SPECT、CT对脊柱关节病的诊断价值

The Evaluation of SPECT and CT in the Diagnosis of Spondyloarthritis

摘要: 为探讨CT、SPECT对脊柱关节病(SpA)的诊断价值,将临床诊断为SpA的102例患者,包括强直性脊柱炎(AS)63例,未分化脊柱关节病(uSpA)39例,分别进行CT骶髂关节扫描及SPECT全身及骶髂关节局部骨显像。结果显示,SPECT对AS的诊断总阳性率为50.8%(32/63),而且随着病情的发展而下降。CT对检查uSpA的阳性率仅为15.4%(6/39),远低于SPECT的阳性率82.1%(32/39)。因此,SPECT作为早期诊断SpA尤其是uSpA较CT敏感,并可作为AS治疗监测的重要手段,对临床SpA诊治具有重要意义。

Abstract: To evaluate the application of CT and SPECT in spondyloarthritis(SpA), 102 SpA patients, including 63 ankylosing spondylitis(AS) and 39 undifferentiated spondyloarthritis (uSpA) are performed by CT and SPECT. The results show that the total positive rates of SPECT is 50.8% (32/63), and they descend along with the development of state in AS. The positive rate of CT is only 15.4% (6/39) to the uSpA's exam, it is far lower than the positive rate 82.1%(32/39) of SPECT. SPECT in early diagnosis of AS and uSpA is more sensitive than CT. SPECT is a important means which can monitor the effect of AS therapy.
