2. BARIUM SWALLOW
• It is a Medical Imaging Procedure used to examine the
Upper
• Gastro intestinal Tract, which include the Oesophagus and to
• Lesser extent the Stomach.
The Contrast used is Barium Sulphate.
3. Anatomy
The Oesophagus begins at the upper Oesophageal sphincter at
the level of C6 and ends at lower Oesophageal sphincter at
thoracic eleven and is approx. 25 cm in length.
4. Constrictions
• Superiorly : Level of Cricoid Cartilage, Junction with
Pharynx
• Middle : Crossed by Aorta and left main Bronchi
• Inferiorly : Diaphragmatic Sphincter
7. SPHINCTERS
• Two high pressure zones prevent the backflow of food
• Upper Esophageal Sphincter
• Lower Esophageal Sphincter
• It is located at the upper and lower end of Oesophagus.
18. PATIENT PREPARATION
• NPO prior to the procedure.
• Ensure that no contra indication to the contrast agent.
• Check pregnancy status for female of child bearing age.
• Procedure should be explained to the patient before under
• Going the procedure and the duration the exam may take.
• Any other medical history needed.
19. Radiographic Views
• VIEWS OR PROJECTIONS
• A.P Scout
• Lateral
• Right Anterior Oblique (RAO)
• Soft Tissue Neck – A.P & LAT
• Neck – AP & Lateral
• Thorax –( RAO)
25. Critique criteria:
Right Anterior Oblique, Lateral Oblique's
The RAO should demonstrate the entire barium filled
Esophagus.
Like the RAO stomach , which is the single best projection, the
Right anterior oblique is also best for the esophagus.
The heart provides a homogeneous back ground to contrast it
Against and the distal esophagus traversing the esophageal
Hiatus is laid out in profile.
