目的探讨1.5T磁共振在良性前列腺增生(BPH)与前列腺癌(PC)中的诊断价值。材料与方法选取经过病理证实的40例前列腺病变患者,其中BPH27例,PC13例,观察上述前列腺病变的位置、信号特点及组织代谢特征等方面加以分析。结果 27例BPH前列腺显示不同程度增大,19例伴增生结节,15例伴慢性前列腺炎。13例PC外围叶内见低信号影,DWI呈明显扩散受限,MRS显示Cho峰显著升高,Cit峰下降或消失。结论 1.5T磁共振成像对前列腺病变有一定特征性,多种成像技术综合应用,对BPH及PC的鉴别诊断价值较大。
Objective To investigate the diagnostic value of 1.5T MRI in benign prostatic hyperplasia (BPH) and prostate cancer (PC). Materials and Methods Forty patients with pathologically confirmed prostate disease were selected, including 27 cases of BPH and 13 cases of PC, and their location, signal characteristics and tissue metabolic characteristics were observed. Results 27 cases of BPH prostate showed varying degrees of increase, 19 cases with proliferative nodules, 15 cases with chronic prostatitis. 13 cases of PC peripheral lobe see low signal, DWI was significantly limited diffusion, MRS showed Cho peak was significantly increased, Cit peak decreased or disappeared. Conclusion 1.5T magnetic resonance imaging of prostate lesions have some characteristics, a variety of imaging techniques integrated application of BPH and PC differential diagnosis of greater value.
