Imaging

Question 1

Injection of a radiopaque substance during cardiac catheterization for the purpose of imaging the heart and related structures.

Answer 1

Angiocardiography

Question 2

Threading of a catheter (thin tube) into the heart under fluoroscopic guidance to collect diagnostic information about structures in the heart, coronary arteries, and great vessels; also used to aid in treatment of CAD, congenital abnormalities, and HF.

Answer 2

Cardiac Catheterization

Question 3

Digital imaging process wherein contrast images are used to “subtract” the noncontrast image of surrounding structures, leaving only a clear image of blood vessels.

Answer 3

Digital Subtraction Angiography (DSA)

Question 4

Use of ultrasonic waves directed through the heart to study the structure and motion of the heart. Transesophageal echocardiography (TEE) images the heart through a transducer introduced into the esophagus.

Answer 4

Echocardiography (ECHO)

Question 5

Recording of electrical impulses of the heart as wave deflections of a needle on an instrument called an electrocardiograph. The record, or recording, is called an electrocardigram.

Answer 5

Electrocardiography (ECG, EKG)

Question 6

Imaging of the heart during exercise on a treadmill; may include the use of radioactive substance. Also called an exercise electrocardiogram.

Answer 6

Exercise Stress Test (EST)

Question 7

Special kind of x-ray procedure that allows visualization of structures in real time directly on a monitor screen.

Answer 7

Fluoroscopy

Question 8

Portable electrocardiograph that is worn to record the reaction of the heart to daily activities.

Answer 8

Holter monitor

Question 9

Computerized imaging that uses radiofrequency pulses in a magnetic field to detect areas of MI, stenoses, and areas of blood flow.

Answer 9

Magnetic Resonance Imaging (MRI)

Question 10

Multiple-gated acquisition scan is a noninvasive method of imaging a beating heart by tagging RBCs with a radioactive substance. A gamma camera captures the outline of the chambers of the heart as the blood passes through them.

Answer 10

MUGA Scan

Question 11

Use of radionuclide to diagnose CAD, valvular or congenital heart disease, and cardiomyopathy.

Answer 11

Myocardial Perfusion Imaging

Question 12

X-ray imaging of a vein after the introduction of a contrast dye.

Answer 12

Phlebography

Question 13

Computerized nuclear medicine procedure that uses inhaled or injected radioactive substances to help identify how much a patient will benefit from revascularization procedures.

Answer 13

Positron Emission Tomography (PET)

Question 14

Posteroanterior and lateral chest x-ray that may be used to evaluate the size and shape of the heart

Answer 14

Radiography

Question 15

Long, thin cardiac catheter with a tiny balloon at the tip that is fed into the femoral artery near the groin and extended up to the LV. This instrument then is used to determine LV function by measuring pulmonary capillary wedge pressure.

Answer 15

Swan-Ganz Catheter
