Extramedullary haematopoiesis is the production of blood elements outside the bone marrow cavity. In our case computed tomography and magnetic resonance imaging revealed the presence of a rare localization of extramedullary haematopoiesis with encasement of the biliary system in a 59 years-old male Caucasian patient, with chronic myelofibrosis and hepatic failure's symptomatology. Computed tomo...

A 58-year-old man presented himself to the emergency room with chief complaints of chest pain and progressively exacerbated dyspnea for 4 days. Electrocardiography showed Q wave and ST-segment elevation in inferior leads. A thallium scan showed mixed ischemia and infarction in the inferior wall of the left ventricle. However, coronary artery angiography showed normal coronary arteries. Cardiac ...

We have experimentally studied micrometer-scale domain wall (DW) motion driven by a magnetic field and an electric current in a Co/Pt multilayer strip with perpendicular magnetic anisotropy. The thermal activation energy for DW motion, along with its scaling with the driving field and current, has been extracted directly from the temperature dependence of the DW velocity. The injection of DC cu...

In our study, in a 52-year-old man, specific and nonspecific findings of Schistosoma infestation were examined using ultrasonography, computed tomography, and magnetic resonance imaging. On computed tomography, capsular and septal calcifications and contrast enhancement of the liver capsule were seen. On T1-weighted magnetic resonance images diffuse hypointensity was seen in periportal spaces; ...

A 7-year-old girl with tonsillar infection with antibiotics. Two weeks later, there was a right sided neck lump. Computed tomography scans demonstrated a predominantly hypodense right retropharyngeal area with peripheral enhancement and mass effect. There was intense enhancement within the postero-superior aspect of the lesion which was continuous with the right internal carotid artery. Ultraso...

In this work we theoretically reveal the huge local field enhancement in a so-called perfect plasmonic absorber. We study the power absorption of light in a planar grid modelled as an effective sheet with zero optical thickness. The key prerequisite of the total absorption is the simultaneous presence of both resonant electric and magnetic modes in the structure. We show that the needed level o...

We describe the magnetic resonance imaging (MRI) findings of 13 cm-sized low-grade angiosarcoma of the breast that occurred in a 23-year-old woman. Magnetic resonance examination revealed an ill-defined mass with marked high-signal intensity on T2-weighted images and persistent heterogeneous enhancement. Thirty months later she developed bone metastases, incidentally found on an MRI performed t...

Hyperpolarized He gas, where the nuclear spin polarization has been increased to several tens of percent by optical pumping, can couple such a large negative resistance into an external circuit that masing can ensue. The masing threshold can be suppressed by application of a magnetic field gradient. However, edge enhancement, that is, the less effective diffusional damping of the precessing mag...

The magnetic-field-dependent ordering temperature of the quasi-2D quantum Heisenberg antiferromagnet (QHAF) Cu(pz)2(ClO4)2 was determined by calorimetric measurement in applied dc fields up to 33 tesla. The magnetic phase diagram shows a round maximum at 5.95 K and 17.5 T (at ≈ 1/3 of its saturation field), a 40 percent enhancement of the ordering temperature above the zero field value of 4.25 ...
