Overview of Diagnostic Imaging

These flashcards cover key concepts and terminology related to diagnostic imaging as discussed in the lecture.

Diagnostic Imaging

An adjunct to history and physical examination that provides helpful diagnostic information.

Radiologist

Artifact

A change in appearance of the image that distorts actual anatomical findings.

Contrast

The difference in brightness between an area of interest and surrounding tissues in imaging.

Planar Imaging

Shadows of three-dimensional objects presented in a two-dimensional image.

Cross-Sectional Imaging

Multiple two-dimensional images taken as slices through the area of interest, providing detailed views.

Doppler Ultrasound

A technique that measures blood flow by determining the direction and speed of blood flow through sound waves.

Echocardiogram

An ultrasound-based diagnostic tool used to evaluate heart structure and function.

Computed Tomography (CT)

An advanced form of mammography that creates three-dimensional images of the breast.

MRI (Magnetic Resonance Imaging)

An imaging technique that uses magnetic fields and radio waves to produce detailed images of organs and tissues.

Ultrasound (Sonogram)

An imaging modality that uses sound waves to create images of organs and structures inside the body.

Fluoroscopy

An imaging technique that allows the visualization of dynamic processes in real-time using a continuous x-ray beam.
