Quiz 1 Flashcards
Asthenic
A slight build with long, narrow, shallow thorax, which is wider more superiorly
Hypersthenic
Massive, truncated build with short, broad, deep thorax
Hyposthenic
A build somewhere between asthenic and sthenic
Sthenic
Average with respect to height, weight, and torso length
CT or MRI
In general, it is better at imaging compact bone
CT
CT or MRI
It is better at demonstrating microfractures
MRI
CT or MRI
Ferromagnetic objects in or near patients are problematic
MRI
CT or MRI
Generally, it involves less scanning time
CT
CT or MRI
It has better tolerance for patient motion
CT
CT or MRI
It is a less expensive sectional imaging option
CT
CT or MRI
It offers low-contrast resolution
MRI
CT or MRI
Almost all images are acquired transaxially
CT
CT or MRI
Contrast media is gadolinium based.
MRI
CT Or MRI
It relies on hydrogen atoms in the body as part of the imaging process
MRI
CT or MRI
Contrast media is iodinated (ionic or nonionic) or barium sulfate.
CT
CT or MRI
Images are “weighted” by Pd (protein density), T1 relaxation times, or T2 relaxation times.
MRI
Ct or MRI
The ALARA (as low as reasonably achievable) concept is promoted.
CT
True or false
Non-ionic iodinated contrast injections in CT will result in fewer contrast reactions compared to ionic iodinated contrast injections.
True
True or false
The term cephalad means toward the tail end of the spine.
False
True or false
The term caudal means toward the tail end of the spine
True
True or false
The terms posterior and dorsal are synonyms.
True
True or false
A person in the anatomic position is standing face forward, with palms of hands facing posteriorly.
False
True or false
The sectional imaging modality preferred for head trauma is CT, as it can demonstrate skull and/or facial features as well as brain injury.
True
True or false
The term courted means towards the meet.
False
The presence of ferromagnetic objects in the body or in MRI scanning room can pose a safety hazard for those having an MRI.
True
Which build is massive and truncated, with a short, broad, and deep thorax?
Hypersthenic
True or false
The term medial means towards the midline of the body.
True
True or false
A midsagittal (or median)plane runs vertically or longitudinally from front to back through the midline of the body, dividing the body equally into right and left parts.
True
Which build is average with respect to height, weight, and torso length?
Sthenic
True or false
Those with an asthenic body habitus have a slight build with along, narrow, and shallow thorax that is wider more superiorly.
True
The term distal means
Farther from the point of attachment
True or false
Both the cranial and spinal cavities are located posteriorly.
True
True or false
A sagittal plane runs vertically or longitudinally from front to back parallel to the median plane, dividing the body into right and left parts.
True
True or false
Those with a hyosthenic build have a build somewhere between asthenic and sthenic.
True
True or false
Those with a hyosthenic build have a build somewhere between asthenic and sthenic.
True
True or false
In CT imagine, the X-ray beam is parallel to the part being imaged.
True
The term supine means
Lying on the back, face upward.
