Assessment of blood flow patterns in the pulmonary artery using 4D flow
نویسندگان
چکیده
Methods Eighteen volunteers and two patients underwent 4D Flow scan on a Phillips system (25 frames, 2.5mm). Flow was visualized by streamlines and particle traces ("GTFlow” software). 2D planes placed in 5 locations were used to grade flow patterns: 1) just after to the pulmonary valve, 2) before the PA bifurcation, 3) between plane 1 and 2, 4) Right-PA, and 5) Left-PA. Sagital and coronal planes were also analyzed. VOs that lasted at least 2 frames were registered (start, finish and peak-frame; direction, size, and distance between vortexcenter and vessel-center).

Atlas-based analysis of 4D flow CMR: Automated vessel segmentation and flow quantification
BACKGROUND Flow volume quantification in the great thoracic vessels is used in the assessment of several cardiovascular diseases. Clinically, it is often based on semi-automatic segmentation of a vessel throughout the cardiac cycle in 2D cine phase-contrast Cardiovascular Magnetic Resonance (CMR) images. Three-dimensional (3D), time-resolved phase-contrast CMR with three-directional velocity en...

In this investigation, a mathematical model for studying oscillatory flow of blood in a stenosed artery under the influence of transverse magnetic field through porous medium has been developed. The equations of motion of blood flow are solved analytically. The analytical expressions for axial velocity, volumetric flow rate, pressure gradient, resistance to blood flow and shear stress have been...

Accurate assessment of gestational age, fetal growth, and the detection of fetal and placental abnormalities are major benefits of sonography. Color Doppler can be used to assist in the identification of vascular architecture, detection of vascular pathology and visualization of blood flow changes associated with physiologic processes and disease states. The clinical applications of obstetrical...

BACKGROUND To assess changes in right heart flow and pulmonary artery hemodynamics in patients with repaired Tetralogy of Fallot (rTOF) we used whole heart, four dimensional (4D) velocity mapping (VM) cardiovascular magnetic resonance (CMR). METHODS CMR studies were performed in 11 subjects with rTOF (5M/6F; 20.1 ± 12.4 years) and 10 normal volunteers (6M/4F; 34.2 ± 13.4 years) on clinical 1....

PURPOSE To compare pulmonary artery flow using Cartesian and radially sampled four-dimensional flow-sensitive (4D flow) MRI at two institutions. METHODS Nineteen healthy subjects and 17 pulmonary arterial hypertension (PAH) subjects underwent a Cartesian 4D flow acquisition (institution 1) or a three-dimensional radial acquisition (institution 2). The diameter, peak systolic velocity (Vmax), ...
