SPGR

基本解释

The sequence of SPGR can enhance T1 contrast degree and effect of contrast medium (gadolinium) .
SPGR可以突出T1对比度，能加强顺磁性造影剂（如钆类造影剂）的作用。
The acquisition time of 3D FS SPGR sequence was 4 minutes 55 seconds,the sensitivity,specificity and accuracy of which were 92%,86%,90%.
3DFS SPGR序列扫描时间为 4分 5 5秒 ,其诊断髌股关节软骨病变的敏感性、特异性和总符合率为 92%25、86%25和90%25。
There were only 82 lesions on SPGR T1WI sequence and 106 lesions on FSE T2WI sequence with suppression which were detected by pre-contrast MRI.
Resovist增强T2*共检出127个病灶；平扫SPGR序列检出病灶最少，仅82个；
Following intravenous bolus injection of 0.2mmol/kg Gd-DTPA, coronal SPGR images of 24 slices was gained within 27 seconds.
再重复同样扫描，分别获得早期相与后期相。
Results:On the pre- and postcontrast FMP SPGR T 1WI the mean signal intensity of fatty livers was lower than the normal livers,but there was no significant difference among different grades of fatty livers (P>0.05).
增强后信号绝对值较对照组低 ;差异有极显著性意义 (P 0
