Question 1

&#10;&#10;-Refer to the figure. Name the projection.&#10;A) Anteroposterior&#10;B) Lateral&#10;C) External oblique&#10;D) Internal oblique

Accepted Answer

The projection is a lateral projection, which is used to view the body or body part from the side.

Question 2

&#10;&#10;-A soft tissue sign associated with the projection in the question 1 figure is known as the fat pad sign. A positive fat pad sign is caused by:&#10;A) Increased capsular volume&#10;B) Extra adipose tissue&#10;C) Poor radiographic positioning&#10;D) Artifact

Accepted Answer

A positive fat pad sign is indicative of increased capsular volume, often due to joint effusion or hemorrhage, which displaces the fat pad and makes it visible on radiographs.

Question 3

&#10;&#10;-A positive fat pad sign at the elbow would be correlated with what clinical finding?&#10;A) Fractured forearm&#10;B) Swollen elbow joint&#10;C) Absent biceps contour&#10;D) Triceps pain

Accepted Answer

A positive fat pad sign at the elbow is indicative of an effusion within the elbow joint, which leads to swelling of the joint. This sign is often associated with intra-articular fractures but can also be seen in other conditions causing joint effusion.

Question 4

&#10;&#10;-An abnormal supinator line seen on the lateral radiograph of the elbow is a reliable soft tissue sign of an underlying:&#10;A) Radial head fracture&#10;B) Proximal ulna fracture&#10;C) Medial epicondyle fracture&#10;D) Lateral epicondyle fracture

Accepted Answer

An abnormal supinator line on a lateral elbow radiograph suggests a disruption in the normal relationship between the radial head and the capitellum, which is most commonly associated with a radial head fracture. This radiographic sign is used to infer the presence of such fractures, especially when the fracture itself may not be directly visible.

Question 5

&#10;&#10;-An abnormal supinator sign seen on the elbow radiograph would most likely be correlated with what mechanism of injury?&#10;A) Overuse in pitching&#10;B) Painting a house&#10;C) Fall on an outstretched hand&#10;D) Rheumatoid exacerbation

Accepted Answer

An abnormal supinator sign is typically associated with a radial head fracture, which is commonly caused by a fall on an outstretched hand. This mechanism of injury applies direct force to the elbow, potentially leading to such fractures.

Question 6

&#10;&#10;-Refer to the figure. Name the imaging modality and plane.&#10;A) Anteroposterior MRI&#10;B) Coronal MRI&#10;C) Sagittal MRI&#10;D) Axial MRI

Accepted Answer

The imaging modality is MRI, and the plane shown is coronal, which divides the body into anterior (front) and posterior (back) parts.

Question 7

Refer to the figure. Is this a T1-weighted image or a fluid-sensitive T2-weighted image?  &#10;A) T1&#10;B) T2

Accepted Answer

The answer of Refer to the figure. Is this a...

Question 8

&#10;&#10;-Refer to the figure. The increased edema at the origin of the common flexor tendon indicated by the arrow suggests:&#10;A) Medial epicondyle fracture&#10;B) Lateral epicondyle fracture&#10;C) Medial epicondylitis&#10;D) Lateral epicondylitis

Accepted Answer

The increased edema at the origin of the common flexor tendon, as indicated by the arrow, suggests medial epicondylitis, often referred to as "golfer's elbow." This condition is characterized by pain and inflammation on the inner side of the elbow, where the tendons of the forearm muscles attach to the bony bump on the inside of the elbow (the medial epicondyle).

Question 9

Radiographic evaluation of elbow trauma from a fall on an outstretched hand usually includes additional views of the:&#10;A) Shoulder&#10;B) Metacarpals&#10;C) Forearm and wrist&#10;D) Acromioclavicular joint

Accepted Answer

When a patient falls on an outstretched hand, the force of the fall can transmit through the forearm and wrist, potentially causing injuries in these areas. Therefore, radiographic evaluation often includes additional views of the forearm and wrist to assess for any associated injuries.

Question 10

Loose fracture fragments in the elbow joint can be difficult to see within the joint capsule. The best imaging morality to locate these fragments is:&#10;A) Computed tomography&#10;B) Magnetic resonance imaging&#10;C) Bone scan&#10;D) Ultrasound

Accepted Answer

Computed tomography (CT) is the best imaging modality for locating loose fracture fragments in the elbow joint because it provides high-resolution images of bone details, allowing for the precise identification and localization of these fragments.
