Frequency drift during intensive SSFP scanning: implications and solution for 3T neonatal CMR
نویسندگان
چکیده
Background Balanced-SSFP is widely used because of its inherent highcontrast and high-SNR efficiency, and therefore is an obvious choice for neonatal cardiac applications. Typically, multiple averages are needed due to the high-spatial and temporal resolutions required, especially for the smallest preterm infants. Therefore, prolonged intensive scans are required placing high demands on scanner hardware. Consequently, one of the two critical prerequisites for successful SSFP sufficient B0 shimming and stable scanner frequency is often not met using standard protocols.

Robust and fast SSFP for the evaluation of LV function at 3T
Background 3T MRI is advantageous to CMR as it offers higher SNR and better T1 contrast. Its slow clinical adoption is partly due to the lack of robustness in SSFP cine imaging [1]. Banding artifact in SSFP caused by main field inhomogeneity is common at 3T. Wideband SSFP [2] or prescans (shimming, frequency scout, etc.) are needed to avoid/ reduce the artifact, increasing patient scan time. We...
متن کاملRapid phase-modulated water excitation steady-state free precession for fat suppressed cine cardiovascular MR
BACKGROUND The purpose of this article is to describe a steady-state free precession (SSFP) sequence for fat suppressed cine cardiovascular magnetic resonance (CMR). A rapid phase-modulated binomial water excitation (WE) pulse is utilized to minimize repetition time and acquisition time. METHODS Three different water-excitation pulses were combined with cine-SSFP for evaluation. The frequency...

Methods A total of 20 consecutive patients scheduled to undergo a clinically indicated CMR in normal sinus rhythm and able to perform apnea were prospectively enrolled to be scanned in a 3T system (MAGNETOM Verio, Siemens, Germany). Frequency scout images were acquired in two and four chamber views and the frequency offset associated with least banding artifacts involving the heart was manually...
متن کاملThe intra-observer reproducibility of cardiovascular magnetic resonance myocardial feature tracking strain assessment is independent of field strength
BACKGROUND Cardiovascular magnetic resonance myocardial feature tracking (CMR-FT) is a promising novel method for quantification of myocardial wall mechanics from standard steady-state free precession (SSFP) images. We sought to determine whether magnetic field strength affects the intra-observer reproducibility of CMR-FT strain analysis. METHODS We studied 2 groups, each consisting of 10 hea...
متن کاملThe extent of myocardium at risk for LAD, RCA and LCx using contrast enhanced SSFP and T2-weighted imaging
Background Contrast enhanced SSFP (CE-SSFP) and T2-weighted triple inversion recovery imaging (T2w) have both been clinically validated for determining myocardium at risk (MaR) by cardiovascular magnetic resonance (CMR), using myocardial perfusion SPECT (MPS) as reference standard. Previously, MPS has been used to describe the coronary perfusion territories during myocardial ischemia. Compared ...
