A lung scan was incorrectly performed at Wesley Medical Center in Wichita,
Kansas last Friday, the 4th of May. It was reported [to the State] at approximately 1500 [CDT] on 5/7/2018. The DTPA [pentetic acid] dose was supposed to go through a nebulizer, and an MMA [methylmalonic acid] dose was supposed to be injected for perfusion, but they accidentally injected the DTPA instead. The patient was able to go through the scan as normal, but the end result is that 40 mCi of DTPA (what should have been the MMA dose, by [the State's] understanding) were injected instead of 4 mCi (what should have been the DTPA dose). The bladder dose was over 5 rads.
A full report has been promised by the licensee tomorrow, which will be forwarded to [the NRC] and entered into NMED [Nuclear Material Events Database].
It is unknown if the patient and the prescribing physician have been notified at the time of this report.
