A true mediolateral projection of the ankle is evidenced by:

superimposition of the medial and lateral malleoli
inclusion of the base of the 5th metatarsal
dorsiflexion of the foot
the distal fibula superimposed over the posterior half of the tibia

Question 2

Which of the following image matrixes will result in the least resolution?

2048x2048
512x512
1089x1089
128x128

Answer to Question 1

the distal fibula superimposed over the posterior half of the tibia

Rationale: Proper lateral positioning of the lateral ankle will demonstrate the distal fibula superimposed over the posterior half of the tibia. An attempt to superimpose the medial and lateral malleolus will cause malrotation of the lateral position.

Answer to Question 2

128x128

Rationale: As a matrix size is increased, an increased number of smaller pixels will fill the matrix increasing resolution. When there are fewer and larger pixels within a matrix, the image quality is poor with less resolution.
