- BackgroundGround glass opacity (GGO) is the main HRCT feature representing alveolitis in systemic sclerosis-associated interstitial lung disease (SSc-ILD), but may also represent other conditions such as atelectasis or edema. It is unclear how much this is affected by the HRCT scan protocol used. We aimed to compare the performance of three different HRCT protocols to evaluate the degree of SSc-ILD related changes.MethodsEleven patients with SSc underwent chest HRCT scan by three different protocols: First, a supine scan after lying down for 15 minutes, then two scans in alternating order: A prone position scan, and a supine position scan after performing 10 deep breaths using a positive expiratory pressure (PEP) device. The HRCT scans were evaluated by the Warrick score system for ILD-related findings.ResultsThe three HRCT protocols were compared and resulted in different mean (95% CI) Warrick scores: 9.4 (5.3–13.4) in supine after rest; 7.5 (95% CI 3.8–11.1) in prone and 7.6 (95% CI 4.2–11.1) in supine after PEP. When comparing supine after rest to prone and supine after PEP, the latter two scans had a significantly lower score (p = 0.001 for both comparisons). In all cases, only sub-scores for ground glass opacities differed, while sub-scores for fibrosis-related changes did not change.ConclusionsDifferent HRCT scan protocols significantly altered the Warrick severity score for SSc-ILD findings, primarily because of changes in ground glass opacities. These differences may be clinically meaningful.
