What is a LD CT Chest scan?

A HR CT Chest scan uses High Resolution CT Technology  to examine the chest, including lungs and heart. Thin slice images  are taken to provide extremely high definition images of lung alveoli, airways, interstitium, and pulmonary vessels.

What happens during a HR CT Chest scan?

A. Before your scan

What to bring

  • Your request form
  • Any relevant previous imaging
  • Your Medicare card and any concession cards

Preparation – On the day of the scan

You will be asked to fill out a questionnaire regarding your health status, medication, and any known allergies. If there is any chance you may be pregnant, please inform us before your scan. You may also be asked to change into a gown and remove some jewellery for your scan.

B. During your HR CT Chest scan


When you are transferred to the CT room you will be made comfortable on the examination table. The examination table slides you into the centre of the CT machine and some preliminary pictures are taken to confirm the scan position.

A member of our medical imaging specialist team will indicate when to breathe in, breath out or hold your breath to ensure the most accurate pictures.

The scan will take between 10-15 minutes.
