About Oesophageal Transit Scan (ROTS)

An Oesophageal Transit Scan is a nuclear medicine imaging examination used to evaluate the movement of swallowed material through the oesophagus, the muscular tube that carries food and liquids from the mouth to the stomach. The study uses a radiotracer and gamma camera imaging to assess oesophageal transit according to the prescribed protocol.

The examination may provide functional information about the passage of a swallowed tracer through the oesophagus. The specific procedure and interpretation depend on the clinical indication and the nuclear medicine team's protocol.

What Does an Oesophageal Transit Scan Evaluate?

The scan evaluates the movement of swallowed material through the oesophagus and may help identify delayed or abnormal oesophageal transit. The findings can provide additional functional information when a swallowing or oesophageal motility disorder is suspected.

Results are interpreted alongside symptoms, medical history and other investigations. The scan does not replace every other test used to evaluate oesophageal structure or function.

Why Is an Oesophageal Transit Scan Recommended?

A doctor may recommend an oesophageal transit study when assessment of swallowing function or oesophageal transit is clinically indicated. It may be considered in selected patients with difficulty swallowing or suspected abnormalities in the movement of material through the oesophagus.

The referring doctor determines whether this examination is appropriate based on the patient's symptoms and previous investigations.

How Is an Oesophageal Transit Scan Performed?

The patient is positioned according to the imaging protocol and asked to swallow a small quantity of material containing a prescribed radiotracer. A gamma camera records images as the tracer moves through the oesophagus.

The nuclear medicine team assesses the recorded images to evaluate oesophageal transit. The exact tracer preparation, swallowing instructions, imaging positions and duration depend on the examination protocol.

Preparation for Oesophageal Transit Scan

Preparation requirements vary depending on the prescribed protocol and the patient's medical condition. Patients should follow the instructions provided by the nuclear medicine team before the appointment.

• Inform the team about swallowing difficulties and relevant medical conditions.
• Bring previous oesophageal investigations and relevant medical reports, if available.
• Inform the team about current medications and any known allergies.
• Tell the team about pregnancy or possible pregnancy and breastfeeding, where applicable.
• Follow any instructions regarding fasting, food or fluid intake before the examination.

Do not stop prescribed medications unless instructed by the treating doctor or nuclear medicine team.

Benefits of Oesophageal Transit Scintigraphy

Oesophageal transit scintigraphy provides functional imaging information about the passage of swallowed material through the oesophagus. It may support the evaluation of suspected transit abnormalities when clinically appropriate.

The results should be considered alongside clinical assessment and other investigations. Additional tests may be needed to assess oesophageal structure, pressure patterns or the cause of swallowing symptoms.

Understanding the Oesophageal Transit Scan Report

The report may describe the observed movement of the radiotracer through the oesophagus and identify findings suggestive of delayed or abnormal transit. Interpretation depends on the imaging protocol and the patient's clinical context.

A qualified nuclear medicine physician interprets the images and provides findings for the referring doctor. The report alone may not establish the underlying cause of swallowing difficulties.

Frequently Asked Questions

What is an Oesophageal Transit Scan?

An Oesophageal Transit Scan is a nuclear medicine study that evaluates the movement of swallowed material through the oesophagus using radiotracer imaging.

Why is an Oesophageal Transit Scan performed?

It may be recommended to assess oesophageal transit when a swallowing or oesophageal motility abnormality is suspected.

Does an Oesophageal Transit Scan use a gamma camera?

Yes. The study uses a gamma camera to record the movement of a swallowed radiotracer through the oesophagus.

Does an Oesophageal Transit Scan involve radiation?

Yes. The examination uses a radioactive tracer and involves exposure to ionising radiation. The nuclear medicine team selects the appropriate protocol for the clinical indication.

Is fasting required before an Oesophageal Transit Scan?

Preparation requirements depend on the imaging protocol. Follow the instructions provided by the nuclear medicine team regarding fasting, food and fluid intake.

How long does an Oesophageal Transit Scan take?

The duration depends on the prescribed protocol and the time needed to record oesophageal transit. Contact the imaging centre for examination-specific timing information.

Can an Oesophageal Transit Scan identify swallowing problems?

The scan can provide functional information about oesophageal transit and may help identify abnormal movement. Further investigations may be required to determine the cause of swallowing difficulties.
