Study on the diagnostic value of 3.0 T endovaginal coil magnetic resonance imaging technique for early cervical cancer

Objective To evaluate the diagnostic value of 3.0 T endovaginal coil magnetic resonance imaging technique for early cervical cancer. Methods Forty patients with early cervical cancer admitted to the gynecology department of the hospital were selected, and each patient underwent pelvic magnetic resonance scanning with external array coil and intravaginal coil, respectively. The imaging quality scores of the two coil images were analyzed and compared by two radiologist with double-blind method, and the accuracy of preoperative pathological staging of early cervical cancer (stage Ia1-Ib1) was compared between the two groups with postoperative pathological results as the gold standard. Results The image quality score of the endovaginal coil group was significantly higher than that of the external array coil group, and the difference was statistically significant ( t = −2.85, p < 0.05). Taking the postoperative pathological results as the gold standard, the accuracy of pathological diagnosis of early cervical cancer (stage Ia1-Ib1) in the endovaginal coil group was 82.5 and 37.5% in the external array coil group. The difference was statistically significant (x 2 = 4.56, p = 0.027 < 0.05). Conclusion 3.0 T magnetic resonance combined with endovaginal coil is better than external array coil in the imaging diagnosis of early cervical cancer, and can more accurately diagnose cervical cancer.
