چکیده

This pictorial essay aims to present various lesions that could present as consolidations with diffuse of focal high attenuation on computed tomography, helping to make the diagnosis more confident and specific. The radiologic literature has limited information about such findings and the role of computed tomography in the differential diagnosis. The following diseases are presented: metastatic pulmonary calcification, pulmonary alveolar microlithiasis, amiodarone lung, talcosis, iodinated oil embolism, tuberculosis, silicoproteinosis, and amyloidosis. In conclusion, air-space consolidations can be seen in a wide variety of diseases affecting the lungs. The identification of the different patterns of consolidation with focal high attenuation narrows the differential diagnosis. We present a diagnostic approach based on appearance and distribution of these lesions.

Computed Tomography Imaging findings in Chemical Warfare Victims with pulmonary Complications

  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...

Varicella pneumonia in immunocompetent adults: report of two cases, with emphasis on high-resolution computed tomography findings.

We report two cases of varicella pneumonia in immunocompetent patients, with emphasis on high-resolution computer tomography manifestations. The predominant findings consisted of multiple bilateral nodules, ranging from 1-10 mm in diameter, with or without a surrounding halo of ground-glass attenuation. Other findings include ground-glass opacities, focal areas of consolidation and small pleura...

Validation of computed tomography-based attenuation correction of deviation between theoretical and actual values for four computed tomography scanners

Objective: In this study, we aimed to validate the accuracy of computed tomography-based attenuation correction (CTAC) using the bilinear scaling method.Methods: The measured attenuation coefficient (μm) was compared to a theoretical attenuation coefficient (μt ) using four different CT scanners and an RMI 467 phantom. The effective energy of the CT beam X-rays was calculated, using the aluminu...

Comment on “Computed Tomography Imaging Findings in Chemical Warfare Victims with Pulmonary Complications”

Dr.Mirsadraei and colleagues performed an interesting study about the lung HRCT findings in chemical warfare patients who suffering from long-term pulmonary complications. They found that air trapping and mosaic attenuation were the most common lung HRCT findings. Also they divided patients in different clinical entities according to the lung HRCT findings (Bronchiolitis Oblitrans, pulmonary fi...

CT findings of high-attenuation pulmonary abnormalities

OBJECTIVES: To review the computed tomography (CT) findings of common and uncommon high-attenuation pulmonary lesions and to present a classification scheme of the various entities that can result in high-attenuation pulmonary abnormalities based on the pattern and distribution of findings on CT. BACKGROUND: High-attenuation pulmonary abnormalities can result from the deposition of calcium or,...
