Background <p>Dynamic two-dimensional (2D) planar renal scintigraphy is a widely used imaging modality for evaluating renal function, though its anatomical and quantitative accuracy is limited by overlapping structures. Recent advancements in single photon emission computed tomography/computed tomography (SPECT/CT) technology employ a multi-detector cadmium-zinc-telluride (CZT) ring configuration. This eliminates the need for camera rotation around the patient, reducing acquisition time and enabling high temporal resolution dynamic three-dimensional (3D) imaging. This technology may be particularly beneficial for kidney transplant patients.</p> Case presentation <p>We present a case of a 44-year-old male who underwent dynamic SPECT/CT renal scintigraphy with impaired urinary excretion following post kidney transplantation.</p> Conclusions <p>Dynamic SPECT/CT using a 3D-ring CZT-based camera demonstrated added diagnostic value in the presented renal scintigraphy application.</p>
