Abstract Rationale 99m Tc-sestamibi single-photon emission computed tomography/computed tomography (SPECT/CT) is a cost-effective and accurate means of characterizing indeterminate renal masses. This is scant literature on 99m Tc-sestamibi protocol optimization. Methods We investigated the difference between modeled, quantitative 180-degree and 360-degree acquisitions for 99mTc-sestamibi SPECT/CT in a cohort of 50 patients who were prospectively enrolled on a scan-and-resect protocol. Two experienced, dual-boarded observers rated each renal mass for image quality (1–5 scale) and diagnosis (benign to malignant, 1…
