目的探讨增强3 D SPACE STIR序列在显示腰骶神经根中的价值。方法对18例腰骶部或盆腔MRI受检者进行常规检查序列、3D SPACE STIR序列平扫和增强扫描。分别计算3D SPACE STIR序列平扫和增强的神经根信噪比值( SNR神经根),肌肉信噪比值( SNR肌肉),神经根和肌肉的对比度噪声比值(CNR神经根/肌肉);将3D SPACE STIR序列平扫和增强的原始图像分别进行MIP重建,最大限度显示腰骶丛神经及其分支,采用4等级评分比较这两个序列对腰骶丛神经解剖的显示情况。结果增强3D SPACE STIR序列神经根的SNR 值和神经根/肌肉的CNR 值均高于平扫序列(分别为115.092±70.946 vs.63.721±23.437,100.610±73.924 vs.51.841±28.649,P<0.05);增强3D SPACE STIR序列对于显示腰丛、骶丛及其分支腰骶干、股神经、坐骨神经、闭孔神经等的评分高于平扫序列(分别为2.611±0.501 vs.1.889±0.323,2.500±0.515 vs.1.722±0.461,2.167±0.618 vs.0.833±0.383,2.222±0.427 vs.1.556±0.511,2.000±0.485 vs.0.833±0.383,0.556±0.616 vs.0.111±0.323,P<0.01)。结论增强3D SPACE STIR序列能清晰地观察腰骶神经丛的解剖形态,能为临床诊治腰骶丛神经病变提供诊断依据。
目的探討增彊3 D SPACE STIR序列在顯示腰骶神經根中的價值。方法對18例腰骶部或盆腔MRI受檢者進行常規檢查序列、3D SPACE STIR序列平掃和增彊掃描。分彆計算3D SPACE STIR序列平掃和增彊的神經根信譟比值( SNR神經根),肌肉信譟比值( SNR肌肉),神經根和肌肉的對比度譟聲比值(CNR神經根/肌肉);將3D SPACE STIR序列平掃和增彊的原始圖像分彆進行MIP重建,最大限度顯示腰骶叢神經及其分支,採用4等級評分比較這兩箇序列對腰骶叢神經解剖的顯示情況。結果增彊3D SPACE STIR序列神經根的SNR 值和神經根/肌肉的CNR 值均高于平掃序列(分彆為115.092±70.946 vs.63.721±23.437,100.610±73.924 vs.51.841±28.649,P<0.05);增彊3D SPACE STIR序列對于顯示腰叢、骶叢及其分支腰骶榦、股神經、坐骨神經、閉孔神經等的評分高于平掃序列(分彆為2.611±0.501 vs.1.889±0.323,2.500±0.515 vs.1.722±0.461,2.167±0.618 vs.0.833±0.383,2.222±0.427 vs.1.556±0.511,2.000±0.485 vs.0.833±0.383,0.556±0.616 vs.0.111±0.323,P<0.01)。結論增彊3D SPACE STIR序列能清晰地觀察腰骶神經叢的解剖形態,能為臨床診治腰骶叢神經病變提供診斷依據。

Objective To investigate the value of enhanced 3D SPACE STIR sequence in displaying lumbosacral plexus .Methods 18 patients had requested to be received lumbosacral or pelvic MRI examinations by unenhanced(3D SPACE STIR scan)and enhanced 3D SPACE STIR scan including routine scan .The SNRnerve root, SNRmuscleand CNRnerve root/muscle were measured in unenhanced and enhanced 3D SPACE STIR sequences .The raw images of unenhanced and enhanced 3D SPACE STIR sequences were processed with 3D MIP separately.The morphology and running of lumbosacral plexus displayed in the two sequcences had been compared by 4 grade scoring system.Results The SNRnerve root values and CNRnerve root/muscle values by enhanced 3D SPACE STIR sequence were all greater than the values by unenhanced sequence (115.092 ±70.946 vs.63.721 ±23.437 ,100.610 ±73.924 vs.51.841 ±28.649,P<0.05).The score of lumbar plexus,sacral plexus and lumbosacral trunk ,femoral nerve,sciatic nerve,obturator nerve shown by enhanced 3D SPACE STIR sequence were higher than unenhanced sequence(2.611 ±0.501 vs.1.889 ±0.323,2.500 ±0.515 vs.1.722 ±0.461,2.167 ±0.618 vs.0.833 ±0.383, 2.222 ±0.427 vs.1.556 ±0.511 ,2.000 ±0.485 vs.0.833 ±0.383 ,0.556 ±0.616 vs.0.111 ±0.323 ,P<0.01 ) . Conclusions The enhanced 3D SPACE STIR sequence could display the anatomy of lumbosacral plexus clearly and play an important role in clinical diagnosis and treatment of the lumbosacral plexus diseases .
