AI总结：
本研究提出采用脉冲波多普勒超声评估前列腺放疗患者双侧神经血管束功能，并提取五项血流波形指标，为实施保留神经血管束的放疗、减少勃起功能障碍提供依据。
摘要：
本研究旨在使用脉冲波多普勒超声评估接受前列腺放疗（RT）患者双侧神经血管束（NVB）的功能状态。62例患者（平均年龄：66.1±7.2岁）使用常规超声扫描仪、7.5 MHz双平面探头和机械步进器接受经直肠超声扫描。超声方案包括3个步骤：1）对整个前列腺进行3D B型扫描，2）使用彩色血流多普勒成像定位NVB，3）使用脉冲波多普勒测量NVB功能。提取了5项脉冲多普勒波形特征：收缩期峰值流速（PSV）、舒张末期流速（EDV）、平均流速（Vm）、阻力指数（RI）和搏动指数（PI）。总之，本研究对接受前列腺RT患者的NVB进行了多普勒评估，强调了双侧NVB之间在多普勒超声波形特征上存在显著差异。当临床医生努力实施保留NVB的RT以有效保护性功能并提升患者整体福祉时，所提出的超声方法可能具有重要价值。
英文摘要：
This study aims to evaluate the functional status of bilateral neurovascular bundles (NVBs) using pulsed wave Doppler ultrasound in patients undergoing prostate radiotherapy (RT). Sixty-two patients (mean age: 66.1 +/- 7.2 years) underwent transrectal ultrasound scan using a conventional ultrasound scanner, a 7.5 MHz bi-plane probe and a mechanical stepper. The ultrasound protocol comprised 3 steps: 1) 3D B-mode scans of the entire prostate, 2) localization of NVBs using color flow Doppler imaging, and 3) measurement of NVB function using pulsed wave Doppler. Five pulsed Doppler waveform features were extracted: peak systolic velocity (PSV), end-diastolic velocity (EDV), mean velocity (Vm), resistive index (RI), and pulsatile index (PI). In summary, this study presents a Doppler evaluation of NVBs in patients undergoing prostate RT. It highlights substantial differences in Doppler ultrasound waveform features between bilateral NVBs. The proposed ultrasound method may prove valuable as clinicians strive to deliver NVB-sparing RT to preserve sexual function effectively and enhance patients' overall well-being.
