Magnetic Resonance ImagingMagnetic Resonance SpectroscopyProton magnetic resonance spectroscopy (MRS) allows accurate and noninvasive biochemical assay of living tissues. In vivo measurements provided by MRS have greatly enhanced our understanding of the pathophysiology of dementia. Increases in choline and ...
The magnetic resonance testing method reacts on a test region with at least one sequence, and includes at least one HF excitation pulse (RF4) for exciting the core magnetising in at least one part of the test region. In the time interval (t/o - t/1 or t/o - t/2), also before...
Magnetic resonance imaging (MRI), three-dimensional diagnostic imaging technique used to visualize organs and structures inside the body without the need for X-rays or other radiation. MRI is valuable for providing detailed anatomical images and can reve
Aim To study the associations between magnetic resonance proton spectroscopy (MRS) data and apparent diffusion coefficients (ADC) from the preterm brain with developmental outcome at 18 months corrected age and clinical variables. Materials and methods A prospective observational cohort study of 67 infant...
Combined helium‐3/proton magnetic resonance imaging measurement of ventilated lung volumes in smokers compared to never‐smokers Purpose To use a combination of helium-3 (3-He) magnetic resonance imaging (MRI) and proton single-shot fast spin echo (SSFSE) to compare ventilated lung v... N ...
Because of its complexity, the spine is probably the most difficult part of the skeletal system to evaluate radiologically. Improvement of computed tomography (CT) scanners and the advent of magnetic resonance imaging (MRI) have changed the approach to diagnostic imaging of the spine. Previously, ...
A black blood magnetic resonance angiogram is produced by exciting dipoles and repeatedly inverting the resonance to produce a series of magnetic resonance echoes. Early echoes are more heavily proton density weighted than later echoes, which are more heavily T2 weighted. The magnetic resonance echoes...
Magnetic resonance imaging is a widespread clinical tool for the detection of soft tissue morphology and pathology. However, the clinical deployment of magnetic resonance imaging scanners is ultimately limited by size, cost, and space constraints. Here, we discuss the design and performance of a low...
Magnetic resonance imaging is a noninvasive, volume rendering diagnostic technique that uses lanthanide complexes to enhance proton relaxation. Magnetic resonance imaging is not limited by light scattering as optical microscopic techniques are, and allows imaging of whole animals. Clinical contrast agents ...
We aimed to evaluate the feasibility of quantification of liver, pancreas, spleen, vertebral bone marrow, and renal cortex R2* and magnetic resonance imaging-proton density fat fraction (MRI-PDFF) and to evaluate the correlations among them in patients with transfusion-related iron overload.A tot...
