Comparison of the validity of magnetic resonance imaging and positron emission tomography/computed tomography in the preoperative evaluation of patients with uterine corpus cancer

摘要: Abstract Objective. To compare positron emission tomography/computed tomography (PET/CT) with magnetic resonance imaging (MRI) in the preoperative detection of primary lesions and lymph node (LN) distant metastases patients uterine corpus cancer. Methods. The patient cohort consisted 53 women cancer who underwent workup, including both MRI PET/CT scans, surgical staging, pelvic and/or paraaortic LN dissection, between October 2004 June 2007 at Asan Medical Center, Seoul, Korea. Pathologic data from staging were compared results. For area specific analysis, LNs divided into paraaortic, right left areas. Results. In detecting lesions, showed no differences sensitivity (91.5% vs. 89.4%), specificity (33.3% 50.5%), accuracy (84.9% 84.9%), positive predictive value (PPV) 93.3%) negative (NPV) 37.5%). With MRI, sensitivity, specificity, accuracy, PPV NPV for metastatic on area-by-area analysis 46.2%, 87.9%, 83.9%, 28.6% 94.0%, respectively; PET/CT, those 69.2%, 90.3%, 88.3%, 42.9%, 96.6%, respectively. higher but it did not reach statistical significance ( p =0.250). There also NPV. metastasis, 100%, 93.8%, 92.5%, 62.5% Conclusion. cancer, had moderate metastases, indicating that this method cannot replace staging. benefit is its metastases. Because high predicting may have advantages selected are poor candidates
