“…The ten scan 'failures' occurred in two earlier series technically inadequate by current standards. From these data, especially the major prospective study by Wellman et al (1973) (Table 2), the conclusion may be drawn that a normal scan effectively excludes the possibility of arteriographically demonstrable emboli, provided that examination comprises four technically satisfactory views. The converse is of course not true: the positive lung scan is not proof of embolism.…”

SummaryThe advantages of lung scanning in suspected pulmonary embolism are its diagnostic sensitivity, simplicity and safety. The ability to delineate regional pulmonary ischaemia, to quantitate its extent and to follow its response to therapy provides valuable clinical data available by no other simple means. The negative scan effectively excludes pulmonary embolism but, although certain ofits features favour the diagnosis of embolism, the positive scan inherently lacks specificity and requires angiographic confirmation when embolectomy, caval plication or infusion of a thrombolytic agent are contemplated. The addition of simple ventilation imging techniques with radioxenon overcomes this limitation by providing accurate analog estimation or digital quantitation of regional ventilation: perfusion (V/Q) ratios fundamental to understanding the pathophysiologic consequences of embolism and other diseases of the lung.
