Abstract
<p class="Abstract">In the research, nuclear magnetic resonance (NMR) was used to study and diagnose ovarian tumour. A total of 80 ovarian tumour patients who were admitted to the hospital from February 2014 to May 2016 were selected and randomly divided into 2 groups, 40 in the case group and 40 in the control group. The case group used NMR whereas the control group utilized B-mode ultrasound to compare the characteristics of tumor masses, accuracy, sensitivity, and specificity of the clinical diagnosis afterwards. The accuracy, sensitivity, specificity, and characteristics of tumour masses by NMR were 95.84%, 94.75%, 90.92%, and 100%, respectively, which were apparently higher than those of the B-mode ultrasound scanning (64.28%, 77.78%, 75.08%, and 70.83%, respectively). Difference of each index among the four between the two methods was statistically significant (p &lt; 0.05). Therefore, NMR is superior to ultrasound in diagnosing ovarian tumour. </p>
