RTP Final Exam With
Complete Solution
All AP views of the LE you do what? - ANSWER IR 5-15°
What extremity views require grid? - ANSWER Above knee and above the
elbow
What TFD do all extremities start at? - ANSWER 40"
What are the standard hip series? - ANSWER AP hip and frogleg
AP Hip: Purpose - ANSWER Taken as part of a standard hip series to obtain
a frontal view of the iliofemoral joint
AP Hip: Patient Measurement - ANSWER AP, through the iliofemoral joint
AP Hip: Grid? - ANSWER Yes, stationary or moveable
AP Hip: SID - ANSWER 40"
AP Hip: Tube tilt - ANSWER None
AP Hip: Image Receptor Size - ANSWER 10"x12"
-Portrait
AP Hip: Patient Positioning - ANSWER The pt stand upright or lies
recumbent with the posterior aspect of the affected iliofemoral region
touching the grid and centered to the image receptor.
-If no hip fx is suspected, the LE on the affected side is IR approximately 15°,
,with the second digit of the foot pointing straight forward (upright) or
straight up (recumbent)
AP Hip: Central Ray Position - ANSWER Through the hip joint,
approximately 1" below the midpoint between the ASIS and symphysis pubis
on the affected side
AP Hip: Collimation - ANSWER To the size and orientation of the image
receptor
AP Hip: Marker Placement - ANSWER The marker used corresponds to the
hip being imaged
-It is placed directly on the image receptor, in one of the corners, without
superimposing anatomy
AP Hip: Shielding - ANSWER None
AP Hip: Breathing Instructions - ANSWER "Don't breath, and don't move"
-Suspended respiration and motion
Frogleg Hip: Purpose - ANSWER Taken as part of a standard hip series to
obtain an opposing view of the femur for assessment of the iliofemoral joint
-A true lateral view would not be helpful, due to the overlying anatomy of
the pelvis and contralateral hip
Should the frogleg view be performed if a fx is suspected? - ANSWER No
Frogleg Hip: Pt Measurement - ANSWER AP, through the iliofemoral joint
Frogleg Hip: Grid - ANSWER Yes, stationary or moveable
Frogleg Hip: SID - ANSWER 40"
,Frogleg Hip: Tube tilt - ANSWER None
Frogleg Hip: Image Receptor Size - ANSWER 10"x12"
-Portrait orientation
Frogleg Hip: Patient Positioning - ANSWER The pt stands upright or lies
recumbent with the posterior aspect of the affected iliofemoral region
touching the grid and centered to the image receptor.
-If performed upright, the pt should have a stable object or piece of furniture
nearby for stabilization
-The knee and hip are both flexed to approximately 90° and the hip is fully
abducted with the lateral aspect of the knee touching the grid
Frogleg Hip: Central Ray Position - ANSWER Through the hip joint,
approximately 1" below the midpoint between the ASIS and symphysis pubis
on the affected side
Frogleg Hip: Marker placement - ANSWER The marker used corresponds to
the hip being imaged. It is placed directly on the image receptor, in one of
the corners, without superimposing anatomy
Frogleg Hip: Shielding - ANSWER None
Frogleg Hip: Breathing Instrucitons - ANSWER "Don't breath, and don't
move"
-Suspended respiration and motion
What are the standard knee views? - ANSWER -AP knee
-Lateral knee
, -Tunnel View
AP Knee: Purpose - ANSWER Taken as part of a standard knee series to
obtain a frontal view of the knee joint.
If a patella fx or pathology is suspected, what series is preferred? - ANSWER
Patella, for greater detail and less knee flexion, which helps to prevent
separation of the fx fragments
AP Knee: Pt measurement - ANSWER AP, through the knee joint 1/2" distal
to the apex of the patella
AP Knee: Grid? - ANSWER A grid should be used only if the knee measures
greater than 10-14 cm
AP Knee: SID - ANSWER 39"
AP Knee: Tube Tilt - ANSWER 5° cephalic for smaller patients
-For larger patients 0-5° caudal
AP Knee: Image receptor size - ANSWER The smallest image receptor
available
-Portrait orientation
AP Knee: Patient. Positioning - ANSWER The pt stands upright or lies
recumbent with the posterior aspect of the affected knee touching the image
receptor/grid and centered to the image receptor.
-The LE of the affected side is IR ~15°, with the second digit of the foot
