Since Ernst first demonstrated the possibility of pulmonary perfusion scanning with 198Au absorbed on charcoal particles a little more than a decade ago, lung scanning has become an extensively used diagnostic procedure. Its routine clinical application did not become practicable, however, until Taplin perfected the use of labelled macroaggregated human serum albumin (Iodine-131 MAA). Unfortunately, somewhere along the way, the procedure has been widely misrepresented as a potential replacement for pulmonary angiography, rather than a complement are to it since the two are in no way competitive. |
