Arteriography Pulmonary The real-time nature of pulmonary arteriography allows for high accuracy for delineating the angioarchitecture and detection of flow characteristics such as the early draining vein. Pulmonary angiogram is the reference standard to detect reperfusion of a treated AVM, but the angiogram is performed as a part of the treatment protocol and not done as a diagnostic test [10]. In patients who have inconclusive findings on CT, pulmonary angiography can assess recanalized PAVMs. Pulmonary Arteriovenous Malformation (PAVM) CT Chest With IV Contrast The high natural contrast inherent to pulmonary anatomy on noncontrast CT and the small risk of air embolism while administering IV medications renders CT chest with IV contrast unnecessary in the diagnosis of PAVM [10]. Artifacts from the embolic material limits the usefulness of contrast enhancement as a tool to evaluate reperfusion [47]. The role of contrast-enhanced CT has been studied after embolotherapy for PAVM in the context of detecting systemic collaterals by Brillet et al [29] in 32 patients. They found systemic collaterals in 13 patients that would otherwise have been missed on noncontrast CT. The role of contrast-enhanced CT scan after PAVM embolization is unclear. Cross-sectional anatomy displayed on CT chest with IV contrast is useful in further treatment planning if new or recanalized PAVMs are detected [10,27]. CT Chest Without and With IV Contrast The high natural contrast inherent to pulmonary anatomy on noncontrast CT and the small risk of air embolism while administering IV medications renders CT chest with IV contrast unnecessary in the diagnosis of PAVM [10].
