Diagnostic value and clinical significance of MRI and CT in detecting lymph node metastasis of early cervical cancer

Diagnostic value and clinical significance of magnetic resonance imaging (MRI) and computed tomography (CT) in detecting lymph node metastasis of early cervical cancer were investigated. From April 2015 to April 2019, 160 patients with lymph node metastasis (stage I–II) of early cervical cancer in Jining No. 1 People's Hospital were retrospectively analyzed. All the patients underwent MRI, CT diagnosis and MRI combined with CT diagnosis before operation. Sensitivity, specificity and diagnostic accordance rate, the diagnostic value and clinical significance of MRI, CT and MRI combined with CT in the diagnosis of lymph node metastasis of early cervical cancer were compared. The sensitivity, specificity and diagnostic accordance rate of MRI in the diagnosis of lymph node metastasis of early cervical cancer in stage Ia-Ib were 75.00, 72.92 and 77.50%, respectively, which were significantly higher than those of PET/CT in the same period (P<0.05). The sensitivity, specificity and diagnostic accordance rate of MRI combined with CT in the diagnosis of early cervical cancer in stage Ia-Ib were 78.13, 87.50 and 83.75%, respectively, which were significantly higher than those of MRI or CT alone (P<0.05). However, the sensitivity, specificity and diagnostic accordance rate of MRI combined with CT in the diagnosis of lymph node metastasis of early cervical cancer in stage IIa-IIb were 91.66, 82.81 and 88.13%, respectively, which were significantly higher than those of MRI or CT alone (P<0.05). MRI is superior to CT in the diagnosis of lymph node metastasis of early cervical cancer. However, the diagnostic efficiency of combined scans of the two is far higher than that of MRI or CT alone, which has more diagnostic value. In clinic, MRI and CT should be combined to improve the diagnostic accuracy of diseases.
