Lecture 1 - Clinical View

Question 1

Traditional X-ray images continue to play a major role in medical diagnoses involving
bone and abnormal dense structures, such as a tumor.

Answer 1

X-Ray Imagining

Question 2

Produces improved X-ray images that are computer enhanced for clarity.

Answer 2

Computed tomography (CT) or computed axial tomography (CAT)

Question 3

An imaging technique that uses low-dose radiation to examine the breast for tumors.

Answer 3

Mammography

Question 4

An imaging technique that utilizes a contrast medium injected into a blood vessel to produce clear images of blood vessels. Angiography is important for diagnosing diseases and disorders of blood vessels.

Answer 4

Angiography

Question 5

Provides an unobstructed view of small arteries. Images of vessels are taken before and after injection of contrast medium. Computer technology allows for the “before” image to be “subtracted,” yielding clear images of potential blockages in vessels to the heart or brain.

Answer 5

Digital subtraction angiography (DSA)

Question 6

Tracks radioisotopes in the body, locating areas of high energy consumption and high blood flow.

Answer 6

Positron emission tomography (PET)

Question 7

Provides sonar images of developing fetuses and internal body structures, such as an enlarged liver.

Answer 7

Sonography (ultrasound imaging)

Question 8

Subjects the body to strong magnetic fields and radio waves, producing high-contrast images of soft body parts.

Answer 8

Magnetic resonance imaging (MRI)
