【摘要】：目的探討MR超快速成像序列評(píng)估正常胎兒腎臟的可行性。方法收集135胎腎臟發(fā)育正常胎兒的MR資料,測(cè)量腎臟長(zhǎng)度(RL)、寬度(RW)、厚度(RT)、腎實(shí)質(zhì)厚度(RPT)、腎盂寬度(RPW)和體積(RV),分析上述參數(shù)測(cè)量的重復(fù)性及其與胎齡(GA)的關(guān)系。結(jié)果RL、RW、RT、RPT、RPW在2名觀察者間、同一觀察者2次測(cè)量間、MR與超聲兩種測(cè)量方法間均具有較好的一致性,各參數(shù)測(cè)量值在雙側(cè)腎臟間差異無(wú)統(tǒng)計(jì)學(xué)意義(P均0.05)。RL、RW、RT、RPT、RPW、RV與GA均呈正相關(guān)(r分別為0.95,0.87,0.86,0.77,0.44,0.90,P均0.001)。在各參數(shù)與GA的回歸方程中,RL的確定系數(shù)最大(R~2=0.90)。結(jié)論 MR超快速成像序列用于正常胎兒腎臟檢查中具有可行性,可彌補(bǔ)超聲檢查的不足,為臨床決策提供更多有價(jià)值的影像學(xué)信息。
[Abstract]:Objective to evaluate the feasibility of Mr ultrafast imaging in the evaluation of normal fetal kidney. Methods the MRI data of 135 fetuses with normal kidney development were collected. The length of kidney, the width of RWN, the thickness of RTT, the thickness of renal parenchyma (RPTT), the width of renal pelvis (RPWW) and the volume of RV were measured. The repeatability of these parameters and their relationship with gestational age (GA) were analyzed. Results there was a good agreement between two observers, two measurements of Mr and two methods of ultrasound. There was no significant difference in the values of each parameter between the two kidneys (P > 0.05). RV and GA were positively correlated with the RV and GA, respectively. The mean values of RV and GA were 0. 05%, 0. 770%, 0. 74% and 0. 90% (P = 0. 001), respectively. In the regression equation of each parameter and GA, the determinate coefficient of RL is the highest (R ~ (2) ~ (2)) ~ (0.90) ~ (-1). Conclusion it is feasible to use Mr ultrafast imaging sequence in normal fetal kidney examination, which can make up for the deficiency of ultrasound examination and provide more valuable imaging information for clinical decision-making.
