Flail chest d. None of the above 40 Both nuclear medicine and MRI (magnetic resonance imaging) studies can be performed to evaluate metastatic rib lesions before conventional rib radiographic examination. 41 A congenital defect characterized by anterior protrusion of the lower sternum and xiphoid process is termed: 42 Multiple myeloma is seen often in the flat bones of the bony thorax. 43 Which condition of the sternum is often termed “funnel chest?” 44 Both bony and soft tissue anatomy may be evaluated by CT for pathology involving the sternum or the sternoclavicular joints. 45 The condition, flail chest, is most commonly caused by: 46 A radiograph of an RAO sternum reveals that it is partially superimposed over the spine. What must be done to eliminate this problem during the repeat exposure? Increase rotation of the body. 47 A radiograph of a lateral projection of the sternum reveals that the patient’s ribs are superimposed over the sternum. What needs to be done to correct this problem during the repeat exposure? Ensure that the patient is not rotated. 48 A radiograph of an RAO projection of the sternum demonstrates excessive lung markings obscuring the sternum. A 1-second exposure time and an orthostatic (breathing) technique were used. Which of the following will produce a more diagnostic image of the sternum? Increase the exposure time; decrease the mA. 49 A PA radiograph of the sternoclavicular (SC) joints demonstrates unequal distance from the SC joints to the midline of the spine. The left SC joint is farther from the sternum than the right. What specific positioning error is present on this radiograph? Slight right rotation (right side toward the image receptor)
50 A young female patient from the emergency department (ED) is brought to radiology for rib examination. She is able to sit up or stand for the procedure. She indicates that the region of pain is to the right anterior-to-mid axillary region. Which rib projections should be performed to minimize the effective dose to this patient? 51 A patient enters the ED with an injury to the left anterior lower ribs. Which of the following projections should be taken to demonstrate the involved area? 52 An ambulatory patient enters the ED with a possible injury to the right upper posterior ribs. Which of the following routines should be taken to demonstrate the involved area? 53 A patient enters the ED with blunt trauma to the sternum. The patient is in great pain and cannot lie prone on the table or stand erect. Which of the following routines would be best for the sternum examination in this situation? LPO and horizontal beam lateral projections 54 A patient enters the ED with trauma to the bony thorax. The initial radiographs reveal that there are fractured ribs and a possible pneumothorax of the left thorax. The physician orders a chest study to confirm the pneumothorax; however, the patient cannot stand. Which of the following positions would best demonstrate the pneumothorax? 55 Initial PA projections of the SC joints indicate a possible defect involving the left SC joint. The vertebral column is preventing a clear view of it. Which of the following projections will demonstrate the right SC joint without superimposition over the spine? 56 The use of 125 kV is recommended for AP and PA projections of the ribs to reduce skin dose. 57 What is the minimum number of ribs that must be demonstrated for a unilateral rib study above the diaphragm? 58 A lateral projection of the sternum requires that respiration be suspended on expiration. 59 A radiograph of an RAO projection of the ribs demonstrates the left axillary ribs are foreshortened, whereas the right side is elongated. Which of the following is the most likely reason for this radiographic outcome? An LAO was performed rather than the RAO position 60 A patient with metastatic disease in the ribs comes to radiology following a nuclear medicine scan. The radiologist orders a right, upper posterior rib study performed. Which of the following positioning factors should be followed for this specific study? a.Perform positions erect if the patient’s condition permits. c. Include the RPO position as part of the positioning routine. d. Both A and C are correct. 61 Which of the following positioning considerations does NOT apply for a study of the lower ribs? Use a digital kV range between 65 and 70 kV. How much rotation and which oblique position are required to best demonstrate the left sternoclavicular joints?the patient is preferably laid prone with a 10 to 15-degree anterior oblique rotation this is normally achieved with a wedge sponge helping the patient maintain position.
