Introduction Diffusion imaging is typically performed in axial planes. This is largely due to its reliance on single-shot echo-planar imaging (EPI) which suffers from increased image distortion in sagittal and coronal planes because of concomitant gradient fields [1-2], especially with strong gradients and/or at relatively low B0-fields (including 1.5T). Diffusion-weighted (DW) imaging in non-a...

We present a new method to analyze, classify and characterize 3D landmark-based shapes. It is based on a framework provided by oriented matroid theory, that is on a combinatorial encoding of convexity properties. We apply this method to a set of skull shapes presenting various types of coronal craniosynostosis.

We investigate the effect of hydrostatic scale heights lambda(T) in coronal loops on the determination of the vertical temperature structure T&parl0;h&parr0; of the solar corona. Every method that determines an average temperature at a particular line of sight from optically thin emission (e.g., in EUV or soft X-ray wavelengths) of a mutlitemperature plasma is subject to the emission measure-we...

3 convexities were visualized: the aortic knob, pulmonary artery, and convexity of the left atrium. In addition, 2 radiotransparent bands were seen, one between the aortic knob and the pulmonary artery, and another between the cardiac base and the left hemidiaphragm. On magnetic resonance imaging, T2-weighted gradientecho (*) axial (Figure 2), and coronal (Figure 3) views Congenital Absence of ...

PURPOSE To describe abnormal white matter in the brain on MR in Wilson disease and to compare with anatomic location of white matter tracts. METHODS Forty-six patients with Wilson disease were examined. Axial T1-weighted inversion-recovery, axial T2-weighted spin-echo, and coronal T2*-weighted gradient-echo MR images were performed. Imaging studies were compared with clinical data. RESULTS ...

MR imaging was performed on a 2-year-old girl whose history included low Apgar score, hypotonicity, and myoclonic seizures at birth . Her psychomotor and growth development were retarded. She had mild microcephaly and was hypotonic. Electroencephalography showed generalized epileptogenic activity. MR imaging was performed on a 0.5-T scanner. T1-weighted images, SE 500/30, performed in the axial...

A 61-year-old gentleman presented with palpitations. MRI demonstrated a large left atrial tumour infiltrating left pulmonary veins. These findings were confirmed during surgery. Histology was reported as pulmonary squamous cell carcinoma (Figs. 1 and 2). Fig. 1. Axial (a) and coronal (b) T1-weighted fast spin echo MR images show a mass extending into the left atrium via the left pulmonary vein....

T2-weighted coronal images of hind limb region with a subcutaneous tumor (yellow circle); pre(A, E) and 3 h post-contrast injection (B, F). Fluorescence images (C, G) and Perl’s staining (D, H) of tumor tissue. Injected contrast agent: control NE (A-D) or RGD-NE (E-H). Figure 1. Negative staining TEM (A) and schematic representation (B) of RGD-NE. RGD-Functionalized Superparamagnetic Nanoemulsi...

The present post-mortem study of a brain from an Alzheimer patient showed on a T(2)∗-weighted gradient-echo 7.0-T MRI of a coronal brain section a hyposignal in the hippocampus, suggesting a microbleed. On the corresponding histological examination, only iron deposits around the granular cellular layer and in blood vessel walls of the hippocampus were observed without evidence of a bleeding. Th...
