Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
Myelography is a type of radiographic examination that uses a contrast medium (e.g. iodised oil [1]) to detect pathology of the spinal cord, including the location of a spinal cord injury, cysts, and tumors. Historically the procedure involved the injection of a radiocontrast agent into the cervical or lumbar spine, followed by several X-ray ...
Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF). It is useful in several applications, such as for spinal anesthesia, chemotherapy, or pain management. This route is also used to introduce drugs that fight ...
Through-plane analysis is usually done perpendicular to the aqueduct and is more accurate for quantitative evaluation because this minimizes the partial volume effect, a main limitation of PC-MRI. The partial volume effect occurs when a voxel includes a boundary of static and moving materials, this leads to an overestimate of phase which ...
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
This may be done by placing a solid source of radiation adjacent to the tumor in the form of a seed, ribbon or capsule (brachytherapy) [1] or by giving the patient a liquid source of radiation that travels through the body and kills cancer cells (system therapy). In this case the radiation is usually given in the form of injections, ingesting a ...
A new study released Wednesday in the Journal of the American Medical Association revealed that 50 minutes of continuous cell phone use causes temporary changes in the brain. That period of cell ...
Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...
