What is oblique view X-ray?
What is oblique view X-ray?
Oblique – Projection taken with the central ray at an angle to any of the body planes. Described by the angle of obliquity and the portion of the body the X-ray beam exits; right or left and posterior or anterior. For example, a 45 degree Right Anterior Oblique of the Cervical Spine.
Which position provides best view of the acetabular rim?
The iliac oblique projection should demonstrate the anterior rim of the acetabulum as well as the posterior ilioischial column. The iliac wing, as it is ‘flatten’ out on the image, should be well demonstrated.
What is the purpose of an oblique view in radiology?
The oblique hand view is requested for diagnosing a variety of clinical indications such as rheumatoid arthritis, osteoarthritis, suspected fracture or dislocation and localizing foreign bodies.
What is obturator oblique view?
Obturator oblique view is obtained on a supine patient with the injured side of the pelvis rotated anteriorly at 45°. The x-ray beam is directed vertically toward the affected hip. It is useful to assess the obturator ring, anterior column (iliopectineal line), and posterior wall of the acetabulum.
What is the meaning of oblique projection?
An oblique projection is a parallel projection in which the lines of sight are not perpendicular to the projection plane. Commonly used oblique projections orient the projection plane to be perpendicular to a coordinate axis, while moving the lines of sight to intersect two additional sides of the object.
What is the oblique position used for?
The lumbar spine oblique view is used to visualize the articular facets and pars interarticularis of the lumbar spine.
What direction does the acetabulum face?
The acetabulum is formed by the fusion of the ilium, ischium, and pubis. The acetabulum faces anteriorly and caudally. It averages 15 degrees of anteversion and 45 degrees of abduction.
What is an oblique pelvis?
The oblique pelvis otherwise known as the Judet view is an additional projection to the pelvic series when there is suspicion of an acetabular fracture.
What is the use of oblique projection?
Which is the oblique projection of the acetabulum?
The obturator oblique projection should distinctly show the posterior rim as well as the anterior ilioischial line. As per the name, the obturator foramen is well demonstrated. Practical points. The ‘Judet view’ is a two-part view of the acetabulum, the collimation of the Judet views is departmentally dependent.
Where is the radiograph of the acetabulum located?
The location on an anteroposterior radiograph of the anterior and posterior walls of the acetabulum. Figure 18.4. Axial CT scan through the acetabular tectum, showing the oblique orientation of a posterior wall fracture. Letournel and Judet described five basic or “elemental” patterns of acetabular fractures and five combined patterns.
Which is an example of an oblique view X ray?
Oblique – Projection taken with the central ray at an angle to any of the body planes. Described by the angle of obliquity and the portion of the body the X-ray beam exits; right or left and posterior or anterior. For example, a 45 degree Right Anterior Oblique of the Cervical Spine.

Where is the fracture in the acetabulum Foundation?
The iliac oblique view of the same case as shown above in AP and obturator oblique section. Evaluating the iliac oblique of our current example, we can see the level at which the fracture disrupts the posterior border (blue) of the bone is at the ischial spine.
