CT and MRI examinations left behind in the radiology department

To retrospectively document the reported computerized tomography (CT) and magnetic resonance imaging (MRI) examinations that were left behind in our radiology department, to calculate their cost, and to determine possible sources of waste in order to draw attention to this subject.

The reported and billed CT and MRI examinations for 2003 that were not taken from the radiology department were documented, and the percentage they represented of all CT and MRI performed that year were determined. The total cost of the examinations, including contrast media, was calculated.

In all, 200 CTs out of 4390 and 95 MRIs out of 7003 were left behind in the radiology department during 2003. Total cost of the examinations, including the contrast media, was 31,320 YTL.

The percentages of CT and MRI examinations left behind in the radiology department were evaluated in this preliminary report. Since we did not find any similar study in the literature, we could not comment on the limits of acceptability of the results; however, we think other radiology departments should determine the percentages CTs and MRIs that are left behind and take the necessary precautions to minimize waste and reduce expenses.
