Q

Why do you need to mix foods with barium during an MBS?

A

Barium is radiopaque and appears black on an image making it easier to see and track.

Q

 Indications for an Instrumental Examination (Text: Box 10-2)

A

◦ Examination Definitely Indicated:
 Characteristics vague
 Nutritional or respiratory issues
 Safety of efficiency a concern

◦ Examination May Be Indicated
 Medial condition high risk for dysphagia
 Swallow changes
 Unable to cooperate with clinical exam

◦ Examination NOT indicated
 No complaints
 Too medically fragile or uncooperative
 MBS will not change course of treatment

Q

 Videofluoroscopic Examinations

◦ What’s in a Name?

A

 Modified Barium Swallow (MBS)
 Upper Gastrointestinal Series with hypopharynx
 Videofluoroscopic Swallow study (VFSS)
 Videofluoroscopic barium examination (VFBE)
 Videofluoroscopic swallow examination (VFSE)
 Rehabilitation swallow study
 Video-esophagram (early Logemann!)
 Dysphagiagram (Okie term!)

17
Q

 Principles of VFSS

A

◦ X-ray tube moves up and down
◦ X-ray projected in straight lines through the patient to the fluoroscope on the opposite side
◦ Differences in tissue absorption produces varying intensity (darkness)
◦ Radiation dose rate falls when thin body parts are examined and rises with the examination of thick parts

18
Q

 Sequence of materials-
(As recommended in text)
◦ Lateral View:

A

 Speech sample and vowel phonation (to find VFs in MBS, evaluate vocal quality)
 5 ml thick liquid barium
 5 ml barium paste (with pudding)
 10 ml thin liquid barium
 10 ml thick liquid barium
 10 ml barium paste (pudding)
 Thick liquid taken from a cup or through a straw
 Cracker coated with barium paste
 Repeat thin liquid if residue from cracker is still there

19
Q

 Materials & Sequence

A

◦ Anterior View: Repeat vowel phonation and falsetto
◦ Swallow with head forward and turned
◦ Compensatory techniques:
 May try at any time in the examination
◦ Esophageal evaluation
 Quick view for obstruction or dysmotility
 Some Radiologists require this view

20
Q

 Observations to Obtain

See Box 10-6, page 201

A
◦	Anatomy
◦	Non-Swallow movement
◦	Swallow movement
◦	Consequences of impaired swallow
◦	Impact of compensatory maneuvers
21
Q

 Basic Procedures

A
◦	I.  Lateral view:
	Study structures
	Food consistencies
	Liquid- graded thicknesses
	Barium Paste-pudding
	Cookie – solid
◦	II.   A-P view:
	Structures
	Liquid Barium – graded thicknesses
22
Q

 Warning!!! Safety Issues

A
◦	Radiation risks:
	Severe tissue damage
	Cancer
	Genetic Injury
	Fetal Exposure-
	1 1/2 – 2x more sensitive
	Greatest during first 10 days in utero
◦	Areas of greatest risk to exposure:
	Thyroid, lungs, breasts, active bone marrow, ovaries & testes
23
Q

 Safety Issues

See Kelchner, 2004

A
◦	Radiation Protection:
Time- minimize exposure time- less than 2 minutes
Shielding-
	Lead lined apron
	Lead lined gloves
	Lead lined thyroid shield
	Lead lined glasses
Distance
	Scatter- principle hazard to operator
	Inverse square law: if distance is doubled, exposure cut in half
Equipment & Dosimetry
	Wear a dosimeter badge
	Keep levels below 0.01-10 cGy (centiGrays)
24
Q

 Radiation Basics

A

◦ Radiation absorbed dose (rads) measured in Grays
◦ 1 Gray (Gy)= 100 rads
◦ Most work in centiGrays
o 1cGy= 1/100 Gy and 1 rad
o Level normally encountered in Dx radiology =
• 0.01-10 cGy
o Radiation Workers < 0.5 cGy per month

25
Q

 Reliability of VFSS

A

( Stoekli, 2004)
◦ Interrater reliability was poor (kappa coefficient= 0.01-0.56 )
◦ Aspiration the only finding with high interrater agreement
◦ Suggests the need for programs like the MBS-Imp

26
Q

 Endoscopic Examinations

Observations (See Box 10-8)

A

◦ Velopharynx
◦ Pharynx
◦ Larynx
◦ Swallow

27
Q

 Procedures

A
  1. Pass the scope into the nose and down the throat
  2. Observe throat before and after the swallow
    ***During swallow the camera will be white
  3. Swallowing of small amounts of dyed food
  4. Assess:
    o Soft palate
    o Back of tongue movement
    o Larynx
    ◦ 5. Success of compensatory techniques
