[Comparison of an @entity4 -sensitive HASTE-TIRM sequence with delayed contrast enhancement in acute XXXX ].

@entity1 @entity4 @entity908 @entity1188 @entity583
GOAL: Comparison between a fluid-sensitive (HASTE-TIRM)-sequence and delayed contrast-enhancement in @entity1 with @entity583 ( @entity583 ) in MRI. MATERIAL AND METHODS: 32 @entity1 with @entity583 were imaged 7 +/- 4 days after the time of @entity1188 with a 1.5 T unit using a T2 HASTE-TIRM and a contrast-enhanced (CE) T1 turbo FLASH sequence. A threshold method (>2 SD in comparison with normal myocardium) was used to quantify the hyperintense zones in both sequences. The transmurality of the hyperintense regions was measured on a segmental basis. RESULTS: The hyperintense areas were larger on the HASTE-TIRM sequence with 29.6 +/- 13.2 % of the left ventricular (LV) area as compared to the CE-MRI with 19.2 +/- 10 % of the LV area (p < 0.0001). The measured transmurality was higher with the HASTE-TIRM sequence than with the CE-MRI (p < 0.0001). While the correlation between CE-MRI and peak @entity908 kinase (CK max) was good (r = 0.59, p < 0.001), no correlation was found between the HASTE-TIRM sequence and CK max (r = 0.29, p = ns). CONCLUSIONS: The peri- @entity1188 @entity4 can be depicted with a HASTE-TIRM sequence in addition to the non-viable @entity1188 zone. The HASTE-TIRM sequence shows a higher transmurality of the hyperintense regions than the CE-MRI. The additional area depicted by the HASTE-TIRM sequence could represent functionally impaired but viable myocardium).
