Abstract
Purpose
To investigate the fusion of pelvic magnetic resonance imaging (MRI) and fluorodeoxyglucose
positron emission tomography (PET) for assessment of locoregional extension and nodal
staging of cervical cancer.
Methods
PET/computed tomography (CT), MRI, and non-fused and fusion of PET and MRI for assessing
the extent of the primary tumor and metastasis to nodes were evaluated.
Results
Accuracy for T-status was 83.3% for fused and non-fused PET/MRI and MRI proved significantly
more accurate than PET/CT (53.3%) (P=.0077). Sensitivity, specificity, and accuracy for nodal metastasis were 92.3%, 88.2%,
and 90.0% for fused PET/MRI and PET/contrast-enhanced CT; 84.6%, 94.1%, and 90.0%
for non-fused PET/MRI; and 69.2%, 100%, and 86.7% for MRI.
Conclusion
Fused PET/MRI combines the individual advantages of MRI and PET.
