Why is my scan not scheduled within SGH campus?

We have satellite imaging centres (for example, Camden Medical Centre) and collaborate with other SingHealth Institutions and select private imaging centres to provide high quality imaging for you more expediently.

Am I allowed to go to a private imaging centre on my own to get my scans done?

Please consult your clinician before you do so. Apart from the private imaging centres that we specifically collaborate with, we do not have an overview of how the imaging is performed and cannot ensure their image quality.
