Usefulness of selective arterial calcium injection tests for functional pancreatic neuroendocrine tumors

Abstract The selective arterial calcium injection (SACI) test is useful for patients with functional pancreatic neuroendocrine tumors (F-PNETs). This study evaluated which patients with F-PNETs would benefit from the SACI test. We retrospectively analyzed the preoperative findings of patients on com...
