Lower Extremities RTBC Questions and
Answers Latest Version Already Passed
What is the purpose of radiographic imaging in the lower extremities?
✔✔Radiographic imaging in the lower extremities helps to diagnose fractures, joint dislocations,
bone diseases, and other pathologies related to the hips, pelvis, legs, and feet.
What are the standard views for imaging the hip joint?
✔✔The standard views for imaging the hip joint are the anteroposterior (AP) and lateral views.
What is the best position to visualize the patella in a radiograph?
✔✔The best position to visualize the patella is the lateral view, where the knee is flexed at about
30 degrees.
How is the AP view of the femur performed?
✔✔For the AP view of the femur, the patient lies on their back with the leg extended and the
foot rotated internally to align the femoral shaft.
What should be assessed when evaluating a radiograph of the ankle joint?
1
,✔✔When evaluating a radiograph of the ankle joint, the alignment of the tibia and fibula, the
integrity of the ankle mortise, and the presence of fractures should be assessed.
What is the primary focus of a radiograph of the knee?
✔✔The primary focus of a radiograph of the knee is to assess for fractures, joint space
narrowing, and any abnormalities in the femur, tibia, fibula, and patella.
How is the lateral view of the lower leg achieved in radiology?
✔✔The lateral view of the lower leg is achieved by positioning the patient with the knee slightly
flexed and the foot dorsiflexed, with the tibia and fibula aligned.
What is the significance of the lateral view in imaging the pelvis?
✔✔The lateral view of the pelvis is important to assess the alignment of the hip joint, detect
fractures, and evaluate the relationship between the femoral heads and the acetabulum.
What is the proper positioning technique for a radiograph of the foot?
✔✔For a radiograph of the foot, the patient should be positioned with the plantar surface of the
foot flat on the imaging table, and the foot dorsiflexed for better visualization.
2
, How is the AP view of the tibia and fibula performed?
✔✔For the AP view of the tibia and fibula, the patient should be supine with the leg extended,
and the foot dorsiflexed so the toes point upward.
What does the term "mortise" refer to in ankle imaging?
✔✔The term "mortise" refers to the space between the tibia, fibula, and talus that forms the
ankle joint. It is assessed to check for fractures or misalignment.
What is the importance of obtaining weight-bearing views for the lower extremities?
✔✔Weight-bearing views are important for assessing joint space narrowing, osteoarthritis, and
the alignment of bones under the patient's natural weight load.
How does the oblique view of the foot help in diagnosis?
✔✔The oblique view of the foot is useful for evaluating fractures, dislocations, and deformities,
particularly in the metatarsals and phalanges.
What is the purpose of the frog-leg view in pelvic radiography?
✔✔The frog-leg view is used to evaluate the hip joints for dislocations, fractures, and arthritis by
positioning the patient with their knees bent and feet together.
