Radiology Practice Test

Which of the following is a primary use of CT scans?

1. Evaluating brain function

2. Detecting fractured bones

3. Monitoring blood flow

4. Assessing skin lesions

The correct answer is: Detecting fractured bones

CT scans, or computed tomography scans, are particularly effective in detecting fractured bones due to their ability to provide detailed cross-sectional images of the body. This imaging technique utilizes X-ray technology in combination with computer processing to create high-resolution images that can reveal complex bone structures, subtle fractures, and even small joint abnormalities that may not be visible on standard X-rays. While evaluating brain function, monitoring blood flow, and assessing skin lesions are important areas in medical imaging, they are not the primary use of CT scans. MRI and ultrasound are more often utilized for assessing soft tissue structures such as brain tissue, blood vessels, and skin lesions. Therefore, the capability of CT scans to clearly depict bony structures makes them invaluable for diagnosing fractures in various parts of the body.
