CAMRT Exam Study Set 2026/2027 |
Updated Study Guide | High-Yield Notes &
Practice Tests
Small pneumothorax: what additional image to the routine pictures? - correct
answer-PA inspiration, PA expiration, Lateral (or lateral decub with affected lung
UP)
AEC not recommeneded - for expiration should be increased by 1/3 of that used
for inspiration images
Pneumothorax picture in PA inspo: what additional image to the routine pictures?
- correct answer-PA Expiration....
or lateral decub with affected lung up (air rising to the highest point in the
hemithorax is more clearly visible then on erect views)
Shoulder AEC hard soft tissue differentiation - what factors to adjust? - correct
answer-WINDOW WIDTH (narrower)
smaller ww to enhance the amount of blacks and whites showing up so you can
see the small differences in similar HU
What is the best position + SID for highest spatial resolution for C-spine obliques?
RAO - correct answer-PA (reduce dose) (LAO RAO), long SID (180cm)
,Trauma: AP Caldwell with IOML perpendicular, how much angulation? - correct
answer-8 cephalic (to compensate for the OML)
What is seen on CT of an intracranial SOL? - correct answer-Midline shift
OR
ventricle compression
SOL = space occupying lesion
Pregnant worker already with 1mSv irradiated, how much for the remainder of
the pregnancy? (declared at 3 months?) - correct answer-4msv total
3msv for remainder of pregnancy
Projection for orbits: - correct answer-(AP 15 Axial, PA 15 Axial, PA 30 Axial, AP 30
Axial)
Modified waters (modified parietoacanthial projection) best projection
TMJ image - angulation? - correct answer-Axiolateral projection (Schuller
method): 25-30 caudad - center 1.3cm anterior and 5cm superior to upside EAM
Axiolateral oblique projection (Modified law method): 15 degree caudal angle -
center 1.5inch superior to upside EAM
AP axial projection (modified towne): angle 35-degrees caudad from OML OR 42-
degrees from IOML - center 3inches superior to nasion.
Mandible image - how much was it turned (body is well demonstrated?) - correct
answer-30 toward IR
, (45 degree rotation demonstrates mentum, 10-15 degree rotation provides a
general survey of the mandible, true lateral demonstrates the ramus)
Pelvis ischial spine not superimposed over the pelvic rim - closer to acetabulum -
which way is it rotated? - correct answer-LPO or RPO
If the left ischial spine is demonstrated w/o pelvic brim superimposition then it is
superimposed on the right acetabulum. left obturator foramen more
foreshortened than right.
In pelvis rotation, the upside will have ischial spine superimposition over the
acetabulum.
Maxillary sinus opacified, what pathology is most likely? - correct answer-Blowout
fracture- pretty freaking sure
"opacification of the sinus caused by hemorrhage and mucosal edema is an
indirect sign of..this"
OR sinusitis
Increase HVL = tungsten vaporization? come back to this one. - correct answer-
HVL is the thickness of a designated absorber required to decrease the intensity
of the primary beam by half its original value.
an xray beam of 3-4.5mm aluminium is considered acceptable when kVp ranges
from 80-100.
Increased skin dose, inadequate filtration to reduce the beam to half, leakage
radiation
Optimal image of pelvis - - correct answer-75-85 kVp, outer cells, grid,
