Osirix dicom viewer
An excellent intra-reader reliability of HRCT findings among both readers was obtained.
Moreover, kurtosis correlated significantly with the mean lung attenuation (Spearman’s rho = 0.885 p = 0.0001). A significant association between the median values of kurtosis by both the quantitative OsiriX assessment and the HRCT semiquantitative analysis was found ( p < 0.0001). Intra-reader reliability of HRCT findings and feasibility of OsiriX quantitative segmentation was recorded. The results obtained were compared with those of HRCT semiquantitative analysis.
parameters of distribution of lung attenuation such as kurtosis and mean lung attenuation) of PF was independently performed on the same sections by a rheumatologist, independently and blinded to radiologists’ scoring, using OsiriX. For the assessment of the extension of PF, the adopted semiquantitative HRCT score ranged from 0 to 3 (0 = absence of PF 1 = 1–20 % of lung section involvement 2 = 21–40 % of lung section involvement 3 = 41–100 % of lung section involvement). Pulmonary involvement was evaluated in three sections (superior, middle and inferior). Chest high-resolution computed tomography (HRCT) examinations obtained from 10 patients with diagnosis of SSc were analysed by two radiologists adopting a standard semiquantitative scoring for PF.
To investigate the utility of an open-source Digital Imaging and Communication in Medicine viewer software-OsiriX-to assess pulmonary fibrosis (PF) in patients with systemic sclerosis (SSc).
