Radial cardiac T2 mapping with alternating T2 preparation intrinsically introduces motion correction

Background T2 mapping through variation of the T2 preparation (T2Prep) duration has been increasingly used to robustly detect and quantify cardiac edema (Giri et al., JCardiovMagnReson2009). However, if images with incremental T2Prep duration are acquired in a sequential fashion, irregular breathing patterns and heart rates may adversely affect the quality of the T2 maps due to misalignment of ...

Free-breathing multi-slice myocardial T2 mapping using slice-selective T2 magnetization preparation

Background Quantitative myocardial T2 mapping allows non-invasive assessment of myocardial inflammation/edema [1]. Current implementations commonly use a T2-prepared (T2prep) SSFP sequence to acquire different T2 weighted images at different echo times to generate the T2 maps [2,3]. However, all current techniques are designed for single slice acquisition with long rest cycles (3-6 sec) after e...

Joint myocardial T1 and T2 mapping using a combination of saturation recovery and T2 -preparation.

PURPOSE To develop a heart-rate independent breath-held joint T1 -T2 mapping sequence for accurate simultaneous estimation of coregistered myocardial T1 and T2 maps. METHODS A novel preparation scheme combining both a saturation pulse and T2 -preparation in a single R-R interval is introduced. The time between these two pulses, as well as the duration of the T2 -preparation is varied in each ...

Breath-held high-resolution cardiac T2 mapping with SKRATCH

Background Several cardiac T2 mapping techniques with varying T2 preparation (T2Prep) times have been proposed for the quantification of cardiac edema [1-3]. Among these, radial T2 mapping, which is robust to motion artifacts, suffers from a low signal-to-noise ratio (SNR) caused by the undersampling of the k-space periphery and by its density compensation function (DCF) (Fig. 1a). However, sin...

T2-mapping and T2*-mapping for detection of intramyocardial haemorrhage: a head-to-head comparison with T2-weighted imaging

Methods Twenty patients underwent CMR at 3T (Achieva TX system, Philips Healthcare, Best, The Netherlands) within 3 days following reperfused ST-elevation MI. Black blood, cine, T2w, T2-mapping, T2*-mapping and LGE imaging (0.1mmol/kg gadolinium DTPA) were performed in identical short axis locations using the ‘3 of 5’ approach. Data were evaluated offline using commercial software (cvi42 v4.1.5...
