Chapter 2 problem solving for technical and positioning Airs

A young child enters the emergency room with a possible foreign body in one of the bronchi of the lung. the foreign body a peanut cannot be seen on the PA and lateral projection of the chest projection which additional projections could the technologist perform to locate the foreign body

AP and lateral upper airway projections

A routine chest series indicates a possible Mass beneath patients right clavicle. The PA and lateral projections are in conclusive. What additional projections could be taken to rule out this condition

AP lordotic

A patient with a possible neoplasm in the right lung apex come to the radiology department for a chest examination. The PA and lateral projection do not clearly demonstrate the neoplasm because of super imposition of the clavicle over the apex. The patient is unable to stand or sit erect. Which additional projection can be taken to demonstrate the neoplasm clearly and to eliminate the super imposition of the clavicle and left lung apex?

AP semiaxle projection CR is angled 15 to 20° and Cephalad to project the clavicles above the APices and to demonstrate clearly the possible tumor

PA and left lateral projection demonstrate a suspicious region in the left lung. The radiologist orders in oblique projection that will best demonstrate or elongate the left lung. Which specific oblique projections will best elongate the left lung? More than one oblique projection will accomplish this goal

Both the LPO and REO oblique positions will best demonstrate or elongate the left lung

A radiograph of APA projection of the chest shows the top of the Apices is cut off in wind collimation border can be seen below the diaphragm in what way I can miss the corrected during the repeat radiographs

Center the central ray higher to the level of T7 which will be found 7 to 8 inches below the vertebra prominens make sure the image receptor is centered to the central ray and the top collimation light border is at the vertebra prominens

A patient with the clinical history of advanced emphysema comes to the radiology department for a chest x-ray. AEC will not be used. How should the technologist all through the manual exposure setting for this patient

Decrease the KV moderately (-,-)

A radiograph of the lateral projection of the chest shows the posterior ribs and Castrophrenic Angles are separated more than 1/2 inch or 1 cm indicating the excessive rotation describe a possible method for determining the direction of rotation

Determine which (right or left )hemidiaphragam ismore posterior or more interior the left can frequently be identified by visualization of the gastric air bubble or the inferior heart shadow both of which are associated with the left hemidiaphragam

A patient with a history of pleurisy comes to the radiology department which of the following radiographic series should be performed.

Erect PA and lateral

A patient with severe Pleural if using comes to the radiology department for a chest x-ray automatic exposure control AEC will not be's house should the technologist alter the manual exposure settings for this patient

Increase the kV slighty (+)

A patient has a possible small pneumothorax routine chest projections (Pa and lateral) fail to show the pneumothorax conclusively. Which additional projections could be taken to rule out this condition

Inspiration and expiration PA projection and or a lateral decubitus AP chest with affected side up

A patient comes to the radiology department for a pre-surgical chest examination the clinical history indicates a possible Situs inverses of the thorax (transposition of structures within thorax )which positioning separate action must be taken to perform a successful's chest examination

Insure the placement of the correct right or left in atomic side marker on The image receptor because the heart and other thoracic structures maybe transpose from the right to left

A patient enters the emergency room with a possible hemothorax in the right lung caused by a motor vehicle accident MVA the patient is unable to stand or sit erect which specific projection would best Demonstrate this this condition in one

Right lateral decubitus in a patient with hemothorax fluid this side of interest should be down

A radiograph of a PA view of the chest shows that the sternoclavicular joints are not the same distance from the spine. The right SC joint is closer to the midline than is the left SC joint. What is the positioning error?

Rotation. The patient is rotated into a slight RAO position

A radiograph of PA projection of the chest shows only seven posterior ribs above the diaphragm what caused this problem and how could it be prevented on the repeat exposures

The lungs are under inflated explain to the patient the need for a deep inspiration and take the exposure on the second deep inspiration
