Question 1

Multiple myeloma is seen often in the flat bones of the bony thorax.

Accepted Answer

Yes, multiple myeloma is commonly seen in flat bones of the bony thorax, such as the sternum and ribs, as well as in the vertebrae and pelvis.

Question 2

Which condition of the sternum is often termed "funnel chest?"

Accepted Answer

The condition of the sternum often termed "funnel chest" is pectus excavatum, which is characterized by a sunken appearance of the chest.

Question 3

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?

Accepted Answer

The answer of A patient enters the ED with an...

Question 4

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?

Accepted Answer

If the ribs are superimposed over the sternum, it indicates that the patient was rotated during the initial exposure. To correct this problem, the patient should be repositioned to ensure that they are not rotated. Increasing the SID, angling the CR, or increasing the kV will not necessarily improve the superimposition of the ribs over the sternum.

Question 5

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?

Accepted Answer

The answer of A PA radiograph of the sternoclavicular (SC)joints...

Question 6

Which of the following conditions,if severe,requires a decrease adjustment of manual exposure factors?

Accepted Answer

The answer of Which of the following conditions,if severe,requires a...

Question 7

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?

Accepted Answer

Increasing the rotation of the body will move the sternum away from the spine, reducing superimposition.

Question 8

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?

Accepted Answer

The answer of A radiograph of an RAO projection of...

Question 9

The condition,flail chest,is most commonly caused by:

Accepted Answer

Flail chest is most commonly caused by blunt trauma, such as from a car accident or a fall, which results in multiple rib fractures.

Question 10

Both bony and soft tissue anatomy may be evaluated by CT for pathology involving the sternum or the sternoclavicular joints.

Accepted Answer

CT scans can provide detailed images of both bony structures and soft tissues, allowing for evaluation of a variety of pathology involving the sternum and sternoclavicular joints.

Question 11

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?

Accepted Answer

The answer of A young female patient from the emergency...

Question 12

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?

Accepted Answer

The answer of A patient enters the ED with trauma...

Question 13

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?

Accepted Answer

The RAO projection will demonstrate the right SC joint without superimposition over the spine. The right SC joint will be closer to the image receptor and the vertebral column will be posterior to it, resulting in less superimposition. The other projections would not help in demonstrating the right SC joint without superimposition over the spine.

Question 14

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?

Accepted Answer

An erect AP and RPO position is preferred to demonstrate the right upper posterior ribs. The AP view is taken to evaluate the anterior chest and the RPO position allows for better visualization of the right posterior ribs. The LAO position is used to visualize the left posterior ribs, and the recumbent position may not adequately demonstrate the involved area.

Question 15

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?

Accepted Answer

The LPO position allows for visualization of the sternum over the heart shadow, reducing superimposition, and the horizontal beam lateral projection accommodates the patient's inability to stand or lie prone.

Question 16

Fracture of adjacent ribs in two or more places with associated pulmonary injury is known as a(n)_____ rib fracture.

Accepted Answer

A flail chest occurs when two or more adjacent ribs are fractured in two or more places, causing a segment of the chest wall to become unstable and move paradoxically with respiration. This type of injury can cause significant pulmonary injury and compromise breathing.

Question 17

A congenital defect characterized by anterior protrusion of the lower sternum and xiphoid process is termed:

Accepted Answer

The description of anterior protrusion of the lower sternum and xiphoid process is consistent with pectus carinatum. Pectus excavatum is a congenital defect characterized by posterior depression of the sternum (also known as funnel chest), flail chest is a traumatic injury to the chest wall, and sternal protrusion is not a recognized medical term.

Question 18

The radiographic appearance of the erosion of bony rib margins is a possible indication of:

Accepted Answer

The answer of The radiographic appearance of the erosion of...

Question 19

Which disease or condition may be associated with postoperative complications of open heart surgery?

Accepted Answer

The answer of Which disease or condition may be associated...

Question 20

Both nuclear medicine and MRI (magnetic resonance imaging)studies can be performed to evaluate metastatic rib lesions before conventional rib radiographic examination.

Accepted Answer

The answer of Both nuclear medicine and MRI (magnetic resonance...
