INTRODUCTION Endoscopy is an invasive procedure and finding noninvasive alternative tools in detection of probable upper gastrointestinal (GI) tract injuries following caustic ingestion is an area of interest. The present study aimed to evaluate the screening performance characteristics of thoraco-abdominal computed tomography (CT) scan in this regard. METHODS This prospective cross sectional...

BACKGROUND In evaluation of craniosynostosis patients in terms of neurodevelopmental delay, positron emission tomography computed tomography (PET-CT) scan can be used to assess brain abnormalities through glucose metabolism. We aimed to determine the unnecessity of PET-CT in this study. METHODS Thirty-eight patients diagnosed with craniosynostosis who underwent distraction osteogenesis from O...

OBJECTIVE The children's head injury algorithm for the prediction of important clinical events (CHALICE) is one of the strongest clinical prediction rules for the management of children with head injuries. The authors set out to determine the impact of this rule on the proportion of head injured patients receiving a CT scan in a major Australian paediatric emergency department. DESIGN Retrosp...

STUDY OBJECTIVE The purpose of this study was to compare the imaging findings of nontuberculous mycobacterial (NTM) infection in patients with normal and abnormal cystic fibrosis (CF) genotypes, and normal and abnormal alpha1-antitrypsin (AAT) phenotypes. DESIGN A retrospective review of medical records and chest CT scans from 85 patients with microbiologically proven NTM infection was perfor...

BACKGROUND The purpose of this study was to determine the detection rate of lung metastasis or a synchronous lung primary tumor in patients with newly diagnosed head and neck mucosal squamous cell carcinoma (SCC) and to determine factors that are associated with positive findings. METHODS This was a prospective cohort study of 102 patients with head and neck mucosal SCC diagnosed in a tertiar...

BACKGROUND Clinical assessment of acute appendicitis can be challenging due to atypical presentation. Computed-tomography can reduce negative appendectomies but not without adverse effects. We report our experience with preoperative CT-scan in patients with suspected acute appendicitis. PATIENTS AND METHODS During 3-years, 257 adult patients underwent appendectomy. We retrospectively reviewed...

Objective. Assessing the level of anxiety in oncology patients who underwent 18F-FDG PET/CT low dose scan and identifying the main reasons that generate anxiety. Material and Method. The study included 81 cancer patients submitted to the 18F-FDG PET/CT low dose scan. Patients filled in the Scan Experience Questionnaire and the State-Trait Anxiety Inventory (STAI) before and after 18F-FDG PET/CT...

introduction: nowadays virtual colonoscopy has become a reliable and efficient method of detecting primary stages of colon cancer such as polyp detection. one of the most important and crucial stages of virtual colonoscopy is colon segmentation because an incorrect segmentation may lead to a misdiagnosis.  materials and methods: in this work, a hybrid method based on geometric deformable models...

introduction delayed splenic rupture (dsr) is an unusual outcome following blunt abdominal trauma. although dsr is defined as bleeding more than 48 hours after blunt trauma in a previously hemodynamically stable patient, a review of the reported cases in the literature shows that in almost all of the cases the initial ct imaging revealed some form of damage to the spleen. case presentation here...
