When instructing the patient for an open mouth waters, the OML forms a 37° angle with the MML perpendicular to IR and CR exiting the acanthion- instruct the patient to correctly to open the mouth you should instruct to say:

“Without moving your head, drop your jaw”

If the patient cannot position for the scaphoid view with ulnar deviation; the alternative would be to

elevate hand 20°, no CR angle -directed at scaphoid

For an AP KUB, CR should be centered at the

Iliac crest

For a lateral decubitus abdomen CR should be placed

2 inches above Iliac crest

For an AP upright abdomen CPR should be centered

2 inches above iliac crest to include the diaphragm; where top of IR is approximately the level of the axilla

For an acute abdominal series why is APA chest included

chest allows free intraperitoneal air under the diaphragm to be visualized

For lateral an AP projections of the upper airway it is best to expose during

During slow deep inspiration to fill the trachea with air

The zygapophyseal joint service visualized on an oblique radiograph of how many degrees

70 Agree oblique positioning to view opposite side (LPO to view right upside zigs joints)

What amount of degree do we angle for SI joint’s

30 to 35° cephalad | 2 inches below ASIS

What is a retrograde sister graffiti exam used for

To examine the bladder

What is a voiding cystourethrography used for

Bladder and urethra

When performing an IV you, the NEFFA Graham picture is taken when

Immediately after contrast is injected continuing images every 5 minutes ending at 20 minutes post injection

The outlet and ramus of the ischium

How do we angle for the Taylor method outlet of the pelvis

Cephalad | 20 to 35° for males 30 to 45° for females

For a standard modified cleans method of the hip a 45° abduction is required to keep the for moral neck parallel what degree of abduction can be used for no for shortening

20 to 30° abduction

Apopaphyseal joints are also called
