Which type of pathologic feature is best demonstrated with the Judet method?
Chapter 8
| Question | Answer |
|---|---|
| What type of pathologic feature is best demonstrated with the Judet method? | Acetabulum fracture |
| How much obliquity of the body is required for the Judet method? | 45 degrees |

What is Teufel method?
Hip Acetabulum PA Axial Oblique Teufel Method Have patient suspend respiration for exposure. Position of part Align body, and center hip being examined to midline of grid. Elevate unaffected side so that the anterior surface of the body forms a 38 degree angle from table.
What is XR pelvis?
X-ray – pelvis. A pelvis x-ray is a picture of the bones around both the hips. The pelvis connects the legs to the body. The sacrum is a shield-shaped bony structure that is located at the base of the lumbar vertebrae and that is connected to the pelvis.
How does the Judet view the pelvis?
- patient is supine.
- the affected side is rotated roughly 45° anterior, generally aided by a 45° sponge.
- central beam directed vertically toward the affected hip.
- ensure the patient is central on the table and at no risk of over rolling.
How do you get the Judet view?
Patient position
- patient is supine.
- the unaffected side is rotated roughly 45° anterior, generally aided by a 45° sponge.
- central beam directed vertically toward the affected hip.
- it is advisable that the patient is positioned central on the table and at no risk of over-rolling.
Which projection of the foot will best demonstrate the longitudinal arch?
Chapter 7
| Question | Answer |
|---|---|
| A patient comes to radiology for an evaluation of the longitudinal arch of the foot. What projection would provide the best information about the arch? | Lateral weight bearing projection |
What is another name for the Judet method?
The oblique internal and external pelvis views otherwise known as the Judet view are additional projections to the pelvic series when there is suspicion of an acetabular fracture.
What is the central ray for Clements Nakayama modification?
Central Ray: Angle the central ray mediolaterally as needed so that it is perpendicular to and centered to femoral neck of approximately 15 to 20 degrees posteriorly from horizontal.
What is best demonstrated in Clements Nakayama for the wrist?
Wrist Trapezium PA Axial Oblique Clements-Nakayama Method Purpose and Structures Shown: This view should demonstrate the bones and soft tissue of hand including the carpals, metacarpals, phalanges. No rotation of the hand should be observed.
What does Judet mean?
Judet view. judgment. Judgment of Line Orientation Test.
What is the Ilioischial line?
The ilioischial line demarcates the medial border of the posterior column. The posterior wall of the acetabulum is larger and projects more laterally than does the anterior wall.
What is a Judet view?
(zhū-dā’), view consisting of two oblique radiographic projections centered on the hip in question, tilted 45° medially or laterally from a true anteroposterior direction; useful for fractures or deformities of the acetabulum.
Why do we do Judet view?
Which projection of the foot will demonstrate the head of the first metatarsal equally superimposed by two sesamoid bones?
It is common to see two sesamoid bones on the posterior surface of the head of the 1st metatarsal. These bones should be centered over the metatarsal head on an AP or dorsoplantar projection of the foot.
What is the main advantage of the Lateromedial projection of the foot?
Chapter 7
| Question | Answer |
|---|---|
| What is one advantage of the lateromedial projection of the foot? | The foot assumes a more true lateral position |
| What CR angulation is required for the AP oblique projection of the foot? | CR is perpendicular to the film |
Which projection of the wrist elongates the scaphoid and shortens the capitate?
PA in ulnar deviation This elongated position of scaphoid allows for easier detection of scaphoid fractures. [8] The scaphoid can also be brought out to length much more by extending the wrist by 20° or by angling the beam towards the wrist by 20° [Figure 4].
