Dynamic Oesophageal Images
Lt Lateral - using x3 types of different solids
Oesophageal Study
Procedure:
-
You have been referred for an Oesophageal Study in which imaging is done whilst sitting infront of a Gamma Camera (1).
-
An Oesophageal Study is very sensitive in showing how well the oesophagus transports food to the stomach.
-
The study is useful in identifying the presence of motility disorders including: achalasia, scleroderma, and diffuse esophageal spasm.
-
The test involves swallowing water and certain foods that have been labelled with a small amount of radioactive tracer.
-
The tracer we use is called 99mTc-DTPA (99m-Technetium diethylene-triamine-penta-acetic acid).
-
There are rarely any side effects with ingesting the tracer and there is no taste to the tracer.
-
The images are done sitting and with your left-side towards the camera.
-
These images are done in two phases - the "Liquid phase" and the "Solid phase". It takes approximately 1 hour to complete the study.
-
Your results usually take 2 hours to produce, hence we usually send these directly to the referring doctor.
-
You receive a slight radiation dose by having an Oesophageal Study ~ up to 0.7 times your yearly background radiation (2).
Patient Preparation:
-
If you are pregnant, trying to fall pregnant or breast feeding, you must inform our staff.
-
You must NOT eat or drink anything for at least 4 hours prior the test.
-
Refrain from smoking on the day of the test.
-
If you have had prior imaging e.g. PET, Nuclear Scan, CT, MRI, X-Ray, Ultrasound, etc... please bring these with you.
-
Please also bring your referral and any blood results that you may have had done.
-
If you are on any medications, please take these as normal.
-
Wear comfortable clothing and minimise the amount of metal jewellery you have on (all metal objects will need to be removed prior to imaging).
-
Important Note: You cannot have this test if you have had a PET or Nuclear Scan within 24 hours prior to this test. If you have had Iodine-131 therapy, allow 4-weeks before having this test. Please ring to discuss booking options.
Breast-Feeding Mothers: Once you have been given the tracer, you need to stop breast-feeding for two feeds. During this time, you need to express and discard your breast milk. You will need to bottle-feed your child during this period.
(1) A Gamma Camera is a device that detects gamma-rays (gamma-rays are very similar to x-rays) and does not emit any radiation.
(2) We all receive a yearly background radiation dose ~ 2.4mSv. Oesophageal Study ~ 1.7mSv = 0.7 times yearly background dose.
