Arteriography is a procedure in which a contrast material that can be seen using x-ray equipment is injected into one of the arteries, allowing your health care provider to see the vessel.

Angiography is the x-ray (radiographic) study of the blood vessels. An angiogram uses a radiopaque substance, or contrast medium, to make the blood vessels visible under x ray.

Angiography is a special type of x-ray that allows your coronary arteries to be viewed and recorded on film. Your doctor can see if the blood vessels to your heart are clogged.

Computed Tomography Angiography (CTA)CTAcreates images of arteries throughout the body. Acontrast medium(x-ray dye) is injected to make the blood vessels stand out.

Peripheral AngioplastyTalk to your doctor about the risks and complications of angioplasty.Peripheral angioplasty is a procedure that helps open blockages in peripheral arteries. These vessels carry blood to your lower body and legs.Before the Pro...

Hepatic AngiographyHepatic angiographyis an x-ray study of the blood vessels that supply the liver. The procedure uses acatheter(thin, flexible tube) that is placed into a blood vessel through a small incision.

Audiometry is the testing of a person ' s ability to hear various sound frequencies. The test is performed with the use of electronic equipment called an audiometer.

Audiometry is performed to test a person's ability to hear the sound frequencies necessary for speech. The test is carried out by a trained specialist called an audiologist with an instrument called an audiometer.

Audiometry encompasses those procedures used to measure hearing thresholds. Purpose The purpose of audiometry is to establish an individual ' s range of hearing.

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

Head injury is an injury to the scalp, skull, or brain. The most important consequence of head trauma is traumatic brain injury.

Injury to the head may damage the scalp, skull or brain. The most important consequence of head trauma is traumatic brain injury.

Computed tomography (also known as CT, CT scan, CAT, or computerized axial tomography) scans use x rays to produce precise cross-sectional images of anatomical structures. With the development of modern computers, the scans enhanced digital capabilities allowed the development of computed tomography imaging (derived from the Greek tomos , meaning " to slice " ).

CT imaging equipment includes conventional, spiral, multi-slice, and electron-beam computed tomography full-body scanners, which use x rays to acquire cross-sectional images and computer workstations to reconstruct acquired image data for display on a viewing monitor or printed on film. Also referred to as computerized axial tomography (CAT) scanning equipment.

Computed tomography (CT) scans are completed with the use of a 360-degree x-ray beam and computer production of images. These scans allow for cross- sectional views of body organs and tissues.

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)

A physical examination is an evaluation of the body and its functions using inspection, palpation (feeling with the hands), percussion (tapping with the fingers), and auscultation (listening). A complete health assessment also includes gathering information about a person ' s medical history and lifestyle, doing laboratory tests, and screening for disease.

The health history is a current collection of organized information unique to the individual patient. Relevant aspects of the history include biographical, demographic, physical, mental, emotional, sociocultural, sexual, and spiritual data.

The skull x-ray is used to examine the bones of the skull, including the facial bones, the nose, and the sinuses. See also sinuses x-ray .

An MRI of the head is a non-invasive procedure that uses powerful magnets and radio waves to construct clear, detailed pictures of brain tissues. Unlike conventional radiography and computed tomography (CT), which make use of potentially harmful x-rays passing through a patient to generate images, MRI imaging is based on the magnetic properties of atoms. 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. The "nuclear" in the original name (nuclear magnetic resonance imaging) -- now seldom used -- refers to the proton in the nucleus of the hydrogen atom and does not imply radioactivity. When focused short radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, they will return a signal of their own. The subtle differences in that signal from dissimilar tissues enables the MRI to differentiate between various organs, and potentially, provide contrast between benign and malignant (cancerous) tissue. Any imaging plane, or slice, can be projected, and then stored in a computer or printed on film. MRI is easily 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.
