Exam 6: Lower Limb

The superoinferior,tangential (Hobbs modification)projection requires a CR angle of 5° to 10° posterior.

A radiographic appearance of a highly malignant and extensively destructive lesion that usually occurs in long bones and produces a sunburst pattern describes:

To ensure that both joints are included on an AP projection of the tibia and fibula on an adult,the technologist should:

How much is the foot dorsiflexed with the tangential projection for the sesamoid bones if the CR remains perpendicular to the image receptor?

Which projection of the knee will best demonstrate the neck of the fibula without superimposition?

A patient enters the ED with an injury near the base of the first and second metatarsals.The basic foot projections are inconclusive on demonstrating a fracture to the medial cuneiform.Which of the following projections would best demonstrate this bone?

MATCHING Match the correct disease or condition with the corresponding pathologic description.(Use each choice only once.) -Condition affecting the sacroiliac joints and lower limbs of young men,especially the posterosuperior margin of calcaneus

The patella is drawn into the intercondylar sulcus when the knee is overextended.

A patient enters radiology with a possible ligament tear to the lateral aspect of the ankle.Initial ankle radiographs are negative for fracture or dislocation.Because the clinic is in a rural setting,the patient cannot have an MRI performed to evaluate the ligaments of the ankle.Which of the following techniques may provide an assessment of the soft tissue structures of the ankle?

Which structure or bone contains the sustentaculum tali?

A geriatric patient comes to the radiology department for a study of the knee.The patient is unsteady and unsure of himself.Which intercondylar fossa projection would provide the best results without risk of injury to the patient?

MATCHING Match the correct disease or condition with the corresponding pathologic description.(Use each choice only once.) -Benign,neoplastic bone lesion filled with clear fluid

A correctly positioned AP 45° medial oblique ankle projection frequently may also demonstrate a fracture of the base of the fifth metatarsal if present.

The distal tibiofibular joint is classified as a ____ joint.

Which special position of the knee requires that the patient be placed supine with 40° flexion of knee with the CR angled 30° from the long axis of the femur?

Which of the following projections of the patella requires the patient to be placed in a prone position,a 55° flexion of the knee,and a 15° to 20° angle of the CR?

A patient comes to the radiology department for a knee study with special interest in the region of the proximal tibiofibular joint and the lateral condyle of the tibia.Which of the following positioning routines should the technologist obtain?

For the AP weight-bearing feet projection,the CR should be:

To decrease the angle between the anterior surface of the foot and anterior surface of the lower leg is described as:

MATCHING Match the correct disease or condition with the corresponding pathologic description.(Use each choice only once.) -An inflammatory condition involving the anterior,proximal tibia
