Radiology Terminology and Concepts Quiz

CT scan stands for Computed Tomography, which utilizes X-rays and computer processing to create detailed cross-sectional images of the body.

MRI, or Magnetic Resonance Imaging, is commonly used in radiology for detecting brain tumors by capturing detailed images of the brain's soft tissues.

Radiography is the process in radiology that utilizes X-rays to create detailed images of the body's internal structures, commonly used for diagnostic purposes.

PET scan stands for Positron Emission Tomography, a radiology technique that involves injecting a radioactive tracer to measure the metabolic activity of tissues.

Mammography in radiology refers to the imaging of the breasts, commonly used for breast cancer screening and diagnosis.

In radiology, a tumor refers to an abnormal mass of tissue that grows within an organ, and it can be visualized through various imaging techniques.

Ultrasound is an imaging technique in radiology that uses sound waves to produce images of structures within the body, commonly used for examining organs and unborn fetuses.

Ultrasonography is the process in radiology that involves producing images of the body's internal structures using high-frequency sound waves, creating real-time visualizations.

DICOM stands for Digital Imaging and Communication in Medicine, providing a standardized format for the storage and transmission of medical images in radiology.

Angiography in radiology is primarily used for visualizing blood vessels, often involving the injection of a contrast dye to enhance visibility.

In radiology, a contrast agent is a substance that helps distinguish between different tissues or fluids in the body, enhancing the visibility of specific structures in imaging.

Teleradiology refers to the transmission of medical images for interpretation and consultation, often performed remotely.

In radiology, Hounsfield units measure the attenuation of X-rays by tissue, providing information about tissue density in CT scans.
