CXR
This is the area where the corners of the lungs & the diaphragm meet
What is Costophrenic angles?
To demonstrate the radial head free of superimposition, the arm should be placed in this specific oblique position.
What is a 45-degree lateral (external) rotation?
On an AP Pelvis, the feet are rotated 15-20 degrees medially to prevent this part of the femur from appearing foreshortened.
What is the femoral neck?
To compensate for the lordotic curvature of the neck and clearly demonstrate the intervertebral disk spaces on an AP Axial Cervical spine projection, the central ray must be adjusted to this specific angle and direction.
What is 15–20 degrees cephalad?
For an AP projection of the ribs above the diaphragm, the CR should be centered at this vertebral level.
What is T7?
What is Chest PA & Lateral?
This anatomical landmark is the required centering point for a standard PA projection of the hand.
What is the third metacarpophalangeal (MCP) joint?
This specific oblique of the foot is the only one that clearly demonstrates the cuboid and the sinus tarsi.
What is a medial oblique?
This anatomical figure, seen on an oblique lumbar spine radiograph, is formed by the parts of the vertebra and is used to evaluate the integrity of this specific bony bridge.
What is the Scotty Dog?
When performing a bilateral AC joint exam, the SID should be increased to this many inches to include both AC joints & reduce magnification.
What is 72 inches?
This is the primary reason for performing a PA (Posteroanterior) chest projection at a 72-inch Source-to-Image Distance (SID).
What is "To decrease magnification of the heart and increase recorded detail?"
This projection is performed to see the "fat pads" of the elbow, which can indicate hidden fractures.
What is a true lateral elbow (flexed 90 degrees)?
To open the IP and MTP joint spaces of the toes on an AP projection when the foot is placed flat on the IR, the central ray must be adjusted to this specific angle and direction.
What is 15 degrees cephalad?
In a lateral projection of the thoracic spine, this breathing technique is used to blur out overlying rib and lung markings.
What is an orthostatic breathing technique?
To demonstrate the right axillary ribs, the patient should be placed in this specific oblique position.
What is the LAO (Left Anterior Oblique)?
This is to demonstrate the presence of air-fluid levels in the chest of a patient who cannot stand or sit upright.
What is Decubitus positions/views?
For an AP projection of the shoulder, the central ray should be centered 1 inch inferior to this palpable landmark.
What is the coracoid process?
For a lateral knee radiograph, the CR is angled 5-7 degrees cephalad entering 1' distal from this anatomical structure to prevent from obscuring the joint space.
What is the medial femoral epicondyle?
This is the name of the position used to view the cervicothoracic junction when the shoulders are superimposed
What is the Swimmer’s view (Twining method)?
This is the specific breathing instruction given to a patient for an AP or PA projection of the ribs above the diaphragm to move the diaphragm to its lowest level.
What is "Suspend on full inspiration"?
This is for a routine PA chest projection, the central ray (CR) should be directed perpendicular to the image receptor and centered at the level of:
What is "T7 or inferior angle of the scapula?"
This "letter-shaped" projection is used to diagnose shoulder dislocations in trauma patients.
What is the Scapular Y?
The mortise view of the ankle requires the leg and foot to be rotated internally this many degrees.
What is 15 to 20 degrees?
To demonstrate the sacroiliac (SI) joints, the patient is rotated this many degrees into an oblique position.
What is 25 to 30 degrees?
In an AP projection of the shoulder with external rotation, these two anatomical structures are seen in profile on the lateral aspect of the humerus.
What are the greater tubercle and the humeral head?
