The aim of our study is to assess the diagnostic value of Technituim-(99m)-Methyle diphosphonate ((99m)Tc-MDP) Bone scintigraphy in the assessment of children with back pain.
Included in this retrospective study were 68 child referred to us complaining of back pain (mean age of 13+ 2). There were 45 boys and 23 girls. All children have been investigated with conventional x-ray which revealed normal or inconclusive result. All underwent bone scintigraphy after the injection of (99m)Tc-MDP with calculated doses according to there body weights.
Bone scintigraphy revealed 17 (25%) abnormal scans in 11 boys and 6 girls. Scans findings were suggestive of spondylolysis (n=4); malignancy including primary tumors and metastases (n=3); infection including osteomyelitis and discitis (n=3); sacroiliitis (n=2); benign tumors (n=2); pseudo fractures in ribs (n=1); necrosis in femoral head epiphysis(n=1) and nonskeletal-renal retention due to hydronephrosis (n=1). Sensitivity, specificity and accuracy of bone scan in detecting gross skeletal abnormality as a cause for back pain were 94% and 100% and 99% respectively.
Bone isotope scan is a sensitive imaging modality in the assessment of pediatric patients with back pain. It is a reliable modality to detect and role out most benign and aggressive serious etiologies.
本研究旨在评估锝-(99m)-亚甲基二膦酸盐((99m)Tc-MDP)骨闪烁显像在评估背痛儿童中的诊断价值。
本回顾性研究纳入了68例因背痛前来就诊的儿童(平均年龄13±2岁)。其中男孩45例,女孩23例。所有儿童均接受了传统X线检查,结果显示正常或不明确。所有儿童在注射(99m)Tc-MDP后均接受了骨闪烁显像,根据体重计算剂量。
骨闪烁显像显示11例男孩和6例女孩中有17例(25%)扫描异常。扫描结果提示椎弓根峡部裂(n = 4);恶性肿瘤,包括原发性肿瘤和转移瘤(n = 3);感染,包括骨髓炎和椎间盘炎(n = 3);骶髂关节炎(n = 2);良性肿瘤(n = 2);肋骨假骨折(n = 1);股骨头骨骺坏死(n = 1)以及因肾积水导致的非骨骼-肾脏放射性滞留(n = 1)。骨扫描检测作为背痛原因的明显骨骼异常的敏感性、特异性和准确性分别为94%、100%和99%。
骨同位素扫描是评估背痛儿科患者时一种敏感的成像方式。它是检测和排除大多数良性和侵袭性严重病因的可靠方式。
