Your heart health matters, and getting a detailed look at your heart's arteries does not have to mean a hospital visit.

Castle Hill Diagnostics offers Cardiac CT (CT Coronary Angiography), a non-invasive scan that provides a detailed view of the coronary arteries. It is performed right here in our practice using the latest CT technology — no surgery, no overnight stay.

Our Cardiac CT service is led by Dr Arunima (Aru) Gupta, who has extensive experience in cardiovascular imaging, so the reporting of your scans is in trusted hands.

If your GP or specialist has concerns about your heart health, ask them whether a Cardiac CT is right for you. We accept all request forms.

Our services also include x-ray, CT, ultrasound, mammography, DEXA / BMD, interventional and pain management procedures, and MRI.

On-line appointments are available via our website or call us on (02) 8600 1400.

MRI APPOINTMENTS NOW AVAILABLE!!

Our NEW MRI service will commence on Monday 18th May.

The MRI scanner has been delivered, installed, and is now in its final commissioning phase within our new modern facility delivering quality services to the Hills District community.

We are always looking for ways to deliver more for our patients. That's why we chose a highly advanced MRI machine that delivers high-quality images with much shorter examination times than older machines. Its open / wide bore design also means greater comfort, less anxiety and an overall better patient experience with NO RADIATION.

You can make your appointment by calling us on (02) 8600 1400 or on-line appointments are also available via our website.

We have some EXCITING NEWS to share!

Castle Hill Diagnostics has recently doubled its size to accommodate our brand-new state-of-the-art MRI machine.

Now spanning across two modern facilities but from the same location, our vision was to create a practice that puts patient care, privacy and comfort front and centre and ensures our community has access to high quality imaging using the latest technology but at an affordable price. We believe our expansion is a further positive step toward this.

What's NEW? New MRI service, new Ultrasound equipment, better access, increased capacity, and generally an improved patient experience.

What's not NEW? Same location with the same dedicated team who have a strong commitment to delivering quality-centric and personalised care.

Most Medicare-eligible examinations are bulk billed.

On-line appointments are available via our website or call us on (02) 8600 1400.
