Application of Simultaneous 18F-FDG PET/MRI for Evaluating Residual Lesion in Pyogenic Spine Infection: a Case Report.

Magnetic resonance imaging (MRI) is the preferred imaging method for evaluating treatment response in spine infection. However, there are still no definite correlation between follow-up MRI findings and clinical status. Recently, Fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) shows great potential as diagnostic and monitoring options. Simultaneous 18F-FDG PET/MRI makes us to expect a huge synergic effect on diagnosis and evaluation of treatment response with metabolic and anatomical advantages in spine infection. We introduce an application of 18F-FDG PET/MRI for evaluating residual lesion in the patient with pyogenic spine infection.
