Ultrafast in-line interactive m-mode tool for quantification of left-ventricular (LV) septo-lateral wall motion (SLWM) from high-temporal resolution (6-12ms) cardiac cine steady-state free precession (SSFP) images

چکیده
Introduction While conventional temporal resolution on the order of 30-50 ms is sufficient for calculating LV functional metrics such as global ejection fraction (EF), it is insufficient to accurately capture subtle regional wall motion dyssynchrony. A higher frame-rate cine imaging, e.g., 100 fps imposes an undue burden on the manual segmentation, precluding more sophisticated analyses, e.g., measurement of SLWM delays. A robust algorithm that inscribes papillary and trabeculae as LV cavity is a necessary pre-requisite for such an analysis.

Ultrafast computation of left ventricular ejection fraction using temporal intensity variation in cine steady-state free precession cardiac MR images with or without contrast
Background Adaptation of CMR in clinical setting among non-experts is limited due to the time-consuming and labor-intensive nature of both CMR data acquisition and post-processing. In many clinical instances, e.g., myocardial viability (MV), it is time efficient to acquire LV cine SSFP images after contrast administration. In this study we clinically validate an ultrafast algorithm that compute...
متن کاملDifferences in left ventricular strain measurements between cine DENSE cardiac magnetic resonance and SSFP feature tracking
Background Left ventricular (LV) mechanics (e.g., strain) provide a clinically relevant description of LV function. Automated endocardial feature tracking (FT) for steady state free precession (SSFP) images is increasingly used to quantify strain, yet accuracy limitations have been noted. Furthermore, similarities between FT and global strain calculated from endocardial contour lengths have bee...
متن کاملComparison of breath hold and free breathing respiratory triggered retrospectively cardiac gated cine steady-state free precession (RT-SSFP) imaging in adults
Background The cine steady-state free-precession (SSFP) is the standard sequence for left ventricular (LV) function evaluation. However, SSFP mandates uninterrupted RF excitations to maintain steady-state (SS) during suspended respiration. In patients who cannot perform breath-holds (BH), a respiratory triggered (RT) free breathing (FB) retrospectively cardiac gated cine SSFP sequence that driv...
متن کاملCardiovascular magnetic resonance myocardial feature tracking detects quantitative wall motion during dobutamine stress
BACKGROUND Dobutamine stress cardiovascular magnetic resonance (DS-CMR) is an established tool to assess hibernating myocardium and ischemia. Analysis is typically based on visual assessment with considerable operator dependency. CMR myocardial feature tracking (CMR-FT) is a recently introduced technique for tissue voxel motion tracking on standard steady-state free precession (SSFP) images to ...
متن کاملCardiovascular magnetic resonance evaluation of left ventricular peak filling rate using steady-state free precession and phase contrast sequences
BACKGROUND We investigated a practical method to measure peak filling rate (PFR) as an indicator of diastolic function of the left ventricle. Ten adult volunteers underwent cine MR imaging using steady-state free precession (SSFP) and phase contrast (PC) sequences to measure PFR. Two PC image sets were acquired at the mitral valve orifice, and PFR was determined from the set with high true temp...
