Which piece of computer equipment is about the size of a kidney

Contrast dye is injected into the spinal canal and a CT scan or a series of x-rays is taken. People may experience some pain during the spinal tap as well as headache following the spinal tap. There is a slight risk of fluid leakage or allergic reaction to the dye.

A polysomnogram measures brain and body activity during sleep. It is performed over one or more nights at a sleep center. The person may be videotaped to note any movement during sleep. Results are then used to identify any characteristic patterns of sleep disorders, including restless legs syndrome, periodic limb movement disorder, insomnia, and breathing disorders such as sleep apnea.

Polysomnograms are noninvasive, painless, and risk-free. Thermography also known as digital infrared thermal imaging uses infrared sensing devices to measure small temperature changes and thermal abnormalities between the two sides of the body or within a specific organ. Some scientists question its use in diagnosing neurological disorders.

It may be used to evaluate complex regional pain syndromes and certain peripheral nerve disorders, and nerve root compression. It is performed at a specialized imaging center, using infrared light recorders to take pictures of the body. The information is converted into a computer-generated two-dimensional picture of abnormally cold or hot areas indicated by color or shades of black and white.

Thermography does not use radiation and is safe, risk-free, and noninvasive. Ultrasound imaging , also called ultrasonography, uses high-frequency sound waves to obtain images inside the body.

During an ultrasound examination, the person lies on a table or reclines in an examination chair. A jelly-like lubricant is applied to the bare skin and a transducer, which both sends and receives high-frequency sound waves, is passed over the body. The sound wave echoes are recorded and displayed as a computer-generated real-time visual image of the structure or tissue being examined.

Ultrasound is painless, noninvasive, and risk-free. The test is performed on an outpatient basis and takes between 15 and 30 minutes to complete. Ultrasound can be used to assess changes in the anatomy of soft tissues, including muscle and nerve. It is more effective than an x-ray in displaying soft tissue changes, such as tears in ligaments or soft tissue masses.

In pregnant women, ultrasound can suggest the diagnosis of conditions such as chromosomal disorders in the fetus. The ultrasound creates a picture of the fetus and the placenta. Ultrasound also may be used in newborns to diagnose hydrocephalus build-up of cerebrospinal fluid in the brain or hemorrhage. X-rays can be used to view any part of the body, such as a joint or major organ system.

In a conventional x-ray, a concentrated burst of low-dose ionized radiation passes through the body and onto a photographic plate. Since calcium in bones absorbs x-rays more easily than soft tissue or muscle, the bony structure appears white on the film.

Any vertebral misalignment or fractures can be seen within minutes. Tissue masses such as injured ligaments or a bulging disc are not visible on conventional x-rays. Fluoroscopy is a type of x-ray that uses a continuous or pulsed beam of low-dose radiation to produce continuous images of a body part in motion. The fluoroscope x-ray tube is focused on the area of interest and pictures are either videotaped or sent to a monitor for viewing.

Fluoroscopy is used to evaluate swallowing and can be used for other procedures, such as a lumbar puncture, angiogram for clot removal, or myelogram. Scientists funded by the National Institute of Neurological Disorders and Stroke seek to develop additional and improved screening methods to more accurately and quickly confirm a specific diagnosis and investigate other factors that might contribute to disease.

Technological advances in imaging will allow researchers to better see inside the body, at less risk to the person. These diagnostics and procedures will continue to be important clinical research tools for confirming a neurological disorder, charting disease progression, and monitoring therapeutic effect.

Box Bethesda, MD April 10, Because the right kidney is just below the liver and left kidney below spleen. Liver being larger in size on right side pushes right kidney a little downward, but such an action is not taken by spleen because of its small size on left side.
