spine, or lack of movement due to trauma or disease
In SC35, what is the limit for light field and x-ray field alignment? - Must not exceed 2% of

small amount of the lesser trochanter on the posterior surface of the femur demonstrated in
profile

accurate measurement for any type of vertebral displacement or noticeable swelling that
could suggest a disguised fracture
When imaging the intercondylar fossa, which body part is perpendicular to the central ray? -
The long axis of the lower leg
What is the purpose of lateral bending for scoliosis imaging? - Employed in patients with
early scoliosis to determine the presence of structural change when bending to the right and
left (compensatory curve will correct itself on one of these images), as well predict or assess
degree of correction that can be obtained
What is the optimal kV for a chest x-ray and why? - 110-125 kV sufficiently penetrates the
heart shadow and visualizes the thoracic vertebrae as well as provides the long scale of
contrast necessary to visualize lung details
When doing a portable chest x-ray, how do you adjust the central ray for a kyphotic patient? -
Angle less (closer to perpendicular) slightly or leave the tube perpendicular so clavicles will
be 1" below apices of lung
Why is a CT study for PE scanned from from abdomen to just above shoulders? - To help
reduce artifact of the contrast when the initial injection is given because of the large amount
of contrast that will be entering the superior vena cava before the coronary arteries

a reaction? - Steroids and antihistamines (Benadryl, Medrol)

What is Spatial Resolution? - The ability of an imaging process to distinguish small, adjacent,
high-contrast structures in the object
What should you do if a nurse forgets to chart a medication during an Intravenous pyelogram
(IVP)? - Bring any omissions to their attention - any item that has not been documented on
the chart is
considered to be "not performed" in a court of law
What does penumbra effect? - Recorded detail
What is the Line Focus Principle? - Through angling the target, the effective area of the target
is made much smaller than the actual area of electron interaction (smaller anode
angle=smaller effective focal spot, larger anode angle=larger effective focal spot)

far posterior on vertebral bodies (Remember: ***PP, too much***=posterior pedicles)
What is a PICC line? What is its position and purpose? - Peripherally Inserted Central
Catheter; placed in brachiocephalic vein at the junction of the SVC or actually within the
SVC itself; used for measuring central venous pressure as well as allowing nutrients and fluid
to be instilled
What is the position and purpose of a Swan-Ganz catheter? - Placed in right or left pulmonary
artery; used to measure wedge pressure, central venous pressure, systolic, diastolic, and mean
pressure, to withdraw blood samples, and to inject drugs or administer fluids

Arachnoid, and Pia
What is the appearance of a subdural hematoma on a CT (acute and chronic) and the likely
cause of one? - Acute subdural hematoma will have a crescent-shaped peripheral high-density

venous
bleeding from ruptured veins between the dura and meninges
What is the pathology demonstrated in the CT head image? - Glioma (Glioblastoma)
What is the pixel value for a detector of 18? - 2^18 = 262144. (The pixel value formula is
2^x, where x is the number given)
Why should scoliosis images be performed PA? - To reduce radiation exposure to selected
radiosensitive organs
Why is an ERCP exam contraindicated if the patient has a pancreatic pseudocyst? - A
pseudocyst is a dilated space, resembling a cyst, with a collection of fluid and necrotic debris.
The biliary and digestive systems can become compressed with some cysts, thus using a
scope to enter the ducts could cause a hemorrhage or rupture of the cyst if the scope were to
accidently hit or penetrate the cyst. On that note, the injection of x-ray contrast is
contraindicated and would NOT be used as the fluid will collect and as well could rupture the
cyst
What is demonstrated on a 15-degree occipitofrontal view of the sinuses? - Frontal sinuses
lying superior to the frontonasal suture, anterior ethmoidal air cells lying on each side of the
nasal fossas and immediately inferior to the frontal sinuses, sphenoid sinuses projected
through the nasal fossas just inferior to or in between the ethmoid air cells, and petrous ridges
lying in the lower third of the orbits

What is the difference between Spondylolysis and Spondylolisthesis? - Spondylolysis=the
breaking down of a vertebra, or replacement of a portion of the vertebral arch with cartilage;
refers to a defect in the pars interarticularis without displacement; Spondylolisthesis=forward
displacement of a vertebra over a lower segment, usually of the 4 th or 5 th lumbar,
frequently due to spondylolysis

with proximal and lateral subluxation of metacarpal shaft that extends into first
