摘要:
目的      分析顽固性血精患者的盆腔核磁共振成像(magnetic resonance imaging,MRI)表现及其影像学特征性改变,探讨MRI在顽固性血精病因诊断中的价值。      方法       回顾性分析76例顽固性血精患者的临床资料,对其盆腔MRI图像进行形态学特征观察,重点分析总结双侧精囊及射精管区域的影像学特征。      结果       与正常男性精道远端区域的MRI特征性影像相比较,76例顽固性血精患者的影像学特征改变主要有:47例表现为精囊区域的特征性信号强度改变,其中23例存在鲜红色血精的患者在T1加权相(T1-weighted images T1WI)精囊呈明显高信号影,在T2加权相(T2-weighted images T2WI)呈明显低信号影,而24例存在咖啡色或巧克力样陈旧性血精的患者在T1WI相和T2WI相均呈中至高等强度信号影;26例显示一侧或双侧精囊呈明显囊性扩张(横径大于1.7 cm),伴或不伴上述精囊内信号强度的特征性改变;21例存在前列腺小囊囊肿;3例存在射精管囊肿;3例存在苗勒氏管囊肿,1例存在精囊囊肿;9例患者精囊区域无明显异常改变。      结论       MRI可有效显示顽固性血精患者精囊、前列腺、射精管区域的精细结构改变,对顽固性血精的病因学诊断及治疗方式的选择具有重要的指导价值。
Abstract:
Objectives      To evaluate the etiological diagnostic value of magnetic resonance imaging (MRI) in persistent and refractory hematospermia by analyzing pelvic MRI manifestations and characteristics.       Methods      The clinical data and morphological features of pelvic MRI images of bilateral seminal vesicles and ejaculatory duct area in 76 patients with persistent and refractory hematospermia were retrospectively analyzed.       Results      In the 76 patients undergoing MRI examination, 47 patients showed the typical changes of signal intensity in seminal vesicle, including 23 patients with fresh hemorrhage showing high signal intensity on T1-weighted images (T1WI) and low signal intensity on T2-weighted images (T2WI), and 24 patients with old hemorrhage showing middle to high signal intensity on both T1WI and T2WI. Twenty-six patients showed significant cystic dilatation of unilateral or bilateral seminal vesicles (the width was greater than 1.7 cm) with or without the internal signal intensity change, 21 patients showed prostatic utricular cysts, 3 patients showed ejaculatory duct cysts, 3 patients showed Mullerian cysts, 1 patient showed the seminal vesicle cyst, and 9 patients did not show any obvious abnormality in seminal vesicle area by comparing with the normal pelvic MRI images of 41 healthy adult men.       Conclusion      Three-dimensional MRI has a good resolution, and can clearly display the pelvic soft tissues and refined structures, such as seminal vesicle, prostate, vas deferens and ejaculatory duct. It has important etiological diagnostic value for patients with persistent and refractory hematospermia.
