12 de jul. de 2024 · Nodular pulmonary ossification may be seen in fibrotic areas. The positive predictive value of CT in the diagnosis of UIP is high and ranges from 70 to 100% 1. Similar to the pathology specimen, cross-sectional imaging also reveals heterogeneity, with patchy areas of fibrosis alternating with areas of normal lung 5.
In 2018 the guidelines were reviewed 5, and the main changes compared to the 2011 publication are: "possible UIP" no longer exists and has been replaced by "probable UIP". studies have shown that most of these patients were likely to have histopathologic UIP pattern despite the radiologic absence of honeycombing.
23 de mai. de 2024 · Non-specific interstitial pneumonia (NSIP) is the second most common morphological and pathological pattern of interstitial lung diseases after UIP. NSIP is commonly associated with connective tissue disease (CTD) and the underlying diagnosis and management are best decided by a multidisciplinary team.
4 de jun. de 2024 · Clinical presentation. Interstitial lung diseases classically produce the "3Cs": cough, clubbing of the nails, and fine crackles on auscultation 6. Functional respiratory tests commonly show an abnormal restrictive pattern and reduced diffusing capacity.
Case Discussion. These findings are consistent with UIP pattern. UIP has distinctive HRCT findings. If the UIP pattern is of unknown cause (i.e. idiopathic), the disease is called idiopathic pulmonary fibrosis (IPF).
19 de jun. de 2024 · The 2018 revised diagnostic HRCT criteria for usual interstitial pneumonia (UIP) pattern published by the American Thoracic Society, the European Respiratory Society, the Japanese Respiratory Society, and the Latin American Thoracic Association has converged to a similar categorization of the HRCT findings into four groups.
19 de jun. de 2024 · Citation, DOI, disclosures and article data. Idiopathic pulmonary fibrosis (IPF) is a clinical syndrome and considered the most common and the most lethal form of pulmonary fibrosis corresponding to the histologic and imaging pattern of usual interstitial pneumonia. It is more common in elderly men and diagnosed by:
20 de jul. de 2024 · For the transition zone, the PI-RADS assessment is primarily determined by the T2W score and sometimes modified by the DWI score. For the peripheral zone, the PI-RADS assessment is primarily determined by the DWI score and sometimes modified by the presence of dynamic contrast enhancement.
25 de jun. de 2024 · Pulmonary arterial hypertension is defined as a mean pulmonary arterial pressure >20 mmHg at rest and pulmonary capillary wedge pressure ≤15 mmHg measured by cardiac catheterization 3,4. It can result from either increased pulmonary venous resistance (most common) or increased pulmonary arterial flow, such as with a left-to-right ...
The webpage provides updated diagnostic HRCT criteria for usual interstitial pneumonia (UIP) pattern based on literature review and expert opinion of the Fleischner Society.
