螺旋CT前列腺灌注成像定性诊断的研究进展

摘要

前列腺良性增生与前列腺癌的血供不同,前列腺癌的微小血管密度比前列腺增生高,微血管通透性较良性增生的前列腺组织多,因而二者的螺旋CT灌注成像动态增强曲线完全不同,并且具有各自的特征.在日常工作中,只要分析应用二者螺旋CT各自灌注成像的特点,就可以为前列腺结节进行定性诊断.%Blood supply varies between benign prostate hyperplasia and prostate caner.Prostate cancer has a higher microvascular density than prostate hyperplasia, in addition to a higher microvascular permeability.Therefore,spiral CT perfusion imaging varies in dynamic enhanced curve.In routine practice,the analysis of spiral CT perfusion imaging helps to qualitatively diagnose prostate nodules.
