高分辨磁共振多参数、多方位、多序列成像技术在隐匿性阴茎诊断中应用价值的初步研究

Preliminary study on the diagnostic value of high-resolution magnetic resonance imaging technology with multi-parameter,multi-azimuth and multi-sequence in concealed penis

目的探讨高分辨磁共振多参数、多方位、多序列成像技术在隐匿性阴茎中的应用价值.方法对宁波大学附属第一医院2018年10月—2022年5月期间临床上确诊为隐匿性阴茎患者30名,对30名患者行高分辨磁共振多参数、多方位、多序列检查.检查结果以阴阜与外部阴茎垂直切面为分割点.分割点至阴茎头的距离为外部阴茎的长度;分割点至尿道海绵体球部后缘的距离为内部阴茎的长度.分别测量外部阴茎与内部阴茎的长度,计算其比值;统计比值区间人数及占总数的百分比,同临床不同体检结果组比较.结果内部阴茎与外部阴茎比值为1<r≤2区间1人、2<r≤3区间12人、3<r≤4区间11人、4<r≤5区间4人、5<r≤6区间1人、6<r≤7区间1人;占总人数百分比分别为3.33%、40.00%、36.67%、13.34%、3.33%、3.33%.结论高分辨磁共振多参数、多方位、多序列成像技术在隐匿性阴茎中的应用可以直观地观察和测量外部阴茎和内部阴茎的长度,为隐匿性阴茎患者在临床的治疗提供可靠、准确的影像依据;对隐匿性阴茎患者的术后评价同样具有一定参考价值.

Objective To explore the diagnostic value of high-resolution magnetic resonance imaging technology with multi parameter,multi orientation and multi sequence in concealed penis.Methods Total of 30 patients with concealed penis diagnosed clinically in Ningbo University Affiliated First Hospital from October 2018 to May 2022 were examined by high-resolution magnetic resonance imaging with multi parameter,multi orientation and multi sequence.The vertical section between the pubic caruncle and the external penis was taken as the segmentation point.The length of the external penis was defined as the distance from the dividing point to the glans,and the length of the internal penis as the distance from the dividing point to the posterior edge of the urethral cavernous bulb.The lengths of external penis and internal penis were respectively measured,and their ratio was calculated;The number of patients in the ratio interval and the percentage in the total were compared with different clinical sign groups.Results The ratio of internal penis to external was in the range of 1<r≤2 for 1 patient,in the range of 2<r≤3 for 12 patients,in the range of 3<r≤4 for 11 patients,in the range of 4<r≤5 for 4 patients,in the range of 5<r≤6 for 1 patient,in the range of 6<r≤7 for 1 patient;The percentages in the total number of patients were 3.33%,40.00%,36.67%,13.34%,3.33%and 3.33%respectively.Conclusion The application of highresolution magnetic resonance imaging technology with multi parameter,multi orientation and multi sequence in occult penis can provide reliable and accurate image basis for the treatment of patients with occult penis by directly measuring the length of external penis and internal penis.The evaluation of concealed penis is also of great reference value for patients after operation.
