Differentiation of acute and chronic myocardial infarction using T2-weighted imaging, late enhancement and T1 and T2 mapping - a pilot study at 3T
نویسندگان
چکیده
Background Qualitative assessment of myocardial T2-weighted and late enhancement (LGE) images has been demonstrated to differentiate acute from chronic myocardial infarction (AMI, CMI). Parametric mapping could help to overcome challenges in image quality and could contribute to making contrast media application obsolete. The aim of this pilot study was to analyze, whether T2and T1maps are useful to discriminate AMI from CMI.

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. Image...

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...

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. METHODS AND RESULTS Sixty ST-segment-elevation ...

PURPOSE We aimed to use a noninvasive method for quantifying T1 values of chronic myocardial infarction scar by cardiac magnetic resonance imaging (MRI), and determine its diagnostic performance. MATERIALS AND METHODS We performed cardiac MRI on 29 consecutive patients with known coronary artery disease (CAD) on 3.0 Tesla MRI scanner. An unenhanced T1 mapping technique was used to calculate T...
