Abstract:
Objective To compare the diagnostic efficacy of biparametric magnetic resonance imaging(bp-MRI)and multiparametric magnetic resonance imaging(mp-MRI)for prostate cancer among radiologists with different levels of experience.Methods A retrospective analysis was conducted on MRI data of 112 suspected prostate cancer patients.Six radiologists(2 in the primary,intermediate,and advanced groups)used the bp-MRI and mp-MRI protocol scores to analyze the diagnostic efficacy.Results The area under the curve(AUC)of diagnostic efficacy in the advanced group of the bp-MRI protocol was greater than that in the intermediate group(P=0.024),and the intermediate group was greater than that in the primary group(P=0.046).The intermediate group of the mp-MRI protocol was greater than the primary group(P=0.043),while there was no difference between the intermediate and advanced groups(P=0.221).As the experience of the radiologists increased,sensitivity also increased,but there was no significant change in specificity.There was no difference between the two protocols in the advanced group(AUC=0.826-0.866;P＞0.05);while the mp-MRI protocol performance was better in the primary and intermediate groups(AUC=0.705-0.815;P＜0.05).Conclusion Experienced radiologists can choose the bp-MRI protocol,while inexperienced radiologists are more suitable for the mp-MRI protocol.Based on the accumulated experience of radiologists,protocol optimization and adjustment can be carried out at appropriate times.
