Medical imaging
techniques and procedures used to create images of the human body
Medical Imaging
The grandparent of all medical imaging techniques is
Radiography
Which imaging technique uses A single barrage of x-rays passes through the body, producing an image of interior structures on x-ray–sensitive film.
Radiography
Which technique is useful for examining soft tissue?
Mammography
Which technique is used to determine bone density?
Bone densitometry or DEXA scan
Substance used to make hollow or fluid-filled structures visible (appear white)
Contrast medium
Contrast xrays are used to image blood vessels. This is called a/an
Angiography
Contrast xrays are used to image the urinary system
Intravenous urography
Contrast xrays used to image the gastrointestinal tract is called a/an
Barium contrast xray
The grandparent of all medical imaging techniques is
conventional radiography (x-rays)
A single barrage of x-rays passes through the body, producing an image of interior structures on x-ray–sensitive film.
Radiography
useful for examining soft tissues such as the breast (mammography) and for determining bone density (bone densitometry or DEXA scan).
radiography
It is necessary to use a substance called a ___ to make hollow or fluid-filled structures visible (appear white) in radiographs.
contrast medium
used to image blood vessels
angiography
used to image the urinary system
intravenous urography
used to image gastrointestinal tract
(barium contrast x-ray)
Which imaging techniques is used here?
Angiography
What type of scan is used here?
Bone densitometry
_______ of female breast showing cancerous tumor (white mass with uneven border)
Mammogram
What type of imaging technique is used here?
Radiography
This is a _____ showing kidney stone (arrow) in right kidney.
Intravenous urogram
_____ showing cancer of the ascending colon. (Which imaging technique)
Barium contrast xray
The body is exposed to a high-energy magnetic field, which causes protons (small positive particles within atoms, such as hydrogen) in body fluids and tissues to arrange themselves in relation to the field. Then a pulse of radio waves “reads” these ion patterns, and a color-coded image is assembled on a video monitor. The result is a two- or three-dimensional blueprint of cellular chemistry.
(Which imaging technique is described here?)
Magnetic Resonance Imaging
What does MRI stand for?
Magnetic Reasonance Imaging
Which imaging technique cannot be used on patients with metal in their body?
MRI
Which imaging technique shows fine details for soft tissues but not for bones?
MRI
Which imaging technique is most useful for differentiating between normal and abnormal tissues?
MRI
Used to detect tumors and artery-clogging fatty plaques; reveal brain abnormalities; measure blood flow; and detect a variety of musculoskeletal, liver, and kidney disorders.
MRI
Which imaging technique is shown here?
MRI
In this form of computer-assisted radiography, an x-ray beam traces an arc at multiple angles around a section of the body.
Computed Tomography (CT)
