A cranial CT scan is computed tomography of the head, including the skull, brain, orbits (eye sockets), and sinuses.

Electromyography is a test that assesses the health of the muscles and the nerves controlling the muscles.

Electromyography (EMG) is an electrical recording of muscle activity that aids in the diagnosis of neuromuscular disease. Purpose Muscles are stimulated by signals from nerve cells called motor neurons.

EMG and NCS TestsElectromyography(EMG)and nerve conduction studies(NCS)are tests that measure muscle and nerve function. In most cases, both tests are performed.

Electromyography (EMG) is used to detect, process, and record electrical muscle activity in order to aid in the diagnosis of neuromuscular disease. Purpose EMG is performed most often to help diagnose different neuromuscular diseases causing weakness.

Electromyography (EMG) is an electrical recording of muscle activity that aids in the diagnosis of neuromuscular disease, which affects muscle and peripheral nerves. Purpose Muscles are stimulated by signals from nerve cells called motor neurons.

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with hands; Auscultation (listening to sounds; Percussion (producing sounds.

Kidney function tests are common procedures used to evaluate renal function. Refer to the following documents for details of how each test is performed: Creatinine; Creatinine - urine; Creatinine clearance; BUN.

Kidney function tests are a cadre of tests that are used to screen for and manage renal disease. Tests commonly used for this purpose are plasma creatinine, blood urea nitrogen (BUN), electrolytes, and routine urinalysis .

Kidney function tests is a collective term for a variety of individual tests and procedures that can be done to evaluate how well the kidneys are functioning. A doctor who orders kidney function tests and uses the results to assess the functioning of the kidneys is called a nephrologist.

Kidney function tests is a collective term for a variety of individual tests and procedures that can be done to evaluate how well the kidneys are functioning. Purpose The kidneys, the body ' s natural filtration system, perform many vital functions, including removing metabolic waste products from the bloodstream, regulating the body ' s water balance, and maintaining the pH (acidity/alkalinity) of the body ' s fluids.

Liver function tests, or LFTs, include tests for bilirubin, a breakdown product of hemoglobin, and ammonia, a protein byproduct that is normally converted into urea by the liver before being excreted by the kidneys. LFTs also commonly include tests to measure levels of several enzymes, which are special proteins that help the body break down and use (metabolize) other substances.

Detailed information on the most common liver function tests, including serum bilirubin test, serum albumin test, serum alkaline phosphatase test, serum aminotransferases, prothrombin time test, alanine transaminase test, aspartate transaminase test, gamm

Liver function tests, or LFTs, include tests that are routinely measured in all clinical laboratories. LFTs include bilirubin, a compound formed by the catabolism of hemoglobin; ammonia, a product of protein catabolism that is normally converted into urea by the liver before being excreted by the kidneys ; proteins that are made by the liver including total protein, albumin, prothrombin, and fibrinogen; cholesterol and triglycerides, which are made and excreted via the liver; and the enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), and lactate dehydrogenase (LDH).

An MRI of the head is a noninvasive procedure that uses powerful magnets and radio waves to construct clear, detailed pictures of brain tissues. Conventional radiography and computed tomographic (CT) imaging use potentially harmful radiation (x-rays) that passes through a patient to generate images. Magnetic resonance imaging (MRI) is based on the magnetic properties of atoms, and there is no exposure to the same type of radiation used in x-rays and CT scans. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. Radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, returning a signal of their own. The slight differences of those signals from different tissues enables MRI to tell the difference between various organs, and potentially, provide contrast between benign and malignant tissue. Any imaging angle, or "slice", can be projected, and then stored in a computer or printed on film. MRI can easily be performed through clothing and bones. However, certain types of metal in or around the area of interest can cause significant errors in the reconstructed images. These errors are called artifacts.

A brain tumor is an abnormal growth of tissue, either malignant (cancerous) or benign (noncancerous), in the brain. Each year, more than 17,000 brain tumors are diagnosed in the United States.

The brain is the part of the central nervous system (CNS) inside the skull (the part outside the skull is the spinal cord ). It gives rise to cognitive thought processes and controls various body functions including muscular activity, speech, sight, hearing , breathing, and digestion.

Traumatic brain injury (TBI) is the result of physical trauma to the head causing damage to the brain. This damage can be focal, or restricted to a single area of the brain, or diffuse, affecting more than one region of the brain.

Magnetic resonance imaging (MRI) scanners rely on the principles of atomic nuclear-spin resonance. Using strong magnetic fields and radio waves, MRI collects and correlates deflections caused by atoms into images.

The brain is a large mass of soft nervous tissue made up of both neurons and supporting glial cells lying within the cranium of the skull. The brain contains both gray and white matter.

The brain is the part of the central nervous system located in the skull. It controls the mental processes and physical actions of a human being.

Congenital brain defects are a group of disorders of brain development. Brain development begins shortly after conception and continues throughout the growth of a fetus.

A brain tumor is an abnormal growth of tissue in the brain. Unlike other tumors, brain tumors spread by local extension and rarely metastasize (spread) outside the brain.

A brain biopsy is the removal of a small piece of brain tissue for the diagnosis of abnormalities of the brain, such as Alzheimer ' s disease , tumors, infection, or inflammation. Purpose By examining the tissue sample under a microscope, the biopsy sample provides doctors with the information necessary to guide diagnosis and treatment.

Brain abscess is a bacterial infection within the brain. The brain is usually well insulated from infection by bacteria, protected by the skull, the meninges (tissue layers surrounding the brain), the immune system, and the highly regulated barrier between the bloodstream and the brain.

Congenital brain defects are a group of disorders of brain development that are present at birth. Brain development begins shortly after conception and continues throughout the growth of a fetus.

Like all other parts of the body, the brain and central nervous system are made up of cells that ordinarily grow and divide to create new cells as needed. This is usually an orderly process; but when cells lose their ability to grow normally or to die off naturally, they divide too often and produce tumors that are made up of these extra cells.

Part of the central nervous system located in the skull. Controls mental and physical actions of the organism.

An ALT test measures the amount of the enzyme ALT in serum (the liquid part of the blood.

An AST blood test measures the amount of the enzyme AST.

The Aspartate aminotransferase test measures levels of AST, an enzyme released into the blood when certain organs or tissues, particularly the liver and heart, are injured. Aspartate aminotransferase (AST) is also known as serum glutamic oxaloacetic transaminase (SGOT).

Ceruloplasmin is a test that measures the amount of ceruloplasmin (a copper-containing protein) in blood serum.

Thyroid function tests are common tests used to tell how well your thyroid is working. See the following articles for details: T3; T3 resin uptake; T4; Thyroid scan; TSH; TSI.

Thyroid function tests are blood tests used to evaluate how effectively the thyroid gland is working. These tests include the thyroid-stimulating hormone test (TSH), the thyroxine test (T 4 ), the triiodothyronine test (T 3 ), the thyroxine-binding globulin test (TBG), the triiodothyro-nine resin uptake test (T 3 RU), and the long-acting thyroid stimulator test (LATS).

Detailed information on the most common types of thyroid function tests

The key tests to determine thyroid function are serum measurements of free thyroid hormones and thyroid-stimulating hormone (TSH). Thyroid hormones have a negative feedback on TSH secretion from the anterior pituitary.

Thyroid function tests are blood tests used to evaluate how effectively the thyroid gland is working. These tests include the thyroid-stimulating hormone test (TSH), free and total thyroxine tests (FT 4 ,T 4 ), the free and total triiodothyronine tests (FT 3 ,T 3 ), the thyroxine-binding globulin test (TBG), and the T-uptake test.
