X-RAY OF TOE

X-ray Toe DP View

Toe AP (DP)

Region: phalanges, metatarsal bone

Pathology: fracture, dislocation and osteoarthritis (gouty arthritis, etc) of toe

SID: 100 cm (40 inches)

Central Ray: beam directed at the third metatarsophalangeal joint with 10~15˚ angulation toward calcaneus

Respiration: unrelated

Position:

1. The patient is placed either in a supine position or in a sitting position.
2. Flex knee to place the plantar on image receptor (IR), and place the filming toe on the center of IR.

Collimation: Include the phalanges to the distal portion of metatarsal bone.

Evaluation

1. Interphalangeal joint and metatarsophalangeal joint must be identifiable.
2. Each toe should not overlap and should be distinguishable with soft tissue.
3. The foot should not be rotated to make symmetry of phlanages and distal metatarsal bone.

X-ray Toe Lateral View

Region: phalanges, metatarsal bone

Pathology: fracture, dislocation and osteoarthritis of toe

SID: 100 cm (40 inches)

Central Ray:perpendicular beam directed at the metatarsophalangeal joint

Respiration: unrelated

Position:

1. The patient is placed either in a supine position or in a sitting position.

2. Rotate leg and foot, and apply gauze if needed to flex the lateral phalanges and extend the medial phalanges, and place the major axis of toes on the vertical axis of image receptor (IR).

Collimation:Include phalanges.

Evaluation:

1. Lesion suspected phalanges and soft tissue should not overlap.

2. Interphalangeal joint and metatarsophalangeal joint must be identifiable.

3. If the phalanges cannot be separated, the medial portion of the phalanges should be taken using the radiolucent blocks to separate them from the lateral portion of the phalanges.

kVp-55, mAs-2.5

Tip:

1. When high resolution is necessary, low kVp shooting or use of non-screen cassette, etc can be considered.
