2024年11月21日 · High-resolution CT (HRCT) of the chest, also referred to as HRCT chest or HRCT of the lungs has become routine. With progression of CT scanner technology, slice thickness of 0.5-0.625 mm can be obtained with a sharp reconstruction algorithm on …

2024年6月19日 · This helps radiologists to determine the certainty of usual interstitial pneumonia (UIP) diagnosis based on HRCT chest findings. The importance of this guideline is that (definite) UIP pattern on chest HRCT precludes the need for tissue diagnosis 1,2,5.

2024年5月22日 · HRCT chest is the main imaging technique for hypersensitivity pneumonitis 14. In population-based studies, the sensitivity of chest radiographs is relatively low 1 . Many patients have normal radiographs 3 .

2023年3月23日 · Ideally, an expiratory HRCT scan should be performed in all obstructive airway diseases. Some institutions make it routinely acquired in every initial HRCT assessment. Common indications include: obliterative bronchiolitis; cryptogenic organizing pneumonia; bronchial asthma; sarcoidosis; hypersensitivity pneumonitis; emphysema; bronchiectasis ...

2025年1月14日 · Reported HRCT features of asthma are non-specific as individual features, they include 2: bronchial wall thickening 2,3. expiratory air trapping. inspiratory decreased lung attenuation. small centrilobular opacities 6,8. bronchial luminal narrowing: reduced bronchoarterial-diameter ratio 7

2025年3月12日 · Chest CT or HRCT features include: pleural thickening or effusion. ground-glass densities 8. interstitial fibrosis (rheumatoid arthritis associated interstitial lung disease) reticulation. occurs in ~10% of RA patients 3. can have either a UIP (slightly more common 8) or NSIP pattern. organizing pneumonia. bronchiectasis. bronchiolitis obliterans

2025年3月17日 · The most common HRCT features include 6: patchy consolidation with a predominantly subpleural and/or peribronchial distribution. small, ill-defined peribronchial or peribronchiolar nodules. large nodules or masses. bronchial wall thickening or dilatation in the abnormal lung regions

2025年2月5日 · Epidemiology. Non-specific interstitial pneumonia typically tends to present in middle-aged adults 40-50 years of age 1.It may be more common in the White European population 9.. The overall prevalence is higher in women due to an association with collagen vascular disease, but the prevalence of idiopathic NSIP is similar in both genders.. Risk factors
