Radiography
A Chest x-ray is predominantly utilized to evaluate for pathology within this organ
What are the Lungs?
Most ultrasound examinations ordered in emergency department require the patient to be in this positions.
What is supine?
What is radiography (x-ray) or ultrasound?
MRI machines contain a very large version of this common houshold object, which may be found on a metal refrigerator door.
What is magnet?
This medical imaging modality is rapidley performed, usually within a few seconds
What is radiography (x-ray)?
This bone pathology, which commonly results from trauma, is well evaluted on x-ray.
What is a Fracture (broken bone)?
Patients with right upper adminional pain may undergo ultrasound to evaluate for pathology of this organ.
What is gallbladder?
CT utlizes ionizing radiation to form pictures, similar to this type of medical imaging modality.
What is radiography (x-ray)?
MRI does not use ionizing radioation, similar to this other medical imaging modality.
What is ultrasound?
Emergency room providers may order or perform thsi common and relatively quick examination to assist in diagnosis, which utlilizes no inonizing radioation.
What is ultrasound?
X-rays that have traveled through the patient form an image on this part of the x-ray machine.
What is the x-ray screen?
Ultrasound ultilizes this form of energy to produce images
What is sound energy?
Patietns may need to drink this substance 60-90 minutes prior to CT scanning of the abdomen and pelvis in order to improve evaluation of the bowel.
What is oral contrast?
This substance may prove hazardous by becoming a projectile if worn near or in the MIR scanner.
What is metal (or jewlry)?
This imaging modality ultilzes no inonizing radiation, but is not considered a first-line imaging study because it is realatively time-consuming and costly.
What is magnetic resonance imaging (MRI)?
The part of the x-ray machine transmits x-rays towards the patient
What is the x-ray generator?
This part of the ultrasound machine transmits high-frequency sound waves into the patient
What is the ultrasound probe?
Patietn smay need to be injected with this substance immediately prior to CT scanning in order ot improve evaluation of the organs and vessels.
What is intravenous (IV) contrast?
This is the average length of time for an MRI examination
What is 30 minutes?
Exposure to this form of radiation is minimized because of its ability to chemically modify molecules within the body, which may be harmful at high doses.
What is ionizing radiation?
This term refers to the proprensity fo body tissues to absorve x-rays before they reach the x-ray screen
What is attenuation?
Daily Double! This term refers to the degree to whcih different tissues reflect sound waves traveling through the body.
What is acoustic impedence?
CT scans are usually completed within this length of time in an emergent setting.
What is 30 seconds?
Daily Double! Similar to CT, MRI uses information derived during scanning to form these types of images, which improves evaluation by avoiding overlap of adjacent structures
What are cross-sectional images?
This principle is employed when obtaining diagnostic imaging to iminimize radiation dose
What is ALARA (AS LOw as reasonably achievable)
