目的本研究的目的是定量评估脂肪沉积在睾丸和附睾的脂肪/水的信号比测量与mDIXON Quant，并探讨其与年龄和exaculation.Materials和方法的相关性常规盆腔磁共振成像和mDIXON Quant进行了120例受试者。根据mDIXON Quant上的脂肪/水信号强度测量睾丸和附睾的脂肪/水信号比。0.952- 3.550%，p < 0.05; 5.182- 12.725%，p < 0.05，儿童期晚期组与对照组相比，（0.611-2.198%和1.310-4.520%）和青年组（0.659-2.360%和1.568-4.469%），均低于中年组（1.538- 4.249%和5.830- 19.002%）（p < 0.05）。每月射精十次以上的青年组睾丸脂肪沉积减少（0.750- 2.022%，p < 0.05），并且在成年早期组中的一名受试者中，12小时内有三次射精，附睾的脂肪/水信号比降低。以及评价睾丸和附睾脂肪沉积的客观方法。该方法可为不同年龄组、不同射精经历者的睾丸和附睾脂肪沉积提供指导。此外，我们的研究结果可能有助于更准确的诊断和监测睾丸和附睾的生殖功能，通过定量测量他们的脂肪沉积与年龄。
PurposeThe objective of this study was to quantitatively assess fat deposition in the testis and epididymis by measuring the fat/water signal ratios with mDIXON Quant and to investigate its correlation with age and ejaculation.Materials and methodsRoutine pelvic magnetic resonance imaging and mDIXON Quant were performed on 120 subjects. The fat/water signal ratios of the testis and epididymis were measured based on the fat/water signal intensity on mDIXON Quant.ResultsThe fat/water signal ratio values of the testis and epididymis in the early adulthood group (0.952–3.550%,p< 0.05, and 5.182–12.725%,p< 0.05, respectively) were significantly higher than those in the late childhood group (0.611–2.198% and 1.310–4.520%) and in the youth group (0.659–2.360% and 1.568–4.469%), and they were lower than those in the middle adulthood group (1.538–4.249%,p< 0.05, and 5.830–19.002%,p< 0.05). The fat deposition decreased in the testis of the youth group, who ejaculated more than ten times per month (0.750–2.022%,p< 0.05), and the fat/water signal ratios of the epididymis decreased in one subject in the early adulthood group who had three ejaculations within 12 h.ConclusionThe findings of this study suggest that mDIXON Quant may be useful as a noninvasive, quantitative, and objective method for evaluating the fat deposition of the testis and epididymis. This method can provide guidance for fat deposition in the testis and epididymis in different age groups with varying ejaculation experiences. Additionally, our findings may facilitate more accurate diagnosis and monitoring of the reproductive function of the testis and epididymis by quantitatively measuring their fat deposition with age.
