Nuclear medicine & Pharmacology
Exam With Correct Answers Graded A+
Three most common imaging techniques used to visualize and examine body
structures
Radiography, computed tomography, and magnetic resonance imaging
Radiography
Uses x-radiation passing through the patient to expose a film or create a digital image
that shows the body in profile. In the resulting film, hard tissues are light, soft tissues are
shades of gray, and air is black
Computed tomography
Uses X-radiation with computer assistance to produce multiple cross-sectional views of
the body. Hard tissues are light, and soft tissues are light, and soft tissues appear as
shades of gray
Magnetic resonance imaging
Uses a combination of radio waves and a strong magnetic field to produce images.
Hard tissues are dark, and soft tissues appear as shades of gray
Radiopaque
Means that the substance does not allow x-rays to pass through and appears white or
gray on the resulting film
Radiolucent
Means that the substance such as air or nitrogen gas, allows X-rays to pass through
and appears black or dark gray on the resulting film
Intravenous contrast medium
Injected into a vein to make the flow of blood through blood vessels and organs visible
Barium
A radiopaque contrast medium used primarily to visualize the gastrointestinal tract
Radiography and fluoroscopy
Used to trace the flow of the barium
Radiologist
A physician who specializes in diagnosing and treating diseases and disorders with x-
rays and other forms of radiant energy
Tomography
The use of x-rays or ultrasound to produce a cross-section of the body
Tomography scan
, Uses a thin, fan-shaped x-ray beam that rotates around the patient to produce multiple
cross-sectional views of the body
Magnetic resonance imaging (MRI)
Uses a combination of radio waves and a strong magnetic field to create signals that
are sent to a computer and converted into images of any plane through the body
Fluoroscopy
The visualization of body parts in motion by projecting x-ray images on a luminous
fluorescent screen
Cineradiography
The recording of the fluoroscopy images
Ultrasonography
Imaging of deep body structures by recording the echoes of sound wave pulses that are
above the range of human hearing
Sonogram
The image created by ultrasonography
Echocardiography
An ultrasonic diagnostic procedure used to evaluate the structures and motion of the
heart
Transesophageal echocardiography
An ultrasonic imaging technique used to evaluate heart structures
Scintigram
A diagnostic procedure that uses nuclear medicine technology to gather information
about the structure and function of organs or body systems that cannot be seen on
conventional x-rays
Bone scan
A nuclear scanning test that identifies new areas of bone growth or breakdown
Thyroid scan
A radiopharmaceutical containing radioactive iodine is administered
Single photon emission computed tomography (SPECT)
A type of nuclear imaging test that produces 3D computer-reconstructed images
showing perfusion through tissues and organs
Perfusion
The flow of blood through an organ
Positron emission tomography (PET)
Combines tomography with radionuclide tracers, usually inserted into a vein, to produce
enhanced images of selected body organs or areas
Pharmacology
The study of the nature, uses, and effects of drugs for medical purposes
Pharmacist
A licensed specialist who formulates and dispenses prescribed medications
