Evaluation of abnormal FDG uptake in IIM-ILD patients with different survival. A. Comparison of bilateral lung SUVmean in IIM-ILD patients who died within three months or survived beyond this threshold. B. Comparison of spleen SUVmean in IIM-ILD patients who died within three months or survived beyond three months. C. Correlation between bilateral lung SUVmean and spleen SUVmean in IIM-ILD patients. FDG: Fluorodeoxyglucose; IIM-ILD: Idiopathic-inflammatory-myopathy-related interstitial lung disease; SUVmean: mean standard uptake value
