CAMRT UPDATED ACTUAL QUESTIONS
AND CORRECT ANSWERS
COMPREHENSIVE STUDY GUIDE
●● Endoscopic Retrograde Cholangiopancreatography; used to diagnose
biliary and pancreatic pathologies when the biliary ducts are not dilated
and no obstruction exists in the ampulla
Answer: What does ERCP stand for and what is it done for?
●● AP motility of the cervical spine, or lack of movement due to trauma
or disease
Answer: What do Flexion/Extension views of the Cervical Spine assess?
●● Must not exceed 2% of the SID
Answer: In SC35, what is the limit for light field and x-ray field
alignment?
●● Assist in detecting early radiologic changes needed to diagnose
rheumatoid arthritis
Answer: Why do we do a ball catcher's view?
●● Low blood pressure due to standing upright (dizziness after getting
up from a supine position)
,Answer: What is Orthostatic Hypotension?
●● Germicide is a solution that destroys microorganisms; Disinfectant is
a type of germicide that inhibits the growth of bacteria
Answer: What is the difference between Germicide and Disinfectant?
●● Scaphoid
Answer: Which carpal bone is most commonly fractured?
●● Lauenstein=lesser trochanter in profile medially and femoral neck
superimposes greater trochanter
Cross-table Lateral=femoral neck demonstrated without overlap from
greater trochanter and a small amount of the lesser trochanter on the
posterior surface of the femur demonstrated in profile
Answer: What is the difference between Lauenstein and cross-table
lateral views of the hip?
●● Allows accurate measurement for any type of vertebral displacement
or noticeable swelling that could suggest a disguised fracture
Answer: Why do we include anterior soft tissue on a trauma cross-table
lateral of the c-spine?
●● The long axis of the lower leg
,Answer: When imaging the intercondylar fossa, which body part is
perpendicular to the central ray?
●● 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
Answer: What is the purpose of lateral bending for scoliosis imaging?
●● 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
Answer: What is the optimal kV for a chest x-ray and why?
●● Angle less (closer to perpendicular) slightly or leave the tube
perpendicular so clavicles will be 1" below apices of lung
Answer: When doing a portable chest x-ray, how do you adjust the
central ray for a kyphotic patient?
●● 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
Answer: Why is a CT study for PE scanned from from abdomen to just
above shoulders?
, ●● Steroids and antihistamines (Benadryl, Medrol)
Answer: What type of medication may be administered to a patient prior
to a contrast study to prevent a reaction?
●● The ability of an imaging process to distinguish small, adjacent,
high-contrast structures in the object
Answer: What is Spatial Resolution?
●● 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
Answer: What should you do if a nurse forgets to chart a medication
during an Intravenous pyelogram (IVP)?
●● Recorded detail
Answer: What does penumbra effect?
●● 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)
Answer: What is the Line Focus Principle?
