Y Ren, K Wang, J Q Zhang
Objective: The aim of this study is to explore the correlation between radiological classification on HRCT and effects on surgery with hearing improvement in otosclerosis. Method: Thirty three patients (66 ears) with otosclerosis were enrolled to this study, who would be done operation using Fischs stapes surgery technique. All patients were classified according to axial HRCT preoperatively. All patients were evaluated by pure tone test preoperatively and 6 months postoperatively. Correlation between radiological classification and hearing effects were studied...

OBJECTIVES: To predict round window niche (RWN) visibility using high-resolution computed tomography (HRCT). MATERIALS AND METHODS: We retrospectively reviewed the pre-surgical axial HRCT scan of 110 patients who underwent cochlear implantation and compared the CT visibility of RWN with the intraoperative findings by reviewing the operative notes and replaying the surgical video recording. The shape of RWN was determined using the HRCT slice with maximum RWN visibility...

BACKGROUND: Mycoplasma pneumoniae (MP) is the primary cause of community-acquired pneumonia. We aimed to evaluate the correlation between clinical features, with special reference to hypoxemia and the total affected area obtained using high-resolution computed tomography (HRCT). METHODS: Medical records of MP pneumonia patients > 15 years of age at Kyorin University Hospital between January 2006 and November 2013 were reviewed retrospectively and compared to patients with Streptococcus pneumoniae pneumonia, diagnosed between January 2013 and September 2014...

BACKGROUND: Chest computed tomography (CT), including high-resolution CT (HRCT), has become an integral part of modern healthcare. It enables the physician to arrive at a diagnosis using a noninvasive approach. Our practice has shown that various chest CT scans without intravenous (IV) contrast, including HRCT, have no proper clinical indication. For the same reason, we have assessed the appropriateness of chest CT without IV contrast based on the evidence-based American College of Radiology (ACR) appropriateness criteria...

Background: Dental laboratories include many hazards and risks. Dental technicians working in an unfavorable work environment in Turkey and other parts of the world may develop pneumoconiosis as a result of exposure to dust, depending on exposure time. In this study, we aimed to investigate the clinical and laboratory findings of dental technicians. Materials and Methods: The study consists of a case series. Between 2013 and 2016, a total of 70 who were working as a dental technician and referred to our clinic with suspicion of occupational disease were evaluated...

BACKGROUND: Limitations of coronary computed tomography (CTA) include false-positive stenosis at calcified lesions and assessment of in-stent patency. A prototype of ultra-high resolution computed tomography (U-HRCT: 1,792 channels and 0.25-mm slice thickness×128 rows) with improved spatial resolution was developed. We assessed the diagnostic accuracy of coronary artery stenosis using U-HRCT.Methods and Results:Seventy-nine consecutive patients who underwent CTA using U-HRCT were prospectively included...

The objective of this study was to report four children having juvenile dermatomyositis (JDM) with inverse Gottron sign along with a brief review of literature of similarly published cases. This is a retrospective review of case records of all children diagnosed with JDM at a single tertiary care centre in North India. Children who were found to have Gottron papules over palmar surface were identified. A total of 127 children were diagnosed with JDM in the last 24 years (1994-2017). Out of these 127 patients, 4 were found to have Gottron papules over palmar surface...

Background: Rheumatoid arthritis (RA) can affect the lungs in different manners, with interstitial lung disease (ILD) as the most serious manifestation. Although lung and joint compromise could be thought to evolve in parallel, there are data suggesting the opposite. In this study, we evaluated the relationship between lung and joint involvement in RA ILD. Methods: An observational cross-sectional study of RA ILD patients evaluated from January 2015 to February 2017...

Background: Chronic hypersensitivity pneumonitis (HP) is the most common cause of diffuse parenchymal lung disease (DPLD) in India. There is no data regarding the avian antigen exposure-associated DPLD from the country. Methods: Chronic HP from exposure to avian antigen was diagnosed when the high resolution computerized tomography (HRCT) showed features for HP and was supported by the history of exposure to pigeons, the presence of precipitin antibodies (IgG) to avian antigen in high titre with negative rheumatoid factor, antinuclear antibody, and no clinical clue for a collagen vascular disease...

This study aimed to evaluate the diagnostic yield of fiberoptic bronchoscopic (FOB) transbronchial biopsy and its relation with quantitative findings of high resolution computerized tomography (HRCT). A total of 83 patients, 19 males and 64 females with a mean age of 45.1 years diagnosed with sarcoidosis with complete records of high resolution computerized tomography were retrospectively recruited during the time period from Feb 2005 to Jan 2015.

INTRODUCTION: Gauzoma is an iatrogenic complication, which occurs rarely due to surgical team negligence. Depending on the sterility of the retained tissue, it can lead to life threatening surgical complications or may remain asymptomatic for many years and be detected incidentally in imaging studies. It may be mistaken as tumors or aneurysms. Thus, high clinical suspicion is needed to diagnose them in patients with past history of operation. Reporting Case: A 35 years old woman, a known case of scleroderma underwent open-heart surgery 20 years before being diagnosed as scleroderma, presented by dyspnea especially on activity...

Airway and vessel characterization of bronchiectasis patterns in lung high-resolution computed tomography (HRCT) images of cystic fibrosis (CF) patients is very important to compute the score of disease severity. We propose a hybrid and evolutionary optimized threshold and model-based method for characterization of airway and vessel in lung HRCT images of CF patients. First, the initial model of airway and vessel is obtained using the enhanced threshold-based method. Then, the model is fitted to the actual image by optimizing its parameters using particle swarm optimization (PSO) evolutionary algorithm...

OBJECTIVES: Oesophageal dilatation (OD) has been implicated in the pathogenesis of interstitial lung disease (ILD) in systemic sclerosis (SSc). The aims of this study were to explore the association of the OD and SSc-ILD on chest high-resolution computed tomography (HRCT), and to establish a cutoff point for the OD suggestive for the presence of a significant lung involvement. METHODS: The widest oesophageal diameter (WOD) was obtained on axial HRCT images. The parenchymal abnormalities on HRCT were coded and scored according to Warrick method...

Accurate segmentation of specific organ from computed tomography (CT) scans is a basic and crucial task for accurate diagnosis and treatment. To avoid time-consuming manual optimization and to help physicians distinguish diseases, an automatic organ segmentation framework is presented. The framework utilized convolution neural networks (CNN) to classify pixels. To reduce the redundant inputs, the simple linear iterative clustering (SLIC) of super-pixels and the support vector machine (SVM) classifier are introduced...

To investigate the clinical features, risk factors and outcomes of patients with interstitial pneumonia with autoimmune features (IPAF). A total of 1429 patients with idiopathic interstitial pneumonia (IIP) and undifferentiated connective tissue disease-associated interstitial lung disease (UCTD-ILD) were screened to identify patients who met IPAF criteria. Clinical, serological, and morphological features of patients with IPAF were characterized. Outcomes between patients with IPAF, UCTD-ILD, and IIP who were divided into idiopathic pulmonary fibrosis (IPF) and non-IPF groups were compared using survival as an endpoint...
