Computed tomography (CT) and magnetic resonance imaging (MRI) are excellent modalities for imaging patients with localizing signs of an intra-abdominal abscess. However, radionuclide techniques have an advantage over CT and MRI because they can evaluate the entire body for infection. In addition, radionuclides can noninvasively differentiate infection and inflammation from benign fluid collections. Radiopharmaceuticals available for imaging abdominal infection include gallium-67 citrate, indium-111, and technetium-99m-labeled leukocytes, and radiolabeled whole antibodies. The use of these radiopharmaceuticals for abdominal imaging is dependent on their biodistribution and mechanism of abscess localization.
计算机断层扫描（CT）和磁共振成像（MRI）是对有腹腔内脓肿定位体征的患者进行成像的极佳方式。然而，放射性核素技术相对于CT和MRI具有优势，因为它们可以评估全身是否存在感染。此外，放射性核素能够非侵入性地将感染和炎症与良性液体积聚区分开来。可用于腹部感染成像的放射性药物包括枸橼酸镓-67、铟-111以及锝-99m标记的白细胞，还有放射性标记的全抗体。这些放射性药物用于腹部成像取决于它们的生物分布和脓肿定位机制。
