Question

vocabulary understanding

using the term and definitions, match the term to the correct definition.

tomography _______

• electromagnetic waves used to produce a picture of internal structures of the body
• a detailed cross-section of tissue is produced.
• a study that displays images of body areas by recording and displaying the images for evaluation
• an ultrasound used to study the structures of the heart
• radio frequency signals used to examine the soft tissue and bony structures of the body without radiation

Explanation:

Analyze the medical term

The term to define is "Tomography". Etymologically, "tomo-" comes from the Greek word tomos, meaning "slice" or "section", and "-graphy" means "process of recording" or "writing". Therefore, tomography refers to an imaging technique that produces a detailed image of a slice or cross-section of the body.

Evaluate the given definitions

Let us evaluate each option against our Medical Vocabulary knowledge:

• Option 1: "Electromagnetic waves used to produce a picture of internal structures of the body" describes standard X-rays (radiography).
• Option 2: "A detailed cross-section of tissue is produced" aligns perfectly with the etymology of tomography (imaging by sections).
• Option 3: "A study that displays images of body areas by recording and displaying the images for evaluation" is a broad definition of general diagnostic imaging or fluoroscopy/ultrasound depending on context.
• Option 4: "An ultrasound used to study the structures of the heart" defines echocardiography.
• Option 5: "Radio frequency signals used to examine the soft tissue and bony structures of the body without radiation" defines Magnetic Resonance Imaging (MRI).

Select the correct match

The second option, "A detailed cross-section of tissue is produced," is the correct definition for tomography.

Answer:

• Electromagnetic waves used to produce a picture of internal structures of the body
• A detailed cross-section of tissue is produced. (Correct answer)
• A study that displays images of body areas by recording and displaying the images for evaluation
• An ultrasound used to study the structures of the heart
• Radio frequency signals used to examine the soft tissue and bony structures of the body without radiation
