Hand Radiography Techniques and Positions

The video tutorial demonstrates three hand radiograph techniques: PA, oblique, and lateral. Each technique involves specific patient positioning, image receptor placement, and collimation to ensure clear visualization of hand anatomy, including phalanges, metacarpals, carpals, and distal radius and ulna. The tutorial emphasizes the importance of avoiding motion and rotation for diagnostic quality images.

What is the correct position for the patient's arm during a PA hand radiograph?

• Arm resting on the side

• Arm extended with elbow straight

• Arm at a 90-degree angle with elbow bent

• Arm raised above the head

Where should the centering be done for a PA hand radiograph?

• At the elbow joint

• At the thumb

• At the third metacarpophalangeal joint

• At the wrist joint

What is the key wrist position for an oblique hand radiograph?

• Wrist turned 90 degrees

• Wrist turned 45 degrees

• Wrist straight

• Wrist turned 30 degrees

During an oblique hand radiograph, how should the fingers be positioned?

• Fingers should be curled

• Fingers should be in a fist

• Fingers should be separated

• Fingers should be touching each other

What is the purpose of the fan lateral technique in a lateral hand radiograph?

• To show the palm clearly

• To visualize fractures and foreign bodies

• To highlight the thumb

• To reduce exposure time

How should the little finger be positioned in a lateral hand radiograph?

• Hidden behind the other fingers

• Bent towards the thumb

• Kept out and visible

• Tucked under the palm

What is the importance of collimation in a lateral hand radiograph?

• To reduce patient discomfort

• To enhance color contrast

• To ensure all digits are visible

• To shorten the exposure time

What must a diagnostic lateral hand radiograph be free of?

• Color distortion

• Excessive brightness

• Background noise

• Motion and rotation

Which anatomical structures should be visible in a diagnostic lateral hand radiograph?

• Only the phalanges

• Only the metacarpals

• Phalanges, metacarpals, carpals, distal radius, and ulna

• Only the carpals

What is the source to image distance for all hand radiographs discussed?

• 60 inches

• 50 inches

• 40 inches

• 30 inches
