“…Cine-SSFP acquisitions use a balanced gradient waveform, which maintains both transverse and longitudinal magnetization. This leads to both: 1) T1-weighting, which allows DCE areas to be detected and 2) T2-weighting, which enhances signal from edematous areas (24). The postcontrast cine-SSFP sequence thereby provides information on both regional function and myocardial involvement, in close correlation with the "conventional" assessment of myocardial damage obtained with the IR-GRE sequence (25).…”

Purpose:To prospectively assess the use of cardiac MRI with delayed contrast enhancement (DCE) for identifying patients with active myocarditis among those presenting with acute coronary syndrome (ACS) but no coronary stenosis. Materials and Methods:A total of 27 consecutive patients (age ϭ 45 Ϯ 17 years; 14 male) presenting with ACS (chest pain, positive troponin-I) and no coronary stenosis, underwent cardiac MRI 9 Ϯ 7 days after pain onset and 8 Ϯ 5 months later (N ϭ 19). Steady-state free-precession pulse (SSFP) sequence was applied for the assessment of myocardial function and both inversion-recovery (IR) and SSFP sequences were used for analyzing the topography and extent of DCE areas. Rest sestamibi-gated-single photon emission CT (SPECT) was also systematically performed.Results: Subepicardial DCE pattern typical of acute myocarditis was documented in 12 patients (44%). Ischemic DCE pattern (transmural or subendocardial focal DCE) was documented in 12 of the 15 remaining patients (44%). Patients with subepicardial DCE had: higher C-reactive protein (CRP) levels (38 Ϯ 32 vs. 14 Ϯ 24 mg/mL; P ϭ 0.04), lower Framingham cardiovascular risk (3 Ϯ 3% vs. 9 Ϯ 5%; P Ͻ 0.001), lower incidence of perfusion SPECT defects (17% vs. 73%; P ϭ 0.01), higher left ventricular (LV) enddiastolic volume (77 Ϯ 16 vs. 64 Ϯ 10 mL/m 2 ; P ϭ 0.02), and higher regression of DCE areas at follow-up (-65 Ϯ 17% vs. -18 Ϯ 23%; P ϭ 0.002).Conclusion: DCE pattern of active myocarditis can be seen in patients presenting with ACS but no coronary stenosis.

“…The high CNR of cine-SSFP techniques allows a more accurate contour detection of the epicardial and endocardial borders, which makes it a robust technique [16,17]. Cine SSFP is hence the most widely used method to assess cardiac function, which is a paramount parameter in the diagnosis, assessment of severity, and follow-up of cardiac diseases [17,18]. Currently, this sequence is performed before any contrast medium injection to allow the maximum contrast between myocardium and left ventricular (LV) chamber [16], but the drawback is the lengthened overall acquisition time, due to the delay between first-pass and delayedenhancement sequences.…”

The accuracy of contrast-enhanced cine magnetic resonance (cine-MR) imaging to determine left ventricular function was assessed by comparison with the established noncontrast cine-MR sequences. Contrast-enhanced balanced steady-state free precession (cine-SSFP) sequences were compared with precontrast cine-SSFP sequences in the assessment of left ventricular contractile function in 30 consecutive patients with various cardiac diseases. Five to eight short-axis image sections were obtained in each patient. Quantitative data were analyzed using a paired t-test and linear regression analysis. Qualitative assessment of images was made following a 16-segment analysis. There was no significant difference between the two sequences in regional wall motion, end-diastolic volumes (EDV) and end-systolic volumes (ESV), stroke volume, left ventricular mass, as well as left ventricular ejection fraction (LVEF), despite slight delayed subendocardial enhancement in ten patients with myocardial infarction. All the values studied above were closely correlated between both cine-SSFP sequences (Spearman r=0.85-0.97, P<0.0001 for all comparisons). Contrast-enhanced cine-SSFP sequences can be used as a similar diagnostic tool as precontrast cine-MR sequences in the assessment of left ventricular contractile function.
