摘  要:目的比较^18F—FDG符合线路显像和^99Tc^m-MDP骨显像对恶性肿瘤及其转移灶的诊断效能。方法临床明确的恶性肿瘤患者71例,3周内先后行^18F—FDG和^99Tc^m-MDP显像,以手术或穿刺病理、其他影像学方法和随访等结果为标准,对比2种显像方法在成骨性、溶骨性和混合性骨转移灶的诊断差异(χ^2检验),计算其诊断灵敏度、特异性、准确性、假阳性率、假阴性率、阳性和阴性预测值。结果(1)71例患者共发现包括原发、转移和良性病灶350个,其中恶性病灶286个(81.7%)。^18F—FDG发现141个(40.3%),^99Tc^m-MDP发现209个(59.7%),χ^2=25.65,P〈0.01;两者共同发现恶性病灶(全为转移)65个(18.6%)^99Tc^m-MDP单独发现恶性病灶144个,^18F-FDG单独发现76个(χ^2=29.76,P〈0.01)。(2)^18F—FDG对65个和^99Tc^m-MDP对88个(144个中可区分类型的骨转移灶)骨转移病灶探查,成骨性、溶骨性和混合性病灶数前者分别为11(16.9%)、12(18.5%)和42(64.6%),后者为48(54.5%)、7(8.0%)和33(37.5%),χ^2=20.78,2.89,9.94,P均〈0.05。(3)^18F—FDG和^99Tc^m-MDP诊断27例有随访最终诊断者骨转移灶的灵敏度、特异性、准确性、假阳性率、假阴性率、阳性预测值、阴性预测值分别为11.72%(15/128)、91.67%(22/24)、24.34%(37/152)、8.33%(2/24)、88.28%(113/128)、88.24%(15/17)、16.30%(22/135)和53.91%(69/128)、75.00%(18/24)、57.24%(87/152)、25.00%(6/24)、46.09%(59/128)、92.00%(69/75)、23.38%(18/77),其中灵敏度、准确性、假阴性率、阳性预测值差异有统计学意义(χ^2=32.70~46.21,P均〈0.01);两法合计的诊断指标分别为60.94%(78/128)、70.83%(17/24)、62.50%(95/152)Objective To compare the diagnostic efficiency of ^18 F- FDG coincidence SPECT/CT and ^99Tc^m- MDP whole body bone scan (WBBS) in detecting malignancy. Methods A total of 71 cases (male 45, female 26, mean age 59.2 + 15.4 years) with clinically confirmed malignancy underwent both ^99Tc^m- MDP WBBS and ^18F-FDG coincidence imaging within three weeks. The sensitivity, specificity, accuracy, positive and negative prediction value of these two imaging methods in detecting bone metastases were compared based on the results from pathology or clinical follow-up, x2test was used for data analysis. Results A total of 350 lesions (including primary, second malignancy and benign disease) in 71 patients were evaluated. 81.7% (286/350) malignant lesions were identified by either ^99Tc^m-MDP WBBS (209/350, 59. 7% ) or ^18F-FDG coincidence imaging ( 141/350, 40.3% ) (χ^2 = 25.65, P 〈0. 01 ). The imaging findings of osteoblastic, osteolytic, mixed types of bone metastases by ^99Tc^m-MDP WBBS and ^18 F-FDG coincidence imaging were significantly different (χ^2 = 20.78,2.89 and 9.94, all P 〈 0.05 ). The sensitivity, specificity, accuracy, false-positive, false-negative, positive and negative predictive values for detecting bone metastases by ^18 F-FDG coincidence study and ^99Tc^m-MDP WBBS were as follows: 11.72% ( 15/128), 91.67%(22/24), 24. 34% (37/152), 8. 33% (2/24), 88. 28% (113/128), 88. 24% (15/17),16.30% (22/135); and 53.91% (69/128), 75.00% (18/24), 57.24% (87/152), 25.00% (6/24), 46.09% (59/128), 92.00% (69/75), 23.38% (18/77). The sensitivity, accuracy, false-negative, positive-predicting value of the two methods had been significant different (χ^2 = 32.70- 46.21, all P 〈 0.01 ). When two methods were combined, the diagnostic efficiency could been improved. Conclusion The ^99 Tc^m- MDP WBBS and ^18F-FDG coincidence imaging has a complementary role in detecting bone metastases.
