Early post-operative magnetic resonance imaging in XXXX : correlation among radiological findings and overall survival in 60 @entity1 .

@entity1 @entity5 @entity1188 @entity7441 @entity463
OBJECTIVES: To evaluate @entity7441 ( @entity7441 ) as a prognostic tool after resection of @entity463 . METHODS: Sixty @entity7441 examinations were evaluated for perioperative @entity1188 , @entity5 growth between diagnosis and @entity7441 , contrast enhancement pattern, and extent of resection (EOR). The EOR was approached with the subjective evaluation of radiologists and by quantifying volumes. These parameters were tested as predictors of survival using the Kaplan-Meier method. RESULTS: Contrast enhancement was found in 59 @entity1 (59/60; 98  %). Showing a thin-linear pattern of enhancement was the most favourable finding. @entity1 with this pattern survived longer than @entity1 with thick-linear (median overall survival (OS) thin-linear=609  days; thick-linear=432  days; P   =   .023) or nodular (median OS   =   318  days; P   =   .001) enhancements. The subjective evaluation of the EOR performed better than its quantification. @entity1 survived longer when resection was total (median OS total resection=609  days; subtotal=371  days; P   =   .001). When resection was subtotal, @entity1 survived longer if it was superior to 95  % (median OS resection superior to 95  %=559  days; inferior to 95  %=256  days; P   =   .034). CONCLUSIONS: @entity7441 provides valuable prognostic information after surgical resection of @entity463 . A thin-linear pattern of contrast enhancement is the most favourable finding. Further prognostic stratification may be obtained by assessing the EOR. KEY POINTS:     Some kind of contrast enhancement may be found in most @entity7441 examinations.     Thin-linear enhancements in the @entity7441 may be considered benign findings.     The EOR evaluated in the @entity7441 may stratify prognostic groups of @entity1 .     The subjective evaluation of the EOR performs slightly better than its quantification.
