目的研究磁共振(MRI)弥散张量成像对于前列腺癌和良性前列腺增生的诊断价值。方法前列腺癌、良性前列腺增生患者各30例作为研究对象,均进行MRI弥散张量成像,比较两种疾病的各项异性值(FA)和平均表观弥散系数(ADC)的变化。结果前列腺癌患者的FA高于良性前列腺增生患者,ADC低于良性前列腺增生患者(P<0.05)。结论 MRI弥散张量成像能够明确地显示前列腺组织的微观组织结构,可以为前列腺癌和良性前列腺增生提供明确的诊断信息,在前列腺疾病诊断中拥有临床价值。
Objective To study the diagnostic value of magnetic resonance (MRI) diffusion tensor imaging in prostate cancer and benign prostatic hyperplasia. Methods Thirty patients with prostate cancer and benign prostatic hyperplasia were studied by MRI diffusion tensor imaging. The anisotropy (FA) and mean apparent diffusion coefficient (ADC) of the two diseases were compared. Results The FA of prostate cancer patients was higher than that of benign prostatic hyperplasia patients, and the ADC was lower than that of benign prostatic hyperplasia patients (P <0.05). Conclusion MRI diffusion tensor imaging can clearly show the microstructure of prostate tissue, which can provide definite diagnostic information for prostate cancer and benign prostatic hyperplasia, and has clinical value in the diagnosis of prostatic diseases.
