PURPOSE
To compare the diagnostic accuracy of PET+MR with PET/CT in the initial staging of head and neck cancer.
MATERIALS AND METHODS
Contrast-enhanced PET/CT+MR was performed in 27 patients with newly diagnosed head and neck cancer. PET/CT and PET+MR were evaluated separately, and the TNM stage and factors influencing treatment were assessed.
RESULTS
The TNM staging by PET+MR was comparable to PET/CT (T: p=0.331, N: p=0.453, M: p=0.034). The sensitivity/specificity/accuracy of treatment-influencing factors by PET/CT and PET+MR were 0.68/0.99/0.97, and 1.00/1.00/0.99, respectively.
CONCLUSIONS
Whole-body staging with PET+MR yields at least equal diagnostic accuracy as PET/CT in head and neck cancer.
目的
比较PET+MR与PET/CT对头颈部癌进行初始分期时的诊断准确性。
材料与方法
对27例新诊断的头颈部癌患者进行增强PET/CT+MR检查。分别对PET/CT和PET+MR进行评估，并评估TNM分期及影响治疗的因素。
结果
PET+MR的TNM分期与PET/CT相当（T：p=0.331，N：p=0.453，M：p=0.034）。PET/CT和PET+MR对影响治疗因素的敏感性/特异性/准确性分别为0.68/0.99/0.97和1.00/1.00/0.99。
结论
在头颈部癌中，PET+MR全身分期的诊断准确性至少与PET/CT相当。
