“…In a study comparing V/Q scintigraphy, V/Q-SPECT, and V/Q-SPECT/computed tomography (V/Q-SPECT/CT), the sensitivity and specificity of V/Q-SPECT/CT were found to be significantly higher than the others [5]. In PE due to COVID-19, as the pathology originates from more distal to the segmental arteries due to microvascular damage, the effective role of V/Q-SPECT/CT and perfusion-SPECT/CT (Q-SPECT/CT) has been shown in the diagnosis of these patients [6,7].…”
