目的 :探讨MDP全身骨显像时骨外软组织浓聚的临床意义及影像对比分析。材料与方法 :原发肿瘤的病理类型 :肺腺癌2例 ,肺小细胞癌1例 ,肝癌2例 ,鼻咽癌、食管癌、胃癌、直肠癌、骨肉瘤、恶性神经鞘瘤各1例。检查方法 :静脉注射99mTc -MDP760～1110MBq,于注射后3～6小时进行检查。使用ElscintAPEX -6型SPECT机。结果 :骨外软组织单一显像11例 ,多病灶显像1例。分别为肺4例 ,肝、胸壁、肌肉组织及颈部淋巴结各2例。影像学对比 :全身骨显像骨外软组织浓聚 ,与CT、MR、X线、B超检查对比结果部位相符。结论 :核素骨显像骨外软组织浓聚骨显像剂具有一定临床意义 ,应结合临床综合判断 ,注意排除各种软组织异常摄取的原因 ,尤其肿瘤患者应首先考虑软组织恶性肿瘤存在的可能
Objective: To explore the clinical significance and imaging contrast analysis of extra-fracture soft tissue concentration in MDP whole-body bone imaging. Materials and Methods: Pathological types of primary tumor: 2 cases of lung adenocarcinoma, 1 case of small cell lung cancer, 2 cases of hepatocellular carcinoma, 1 case of nasopharyngeal carcinoma, esophageal carcinoma, gastric cancer, rectal cancer, osteosarcoma, and malignant schwannoma . Inspection method: intravenous injection of 99mTc-MDP760-1110MBq, 3-6 hours after the injection for examination. An Elscint APEX-6 SPECT machine was used. Results: There were 11 cases of extraosseous soft tissue single imaging and 1 case of multifocal imaging. There were 4 cases of lung, 2 cases of liver, chest wall, muscle tissue and cervical lymph nodes. Imaging comparison: Bone scans of the whole body were compared with those of CT, MR, X-ray and B-ultrasound examinations. Conclusion: Bone scintigraphy for extracranial soft tissue with bone scintigraphy has certain clinical significance. It should be combined with clinical comprehensive judgments to avoid the abnormal uptake of all kinds of soft tissues. In particular, tumor patients should first consider the possibility of the presence of soft tissue malignancy.
