در این مقاله، به‌منظور رفع برخی محدودیت‌های شناسایی ساختمان تصاویر چندطیفی، از دادة SAR به‌منزلة مکمل استفاده می‌شود. روش پیشنهادی، برای استفادة هم‌زمان اطلاعات مفید رادار و استراتژی مبتنی‌بر تلفیق تصاویر، با هدف ساختمان، مطرح همچنین، ازآن‌جاکه انتخاب ویژگی نقش بسزایی طبقه‌بندی عوارض دارد، اغلب روش‌های مرسوم رایج زمینه، مانند الگوریتم ژنتیک، نیازمند داده‌های آموزشی‌اند؛ اما دردسترس‌نبودن همیشگی...

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia with airflow obstruction is a rare form of lung injury. All of the reported cases have been diagnosed by surgical lung biopsy. Only three of the reported cases presented with diffuse interstitial lung opacities on HRCT scans. We report three additional cases of this entity. All of the patients were female and presented with mild-to-mo...

Introduction: RA is a common collagen vascular disease that affects 1-2% of the general population. In nearly 50% of patients with RA, there is some form of extra-articular involvement in the disease process. Pulmonary complications of RA include pleural thickening or effusion, bronchiectasis, ILD, obliterative bronchiolitis, follicular bronchiolitis, pulmonary nodules, pulmonary hypertension, ...

OBJECTIVE To present the high-resolution computed tomography (HRCT) findings of pulmonary alveolar microlithiasis. METHODS The HRCT scans of 10 adult patients (seven females and three males; mean age, 38.7 years) were retrospectively analyzed. The films were studied independently by two radiologists. RESULTS The most common tomographic findings were ground-glass attenuation and linear subpl...

Articles in the past have described the radiological appearances of different interstitial lung diseases (ILDs) in varying levels of detail. However, these articles have generally been written for radiologists with a background in basic chest computed tomography (CT) interpretation. This article summarizes a basic approach for diagnosing ILDs on high-resolution CT (HRCT) for the nonradiologist ...

Background: The aim of the study was to evaluate radiographic features systemic sclerosis-associated interstitial lung disease. Patients and methods: 116 patients with disease (SSc-ILD) from 2010 2019 comprised our retrospective study. All were subject high resolution computed tomography (HRCT). ILD patterns classified into 7 as IIPs analyzed pathology. We chose two staging method semi-quantita...

Combining with signs of lung diseases in highresolution computed tomography (HRCT) images, this paper introduced texture feature extraction into HRCT images analysis. By analyses the relationship of texture features and imaging disease signs, selected three kinds relevant texture features, realized texture parameter extraction of any region of interest (ROI) and straight line, calculated area o...

A diagnosis of 'chronic cough' (CC) requires the exclusion of sinister pulmonary pathology, including infection and malignancy. We present a patient with a 3 month history of CC who had an extensive workup including a normal high resolution computed tomography of the chest (HRCT) 6 weeks prior to consultation at our center. He subsequently developed constitutional symptoms including weight loss...

Ten years of lung function and radiological findings in six non-smoking asbestos exposed subjects who had increased mid-expiratory flow rate (FEF 25-75%) as the only functional abnormality were prospectively analysed. A biphasic change in FEF25-75% was noted. It initially increased up to the fifth year, and then a decrease was seen. In the final three years of the study, FEF25-75% reduction cor...
