Delay alternating with nutation for tailored excitation (DANTE) pulse trains are well appreciated as frequency-selective excitation methods in Fourier transform NMR and for spatial tagging in MRI. In this study, nonselective DANTE pulse trains are …

DANTE-SPACE is a promising black-blood technique that significantly improves arterial and venous blood suppression pre- and post-CE compared with conventional SPACE technique. Simultaneous high-resolution 3D carotid and intracranial imaging using DANTE-SPACE is feasible and time-efficient, with the potential ability to identify different plaque ...

Delay alternating with nutation for tailored excitation (DANTE) pulse trains are well appreciated as frequency-selective excitation methods in Fourier transform NMR and for spatial tagging in MRI. In this study, nonselective DANTE pulse trains are used in combination with gradient pulses and short repetition times as motion-sensitive ...

DANTE-SPACE significantly improved arterial and venous blood suppression compared with SPACE. Simultaneous high-resolution carotid and intracranial vessel wall imaging to potentially identify plaque components was feasible with a scan time under 6 min. Magn Reson Med 75:2286-2294, 2016. © 2015 Wiley …

2022年10月20日 · DANTE suppresses signals from both the blood and CSF using an alternative arrangement of low flip angle nonselective radiofrequency pulses with gradient pulses, causing static spin systems to fall into steady states. 2,12,16 Signal suppression of the blood and CSF results from the failure of flowing spins to establish this steady state due to ...

2025年2月7日 · To develop and assess a sequence using DANTE dark-blood preparation combined with FLASH readout (DANTE-FLASH) for rapid isotropic-resolution 3D peripheral vessel wall imaging at 3T. Numerical simulations were first conducted to optimize imaging parameters for maximizing the wall-lumen contrast.

2022年5月26日 · CONCLUSIONS: Accelerated postcontrast T1-DANTE-CAIPI-SPACE had fewer image artifacts, less motion, improved blood suppression, and a shorter scan time, but lower qualitative and quantitative SNR ratings relative to conventional T1-SPACE intracranial vessel wall MR imaging.

In addition to providing robust arterial blood suppression, DANTE significantly improves venous blood suppression. 22 Our study showed similar improvements in arterial and venous blood suppression with DANTE implementation in a larger cohort …

Materials and methods: Consecutive patients undergoing MR imaging had conventional postcontrast 3D T1-sampling perfection with application-optimized contrasts by using different flip angle evolution (SPACE) and either postcontrast delay alternating with nutation for tailored excitation (DANTE) flow-suppressed or DANTE-controlled aliasing in ...

2015年7月8日 · DANTE-SPACE is a promising BB technique that significantly improves arterial and venous blood suppression pre-CE and post-CE compared with the conventional SPACE technique. Simultaneous high-resolution 3D carotid and intracranial imaging using DANTE-SPACE is feasible and time-efficient, with the potential ability to identify different plaque ...
