RATIONALE High-resolution computed tomography (HRCT) is an integral aspect of the evaluation of patients with suspected idiopathic pulmonary fibrosis (IPF). However, few studies have evaluated its use in a large cohort. OBJECTIVES To describe HRCT features in patients with mild to moderate IPF, compare diagnostic evaluations by a radiology core (three thoracic radiologists) with those by stud...

The present pilot study was undertaken to characterize the frequency of lung lesions in asymptomatic human deficiency virus (HIV) infected individuals with advanced HIV disease. Thirty two consecutive HIV+ homosexual males assessed for initiation of Pneumocystis carinii pneumonia (PCP) prophylaxis, were prospectively studied. All patients underwent a complete medical history, physical examinati...

OBJECTIVE The aim of this study was to evaluate the diagnostic accuracy of echo-planar diffusion-weighted magnetic resonance imaging (EP-DWI) and high-resolution computed tomography (HRCT) in the detection and localization of cholesteatoma. MATERIALS AND METHODS Fifty-four patients were prospectively included in this study. Patients with suspected primary or residual cholesteatoma were evalua...

cardiac or pulmonary abnormalities, or vascular diseases primarily affecting the small arteries or veins. In most cases, PVD and PH are assessed using techniques and imaging modalities other than high-resolution computed tomography (HRCT). However, in some patients, HRCT may be performed to determine whether lung disease is present as a cause of the patient’s disability or to evaluate specific ...

ABSTRACT PURPOSE To assess the usefulness of HRCT in diagnosis and follow up of pulmonary involvement in systemic sclerosis. MATERIALS and METHODS A total of 159 patients with systemic sclerosis, without overlap features, were studied. Sequential HRCT evaluation was realized in 138 patients. Semiquantification of HRCT findings was based on the grading systems introduced by Wells et al and Warri...

introduction: data on imaging findings in pulmonary complications of chemical agents is scarce. the current study aimed to evaluate radiological findings of late onset pulmonary complications in chemical warfare victims (cwv) and to guide pulmonologists in diagnosis of these subjects.   materials and methods: ninety- three male cwv were enrolled in this prospective study, 20-25 years (mean=23) ...

Introduction: Skull base and temporal bone fractures are frequently associated with severe high-velocity head trauma. Even though most of these fractures are not life-threatening, they are often associated with severe morbidity which has got a major impact on the quality of life. Conventional computed tomography (CT) has got its own limitations and often missed finer details of the temporal bon...

Pulmonary Langerhans cell histiocytosis (PLCH) affects mainly young, predominantly smoking adults with a peak at 20-40 years of age. Patients with PLCH often present with a nonproductive cough and/or dyspnea. High-resolution CT (HRCT) is the most important diagnostic modality in PLCH. The typical HRCT pattern combines small poorly limited nodules, cavitated nodules, and finally thick- and thin-...
