In 27 patients with normal hepatic function, delayed concentration of radioactivity (during 99mTc-RBC gastrointestinal bleeding studies) was compared with liver blood-pool activity. That is, for images at 4 to 24 hr postinjection, grading was accomplished by comparison to the liver blood pool (less than, equal to, or greater than hepatic activity). There was a correlation between the accuracy of scan interpretation (for active bleeding and localization) and the intensity of activity as related to the liver. This simple grading system may be useful for interpretation of delayed images during bleeding studies.
在27例肝功能正常的患者中，将放射性延迟浓聚（在99m锝标记红细胞胃肠道出血研究期间）与肝脏血池活性进行了比较。也就是说，对于注射后4至24小时的图像，通过与肝脏血池（低于、等于或高于肝脏活性）进行比较来完成分级。扫描解释的准确性（针对活动性出血和定位）与相对于肝脏的活性强度之间存在相关性。这种简单的分级系统可能有助于在出血研究期间对延迟图像进行解释。
