A

Open-mouth Waters

21
Q

Axiolateral oblique mandible: the central ray is directed how many degrees and in what direction?

Which portions of the mandible are demonstrated at the 4 different possible levels of obliquity?

A

25 degrees cephalad (entering the body of the upside mandible, downside is of interest)

Head in true lateral: ramus
10-15 degree toward IR: general survey
30 degrees toward IR: body
45 degrees: mentum

22
Q

A

lateral
Caldwell
Waters and Modified Waters

24
Q

What quantity of radiation exposure to the reproductive organs is required to cause temporary infertility?

25
Q

Rubeola requires ____ precautions

A

Airborne (particles stay suspended up to 2 hours)

26
Q

What is VRE and what type of precautions does it require?

A

Vancomycin resistant enterococci, contact precautions

27
Q

Adenovirus is a common cause of _____ illness and requires _____ precautions

A

Respiratory; contact

28
Q

An AP of the right ilium requires the patient’s ____ side to be elevated ____ degrees

A

Left, 40

29
Q

In a posterior oblique pelvis (Judet method), placing the affected side down will demonstrate the _____ acetabular rim and the posterior ______ column

A

Anterior, ilioischial

30
Q

Hemovac or Penrose drains are usually used for…

A

Tissue drainage of wounds or postoperative drainage

31
Q

For the Judet method, thr affected side is normally imaged as both the upside and down side. So for the right acetabulum, you would do what 2 45 degree oblique positions? What would be the CR in each case?

A

One RPO and one LPO

For the right acetabulum, the LPO focuses on the upside, CR 2 inches distal to upside ASIS.

For the RPO, focused on the downside acetabulum, CR is 2 inches distal AND medial to the downside ASIS

32
Q

For the Judet method for the right acetabulum, the LPO will show what 2 key pieces of anatomy on the upside acetabulum?

The RPO should show what 2 key pieces of anatomy on the downside?

A

LPO: upside posterior rim of acetabulum and anterior iliopubic column

RPO, downside anterior rim of acetabulum and posterior ilioischial column

33
Q

Images obtained using DXA (dual x-ray absorptiometry) bone densitometry… (choose which apply)

  1. Are used to evaluate the accuracy of the region of interest (ROI)
  2. Are used as evaluation for various bone/joint disorders
  3. Reflect the similar attenuation properties of soft tissue and bone
A

1 only

The images only evaluate that the ROI is accurate; they are not diagnostic

34
Q

DXA is the most widely used method of…

And is used to evaluate…

A

Bone densitometry

BMD (bone mineral density)

35
Q

For atelectasis, technique should be…

A

Increased

A

$50,000 and up to 1 year in prison

39
Q

Barium filled structures are often imaged using ___ kVp or more to ____

Female: 80 to 85 degrees

41
Q

What’s the difference between the male and female acetabulum?

A

Nonlinear threshold

A

Radial neck
Fractures of the radial head

44
Q
