Renal transplant scintigraphy is a non-invasive diagnostic modality, using radioactive isotopes, to assess renal transplant related complications. Renal scintigraphy images are acquired with a dynamic planar procedure using a radioactive isotope visualized on a gamma camera. The final result is a two-dimensional timeframe image. This enables visual inspection of arterial patency, tracer uptake indicating renal perfusion, and tracer excretion to the bladder 1.
This diagnostic modality is part of the standard renal transplant follow-up in many transplant centers, however, not included in current guidelines 2. It is considered a sensitive diagnostic tool for the assessment of urological and vascular complications and postoperative fluid collections. Also, early post-transplant procedures are used to assess renal transplant dysfunction, in particular delayed graft function 3-5.
The most frequently used radioactive isotope for transplant renal scintigraphy are Tc-99m MAG3 and Tc-99m DTPA. These tracers can be used for qualitative and quantitative assessment of renal transplant perfusion and excretion 6,7.
