Question 1

&#10;&#10;-Refer to the figure. Name the radiographic view.&#10;A) Anteroposterior&#10;B) Lateral&#10;C) Anteroposterior obliques (mortise)

Accepted Answer

Anteroposterior&#10;

Question 2

&#10;&#10;-Refer to the figure. On this standard view, which of the following is not well visualized?&#10;A) Distal tibia&#10;B) Distal fibula&#10;C) Subtalar joint&#10;D) Talar dome

Accepted Answer

The subtalar joint is not well visualized on a standard ankle X-ray, which typically focuses on the distal tibia, distal fibula, and talar dome.

Question 3

&#10;&#10;-Refer to the figure. Name the radiographic view.&#10;A) Anteroposterior&#10;B) Lateral&#10;C) Anteroposterior obliques (mortise)

Accepted Answer

The radiographic view shown is the anteroposterior oblique (mortise) view, which is used to visualize the ankle joint with the foot internally rotated to show the mortise joint space clearly.

Question 4

&#10;&#10;-Refer to the figure. This view allows for optimal assessment of the:&#10;A) Talar dome&#10;B) Subtalar joint&#10;C) Lateral malleoli&#10;D) Midtarsal joint

Accepted Answer

The talar dome is best assessed in a specific view that allows for clear visualization of the talus bone, which is typically the focus of such assessments.

Question 5

&#10;&#10;-What is the ankle mortise?&#10;A) Radiographic joint space of the ankle&#10;B) Tibiofibular joint space&#10;C) Subtalar joint space&#10;D) Midtarsal joint space

Accepted Answer

The ankle mortise refers to the radiographic joint space of the ankle, which is formed by the tibia, fibula, and talus.

Question 6

&#10;&#10;-Which radiograph view of the foot provides for the optimal evaluation of first metatarsophalangeal alignment related to hallux valgus deformity?&#10;A) Anteroposterior&#10;B) Lateral&#10;C) Oblique

Accepted Answer

The anteroposterior (AP) view is optimal for evaluating the alignment of the first metatarsophalangeal joint, which is crucial for assessing hallux valgus deformity. This view allows for the best visualization of the angular relationships between the bones.

Question 7

&#10;&#10;-Which radiograph view of the foot provides for the most visualization of the base of the fifth metatarsal?&#10;A) Anteroposterior&#10;B) Lateral&#10;C) Oblique

Accepted Answer

The oblique view of the foot is specifically tailored to provide the best visualization of the base of the fifth metatarsal, among other structures. This angle allows for a clearer view of the bone's structure and any potential injuries, such as fractures, which might not be as visible in anteroposterior or lateral views.

Question 8

&#10;&#10;-Tenderness to palpation in what area of the foot warrants getting radiographs, according to the Ottawa Foot and Ankle Rules, in an individual who describes an inversion ankle sprain?&#10;A) Calcaneus&#10;B) Cuboid groove&#10;C) Base of fifth metatarsal&#10;D) Head of fifth metatarsal

Accepted Answer

The Ottawa Foot and Ankle Rules suggest that radiographs are necessary if there is pain in the malleolar or midfoot area and one of the following: bone tenderness at the base of the fifth metatarsal (among other specific points), inability to bear weight both immediately and in the emergency department for four steps. This is to rule out fractures that might be missed on physical examination alone.

Question 9

&#10;&#10;-Refer to the figure. Identify the image.&#10;A) Sagittal T1-weighted MRI&#10;B) Sagittal T2-weighted MRI&#10;C) Coronal T1-weighted MRI&#10;D) Coronal T2-weighted MRI

Accepted Answer

The image is a Sagittal T2-weighted MRI because the cerebrospinal fluid (CSF) appears bright, which is characteristic of T2-weighted images, and the view is sagittal as it shows a side view of the spine and brain.

Question 10

&#10;&#10;-Refer to the figure. You correctly identified the sequence in question 9 because joint fluid is seen as:&#10;A) A high-intensity signal in this sequence&#10;B) A low-intensity signal in this sequence

Accepted Answer

Joint fluid appears as a high-intensity signal (bright) on T2-weighted MRI sequences, which is likely the context of this question.
