- Evaluating conditions related to the ovaries and uterus.
Fill in the blank:
Ultrasound is used in cardiology to perform ______ to assess heart function and structure.
echocardiograms
True or False:
Ultrasound uses ionizing radiation.
False
What is a limitation of ultrasound imaging?
Limited penetration, making it less effective for imaging structures deep within the body or in patients with significant obesity.
What is the primary use of X-ray machines?
Uses ionizing radiation to create images of the internal structures of the body.
Which imaging technique is primarily used to detect fractures and bone infections?
X-rays
Select the correct answer:
Which of the following is a safety consideration for X-ray imaging?
A. Use of contrast media
B. Radiation exposure
C. Claustrophobia
D. Limited penetration
B. Radiation exposure
What preparation might be required before an X-ray exam?
- Patients may be asked to change into a hospital gown.
- Avoid wearing jewelry or clothing with metal fasteners.
Fill in the blank:
A CT scan uses ______ to create detailed cross-sectional images of the body.
X-rays
List two applications of CT scans in trauma assessment.
- Quickly evaluates injuries to the head, chest, abdomen, and pelvis after accidents.
- Assists in diagnosing lung diseases, including pulmonary embolism and infections.
What is a key safety consideration when using CT scans?
Radiation exposure, as CT scans expose patients to higher levels of radiation compared to standard X-rays.
What is the primary function of MRI machines?
Uses powerful magnets, radio waves, and a computer to create detailed images of the organs and tissues within the body.
Which imaging technique is used in neurology to diagnose brain conditions such as tumors and strokes?
MRI
True or False:
MRI uses ionizing radiation.
False
What is a safety consideration for patients with metal implants undergoing an MRI?
The strong magnetic field can attract ferrous metal objects and pose risks; patients must inform healthcare providers about any implanted devices.
What preparation is typically required before an MRI exam?
- Patients are asked to wear loose-fitting clothing without metal fasteners.
- All jewelry, watches, and metallic objects must be removed.
