Comparison of T1-mapping and T2-weighted imaging for diagnostic oedema assessment in ST-segment elevation myocardial infarction
نویسندگان
چکیده
Background Myocardial oedema (area-at-risk, AAR) is typically imaged using a pre-contrast T2-weighted short tau inversion recovery (T2w-STIR) sequence on cardiovascular magnetic resonance (CMR) imaging. However, this sequence is prone to motion and rhythm artefact, signal dropout, blood-pool artefact, surface coil signal inhomogeneity and potentially prohibitive long breath-hold duration. This susceptibility to artefacts limits utility of T2w-STIR in large clinical trials where attainment of diagnostic quality oedema imaging in the majority is necessary to determine myocardial salvage: a measure of reperfusion success and a strong predictor of adverse remodeling and prognosis post ST-segment elevation myocardial infarction (STEMI). We compare AAR quantified on T2w-STIR imaging with novel T1-mapping on 3.0T CMR post STEMI.

BACKGROUND Patients with recent non-ST-segment elevation myocardial infarction commonly have heterogeneous characteristics that may be challenging to assess clinically. METHODS AND RESULTS We prospectively studied the diagnostic accuracy of 2 novel (T1, T2 mapping) and 1 established (T2-weighted short tau inversion recovery [T2W-STIR]) magnetic resonance imaging methods for imaging the ischem...

Methods Eight male patients with acute ST-elevation myocardial infarction underwent CMR at 3T (Siemens Verio) acutely and after >3 months. Imaging techniques included: T2-weighted imaging, late enhancement (LGE) as well as T2-mapping (3 single-shot SSFP-images), native T1-mapping (MOLLI, 11 single-shot SSFPimages), and T1-mapping 10min after 0.2mmol gadobutrol using non-product sequences.

BACKGROUND CMR T1 mapping is a quantitative imaging technique allowing the assessment of myocardial injury early after ST-segment-elevation myocardial infarction. We sought to investigate the ability of acute native T1 mapping to differentiate reversible and irreversible myocardial injury and its predictive value for left ventricular remodeling.

متن کاملT1 and T2 Mapping have a higher diagnostic accuracy for the ischaemic area-at-risk in NSTEMI patients compared with dark blood imaging
Background T1 and T2 mapping has shown great promise for the identification of acute myocardial infarction. However, most of this work has been performed in patients with ST-elevation myocardial infarction (STEMI). We prospectively studied the diagnostic accuracy of two novel (T1, T2 mapping) and one established (T2 STIR) MRI methods for imaging the ischaemic area-at-risk (AAR) in patients with...
