Free-breathing real-time cardiac cine MR for evaluation of left-ventricular function: Comparison to standard multi-breath-hold cardiac cine MR in 50 patients
نویسندگان
چکیده
Background Electrocardiogram (ECG)-gated breath-hold cardiac cine magnetic resonance imaging (MRI) is generally accepted as the gold standard for left-ventricular (LV) volume assessment. However, it may fail in patients with arrhythmia, impaired breath-hold capacity, and poor ECG gating. Recently, sparse real-time (RT) cine using a prototype sequence with sparse sampling and iterative reconstruction has been proposed to accelerate cine MRI (Kido et al. SCMR; 2015). The purpose of this study was to evaluate the diagnostic quality and accuracy of sparse free-breathing (FB) RT cine MRI for the quantification of LV function compared with standard multi-breath-hold cine MRI.

Single breath-hold real-time MR cardiac cine for evaluation of left ventricular function
Background Magnetic Resonance (MR) cardiac cine is generally accepted as the gold standard for left ventricular (LV) volume assessment. Recently, Real-Time (RT) cine with sparse sampling technique and iterative reconstruction has been applied to accelerate cine MR. However, in prospective electrocardiogram (ECG) triggered RT cine MR, it may be difficult to capture the true end diastole phase be...
متن کاملSTRUCTURE AND FUNCTION Rapid Evaluation of Right and Left Ventricular Function and Mass Using Real-Time True-FISP Cine MR Imaging Without Breath-Hold: Comparison with Segmented True-FISP Cine MR Imaging with Breath-Hold
Purpose. To evaluate the accuracy of cardiac function measured with real-time true fast imaging with steady-state precession (True-FISP) cine without breath-hold compared with those measured from segmented True-FISP cine with breath-hold. Methods. Eighteen consecutive patients and six healthy volunteers were enrolled in the study group. Both realtime multislice True-FISP cine imaging without br...
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 کاملHighly accelerated real-time cardiac cine MRI using k-t SPARSE-SENSE.
For patients with impaired breath-hold capacity and/or arrhythmias, real-time cine MRI may be more clinically useful than breath-hold cine MRI. However, commercially available real-time cine MRI methods using parallel imaging typically yield relatively poor spatio-temporal resolution due to their low image acquisition speed. We sought to achieve relatively high spatial resolution (∼2.5 × 2.5 mm...
متن کاملCompressed sensing real-time cine cardiovascular magnetic resonance: accurate assessment of left ventricular function in a single-breath-hold
BACKGROUND Cardiovascular cine magnetic resonance (CMR) accelerated by compressed sensing (CS) is used to assess left ventricular (LV) function. However, it is difficult for prospective CS cine CMR to capture the complete end-diastolic phase, which can lead to underestimation of the end-diastolic volume (EDV), stroke volume (SV), and ejection fraction (EF), compared to retrospective standard ci...
