The proper name of the method used for the unilateral frog-leg projection is the _____ method.

What CR angle is required for the AP axial, inlet projection?

A radiograph of an AP pelvis reveals that the lesser trochanters are not visualized. This pelvis projection was performed for nontraumatic reasons. What should the technologist do (if anything) to correct this on the repeat exposure?

A radiograph of an AP pelvis reveals that the right iliac wing is foreshortened as compared with the left side. What specific positioning problem is present on this radiograph?

A radiograph of an AP pelvis reveals that the left obturator foramen is more open or elongated as compared with the right. What is the specific positioning error present on this radiograph?

A radiograph of a unilateral frog-leg (modified Cleaves method) projection reveals that the femoral neck is foreshortened and distorted. The radiologist is concerned about pathology involving the neck. What can the technologist do to improve the visibility of the femoral neck without foreshortening during the repeat exposure?

A radiograph of an axiolateral (inferosuperior) projection of the hip reveals a soft tissue artifact seen across the affected hip. This artifact prevents a clear view of the femoral head and neck. What must the technologist do to eliminate this artifact or its effect during the repeat exposure?

A PA axial oblique projection (Teufel method) is performed on a patient. The resultant radiograph demonstrates distortion of the acetabulum. The following positioning factors were used: 40° anterior oblique, 12° cephalad CR angle, and CR centered to the upside hip (acetabulum). What needs to be modified during the repeat exposure?

A radiograph of an axiolateral (inferosuperior) projection reveals that there is an excessive amount of grid lines present. A 6:1 linear grid was used. Which of the following points will correct this problem on the repeat exposure?

A patient enters the ER having sustained trauma to the pelvis. The patient’s main complaint is about her left hip. Which of the following projections should be taken first to rule out fracture or dislocation?

A nontrauma patient comes to radiology with a history of chronic pain of the right hip. The patient is ambulatory but has not had previous radiographs taken of that hip. Which of the following routines would be best suited for this patient?

Generally, gonadal shielding for females cannot be used for an initial AP pelvis for pelvic trauma due to the possibility of covering pertinent anatomy.

Less abduction of femora of only 20

If a patient has excessive external rotation of one foot, a fractured hip may be indicated.

A radiograph of an AP axial (Taylor) “outlet” projection reveals that the obturator foramina are not symmetric. What type of positioning problem is present on this radiograph?

During a repeat study of the AP axial (Taylor) outlet projection, both obturator foramina are symmetric but foreshortened. Which of the following positioning modifications must be performed to correct this error?

A patient enters the ER with a possible separation of the symphysis pubis caused by trauma. The AP pelvis projection is inconclusive for determining the extent of the injury. What other projection can be taken to evaluate this region without excessive movement of the patient?

A patient comes to radiology with a request for a right hip study. He is from an extended care facility and is confusedabout the cause of the injury. The technologist takes an AP pelvis, and when the lateral frog-leg projection is attempted, the patient complains loudly about the pain in his affected hip. What should the technologist do to complete the study?

A patient enters the ER with possible bilateral fractured hips. Which of the following routines should be performed?

A patient comes to the ER with a possible pelvic ring fracture. The initial AP pelvis projection is inconclusive. What other projection can be taken to assist with the diagnosis?

A radiograph of an AP pelvis demonstrates that the right obturator foramen is foreshortened but the left foramen is open. Which one of the following positioning errors is present on this radiograph?

A patient enters the ER with a possible pelvic ring fracture due to a MVA. The initial pelvis projections do not reveal any fracture or dislocation, but the ER physician is concerned about a possible right acetabular fracture. Which of the following projections will best demonstrate the right acetabulum?

Which of the following lateral hip projections cannot be performed on a trauma patient with a possible hip fracture?
