INTRODUCTION: The anatomy of the cochlea forms the basis for a successful cochlear implantation. Cochlear duct length (CDL) is defined as the length of the scala media as measured from the middle of the round window to helicotrema. Preoperative measurement of CDL is particularly important when precise intracochlear electrode array placement is desired. It can be done both histologically and radiologically. Preoperative high-resolution computed tomography (HRCT) scan which forms an integral part of cochlear implant workup is a useful tool to calculate CDL using 3D reconstructions...

OBJECTIVES: To evaluate the clinical characteristics of patients with interstitial lung disease (ILD) in the setting of a large cohort of systemic sclerosis (SSc) patients, and to analyse the differences according to the SSc subtype (following the modification of classification criteria of the American College of Rheumatology for SSc proposed by LeRoy and Medsger), factors are associated with moderate-to-severe impairment of lung function, as well as mortality and causes of death. METHODS: A descriptive study was performed, using the available data from the Spanish Scleroderma Study Group...

The most common delayed complication of sulfur mustard (SM) poisoning has been observed in the respiratory tracts. It was thus aimed to investigate the delayed respiratory complications in SM-exposed patients around 25 years before the study. Forty-three veterans with more than 25% disability of due to SM poisoning were investigated. Clinical examinations as well as pulmonary function test (PFT) were performed. High-resolution computed tomography (HRCT) of the lungs was done as clinically indicated. Triad of chronic cough, dyspnea, and expectoration were the most common symptoms that were recorded in 88...

BACKGROUND: Approximately one-third of individuals with interstitial lung disease (ILD) have associated connective tissue disease (CTD). The connective tissue disorders most commonly associated with ILD include scleroderma/systemic sclerosis (SSc), rheumatoid arthritis, polymyositis/dermatomyositis, and Sjögren's syndrome. Although many people with CTD-ILD do not develop progressive lung disease, a significant proportion do progress, leading to reduced physical function, decreased quality of life, and death...

Bronchiectasis in pediatric age is a heterogeneous disease associated with significant morbidity.The most common medical conditions leading to bronchial damage are previous pneumonia and recurrent lower airway infections followed by underlying diseases such as immune-deficiencies, congenital airway defects, recurrent aspirations and mucociliary clearance disorders.The most frequent symptom is chronic wet cough. The introduction of high-resolution computed tomography (HRCT) has improved the time of diagnosis allowing earlier treatment...

Spontaneous cerebrospinal fluid (CSF) otorrhea frequently occurs without temporal bone trauma, fracture, surgery, or any identifiable causes. It is usually associated with tegmen tympani defects of the temporal bone in adults. The congenital origin theory and the arachnoid granulation theory have been accepted to explain the tegmen tympani defect. Magnetic resonance imaging (MRI) and computed tomography (CT) are used to show the defects, brain tissue, and the meninges. We recently encountered three cases of spontaneous CSF otorrhea with a defect on the tegmental plate of the temporal bone...

OBJECTIVE: This study aimed to investigate the reliability of temporal bone high-resolution CT (HRCT) in patients with traumatic facial paralysis. METHODS: HRCT with cross-sectional scanning and multi-planar reformation (MPR) was performed on 26 cases with traumatic facial paralysis, and the preoperative imaging manifestations were compared with surgical findings. RESULTS: Preoperative HRCT revealed fallopian canal damage at the posterior genu in 1 case, geniculate ganglion in 22 cases, labyrinthine segment in 4 cases, tympanic segment in 13 cases and mastoid segment in 0 case, while surgical findings confirmed fallopian canal damage at the posterior genu in 7 cases, geniculate ganglion in 23 cases, labyrinthine segment in 4 cases, tympanic segment in 17 cases and mastoid segment in 7 cases...

Computer-Aided Nodule Assessment and Risk Yield (CANARY) is quantitative imaging analysis software that predicts the histopathological classification and post-treatment disease-free survival of patients with adenocarcinoma of the lung. CANARY characterizes nodules by the distribution of nine color-coded texture-based exemplars. We hypothesize that quantitative computed tomography (CT) analysis of the tumor and tumor-free surrounding lung facilitates non-invasive identification of clinically-relevant mutations in lung adenocarcinoma...

High-resolution computed tomography (HRCT) is a method of examination which is more precise than chest 2-rat in the diagnosis and monitoring of diseases of the lung tissue and the airways. Modern CT equipment enables a volume HRCT scan covering the whole lung tissue. HRCT slices can also be constructed from contrast-enhanced CT scans of the chest of the whole body. HRCT of the lungs can be applied to the diagnosis of both acute and more chronic diffuse diseases of the lung tissue and the airways. The best-known indications for HRCT include idiopathic interstitial pneumonias, such as idiopathic pulmonary fibrosis...

RATIONALE AND OBJECTIVES: The objective of this study was to assess the diagnostic utility of 3-tesla (3T) magnetic resonance imaging (MRI) of lungs in the detection of interstitial lung disease (ILD) in pediatric patients. MATERIALS AND METHODS: Twelve children (mean: 8.5 years, range: 4-12 years) with ILD were consecutively enrolled in this prospective study. HRCT and 3T lung MRI were performed in all patients within 2 days of each other. The sensitivity, the specificity, the positive predictive value, and the negative predictive value of detecting lung abnormalities related to ILD with 3T lung MRI were calculated, with high-resolution computed tomography (HRCT) as a standard of reference...

We conducted a prospective study to assess the value of high-resolution computed tomography (HRCT) in identifying facial nerve variations in patients with congenital aural atresia and to determine how they affect otologic reconstruction surgery. Our study population was made up of 65 patients (69 ears) aged 6 to 22 years (mean: 13.7) without regard to sex. They were classified into three groups according to their scores on the Jahrsdoerfer grading scale: 46 ears scored 8 or more, 18 had a score of 6 or 7, and 5 scored 5 or less...

OBJECTIVES: To apply the Delphi exercise with iterative involvement of radiologists and pulmonologists with the aim of defining a structured reporting template for high-resolution computed tomography (HRCT) of patients with fibrosing lung disease (FLD). METHODS: The writing committee selected the HRCT criteria-the Delphi items-for rating from both radiology panelists (RP) and pulmonology panelists (PP). The Delphi items were first rated by RPs as "essential", "optional", or "not relevant"...

BACKGROUND: Anti-aminoacyl-tRNA synthetase (ARS) antibodies have been detected in patients with polymyositis/dermatomyositis (PM/DM) and are especially correlated with interstitial lung disease (ILD). The aim of this study was to clarify the clinical features of patients with anti-ARS antibody positive idiopathic interstitial pneumonias (IIPs). METHODS: Patients were classified into three groups: 1) IIP with anti-ARS antibodies (ARS(+)IIP), 2) IIP without anti-ARS antibodies (ARS(-)IIP), and 3) PM/DM-associated ILD with anti-ARS antibodies (ARS(+)PM/DM-ILD)...
