Roles of imaging modalities Flashcards
What is the primary role of X-ray imaging?
X-rays are used to view and diagnose conditions related to bones, teeth, and chest, including fractures, infections, and lung diseases.
What is the primary role of CT scans?
CT scans provide detailed cross-sectional images of the body, helping in the diagnosis of conditions affecting bones, blood vessels, and soft tissues. They are especially useful in detecting cancers, cardiovascular diseases, and internal injuries.
What is the primary role of MRI?
MRI is used to produce detailed images of organs and tissues, particularly useful in diagnosing brain and spinal cord conditions, joint abnormalities, and soft tissue tumors.
What is the primary role of ultrasound imaging?
Ultrasound uses high-frequency sound waves to create images of the inside of the body, commonly used in obstetrics for fetal monitoring, as well as for examining organs like the liver, kidneys, and heart.
What is the primary role of PET scans?
PET scans are used to observe metabolic processes in the body, helping to detect cancer, evaluate brain function, and assess heart disease.
What is the primary role of fluoroscopy?
Fluoroscopy provides real-time moving images of the internal structures of the body, useful in guiding procedures like catheter insertion, joint injections, and gastrointestinal examinations.
What is the primary role of mammography?
Mammography is specifically used for the early detection and diagnosis of breast cancer by capturing detailed images of breast tissue.
What is the primary role of nuclear medicine imaging?
Nuclear medicine involves using small amounts of radioactive materials to diagnose and treat diseases, particularly useful for evaluating organ function and detecting cancer, heart disease, and thyroid disorders.
What is the primary role of angiography?
Angiography is used to visualize the inside of blood vessels and organs of the body, particularly useful for detecting blockages and abnormalities in the arteries and veins.
What is the primary role of DEXA scans? (Dual-Energy X-ray Absorptiometry)
DEXA scans are used to measure bone mineral density, helping to diagnose and monitor osteoporosis.
What is the primary role of an echocardiogram?
An echocardiogram uses ultrasound to create images of the heart, helping to diagnose heart conditions and evaluate heart function.
What is the primary role of thermography?
Thermography measures the heat emitted by the body’s surface and is used for early detection of abnormal changes in tissue, such as inflammation or tumors.
