病理证实的130例脊柱疾病核素骨显像研究

Comparison between Radionuclide Bone Scan and MRI、CT、X ray Imaging in the Diagnosis of Spinal Diseases Confirmed by Histopathalogy

目的 :比较核素全身骨平面显像和MRI、CT及X线诊断脊柱转移瘤及其他脊柱疾病的价值。材料和方法 :1 3 0例经病理证实的脊柱疾病患者行99mTc MDP全身骨显像 ,其中 1 0 4例同期行MRI、6 1例行CT、1 0 7例行X线片检查。结果 :骨显像的诊断灵敏度为 :转移瘤 91 .7%,原发骨恶性肿瘤 73 .3 %,良性肿瘤 5 4.2 %,瘤样病损 81 .8%,炎性病变 1 0 0 %,压缩性骨折 1 0 0 %。6 1 .1 %的转移瘤患者伴有其他部位骨骼的异常浓聚或稀疏灶。结论 :核素骨显像诊断骨转移瘤最有效 ;其他脊柱疾病 ,几种影像技术各有其优势 。

Purpose: To compare the diagnostic value of radionuclide bone imaging and that of MRI、CT、X ray photography in spinal metastases and other spinal diseases. Materials and Methods: Radionuclide whole body bone scan with 99m Tc MDP was performed in 130 patients with various spinal diseases confirmed by histopathology. MRI, CT and X ray were performed in 104,61 and 107 patients respectively. Results: The sensitivities of bone scan for metastatic tumor, primary bony malignancy and benign tumors, tumor like lesions, inflamma tory diseases and compressed fractures were 91.7%, 73.3%, 54.2%, 81.8%, 100% and 100%, respectively. In 22 of 36 (61.1%) patients with metastases, high uptake was noticed in multiple bony structures. Conclusion: Radionuclide bone imaging is of value in the diagnosis of spinal metastases. For non metastatic spinal diseases, bone scan might be helpful in judging the extent and the characteristics of the lesions.
