Wrist Imaging Techniques and Protocols

The video tutorial covers wrist positioning techniques for radiographic imaging. It begins with setting up the patient and equipment, including the use of a lead apron and adjusting the SID. The tutorial then explains how to center over the mid carpal region and collimate appropriately. It provides detailed instructions for positioning the wrist in PA, oblique, lateral, and scaphoid views, including the use of sponges for support and angling the tube for the scaphoid view.

What is the correct seating position for a patient during wrist imaging?

• Standing at a 45-degree angle

• Seated at a 90-degree angle from the table

• Seated at a 45-degree angle from the table

• Lying down flat on the table

Why is a lead apron placed over the patient's lap during wrist imaging?

• To keep the patient warm

• To protect the patient from radiation

• To stabilize the patient's wrist

• To improve image quality

What is the correct SID setting for tabletop wrist imaging?

• 30 inches

• 50 inches

• 40 inches

• 60 inches

Where should the left marker be placed during wrist imaging?

• On the medial side

• On the posterior side

• On the anterior side

• On the lateral side

What angle should the wrist be positioned at for an oblique view?

• 30 degrees

• 60 degrees

• 45 degrees

• 90 degrees

What is the purpose of using a sponge during oblique wrist positioning?

• To support the wrist

• To reduce radiation exposure

• To enhance image contrast

• To mark the wrist position

In a lateral wrist position, what should be ensured about the radius and ulna?

• They are perpendicular to each other

• They are at a 45-degree angle to each other

• They are superimposed over each other

• They are parallel to each other

What is the key feature of a true lateral wrist position?

• The wrist is rotated 90 degrees

• The hand is flat on the table

• The elbow is bent at 45 degrees

• The radius and ulna are superimposed

How should the tube be angled for a scaphoid view?

• 5 to 10 degrees towards the elbow

• 15 to 20 degrees towards the elbow

• 20 to 25 degrees towards the elbow

• 10 to 15 degrees towards the elbow

In the scaphoid view, how should the hand be positioned?

• Raised above the table

• Flat on the table

• Turned towards the pinky

• Turned towards the thumb
