【摘要】：目的对比分析良性前列腺增生(BPH)区及正常前列腺周围带(PZ)在多回波采集重度T_2~*加权三维梯度回波(ESWAN)序列上成像的特征,探讨多指标ESWAN评估BPH的可行性。方法对病理证实的48例BPH患者行ESWAN扫描,分别测量BPH和PZ的R_2~*值、T_2~*值、相位值及磁矩值,比较BPH和PZ、尿潴留组(15例)和非尿潴留组(23例)增生区ESWAN指标的差异。结果 BPH的R_2~*值、T_2~*值及磁矩值分别为20.16±3.04、50.41±8.53、1559.88±261.10,正常周围带的相应各值分别为16.15±8.45、80.96±56.86、1505.53±252.48;BPH的R_2~*值PZ(P=0.006),T_2~*值PZ(P=0.000),而磁矩值PZ(P=0.023)。BPH的相位值PZ,但两者差异不具统计学意义(P=0.294)。尿潴留组增生区R_2~*值(20.61±2.47)大于非尿潴留组(18.73±2.81),且差异具有统计学意义(P=0.037);尿潴留组增生区T_2~*值(50.13±4.85)小于非尿潴留组(56.88±8.63),差异亦存在统计学意义(P=0.009)。两组相位值及磁矩值差异均不具有统计学意义(P0.05)。结论 BPH与正常周围带在ESWAN上具有各自的特征性,R_2~*、T_2~*值对BPH合并尿潴留有临床诊断价值,有助于进一步扩展ESWAN在前列腺疾病中的应用。
[Abstract]:Objective to compare and analyze the imaging features of benign prostatic hyperplasia (BPH) region and normal periprostatic zone (PZs) on multiple echo acquisition of severe T _ 2T _ 2 * weighted three-dimensional gradient echo (ESWAN) sequence. Methods 48 patients with pathologically proved BPH were examined by ESWAN and the R2S of BPH and PZ were measured respectively. Phase value and magnetic moment were compared between BPH and PZ, 15 cases of urinary retention group (15 cases) and 23 cases of non-urinary retention group (23 cases). The value of T _ 2O _ (*) and magnetic moment were 20.16 卤3.04 ~ 50.41 卤8.53 ~ 1 59.88 卤261.10, respectively. The corresponding values of the normal peripheral zone were 16.15 卤8.45 ~ 80.96 卤56.86 ~ 1505.53 卤252.48; The R2T value of BPH is 0.006 and the phase value of magnetic moment value PZ(P=0.023).BPH is PZ. However, there was no significant difference between the two groups (P < 0. 294). The value of R2P in proliferative area of urinary retention group was 20.61 卤2.47, which was higher than that in non-urinary retention group (18.73 卤2.81). The difference was statistically significant (P < 0.037). In the hyperplastic area of urinary retention group, the value of T _ 2O ~ * was 50.13 卤4.85 and 56.88 卤8.63). The difference was also statistically significant (P 0.05). The phase and magnetic moment values of the two groups were not statistically significant (P 0.05). Conclusion BPH and normal peripheral zone have their own characteristics on ESWAN. The value of R2C2T * has clinical value in the diagnosis of BPH with urinary retention, which is helpful to further expand the application of ESWAN in prostate diseases.
