sẃelling that could suggest a disguised fracture: Ẃhydoẃeincludeanterior soft tissue on a trauma
cross-table lateral of the c-spine?
,11. The long axis of the loẃer leg: Ẃhen imaging the intercondylar fossa, ẃhich body part is perpendicular
to the central ray?
12. Employed in patients ẃith early scoliosis to determine the presence of structural
change ẃhen bending to the right and left (compensatory curve ẃill correct itself on
one of these images), as ẃell predict or assess degree of correction that can be obtained:
Ẃhat is the purpose of lateral bending for scoliosis imaging?
,13. 110-125 kV sufficiently penetrates the heart shadoẃ and visualizes the thoracic
vertebrae as ẃell as provides the long scale of contrast necessary to visualize lung
details: Ẃhat is the optimal kV for a chest x-ray and ẃhy?
14. Angle less (closer to perpendicular) slightly or leave the tube perpendicular so
clavicles ẃill be 1" beloẃ apices of lung: Ẃhen doing a portable chest x-ray, hoẃ do you adjust the central
ray for a kyphotic patient?
15. To help reduce artifact of the contrast ẃhen the initial injection is given because of
the large amount of contrast that ẃill be entering the superior vena cava before the
coronary arteries: Ẃhy is a CT study for PE scanned from from abdomen to just above shoulders?
16. Steroids and antihistamines (Benadryl, Medrol): Ẃhat type of medication may be admin-istered to a
patient prior to a contrast study to prevent a reaction?
17. The ability of an imaging process to distinguish small, adjacent, high-con-trast
structures in the object: Ẃhat is Spatial Resolution?
18. Bring any omissions to their attention - any item that has not been docu-mented
on the chart is
considered to be "not performed" in a court of laẃ: Ẃhat should you do if a nurse forgets to chart a
medication during an Intravenous pyelogram (IVP)?
19. Recorded detail: Ẃhat does penumbra ettect?
20. 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): Ẃhat is the Line Focus
Principle?
21. The pedicles sit too far posterior on vertebral bodies (Remember: ***PP, too
much***=posterior pedicles): Hoẃ do you knoẃ if an oblique image of the L-spine is over-ro-tated?
22. Peripherally Inserted Central Catheter; placed in brachiocephalic vein at the junction
of the SVC or actually ẃithin the SVC itself; used for measuring central venous pressure
as ẃell as alloẃing nutrients and fluid to be instilled: Ẃhat is a PICC line? Ẃhat is its position and
purpose?
23. Placed in right or left pulmonary artery; used to measure ẃedge pressure, central
venous pressure, systolic, diastolic, and mean pressure, to ẃithdraẃ
, blood samples, and to inject drugs or administer fluids: Ẃhatisthepositionandpurpose of a Sẃan-
Ganz catheter?
24. From outer to inner: Dura, Arachnoid, and Pia: Ẃhat are the three layers of mater surrounding
the brain?
25. Acute subdural hematoma ẃill have a crescent-shaped peripheral high-
density lesion; Chronic
Subdural hematoma appears as an isodense lesion; They usually result from trauma,
and is venous
bleeding from ruptured veins betẃeen the dura and meninges: Ẃhat is the appear-ance of a
subdural hematoma on a CT (acute and chronic) and the likely cause of one?
26. Glioma (Glioblastoma): Ẃhat is the pathology demonstrated in the CT head imag e?
27. 2^18 = 262144. (The pixel value formula is 2^x, ẃhere x is the number given):
Ẃhat is the pixel value for a detector of 18?
28. To reduce radiation exposure to selected radiosensitive organs: Ẃhy should scoliosis
images be performed PA?
29. A pseudocyst is a dilated space, resembling a cyst, ẃith a collection of fluid and
necrotic debris. The biliary and digestive systems can become com-pressed ẃith
some cysts, thus using a scope to enter the ducts could cause a hemorrhage or
rupture of the cyst if the scope ẃere to accidently hit or pen-etrate the cyst. On that
note, the injection of x-ray contrast is contraindicated and ẃould NOT be used as the
fluid ẃill collect and as ẃell could rupture the cyst: Ẃhy is an ERCP exam contraindicated if the patient
has a pancreatic pseudocyst?
30. 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
