Abstract：
Background Radial breast ultrasound scanning (r-US) and commonly used meander-like ultrasound scanning (m-US) have recently been shown to be equally sensitive and specific with regard to the detection of breast malignancies. As patient satisfaction has a strong influence on patient compliance and thus on the quality of health care, we compare here the two US scanning techniques with regard to patient comfort during breast ultrasound (BUS) and analyze whether the patient has a preference for either scanning technique. Materials and Methods Symptomatic and asymptomatic women underwent both m-US and r-US scanning by two different examiners. Patient comfort and preference were assessed using a visual analog scale-based (VAS) questionnaire and were compared using a Mann-Whitney U test. Results Analysis of 422 VAS-based questionnaires showed that perceived comfort with r-US (r-VAS 8 cm, IQR [5.3, 9.1]) was significantly higher compared to m-US (m-VAS 5.6 cm, IQR [5.2, 7.4]) (p < 0.001). 53.8% of patients had no preference, 44.3% of patients clearly preferred r-US, whereas only 1.9% of patients preferred m-US. Conclusion: Patients experience a higher level of comfort with r-US and favor r-US over m-US. As the diagnostic accuracy of r-US has been shown to be comparable to that of m-US and the time required for examination is shorter, a switch from m-US to r-US in routine clinical practice might be beneficial. R-US offers considerable potential to positively affect patient compliance but also to save examination time and thus costs.
摘要：
背景技术最近,径向乳房超声扫描(r-US)和常用的蜿蜒型超声扫描(m-US)已经被证明对于乳腺恶性肿瘤的检测具有同等的敏感性和特异性。由于患者满意度对患者依从性有很大影响，从而对医疗保健质量有很大影响，我们在此比较了两种US扫描技术在乳腺超声(BUS)期间的患者舒适度,并分析了患者是否对这两种扫描技术有偏好.材料和方法有症状和无症状的妇女由两名不同的检查者进行了m-US和r-US扫描。使用基于视觉模拟量表（VAS）的问卷评估患者的舒适度和偏好，并使用Mann-WhitneyU检验进行比较。结果422份基于VAS的问卷分析表明，r-US的感知舒适度(r-VAS8cm，IQR[5.3，9.1]）与m-US（m-VAS5.6cm，IQR[5.2,7.4])(p<0.001)。53.8%的患者没有偏好，44.3%的患者明显首选r-US，而只有1.9%的患者首选m-US.结论：患者对r-US的舒适度更高，并且比m-US更喜欢r-US。由于r-US的诊断准确性已被证明与m-US相当，并且检查所需的时间更短，在常规临床实践中从m-US转换为r-US可能是有益的.R-US具有相当大的潜力，可以积极影响患者的依从性，但也可以节省检查时间，从而节省成本。
