Technical Factors and errors
100

This abdominal projection is often selected to best demonstrate the presence of an Abdominal Aortic Aneurysm

Dorsal Decub

100

This medical term is the formal diagnosis for a bowel obstruction

Ileus

100

The necessary Central Ray (CR) angulation for an AP axial clavicle projection on a hypersthenic patient typically falls within this 5-degree range

15-20

100

When performing an acute abdomen series, this lateral decubitus position is preferred because it places the liver margin superiorly, allowing free air to be visualized beneath it

Left lateral Decub

100

To eliminate motion blur caused by involuntary contractions such as bowel peristalsis during a repeat abdominal exposure, the radiographer should decrease this factor

mAs

200

The chief disadvantage of performing an AP chest projection compared to a PA projection is the resulting increased magnification of this vital organ  

Heart

200

 A local or generalized infection of the bone or bone marrow, typically caused by bacteria introduced via trauma or surgery

osteomyelitis

200

 The CR angulation required for the AP oblique projection of the foot

15-20 posteriorly

200

This positioning requirement is the most crucial factor for demonstrating potential air and fluid levels within the chest

 having the patient in an erect or decubitus position

200

 If an AP pelvis radiograph shows the right iliac wing is foreshortened compared to the left, this specific rotational positioning error has been committed

left rotation

300

To ensure the diaphragm is visible on an AP erect abdomen image, the top of the image receptor should be positioned near this anatomical landmark

Axilla

300

 This is the term for the internal ridge or prominence where the trachea divides into the right and left bronchi

Carina

300

The required CR angulation to the long axis of the foot for a plantodorsal (axial) projection of the calcaneus (degree and direction)

40 cephalic

300

If a PA and a lateral projection of the chest are inconclusive in demonstrating a possible mass beneath the right clavicle, this projection is often added to the routine

AP lordotic

300

If an AP pelvis radiograph reveals that the left obturator foramen is more open or elongated compared to the right, this rotational error has occurred

right rotation

400

To properly visualize air-fluid levels on an AP erect abdomen projection, the patient must maintain this position for a minimum of five minutes before the exposure

Upright

400

The dense fibrous membrane that acts as a protective covering for bone.

periosteum

400

In an AP external rotation projection of the shoulder, the humeral epicondyles must maintain this specific relationship relative to the image receptor (IR)

Parallel

400

This oblique ankle projection is specifically designed to open the joint space of the medial and lateral aspects of the tibiotalar joint

AP mortise projection

400

 This excessive rotation of the forearm is the positioning error that causes the complete separation between the proximal radius and the ulna on an AP elbow projection

excessive lateral rotation

500

To reduce the magnification of the heart on an AP supine chest performed in the Emergency Department (ED), the technologist should increase what as much as possible

SID

500

These three bones—the ilium, ischium, and pubis—ultimately fuse together to form this deep, cup-shaped structure of the pelvis

Acetabulum

500

Rotating the lower limb 15° to 20° internally for an AP hip projection serves this crucial purpose, ensuring accurate visualization of a key anatomical structure

femoral neck parallel to the image receptor

500

In the Emergency Room (ER) for a patient with possible bilateral fractured hips, the recommended radiographic routine is an AP pelvis plus what projection?

modified axiolateral (Clements-Nakayama method)

500

This respiratory phase should be employed during the exposure for the anteroposterior (AP) kidneys, ureter, and bladder (KUB) abdomen projection
