SPGR

基本解釋

The sequence of SPGR can enhance T1 contrast degree and effect of contrast medium (gadolinium) .
SPGR可以突出T1對(duì)比度，能加強(qiáng)順磁性造影劑（如釓類造影劑）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序列掃描時(shí)間爲(wèi) 4分 5 5秒 ,其診斷髕股關(guān)節(jié)軟骨病變的敏感性、特異性和縂符郃率爲(wèi) 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增強(qiáng)T2*共檢出127個(gè)病灶；平掃SPGR序列檢出病灶最少，僅82個(gè)；
Following intravenous bolus injection of 0.2mmol/kg Gd-DTPA, coronal SPGR images of 24 slices was gained within 27 seconds.
再重複同樣掃描，分別獲得早期相與後期相。
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).
增強(qiáng)後信號(hào)絕對(duì)值較對(duì)照組低 ;差異有極顯著性意義 (P 0
