摘要 目的分析不同年龄正常男性前列腺大小及前列腺外周带磁共振成像(MRI)信号强度和年龄相关性,以及精囊腺大小和MRI信号强度与年龄的相关性。方法 52例正常成人,根据年龄不同分为4组(21~30岁,31~40岁,41~50岁,50岁以上),测量前列腺外周带和中央腺的前后径、左右径、T2WI信号强度和闭孔内肌信号强度,计算外周带和中央腺与闭孔内肌相比的相对信号强度,并测量精囊腺横径及T2WI信号强度。结果前列腺外周带和中央腺的前后径及左右径、T2WI信号强度,相对信号强度各年龄组间差异有统计学意义(P<0.05)。前列腺外周带前后径、左右径及T2WI信号强度与年龄之间均呈正相关(r=0.543、P<0.01,r=0.538、P<0.01),但外周带T2WI信号强度与年龄呈正相关关系(r=0.332,P<0.05)。而不同年龄组精囊腺横径及T2WI信号强度各组间差异无统计学意义(P>0.05)。结论前列腺大小及T2WI信号强度与年龄相关,并随年龄增长各值逐渐增大。
