A 62-year-old woman with chronic nausea and epigastric pain underwent hepatobiliary scintigraphy. Gallbladder ejection fraction (GBEF) calculation suggested normal function. However, upon further review, a septate gallbladder was identified. This promoted a re-evaluation of the selected region of interest (ROI). The initial ROI included only the gallbladder fundus, leading to GBEF overestimation. Recalculation with a comprehensive ROI that encompassed both compartments yielded a lower GBEF, consistent with biliary dyskinesia or chronic cholecystitis. This case highlights the importance of ROI selection for accurate assessment of GBEF calculation in anatomical variations such as septate gallbladder and correlating functional studies with anatomical imaging.
一名患有慢性恶心和上腹部疼痛的62岁女性接受了肝胆闪烁扫描。胆囊射血分数（GBEF）计算显示功能正常。然而，进一步检查发现胆囊有分隔。这促使对选定的感兴趣区域（ROI）进行重新评估。最初的ROI仅包括胆囊底部，导致GBEF高估。使用包含两个腔室的综合ROI重新计算得出较低的GBEF，这与胆囊运动障碍或慢性胆囊炎一致。该病例强调了在胆囊分隔等解剖变异中，选择ROI对准确评估GBEF计算的重要性，以及将功能研究与解剖成像相关联的重要性。
