摘要
临床中PET-CT作为一种新型的非损伤性的诊断技术,能提供功能与解剖相结合的影像资料,现多用于肿瘤的诊疗。标准化摄取值(SUV)作为PET-CT中应用最为广泛的半定量分析指标,其对不同肿瘤良恶性鉴别诊断的界值将影响着最终的诊断结果、后续的治疗方案以及预后情况。对SUV的影响因素、校正方案以及利用SUV对不同肿瘤进行鉴别诊断的界值及其进展加以综述。尽管SUV对肿瘤的诊断没有公认的界值,但仍然是肿瘤诊断中重要的半定量指标。在临床工作中合理谨慎利用SUV进行诊断分析,可提高肿瘤诊断的灵敏度及特异度。
Whole-body PET-CT scanning has been used in the diagnosis and treatment of tumor to providing functional and morphological imaging. As the most widely used semiquantitative analysis index, the cutoff value of SUV would affect the final diagnosis, therapeutic regimen and prognosis estimation. Therefore, the article reviews the influential factors of SUV, its correction methods, its cutoff values of differential various tumors and the progress of SUV. Although there is no acknowledged cutoff value of SUV in tumor diagnosis, SUV is still an important semi-quantitative index, and its rational and prudent use would increase both of the sensitivity and specificity in tumor diagnosis.
