骨显像诊断原发恶性肿瘤骨转移的临床价值（附120例报告）

全身骨显像对于早期发现原发恶性肿瘤骨转移具有重要价值。本文对120例经手术病理或x线片等确诊的原发恶性肿瘤进行了全身核素骨显像,并对骨转移的分布、图形特点、骨转移发生率及临床意义进行了讨论。指出全身骨显像对诊断骨转移癌比X线片敏感。它比x线早期发现骨转移灶3～6个月。常见的原发恶性肿瘤中以肺癌、乳腺癌、直肠癌、前列腺癌的骨转移发生率较高。

Metastasis-survey by Whole Body Bone Scintigraphy,A Report of 120 Cases

Whole body bone scintigraphy (WBBS) provided a method of high sensitivity for early detection of the presence and extent of osseous metastases. 120 cancer patients with bone metastasis diagnoced by histology or radiography were studied by WBBS. The distribu- tion. pattern and incidence of secondary bone lesions were discussed. It was shown that WBBS was more sensitive than X- rays in detecting bone metastasis, preceding by 3-6 months ahead of radiography. The most frequent sites of bone metastases were rib, lumbar vertebra, thoracic vertebra, Pelvis, proximal end of fe- mur and humerus. The incidence of osseous metastases was high in cancers of lung, breast, rectum , prostate and na- sopharynx
