Radiology 1--Introduction

Front 1

fluoroscopy, very general desc

Back 1

similar to plain radiography, continuous image, often used w/ contrast agent

Front 2

nuclear medicine

Back 2

use gamma rays to create images, generally functional rather than anatomical info

Front 3

angiography

Back 3

uses x rays to make image, iodinated contrast dye injected into vessel, images before and after contrast to subtract all except vessels.

Front 4

how to make a nuclear medicine image

Back 4

1) chemically attach the radioactive isotope to a chemical (radiopharmaceutical) 2) the agent chosen determines where the isotope goes 3) camera is a detecter which detects incoming gamma rays from body

Front 5

Positron emission tomography

Back 5

1) When e+ hits e-, two photons in opposite directinos 2) images use glucose analog 18-FDG 3) PET looks at metabolic rate

Front 6

Magnetic Resonance Imaging

Back 6

1) No ionizing radiation 2) uses magnetic fields 3) gadolinium used as contrast 4) like NMR

Front 7

Ultrasound

Back 7

1) images w/ sound, 2) tissue interfaces reflect sound) 3) can use micro bubbles for contrast

Front 8

Radiology modalities that use ionizing radiation

Back 8

Plain films; fluoroscopy; computed tomography; angiography; nuclear medicine; positron emssion tomography

Front 9

modalities using x rays

Back 9

plain films; fluoroscopy; computed tomography; angiography

Front 10

modalities using gama rays

Back 10

nuclear medicine; positron emission tomography

Front 11

modalities using magnetic properties

Back 11

magnetic resonance imaging

Front 12

modalities using sound waves

Back 12

ultrasound

Front 13

common contrast agents

Back 13

Flouroscopy: Barium//Angiography:iodinated contrast // CT: Oral (barium) IV (iodinated) // MRI: gadolinium // Nuclear medicine: radiopharmaceuticals // ultrasound: microbubbles (not commmon)
