Abstract
Nuclear cystography can be utilized in any nuclear medicine department that has a scintillation camera. Once the pitfalls and technical aspects are fully understood, the nuclear cystogram can be simply and accurately performed. Potential pitfalls include: patient apprehension; introducing the radionuclide into the saline bottle instead of the catheter; radionuclide interference from previous studies; unsatisfactory positioning; and improper removal of the catheter.
