hemangioma of the rib is a rare benign vascular tumor. herein, we report a 63-year-old man presenting with hemangioma of the left sixth rib. an osteolytic eccentric expansive mass with calcification and focal cortical disruption was detected on chest computed tomography (ct). the mass showed low 2-deoxy-2-[18f]-fluoro-d-glucose (18f-fdg) avidity on positron emission tomography. the patient unde...

Introduction: 99mTc-MIBI has been proposed for use as an imaging agent for various tumors, including breast cancer, lung cancer, lymphomas, melanomas and brain neoplastic lesions. Brain tumors are very common and radiotherapy being major part of treatment following surgery. After radiotherapy, deteriorating clinical status can be due to either radiation necrosis or recurrent tumor. Comput...

traumatic brain injury is a common entity. however cerebral infarction in infants is a rare entity while the diagnosis of this pathology in the pediatric population is usually difficult. the mild head trauma is rarely accompanied by intracranial injury and even less, with cerebral infarction. we herein report the first case of cerebral infarction after a mild brain trauma in a 2-year-old latin-...

Stroke is a leading reason for hospitalization in the Brazilian Health System. Computerized tomography has been indicated as the main diagnostic method to define stroke treatment. The aim of this paper was to evaluate the utilization of computerized tomography in hospitalizations due to stroke. The source of data was the Brazilian hospital information system. The study population comprised adul...

BACKGROUND Henoch-Schönlein vasculitis is the most common systemic vasculitis in children. Arthritis or arthralgia occurs in 80 % of patients. We believe this to be the first case report to describe the finding of polyarthritis in a fludeoxyglucose positron emission tomography-computed tomography scan in a patient with Henoch-Schönlein vasculitis without clinical signs of arthritis. CASE PRES...

This prospective study was done over seven years from 1996 to 2003 to investigate the chest computed tomography scan findings along with other radiologic examinations that included chest roentgenography and cranial computed tomography in children with tuberculous meningitis (TBM). Chest roentgenography demonstrated abnormal findings in 32 cases (43%) (hilar adenopathy, 32%; miliary pattern, 18%...

In accordance with other investigators (2, 3), the authors have reported an increase in (18)-F-fluorodeoxyglucose (FDG) uptake in the lung parenchyma of a small and heterogeneous group of ALI/ARDS patients using positron emission tomography/computed tomography scan in different phases of the disease. Additionally, the authors found heterogeneity in FDG uptake when regional metabolic activity wa...

A patient with metastatic calcification is presented and the contributions of plain film, computed tomography, and bone scintigraphy in the diagnosis are discussed. The patient had a long history of end-stage renal failure, and was previously receiving peritoneal dialysis and calcium supplements. His serum calcium level had been persistently elevated for several years without correction. Recent...

Background: This study assessed the optimal timing of computed tomography for detection of metastatic disease in locoregional lymph nodes in patients with rectal cancer who have undergone chemoradiotherapy. Materials and Methods: This observational retrospective study was performed in a single institution. All patients with locally advanced rectal cancer treated with chemoradiotherapy, followed...

Project ILATO focuses on Improving Limited Angle computed Tomography by Optical data integration in order to enhance image quality and shorten acquisition times in X-ray based industrial quality inspection. Limited angle computed tomography is indicated whenever specimen dimensions exceed cone beam limits or the object is impenetrable from certain angles. Thus, acquiring only a subset of a full...
