An abscess and a THAD (white arrow) on a contrast CT in native, arterial, portal and delayed phase. [1] [predatory publisher]Transient hepatic attenuation differences (THAD) are areas of enhancement during the arterial phase of contrast CT of the liver.
In physics, attenuation (in some contexts, extinction) is the gradual loss of flux intensity through a medium.For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at variable attenuation rates.
Evidence from subcortical small infarcts suggests that motor fibers are somatotopically arranged in the human corona radiata. Following subtotal brain damage, localization of the corticofugal projection in the corona radiata and internal capsule can assist in evaluating a patient's residual motor capacity and predicting their potential for functional restitution.
Fogging phenomenon in computerized tomography (CT) scanning of the head is vanishing signs of an infarct on the serial CT imaging in a patient with a recent stroke. [1] It is a reversal of the hypodensity on the CT after an acute ischemic stroke.
In neuroanatomy, the centrum semiovale, semioval center or centrum ovale [1] is the central area of white matter found underneath the cerebral cortex. [2] The white matter, located in each hemisphere between the cerebral cortex and nuclei, as a whole has a semioval shape.
Focal fatty liver (FFL) is localised or patchy process of lipid accumulation in the liver. [1] It is likely to have different pathogenesis than non-alcoholic steatohepatitis which is a diffuse process.
MRI scans showing hyperintensities. A hyperintensity or T2 hyperintensity is an area of high intensity on types of magnetic resonance imaging (MRI) scans of the brain of a human or of another mammal that reflect lesions produced largely by demyelination and axonal loss.
Intracranial hemorrhage is a serious medical emergency because the buildup of blood within the skull can lead to increases in intracranial pressure, which can crush delicate brain tissue or limit its blood supply.
