Fluoroscopy final exam
1. Fluroscopy The ability to view and record anatomy in motion (evaluated function and
form)
2. Why fluroscopy -observe gi-tract in motion
- provide inages during the course of the exam
- determine the appropriate course of action
3. Contrast types -barium sulfate
-water soluble
-single contrast
-double contrast
4. Barium sulfate - Positive or radiopaque
- chalk like
- absorbs more X-rays
-BaSO4
-used to view the Gi
-mixed with water
5. Thick barium 3:1 or 4:1 ratio of BaSO4 to water
6. Thin barium 1:1 ratio of BaSO4 to water
7. colloidal suspension Barium never resolved in water
8. Water soluble iodinat- -Used for suspected of perforation or a surgical procedure
ed contrast media -if it escapes the GI tract it can be absorbed by the body unlike barium
sulfate
- bitter taste
- do not use if the patient is allergic to iodine or dehydrated
-Shorter transit time that barium and is more liquid
9.
, Fluoroscopy final exam
Single contrast tech- A single contrast solution alone. These studies rely more heavily on diag-
nique nostic fluoroscopy, mucosal relief and barium filling.
10. Double contrast The use of positive (barium or like agent) and negative contrast (air and
CO2) agents to increase the sensitivity of the exam
11. The reasons to use - detection of polys and colorectal cancer
double contrast - follow up screening
- diverticulitis disease evaluation
-failed colonoscopy
- investigation of non-specific abdominal pain
12. Fluoroscopy exams -esophageal
- Upper Gi
- small bowel follow thru
- lower Gi
13. Esophagram Known as a barium swallow that evaluated the form and function of the
pharynx and eaophagus
14. Esophagram clinical -anatomical anomalies
indications - esophageal reflux
- esophageal varicies
-foreign body obstruction
- impaired swallowing mechanism
- carcinoma of eaophagus
15. Esophagus is posterior Important anatomy
to the trachea and an-
terior to cervical verte-
bra
