Similarly, on ROC curve analysis, the CaM scores confirmed the highest performance (AUC ROC CaM vs. Using SRM, the CaM was significantly more responsive to detect the changes due to treatment than the CoVR. The HRCT scores changed moderately over the follow-up period.

Results: During 1-year, lung involvement was stable/improved in 17 of 31 patients (54.8%), and worsened in 14 patients (45.2%). Receiver operating characteristic (ROC) curves analyses assessed the sensitivity and specificity of the two methods to discriminate between clinically relevant and no (relevant) progression, using judgement of the experts as gold standard (external responsiveness). Internal responsiveness over 1-year was evaluated with standardized response mean (SRM). The HRCT abnormalities were scored according to a CoVR (Warrick method) and a quantitative CaM. HRCTs were collected at baseline and after 1-year. Methods: Thirty-one patients were included in this retrospective cohort. Background: The aim of this study was to evaluate and compare the internal and external responsiveness of a computer-aided method (CaM) with a conventional visual reader-based score (CoVR) for measuring interstitial lung disease (ILD) in patients with systemic sclerosis (SSc) on high resolution computed tomography (HRCT). Our study showed that post-processing of the CT data with the use of Osirix Lite DICOM Viewer might be a valuable method of quantitative analysis of pulmonary involvement in sarcoidosis.Ībstract. Also, significant correlations between densitometric parameters and the results of PFTs were demonstrated, including correlation between CT-LV and TLC (R=0.7). Furthermore, SDLR was significantly higher in patients with lung fibrosis comparing to those with isolated MHL and MHL with pulmonary involvement (median 163.6 vs 137.4). Kurtosis was significantly lower in patients with lung fibrosis comparing to those with mediastinal and/or hilar lymphadenopathy (MHL) and pulmonary involvement (median 1.49 vs 1.93). Following densitometric parameters were measured: CT-derived lung volume (CT-LV), mean lung attenuation (MLA), kurtosis, skewness and standard deviation of lung radiodensity (SDLR).

Post-processing analysis of CT data was carried out using OsiriX Lite software (Pixmeo, Switzerland).
We included contrast-enhanced thorax CT examinations of 80 patients with sarcoidosis.

The aims of the study were as follows: (1) to assess the utility of the open-source, free of charge DICOM Viewer software in quantitative analysis of pulmonary involvement in sarcoidosis (2) to compare the parameters of quantitative CT analysis with the results of pulmonary function tests (PFTs). Hitherto, no widely accepted method of quantitative assessment of pulmonary involvement in sarcoidosis has been established. Although it has significant limitations associated with radiation exposure, CT scanning is also occasionally used to follow-up patients with sarcoidosis. Computed tomography (CT) plays a pivotal role in the initial evaluation of patients suspected of sarcoidosis.
