 The investigators aim to evaluate the role of 68Ga-DOTA-NOC PETCT in patients with idiopathic pulmonary fibrosis, in particular in patients with a diagnosis of IPFUIP idiopathic pulmonary fibrosis, diagnosed based in the American Thoracic Society and European Respiratory Society criteria and in forms of NSIP non-specific interstitial pneumonia. PETCT imaging data will be compared with HRCT high-resolution computed tomography findings to assess disease extension, early disease detection and to non-invasively detect somatostatin receptors expression at lung level in these patients, with potential therapeutic implications.
