Ventilation/Perfusion PET/CT With Galligas and 68Ga-MAA for Regional Lung Function Assessment After Pulmonary Embolism

In patients with pulmonary embolism (PE), after three or six months of anticoagulation, persistent dyspnea and impairment of quality of life are observed in at least 30% of cases. The "RAMBO" trial is a French academic, multicenter, randomized (1:1 ratio), parallel arm, controlled, that aimed to assess the efficacy of pulmonary rehabilitation (PR) on the quality of life in patients with an acute symptomatic PE treated with anticoagulant therapy during at least 3 months and who present an impairment of quality of life and/or persistent dyspnea despite anticoagulant therapy. Ventilation/Perfusion (V/Q) PET/CT is a novel imaging modality for the assessment of regional lung function. The same carrier molecules as conventional V/Q imaging are used, but they are labeled with 68Gallium, a ß+ isotope, instead of 99mTc, allowing acquisition of images with PET technology. The EOLE study is an ancillary pilot study of the RAMBO trial, in which patients will benefit, in addition to the extensive work up scheduled as per study protocol, from a V/Q PET/CT scan before and after PR. The aim of the study is to assess the impact of PR on regional lung function with lung V/Q PET/CT imaging.
