Figure 4. (a) Anterior and (b) left lateral views of dynamic images (five frames, every 2 s) obtained immediately after the injection of 99Tcm-macroaggregated albumin via the left A6. Schema of the images is also shown. The left S6 pulmonary parenchyma was initially visualized (arrow heads), followed by the left ventricle (thick arrows). Note that the infused 99Tcm-macroaggregated albumin is visible within the microcatheter in the first frame (thin arrow); in the later phases, the compound is visible in the descending aorta, spleen and kidneys.
