“…Moreover, the reduced number of necessary breath-holds and the reduced overall data acquisition length may improve patient comfort. Because of these benefits, different approaches like real-time imaging [12], echoplanar imaging [13,14] or three-dimensional cine imaging [15] have been evaluated to reduce data acquisition lengths in cine CMR. Nevertheless, these approaches have not made their way into clinical routine because of their low temporal and spatial resolution or because of image artefacts inherent to these techniques.…”

“…Anatomic cardiac T1-and T2-weighted imaging is performed by means of ECG-gated multisection fast spin-echo (SE) or SE echo-planar imaging techniques (although the latter offer inferior signal-to-noise ratios and have been superseded by fast SE methods) (7,8). As these are fast imaging techniques with multiple SE readouts per repetition, they offer condensed imaging times with reduction in both respiratory and cardiac motion artifact when compared to conventional SE sequences; conversely, they have reduced signal-to-noise ratios and tissue contrast (due to the relatively short repetition and overall acquisition times).…”

Magnetic resonance (MR) imaging is an important tool in the evaluation of cardiac neoplasms. T1-weighted, T2-weighted, and gadolinium-enhanced sequences are used for anatomic definition and tissue characterization, whereas cine gradient-echo imaging is used to assess functional effects. Recent improvements in pulse sequences for cardiac MR imaging have led to superior image quality, with reduced motion artifact and improved signal-to-noise ratio and tissue contrast. Although there is some overlap in the MR imaging appearances of cardiac tumors, particularly of primary malignancies, differences in characteristic locations and features should allow confident differentiation between benign and malignant tumors. Indicators of malignancy at MR imaging are invasive behavior, involvement of the right side of the heart or the pericardium, tissue inhomogeneity, diameter greater than 5 cm, and enhancement after administration of gadolinium contrast material (as a result of higher tissue vascularity). Concomitant pericardial or pleural effusions are rare in benign processes but occur in about 50% of cases of malignant tumors. MR imaging offers improved resolution, a larger field of view, and superior soft-tissue contrast compared with those of echocardiography, suggesting that knowledge of the MR imaging features of cardiac neoplasms is important for accurate diagnosis and management.

“…LV volumes are calculated using the multi-slice disk summation method Heart Fail Rev (2011) 16:327-337 333 with a single breath-hold could significantly reduce data acquisition time and improve clinical workflow. Threedimensional cine, echo-planar, and real-time imaging have reduced the duration of acquisition time, but at the expense of spatial and temporal resolution and increased artifacts [92][93][94]. Another highly accelerated cine imaging approach for determining LVEF relies on combining short and long axes imaging with guide-point modeling with subsequent post-processing assessment of LV function [84,95].…”

Novel techniques for assessment of left ventricular systolic function

The evaluation of left ventricular systolic function is one of the most common reasons for referral for a non-invasive cardiac imaging study. In addition to its diagnostic and prognostic value, an assessment of ejection fraction can also be used to guide medical and device therapy. Thus, obtaining an accurate and reproducible assessment of LVEF is essential for patient management. This review will focus on novel multi-modality techniques used for the quantification of left ventricular systolic function. Emerging echocardiography techniques such as three-dimensional echocardiography and strain imaging and their incremental role over traditional 2D imaging will be discussed. In addition, new developments expanding nuclear imaging techniques' evaluation of left ventricular systolic function will be reviewed. Finally, an overview of advances in imaging techniques such as cardiac magnetic resonance and cardiac computed tomography, which now allow for an accurate and highly reproducible assessment of LVEF, will be presented.

Normal heart: evaluation with echo-planar MR imaging.

Abstract: Diagnostic images of the heart were obtained with both SE EPI and GRE EPI. GRE EPI is more suitable for flow studies because of the higher and more homogeneous intravascular SI.
