主要方法:
- 一组23名患有低精子发生症的患者和93名健康对照 (年龄在20-80岁) 接受了3.0TMRI.
- APTw信号强度 (SI) 和明显扩散系数 (ADC) 值在丸中被测量.
- 分析了数据,以评估与年龄的相关性和群体之间的差异.
主要成果:
- APTw SI显示与年龄有负相关性 (r = -0.510,P < 0.001).
- 表面扩散系数 (ADC) 与年龄呈正相关性 (r = 0.317,P = 0.006).

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

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...
