CAMRT COMPREHENSIVE EXAM
QUESTIONS AND CORRECT ANSWERS
STUDY GUIDE
●● Air gap technique
Answer: reduces scatter, increases contrast
IP 10-15 cm away from pt
mAs increase 10% for every cm gap
Not effective with high kV
●● why expiration with pneumo
Answer: reduces lung vol, pneumo occupies larger area- easier to see
●● Spondylolisthesis
Answer: forward displacement of a vertebra commonly occurs after #
(pars)
●● Spondylolysis
Answer: occurs when there is a fracture of the pars portion of the
vertebra.
●● Situs inverus
,Answer: organs on opposite side
●● dyspneic
Answer: SOB
●● hematuria
Answer: blood in urine
●● cystitis
Answer: bladder infection
●● judet
Answer: c: side in contact ant acetabular rim (external obl)
o: side raised post ace rim
●● T/z score
Answer: T: bone loss compared to peak (30 yr old)- assess # risk,
Osteoporosis
Z: compared to pts bmd of same age group + race
Normal: > -1
Osteo: <-2.5
,●● AP knee angle
Answer: 18 cm and less: 5 caudad
19-24cm: no angle
25cm +: 5 ceph
●● indication of ant hip dislocation
Answer: ext rotated foot
●● Outlet/ inlet
Answer: oulet: around 25-30 (men) 45 women ceph for rami
inlet: 40 caudad for pelvic ring
●● Lat Tspine if pt has big sholders
Answer: angle 10-15 ceph
●● Hypovolemic shock
Answer: fluid loss 15-25%
SS: cold and clammy, thirst, cyanosis
What to do: elevate legs( trendelenberg), keep warm
●● Ba Enema tips
, Answer: insert tube ant + sup
hang bag 46cm 18inch
24 hrs prior clear liquid diet
●● Stomach positions
Answer: GI position RAO: Ba in duodenal bulb, pyloric canal (also seen
in rt lat)
LPO: fundus
Lat: ant/post stomach, retrogastric space
PA: Ba in body and pylorus/ air in fundus
AP: Ba filled fundus and duodenum/jejunum
●● Ba Enema views
Answer: Shisard: PA (30 caud) Rectosigmoid
LPO/RAO: hepatic/colic flex, asc colon, sigmoid
RPO/LAO: splenic, desc
●● Aliasing/ Moire
Answer: wavy grid artifact
common with low freq stationary non moving grid
grid strips parallel with scan direction (should be perp)
