Myocardium at risk in ST-elevation myocardial infarction: comparison of T2-weighted edema imaging with the endocardial surface area assessed by magnetic resonance and validation against angiographic scoring
Results The AAR assessed by T2-weighted imaging showed a good correlation with the angiographic AAR (r=0.87; p<0.001), whereas the ESA showed only a moderate correlation either to T2-weighted imaging (r=0.56; p<0.001) and the APPROACH-Score (r=0.44; p<0.001). Mean AAR by ESA (20.0±11.7%LV) was significantly smaller than AAR by T2-weighted imaging and APPROACHScore (p<0.001 respectively) and sho...
متن کاملComparison between transmural and non-transmural infarction and the area at risk using T2 weighted imaging
Methods The study population consisted of 20 patients with acute ST-elevation myocardial infarction treated by primary PCI. Cardiac MRI was performed within 10 days. The infarct size and the transmural extent of infarction (TEI) and mean TEI was quantified on delayed-enhancement images using 36 segments for each slices. AAR was quantified on T2-weighted images. Transmural infarction was defined...
متن کاملCardiac and Hepatic T2*-Weighted Magnetic Resonance Imaging
Abstract Background Iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. Severe iron deposition in tissues leads to organ dysfunction. Many organs can be affected such as heart, liver, and endocrine organs. Cardiac failure and liver fibrosis are the consequent of Iron overload in transfusion dependent hemoglobinopathy. Magne...
متن کاملMyocardial Edema on T2-Weighted MRI
Importance of Evaluation of Ischemia/ Reperfusion Injury by Magnetic Resonance Imaging Although the advances in revascularization therapy have drastically decreased the mortality after ST-segment–elevation myocardial infarction (STEMI), the number of patients who develop heart failure after the reperfusion therapy continues to increase. More than 30% of the patients who survive STEMI develop he...
متن کاملComparison of diffusion-weighted with T2-weighted imaging for detection of edema in acute myocardial infarction
BACKGROUND Recent studies, performed with the use of a commercially available diffusion weighted imaging (DWI) sequence, showed that they are sensitive to the increase of water content in the myocardium and may be used as an alternative to the standard T2-weighted sequences. The aim of this study was to compare two methods of myocardial edema imaging: DWI and T2-TIRM. METHODS The study includ...
