colon is frequently involved. Pneumomediastinum and subcutaneous emphysema occurs in exceptional cases.2 The choice to perform conservative treatment or endoscopic clipping3-5 is determined b...

We consider the inverse problem of recovery of an initial condition of a hyperbolic PDE. This problem is also called sometimes “thermoacoustic tomography”. In the past publications both stability estimates and convergent numerical methods for this problem were obtained only under some restrictive conditions imposed on the principal part of the elliptic operator. In this paper logarithmic stabil...
