Medical Imaging Techniques Quiz

Which medical imaging technique uses strong magnetic fields and radio waves to generate detailed images of the body's internal structures?

• X-ray

• Computed Tomography (CT)

• Magnetic Resonance Imaging (MRI)

• Ultrasound

What is the main advantage of ultrasound imaging compared to other medical imaging techniques?

• It does not use ionizing radiation

• It provides the highest image resolution

• It is the most expensive imaging method

• It is only used for brain scans

In diagnostic imaging, which of the following modalities is best suited for detecting bone fractures?

• MRI

• CT scan

• X-ray

• PET scan

Which factor is most important when interpreting medical imaging results?

• The brand of the imaging machine

• The experience of the radiologist or medical professional analyzing the image

• The patient's insurance coverage

• The number of images taken during the scan

What is the purpose of contrast agents in medical imaging?

• To enhance image clarity by making specific tissues or blood vessels more visible

• To reduce the cost of the imaging procedure

• To replace the need for radiation in X-ray and CT scans

• To eliminate the need for a trained radiologist

What is the primary difference between radiography (X-ray) and ultrasound imaging?

• X-ray uses ionizing radiation, while ultrasound uses sound waves

• X-ray provides real-time imaging, while ultrasound does not

• Ultrasound is only used for bone imaging, while X-ray is used for soft tissues

• X-ray is completely safe, while ultrasound has radiation risks

What is a limitation of radiography (X-ray) compared to ultrasound?

• X-ray cannot be used for diagnosing bone fractures

• X-ray exposes patients to ionizing radiation

• X-ray images have lower resolution than ultrasound images

• X-ray can only be performed in a standing position

What is the main disadvantage of ultrasound imaging?

• It cannot image soft tissues

• It cannot penetrate bone or air-filled structures, limiting its use in certain areas

• It is more dangerous than X-ray due to radiation exposure

• It cannot be used to examine the heart
