primary controlling factor for radiographic contrast in analog imaging
kVp
the palpable landmark for the AP chest projection on bariatric patients
jugular notch
to ensure that the inferior margin of the abdomen is included on a KUB radiograph, the technologist should palpate the:
greater trochanter
a skiers thumb injury is an injury of the:
ulnar collateral ligament
a patient is erect facing the x-ray tube and leaning the shoulders backward 20 to 30 degrees toward the IR. the central ray is perpendicular to the IR.
lordotic
number of x-ray photons that strike the digital receptor
signal
the laryngeal prominence is a positioning landmark located at the level of:
C4-5
the iliac crest corresponds with __ vertebral level
L4-5
how much flexion of the hand is required for the Brewerton method?
65 degrees
a patient comes to radiology for a routine chest study. on the PA projection, the radiologist sees a possible calcification near a rib, but she cannot tell whether the calcification is in th lung or on the rib. what additional projection would assist with the diagnosis?
inspiration/expiration PA
the adjustment of contrast and brightness of the displayed image
bit depth
type of Cr angle required for the AP axial projection for the lung apices
15-20 degrees cephalad
a patient comes to radiology with a clinical history of a possible abdominal aortic aneurysm. which of the following abdominal projections would best demonstrate this condition
dorsal decubitus
how much CR angulation to the long axis of the hand is required for the tangential, inferosuperior projection to demonstrate the carpal sulcus
35 to 45 degrees
what position will best demonstrate the pre vertebral region?
lateral abdomen position
a patient is lying on her back. the x-ray tube is horizontally directed with the CR entering the right side of the body. the image receptor is adjacent to the left side of the body. what is the radiographic position?
dorsal decubitus
a patient enters the ED with a possible pneumothorax in the left lung. because of trauma, the patient cannot stand or sit erect. which of the following positions would best demonstrate this condition?
right lateral decubitus
a radiograph of a AP abdomen demonstrates elongation of the left iliac wing and narrowing of the right iliac wing. which one of the following positioning errors produced this radiographic outcome?
rotation to the left (LPO)
which special projection of the wrist is ideal for demonstrating possible calcification in the dorsal aspect of the carpals
carpal bridge
a radiograph of the PA scaphoid projection reveals extensive superimposition of the scaphoid and adjacent carpals, which of the following factors can lead to this problem?
elevation of the hand and wrist
a patient is erect with the left side of his chest placed against the image receptor. the cr enters the right side of the upper chest and exits the left. which specific position has been performed?
transthoracic lateral
a patient is in the icu with multiple injuries. the physician is concerned about a pleural effusion in the left lung. the patient cannot stand or sit erect due to age. which projection should you use?
left lateral decubitus
what can produce a dynamic bowel obstruction?
fibrous adhesions, Crohn's disease, intussusception
which projection best demonstrates the radial head using the trauma lateral Coyle method routine
Elbow flexed 90 degrees, Cr angled 45 degrees toward shoulder
the patients head and neck are hyperextended with the top of the skull directly against the ir. the cr enters just below the chin. which specific projection has been performed?
submentovertical
