Upper Extremity
The greater tubercle of the Humerus will be in profile laterally when the hand is in this position.
What is External Rotation
This is the optimal amount of tube angle used for the axial calcaneus view and the point of entry for the CR
What is 40 degrees cephalad, enetring the base of the 3rd metatarsal
Especially if the patient is unable to stand, this is the best patient position to demonstrate free air in the abdomen.
What is a left lateral decubitus position
This is the typical tube angle we use for an AP view of the coccyx.
What is 10 degrees caudad
When obtaining a “Shallow Waters” view for Pre-MRI orbits, positioning the patient’s head with the “Top of Ear Attachment” and “Infraorbital Margin” lined up parallel to the central ray will place the petrous ridges here on the image.
What is just below the inferior orbital rim
This is the thicker of the 2 borders of the scapula.
What is the lateral border
For the PA Intercondylar Fossa (Holmblad) projection, this is the patient position and CR angle
Lower leg against IR, femur 70 degree from IR, CR perpendicular to tib/fib entering the posterior popliteal fossa
During a KUB exam, if the patient has recently had a lithotripsy performed and has not had imaging since, this view is added to the routine.
What is an AP oblique image (20-30 degrees, affected side down)
Oblique C-spine views are the most effective radiographic views to demonstrate stenosis of this anatomical feature.
What is the intervertebral foramen
This is the tube angle required for an AP “towne” view when performing a facial bones routine
What is 30 degrees caudad
If unable to obtain an external oblique elbow image to rule out a radial head fracture, what should the radiographer do and how?
The Coyle method: Elbow flexed 90 degrees, tube angled 45 degrees toward the shoulder
What anatomical features are well visualized on a medial oblique foot?
2nd - 5th Open metatarsal bases, tuberosity at base of 5th metatarsal, sinus tarsi, cuboid free of superimposition
These are 3 of the 4 reasons why we would perform a Dual Energy Chest X-ray.
What is PICC placement, TB, ribs, and granulomatous disease
If a patient presents with atlanto-axial subluxation, on a flexed lateral C-spine image we will see a larger than normal space between the anterior arch of C1 and this bony anatomical feature.
What is the odontoid process/dens
When positioning for a submento-vertical/basal view of the facial bones, we line up this anatomical line perpendicular to the central ray for optimal imaging.
What is IOML
This is the proper positioning of the hand in relation to the wrist for the a scaphoid or navicular view.
What is ulnar deviation
This indicates a perfect lateral foot
superimposed metatarsal heads
When performing portable CXR imaging with a standard 6:1 grid on an average sized patient, this is the amount of kVp that should be used.
What is 120
This cervical spine view will best demonstrate a Jefferson’s fracture.
What is the open-mouth odontoid/dens view
When obtaining a water’s view for facial bones, this anatomical line is parallel to the central ray.
What is MML (Mentomeatal line)
Exactly how do you perform the PA oblique scapular Y-View on a right shoulder?
45 - 60 degree RAO until the lateral and medial borders of the scapula are superimposed, arm can hang down,
CR is perpendicular, entering the medial border of the scapula at the scapulohumeral joint
How does the central ray differ from a lateral foot, ankle and calcaneus?
Foot = base of 3rd metatarsal
Ankle = enters medial malleolus
Calcaneus = 1 inch distal to the medial malleolus
DAILY DOUBLE!!!
Where is the tip of this malpositioned PICC likely located?
A hangman’s fracture will most commonly affect the pars interarticularis bilaterally on this cervical vertebra.
What is C2 (axis)
Placing the OML (a.k.a. radiographic baseline) parallel to the central ray will allow us to obtain this skull view.
