“…This pattern can virtually rule out pulmonary embolism as the culprit in the location of these abnormalities. Matched V/Q defects can be found in areas without any CT abnormalities as reported by Le Roux et al [29], Mahaletchumy et al [30], Bonnefoy et al [18], and Venegas et al [39].…”

“…(1) Reverse mismatch Bajc, Burger, Cobes, Goetz, Tipre, Bonnefoy, and Venegas discovered reversed mismatch patterns in their study [17,18,20,21,27,38,39]. This was attributed to non-segmental diversion of perfusion from ventilated areas (shunt perfusion) in Bajc et al study.…”

“…Three studies (Bahloul, Goetz, Tipre) observed tracheobronchial uptake [16,27,38] which was a unique finding in COVID-19 patients most likely due to tracheobronchial inflammation. [18,22,23,25,39].…”

Objective To investigate the outcomes of ventilation/ perfusion scintigraphy on the diagnosis of pulmonary embolism in coronavirus disease 2019 (COVID-19) patients, we performed a systematic review of the available literature. Materials and methodsPubMed and Scopus were systematically searched up to 4 June 2022, for relevant studies. We included studies on patients with COVID-19 who have performed ventilation/perfusion scintigraphy for diagnosis of pulmonary embolism to describe any diagnosis outcome. Irrelevant and non-English articles were excluded. ResultsOverall, 27 articles were included in our review. The database search yielded studies from PubMed, Scopus, and studies identified through reviewing the reference list of included studies. Extracted information from the included studies could be categorized into several aspects: Diagnosis of pulmonary embolism with Q single-photon emission computed tomography (SPECT) CT, Tracheobronchial uptake, Diagnostic value of V/Q rather than Q at diagnosis pulmonary embolism, Different characteristics (morphological alterations) of COVID-19 in ventilation orperfusion scan, the prevalence of pulmonary embolism with Q or V/Q criteria, and Design of radiotherapy planning in lung cancer patients with COVID-19. ConclusionDifferent perfusion patterns in COVID-19 are challenging but can be alleviated by adding SPECT/ computed tomography (CT) to lung perfusion scans. Although perfusion only SPECT/CT can rule out or rule in others in considerable number of patients, ventilation scan is still needed in certain patients. Nucl Med Commun
