MRI is a noninvasive, ionizing radiation-free imaging modality that has become an indispensable medical diagnostic method. The literature suggests MRI as a potential diagnostic modality in dentomaxillofacial radiology. However, current MRI equipment is designed for medical imaging (eg, brain and body imaging), with general-purpose use in radiology.

- This study aimed to compare different methods of evaluating heart function using MR 4D flow imaging against echocardiography as a reference.
- Researchers tested 60 subjects and measured key heart velocities (E, A) using three evaluation strategies, noting their correlations with echocardiography results.
- The max-velocity method showed the most accurate outcomes, allowing for reliable assessment of heart function without significant bias, thus supporting the use of established echocardiographic thresholds for analysis.
Article Synopsis
- - The study aimed to compare left ventricular (LV) and left atrial (LA) function parameters measured using cardiac MR imaging techniques during both breath-holding and regular breathing to identify differences.
- - A total of 56 participants (average age 58) without heart failure underwent imaging, and various LV and LA volumetric and velocity functions were analyzed using statistical methods to assess differences between breath-holding and breathing conditions.
- - Significant differences were found, indicating that LV and LA performance metrics varied notably between breath-holding and breathing, suggesting that imaging techniques might yield inconsistent results based on the breathing method used during the procedure.
Background: Myocardial strain assessed with cardiovascular magnetic resonance (CMR) feature tracking can detect early left ventricular (LV) myocardial deformation quantitatively in patients with a variety of cardiovascular diseases, but this method has not yet been applied to quantify myocardial strain in patients with atrial fibrillation (AF) and no coexistent cardiovascular disease, i.e., the early stage of AF.
