Objective:
To evaluate the diagnostic agreement of 3D pseudo-continuous arterial spin labeling (3D-pCASL) and ¹⁸F-fluorodeoxyglucose and ¹¹C-Methionine positron emission tomography-computed tomography(PET/CT) for brain disorders.
Method:
3D-pCASL and PET/CT were performed on 7 patients with different brain disorders, and the diagnostic agreement was assessed by visual observation.
Results:
Four tumor lesions presented hyperperfusion on 3D-pCASL, and hypermetabolism on PET/CT. One demyelinated lesion and one metabolic lesion showed hyperperfusion on 3D-pCASL, and one infected lesion showed hypoperfusion on 3D-pCASL ;all these three lesions showed hypermetabolism on PET/CT.
Conclusion:
3D-pCASL can non-invasively evaluate the perfusion state of the brain disorder in vivo and have a good dignostic consistency with PET/CT.
