Technetium-99m methylene diphosphonate (99mTc MDP) imaging was performed in 29 consecutive children with abdominal masses. Dynamic images of the inferior vena cava were obtained by injecting the radiotracer in the feet. Serial renal images were obtained for the next 30 min. Routine bone imaging was performed at about 3 hr. The radionuclide studies of the inferior vena cava accurately diagnosed total obstruction and displacement to the left but not partial obstruction and displacement to the right. The abnormalities on early renal imaging included displacement (14), distortion (seven), obstruction (eight), and nonvisualization (one). All patients with Wilms tumor (eight) had either nonvisualized or distorted renal parenchyma. Patients with neuroblastoma (17) and other tumors (four) had displacement and obstruction. Soft-tissue accumulation of 99mTc MDP was noted in two Wilms tumors and 12 neuroblastomas.
对29例连续性腹部肿块患儿进行了锝-99m亚甲基二膦酸盐（99mTc MDP）显像。通过在足部注射放射性示踪剂获得下腔静脉的动态图像。接下来的30分钟内获取连续的肾脏图像。约3小时后进行常规骨显像。下腔静脉的放射性核素研究准确诊断出完全阻塞和向左移位，但不能诊断部分阻塞和向右移位。早期肾脏显像的异常包括移位（14例）、变形（7例）、阻塞（8例）和不显影（1例）。所有肾母细胞瘤患者（8例）的肾实质均不显影或变形。神经母细胞瘤患者（17例）和其他肿瘤患者（4例）有移位和阻塞。在2例肾母细胞瘤和12例神经母细胞瘤中发现了99mTc MDP的软组织积聚。
