I am the largest carpal bone and serve as the center of wrist articulation.

What is the capitate?

  • Largest carpal bone
  • Central bone of the distal carpal row
  • Articulates with the third metacarpal
  • Helpful landmark when identifying wrist anatomy
200

This injury mechanism is abbreviated "FOOSH."

What is a Fall On an Out Stretched Hand?

  • Common cause of scaphoid fractures
200

Instead of memorizing projections, always ask yourself this question first.

What anatomy needs to be demonstrated?

  • Anatomy drives projection selection
  • Think clinically
  • Avoid memorization without understanding
200

This digestive organ is responsible for absorbing most nutrients.

What is the small intestine, specifically the jejunum?

  • Longest portion of the small intestine

200

This joint is formed by the articulation of the trochlea and the trochlear notch.

What is the humeroulnar joint?

Talking Points

  • Primary hinge joint of the elbow.
  • Responsible for flexion and extension.
400

I am the only carpal bone that does not directly articulate with the radius.

What is the pisiform?

  • Lies anterior to the triquetrum
  • Easily identified on semisupinated wrist views
400

This structure often becomes more prominent on an AP pelvis when the legs are not internally rotated.

What is the lesser trochanter?

  • Indicates inadequate internal rotation (in non-trauma patients)
  • Femoral neck becomes foreshortened
400

You notice the physician ordered an AP shoulder, but the patient is holding the arm tightly against the body and grimacing in pain. Before attempting positioning, what should you do?

What is assess the patient's ability to move and determine whether trauma modifications are needed?

  • Observe before touching the patient.
  • Never assume routine positioning is appropriate.
  • Plan before moving the patient.
400

This portion of the large intestine begins immediately after the ileocecal valve.

What is the cecum?

  • First portion of the colon
  • Appendix originates here
400

This joint is formed by the articulation of the talus with both the tibia and fibula and is best demonstrated with the mortise projection.

Answer

What is the talocrural (ankle mortise) joint?

Talking Points

  • Weight-bearing hinge joint.
  • Mortise projection opens the entire joint space.
  • Critical for evaluating ligament injuries and ankle fractures.
  • Even slight rotation can obscure portions of the joint.
600

I am the cavity that receives the femoral head.

What is the acetabulum?

  • Socket of the hip joint
  • Formed by the ilium, ischium, and pubis
  • Important in acetabular fractures
  • Evaluated with Judet projections
600

This breathing instruction allows visualization of air-fluid levels in the abdomen.

What is suspended expiration?

  • Elevates the diaphragm
  • Improves demonstration of free air
  • Standard for upright abdomen
600

A patient says, "I can't do what you want because my shoulder hurts too much."

What should your next response be?

What is "Show me how far you can comfortably move your arm."

  • Let the patient demonstrate their range of motion.
  • Work within their tolerance.
  • Avoid forcing movement.
600

This contrast study is specifically designed to evaluate the mucosal surface of the colon.

What is a double-contrast barium enema?

  • High-density barium plus air
  • Excellent for polyps and small lesions
  • Better mucosal detail than single contrast
600

This carpal bone articulates with both the radius and the capitate, making it a key bone in transmitting forces through the wrist.

What is the lunate?

  • Central bone of the proximal carpal row.
  • Articulates with the radius proximally and the capitate distally.
  • Second most commonly fractured carpal bone.
  • Dislocation of the lunate is an orthopedic emergency because it can compress the median nerve.
800

I separate the thoracic cavity from the abdominal cavity.

What is the diaphragm?

  • Primary muscle of respiration
  • Inspiration lowers the diaphragm
  • Expiration elevates the diaphragm
800

This projection is often best demonstrates a shoulder dislocation.

What is the Scapular Y projection?

  • Demonstrates anterior vs posterior dislocation
  • Often performed before attempting reduction
  • Less painful than an axillary projection
800

If the physician wants to evaluate a specific ligament or joint, what should guide your choice of projection?

What anatomy must be placed in profile or opened?

  • Projection choice depends on anatomy
  • Not every projection is routine
  • Tailor imaging to the clinical question
800

Changing the patient's position during fluoroscopy changes this.

What is the distribution of barium and air?

  • Gravity affects contrast movement
  • Essential concept in GI imaging
  • Helps visualize different anatomy
800

This articulation between the radius and ulna allows the hand to rotate from a palm-up to a palm-down position.

What is the proximal radioulnar joint?

  • Responsible for pronation and supination of the forearm.
  • Best demonstrated on the AP oblique elbow with external rotation.
  • Injuries to this joint can limit forearm rotation even when flexion and extension are normal.
1000

I am the sphincter that prevents reflux from the stomach into the esophagus.

What is the cardiac (lower esophageal) sphincter?

  • Helps prevent GERD
  • Located at the gastroesophageal junction
  • Frequently evaluated during Upper GI studies
1000

This digestive study is usually the first fluoroscopic examination performed when swallowing difficulty is the chief complaint.

What is an esophagram (barium swallow)?

  • Evaluates swallowing mechanics
  • Assesses strictures, diverticula, reflux
  • May precede an Upper GI
1000

The best repeat image is the one that corrects this

What is the (positioning) error?

  • Analyze before repeating
  • Identify what went wrong
1000

 This is the last portion of the small intestine before entering the large bowel.

What is the ileum?

  • Ends at the ileocecal valve
  • Often the endpoint of a small bowel series
1000

This articulation is formed by the femoral condyles and the tibial plateau and is the primary weight-bearing joint of the lower extremity.

What is the tibiofemoral (knee) joint?

  • The largest synovial joint in the body.
  • Primarily allows flexion and extension with slight rotation.
  • Routine AP and lateral knee projections evaluate this articulation.
  • Trauma, arthritis, and ligament injuries commonly affect this joint.
