概括

从扩散权重的MRI中获得的明显扩散系数 (ADC) 值可靠地将非触摸的未下降丸与淋巴结区分开来. 这种新的成像技术有助于精确地定位丸,当传统方法不足时.

科学领域:

放射学放射学是一门学科.
儿科手术儿科手术
医疗成像医学成像

背景情况:

未下降的丸 (UT) 影响了20%的病例,通常需要成像以定位.
放射性成像对于识别腹部或关节的非触摸性尿道术至关重要.
之前的研究探讨了扩散权重磁共振成像 (DWI) 用于UT检测,但没有明显扩散系数 (ADC) 值用于组织分化.

研究的目的:

调查ADC值在非触摸性尿道中区分丸组织与淋巴结 (LNs) 的有用性.
评估DWI衍生ADC值的诊断性能,用于定位未下降的丸.
建立一个定量成像生物标志物来区分丸组织.

主要方法:

在儿童患者中使用DWI成像,怀疑UTS.
在丸和淋巴结 (LN) 组织中测量ADC值.
在组织中心使用一个有趣的圆形区域进行ADC测量.

主要成果:

分析了44名男孩和73个丸;年龄和丸体积之间有显著的正相关性 (p < 0.001).
与阴囊丸相比,丸ADC值在 inguinal和腹部位置较高.
临床瘤的ADC值明显低于丸的ADC值,ADC值<940 x 10^-3/mm^2区分丸与临床瘤 (AUC = 0.826,p < 0.001).

结论:

使用DWI序列的ADC测量准确地区分丸组织与LNs.
ADC映射是一种新的,可靠的工具,用于定位不可触摸的未下降丸.
这种方法提高了诊断准确度,当标准评估不足时.

关键词:

Testes: Gross Anatomy

Testes: Gross Anatomy

The testes, also known as testicles, are the male gonads. They are housed within the scrotum, a sac-like structure located beneath the penis. The scrotum's primary role is to regulate the temperature of the testes, which is crucial for sperm production.
Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...
