An echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than a plain x-ray image and involves no radiation exposure.
|
 |
Echocardiography is a diagnostic test that uses ultrasound waves to create an image of the heart muscle. Ultrasound waves that rebound or echo off the heart can show the size, shape, and movement of the heart's valves and chambers as well as the f...

A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.
|
|
A chest x ray is a procedure used to evaluate organs and structures within the chest for symptoms of disease. Chest x rays include views of the lungs, heart, small portions of the gastrointestinal tract, thyroid gland and the bones of the chest ar...

An electrocardiogram (ECG) is a test that records the electrical activity of the heart. See also: Holter monitoring; Stress test.
|
|
Electrocardiography is a commonly used, noninvasive procedure for recording electrical changes in the heart. The record, which is called an electrocardiogram (ECG or EKG), shows the series of waves that relate to the electrical impulses that occur...
|
|
The electrocardiography unit, also called an electrocardiograph, is an apparatus that indirectly measures the heart's electrical activity and records it as a graphic tracing.
|
|
The electrocardiogram (ECG) displays important information about the heart, including the occurrence of a heart attack or lack of oxygen, whether conduction of the heartbeat is disturbed, or its rate or rhythm altered. It is useful as a rapid indi...

A pregnancy ultrasound is an imaging test that uses sound waves to see how a fetus is developing in the womb. It is also used to check the female pelvic organs during pregnancy.
|
|
Prenatal ultrasound is a procedure performed during pregnancy to obtain images of the fetus.
|
 |
Pelvic ultrasound is a procedure in which high-frequency sound waves create images of the pelvic organs. The sound waves are projected into the pelvis, and measure how they reflect—or echo—back from the different tissues.
|
 |
An ultrasound unit is a noninvasive medical device used to produce images of body tissues and organs from differential reflections of ultrasonic sound waves. The technique of diagnostic imaging performed by ultrasound units is called ultrasonograp...
|
|
Antenatal testing includes any diagnostic procedures performed before the birth of a baby.
|
|
Antenatal testing describes procedures performed during pregnancy to detect health problems in the growing fetus; establish characteristics such as fetal age, sex, or weight; or diagnose any material conditions that may affect fetal development.
|
 |
Pelvic ultrasound is a procedure in which high-frequency sound waves are used to create images of the pelvic organs by projecting the sound waves into the pelvis and measuring how the sound waves reflect, or echo, back from the different tissues.
|
 |
Ultrasound involves the use of high-frequency sound waves to create images of organs and systems within the body.
|
|
Ultrasonography is a diagnostic technique that involves directing high frequency sound waves at tissues in the body to generate images of anatomical structures. Ultrasonography is also called sonography, diagnostic sonography, and echocardiography...

A thyroid ultrasound, or sonogram, is a diagnostic imaging technique used to evaluate the structure of the thyroid gland . The thyroid is an endocrine gland, which means that it releases its secretions directly into the bloodstream or lymph. It co...

|
Ultrasonography is the study of internal organs or blood vessels using high-frequency sound waves. The actual test is called an ultrasound scan or sonogram. Duplex ultrasonography uses Doppler technology to study blood cells moving through major v...

 |
Diagnostic medical sonography, or ultrasound, is a technique using high frequency sound to create images of specific areas of the body to diagnose various pathologies. The diagnostic medical sonographer performs examinations, records anatomic cond...
|
|
The use of ultrasound to obtain diagnostic images is referred to as diagnostic sonography. Since diagnostic sonography utilizes a nonionizing form of energy, there are no known bioeffects. Thus, diagnostic sonography is applied to a large spectrum...

Cardiac catheterization involves passing a thin flexible tube (catheter) into the right or left side of the heart, usually from the groin or the arm.
|
 |
Cardiac catheterization (also called heart catheterization) is a diagnostic procedure which does a comprehensive examination of how the heart and its blood vessels function. One or more catheters is inserted through a peripheral blood vessel in th...
