Splenic switch-off in MPI studies denotes a visually (qualitatively) reduced splenic radiotracer<span> signal during adenosine stress and is considered indicative of sufficient cardiac vasodilation. In this study, we examined semi-quantitative and quantitative approaches to splenic switch-off assessment using [</span></span></span><sup>15</sup>O]H<sub>2</sub><span>O-PET with either summed activity images or calculated parametric splenic blood flow images.</span></p></div><div><h3>Methods</h3><p>Cohort 1: 90 clinical patients undergoing [<sup>15</sup>O]H<sub>2</sub><span>O MPI in whom adenosine response was considered clinically adequate were identified to characterize the corresponding splenic switch-off. Spleen stress/rest-ratio (SSR-ratio) was calculated as spleen stress signal intensity/spleen rest signal intensity on both summed activity and parametric blood flow images.</span></p><p>Cohort 2: Twenty-five patients with repeat MPI due to suspected insufficient adenosine response were identified to observe if splenic switch-off on the initial MPI could predict the outcome of the repeat MPI.</p><p>Cohort 3: Fifty-four patients who were considered adenosine responders on MPI and who had a coronary angiogram (CAG) follow-up within 3 months after MPI served as a separate validation group.</p></div><div><h3>Results</h3><p><span>Splenic switch-off was present in most patients with a clinically sufficient adenosine response (Cohort 1), illustrated by both visual (74.4%–86.7%), semi-quantitative (summed activity images) (85.6%), and quantitative (parametric blood flow images) (92.2%) evaluation, which corresponds to the distribution in patients with sufficient adenosine response and follow-up CAG (Cohort 3).
