~(67)Ga SPECT显像对头颈部、胸腹部实体瘤病变程度和定位优于平面显像,对探查化疗后的残余病灶,随访观察化疗效果有重要意义.本文报道37例儿童实体瘤~(67)Ga SPECT显像结果.病例和方法:各种实体瘤患儿,男21例,女16例,年龄1～15岁.~(67)Ga剂量按体重公斤计算,最小用药量为80MBq,最大用到240MBq.注射后24、48h分别全身显像,根据临床和全身显像结果确定48h SPECT显像和局部平面显像部位.全部病例有胸部X线摄片、胸腹部CT及/或超声检查资料,部分病例有病理结果.
The ~(67)Ga SPECT imaging was superior to planar imaging in detecting head and neck, thoracic and abdominal solid tumors. It was of great significance to follow up the observation of residual chemotherapy after chemotherapy. 37 cases of solid tumor in children were reported in this paper. (67) Ga SPECT imaging results. Cases and methods: Children with various solid tumors, 21 males and 16 females, aged 1 to 15 years. ~(67)Ga dose calculated based on body weight kg, minimum dose 80MBq Maximal use of 240MBq. Whole body imaging at 24 and 48 h after injection, 48 h SPECT imaging and local planar imaging sites were determined based on clinical and whole body imaging findings. All cases had chest X-rays, chest and abdomen CT and/or Ultrasonography data, some cases have pathological results.
