Background: Unidentified heart failure occurs in patients with multiple myeloma when their heart was involved. CMR with late gadolinium enhancement (LGE) and T1 mapping can identify myocardial amyloid infiltrations.
Purpose: To explore the role of CMR with late gadolinium enhancement (LGE) and T1 mapping for detection of multiple myeloma patients'heart.
Material And Methods: A total of 16 MM patients with above underwent CMR (3.0-T) with T1 mapping (pre-contrast and post-contrast) and LGE imaging. In addition, 26 patients with non-obstructive hypertrophic cardiomyopathy and 26 healthy volunteers were compared to age- and sex-matched healthy controls without a history of cardiac disease, diabetes mellitus, or normal in CMR. All statistical analyses were performed using the statistical software GraphPad Prism. The measurement data were represented by median (X) and single sample T test was adopted. Enumeration data were represented by examples and Chi-tested was adopted. All tests were two-sided, and P values < 0.05 were considered statistically significant.
Results: In MM group, LVEF was lower than healthy controls and higher than that of non-obstructive hypertrophic cardiomyopathy group, but without statistically significant difference (%: 49.1 ± 17.5 vs. 55.6 ± 10.3, 40.4 ± 15.6, all P > 0.05). Pre-contrast T1 values of MM group were obviously higher than those of healthy controls and non-obstructive hypertrophic cardiomyopathy group (ms:1462.0 ± 71.3vs. 1269.3 ± 42.3, 1324.0 ± 45.1, all P < 0.05). 16 cases (100%) in MM group all had LGE.
Conclusion: LGE joint T1 mapping wider clinical use techniques and follow-up the patients'disease severity.

Cardiac thrombus: can T1 and T2 mapping replace contrast enhanced images?

Ankara University Faculty of Medicine, Department of Radiology, Ankara, Turkey. Electronic address:
Aim: The aim of the study was to evaluate and compare contrast-to-noise ratios (CNRs) and signal-to-noise ratios (SNRs) of pre- and postcontrast T1 maps, T2 maps, early and late gadolinium images in terms of visual assessment of cardiac thrombus, to see if maps can replace contrast-enhanced images for detection of cardiac thrombus.
Materials And Methods: T1, T2 maps, and postcontrast images of 22 patients with cardiac thrombus were retrospectively evaluated for SNR and CNR. SNR and CNR values of thrombus, blood pool, and myocardium measured at maps and contrast-enhanced images were compared with each other.
Utilization of Cardiac Magnetic Resonance Imaging for Assessing Myocardial Fibrosis in Prognosis Evaluation and Risk Stratification of Patients with Dilated Cardiomyopathy.

Dilated cardiomyopathy (DCM) is the ultimate manifestation of the myocardial response to various genetic and environmental changes and is characterized mainly by impaired left ventricular systolic and diastolic function. DCM can ultimately lead to heart failure, ventricular arrhythmia (VA), and sudden cardiac death (SCD), making it a primary indication for heart transplantation. With advancements in modern medicine, several novel techniques for evaluating myocardial involvement and disease severity from diverse perspectives have been developed.

Cardiac magnetic resonance (CMR) allows for analysis of cardiac function and myocardial tissue characterization. Increased left ventricular mass (LVM) is an independent predictor of cardiovascular events; however, the diagnosis of left ventricular hypertrophy and its prognostic value strongly depend on the LVM indexation method. Evaluation of the quantity and distribution of late gadolinium enhancement assists in clinical decisions on diagnosis, cardiovascular assessment, and interventions, including the placement of cardiac implantable electronic devices and the choice of an optimal procedural approach.

Background: Hemodynamic force (HDF) from cardiac MRI can indicate subclinical myocardial dysfunction, and help identify early cardiac changes in patients with Fabry disease (FD). The hemodynamic change in FD patients remains unclear.
Purpose: To explore HDF changes in FD and the potential of HDF measurements as diagnostic markers indicating early cardiac changes in FD.

Background: Primary heart involvement (pHI) is frequent in systemic sclerosis (SSc), and is associated with a poor prognosis. Therapeutic strategies to treat SSc-pHI are not yet defined.
Objectives: To evaluate the efficacy of immunosuppressive therapy on cardiac magnetic resonance (CMR) features in patients with CMR-proven SSc-pHI.
