Thallium-201/technetium-99m-RP-30A disparity in the course of myocardial infarction after attempted reperfusion.
Recent reports have established that 201Tl may be taken up in areas of recent myocardial infarction after myocardial blood flow is re-established. In addition, there is accelerated 201Tl "washout" from these regions producing a pattern of "reverse redistribution." We present a case in which these phenomena may have contributed to a disparity of findings between a 201Tl stress imaging study and a repeat stress imaging study performed with a [99mTc] isonitrile (99mTc-RP-30A).
