摘要
Abstract
Objective To compare the difference between single -photon emission computed tomography(SPECT) bone imaging and positron emission tomography/X -ray computed tomography(PET/CT) bone imaging and find the possible reasons. Methods The two patients underwent SPECT imaging and PET/CT whole-body scan, and the diagnostic sensitivity, accuracy and so forth were compared. Results The bone uptake mechanism of 18F-fluoride(PET/CT bone imaging agent) was similar to that of 99mTc-MDP(SPEC bone imaging agent), both of which could reflect local blood flow and activity level of bone metabolism. 18F-fluoride had higher congeniality with bone compared with 99mTc-MDP, so the resolution and sensitivity of PET/CT image were significantly higher than those of SPECT image. Conclusion The resolution and sensitivity of PET/CT image are significantly higher than those of SPECT image, but its application in clinical is quite limited due to its high expense and short half life of 18F.[Chinese Medical Equipment Journal,2012,33(6) :70-71]关键词
