Versatile and Highly Efficient MRI Simulation of Arbitrary Motion in KomaMRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To extend the KomaMRI simulator with motion capabilities that enable the simulation of both simple, parametrizable motion patterns and arbitrarily complex spin trajectories. Additionally, we introduce a novel file format for storing and sharing dynamic digital phantoms.

Coronary Artery Blood Flow Imaging Using 3D Flow MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose In this work, a 3D phase contrast (PC) technique is presented, which enables flow velocity measurements in three spatial directions, simultaneously covering the proximal left (LCA) and right (RCA) coronary arteries and yielding both morphological and flow information.

Age‐Dependent Correlation of Pulmonary Function Impairment and Aortic Arch Stiffness in Mice

Pediatric Discovery, EarlyView.
This study examined the relationship between aortic arch stiffness and lung function in aging mice. Multiple linear regression modeling showed moderate to strong correlations between the rise in aortic arch stiffness and changes in lung function as the mice progressively aged.

Consideration on Estimating Mean Pulmonary Artery Pressure Using Early Diastolic Pulmonary Regurgitation Velocity

Sonography, EarlyView.
ABSTRACT Estimation of mean pulmonary artery pressure (mPAP) using peak velocity of pulmonary regurgitation (PR) obtained via continuous‐wave Doppler echocardiography has been applied in clinical practice. However, the theoretical basis for this method and whether to include right atrial pressure (RAP) in the calculation vary across reports, with no ...

Normal ultrasound measurements of atria and heart ventricles of 25–64 years old people

Сеченовский вестник, 2013
This article presents the results of research of the ultrasound dimensions of the atria and heart ventricles in 80 healthy subjects reached by using an ultrasonic machine SSD-630 (the company ≪Aloka≫, Japan).
