AIM To validate the feasibility of high resolution computed tomography (HRCT) of the lung prior to computed tomography angiography (CTA) in assessing incidental thoracic findings during endovascular aortic aneurysm repair (EVAR) planning or follow-up. METHODS We conducted a retrospective study among 181 patients (143 men, mean age 71 years, range 50-94) referred to our centre for CTA EVAR pla...
BACKGROUND In TB outbreaks, detecting active cases is the key step in stopping transmission of the disease. The aim of this study was to evaluate the role of high-resolution CT (HRCT) scanning of the chest in the investigation of a TB outbreak that developed in a cohort of 92 soldiers in the South Korean army. METHODS Outbreak investigation, including tuberculin skin test (TST), QuantiFERON T...
BACKGROUND Lung nodules are being detected at an increasing rate year by year with high-resolution computed tomography (HRCT) being widely used. Ground-glass opacity nodule is one of the special types of pulmonary nodules that is confirmed to be closely associated with early stage of lung cancer. Very little is known about solitary ground-glass opacity nodules (SGGNs). In this study, we analyze...
OBJECTIVE The purpose of our study was to evaluate the diagnostic performance of an artificial neural network (ANN) in differentiating among certain diffuse lung diseases using high-resolution CT (HRCT) and the effect of ANN output on radiologists' diagnostic performance. MATERIALS AND METHODS We selected 130 clinical cases of diffuse lung disease. We used a single three-layer, feed-forward A...
Fig. 1 : CT thorax showing asymmetrical fissural and perivascular nodules and linear opacities in both lungs Fig. 2 : FDG PET showing tracer uptake in bilateral pulmonary parenchyma corresponding to the HRCT findings. Fig. 3: Post treatment HRCT thorax showing regression in fissural and perivascular nodules but persistence in the linear opacities Fig. 4: Post treatment FDG PET showing significa...
1. linear and reticular opacities; 2. multiple nodules and nodular opacities; 3. parenchymal opacification, including consolidation and ground-glass opacity; 4. air-filled cystic lesions, including lung cysts, cystic lung disease, emphysema, and dilated bronchi (bronchiectasis); and 5. decreased lung attenuation, including mosaic perfusion, mosaic attenuation, and air trapping on expiratory sca...
OBJECTIVE To determine the frequency of HRCT findings and their distribution in the lung parenchyma of patients with organizing pneumonia. METHODS This was a retrospective review of the HRCT scans of 36 adult patients (26 females and 10 males) with biopsy-proven organizing pneumonia. The patients were between 19 and 82 years of age (mean age, 56.2 years). The HRCT images were evaluated by two...
مقطعنگاری رایانهای با دقت مکانی بالا (hrct) یک روش تصویربرداری پزشکی است که تصویری گویا از بدن انسان به منظور بررسی بافت ریه در اختیار قرار میدهد. این روش اندازهگیریهای دقیقی از الگوهای بافتی مربوط به بیماریهای ریه از جمله سیستیک فیبروز فراهم میآورد. سیستیک فیبروز یک بیماری مزمن ارثی و شایعترین اختلال اتومازول مغلوب در سفید پوستان است که عمدتاً ریهها و دستگاه گوارشی را تحت تأثیر ق...
The aim of this study was to describe a scoring system for high resolution computed tomographic (HRCT) scans analogous to the International Labour Office (ILO) scoring system for plain chest radiographs in patients with asbestos related disease. Interstitial fibrosis, pleural disease, and emphysema were scored, the reproducibility and the interobserver agreement using this scoring system were e...
