Precision Imaging.
Expert Care.
Artery & Vein Diagnostics is a specialist vascular imaging clinic with locations in Macquarie Park and Kingswood. We combine advanced ultrasound technology with on-site vascular surgical expertise to deliver diagnostic imaging of the highest standard.
Built Around Clinical Excellence
Artery & Vein Diagnostics was established with a clear purpose: to provide referring clinicians and their patients with access to specialist-level vascular imaging that is accurate, timely, and clinically meaningful.
What sets us apart is the presence of an on-site vascular surgeon who oversees and interprets every study. This means reports are not simply descriptive — they are clinically contextualised, graded to current guidelines, and directly useful for treatment planning.
We serve patients across Western and Northern Sydney from our two clinic locations, and we are committed to making specialist vascular imaging accessible through Medicare bulk billing for all eligible patients.
Our Values
Clinical Excellence
Every study is performed by accredited sonographers and interpreted by our on-site vascular surgeon, ensuring the highest standard of diagnostic accuracy.
Rapid Reporting
We understand that timely results matter. Our 24-hour report turnaround means referring clinicians can act quickly and patients receive answers without unnecessary delay.
Patient-Centred Care
We take the time to explain procedures clearly, ensure patient comfort, and deliver results in a way that is meaningful and accessible to each individual.
Collaborative Practice
We work closely with referring clinicians, vascular surgeons, and GPs to provide integrated care that supports the best outcomes for every patient.
Meet the Specialists
Our team combines vascular surgical expertise with highly skilled accredited sonographers to deliver imaging of the highest clinical standard.

Dr Gaorui (Gary) Liu
PhD (USYD) · Fellow ASA · RPhS (Registered Phlebology Sonographer) · AMS · Adjunct Honorary Lecturer, WSU
Gary is a distinguished vascular sonographer and clinical leader whose career spans advanced diagnostic imaging, research, and professional education. He previously served as Section Chief of the Vascular Laboratory at Nepean Hospital and Senior Vascular Sonographer at the Western Sydney Vascular Laboratory, leading clinical standards and innovation across multiple sites.
In 2026, Gary completed his PhD at the University of Sydney, strengthening his expertise in phlebology ultrasound and clinical research. He is a Fellow of the Australasian Sonographers Association (ASA), holds the RPhS credential through Cardiovascular Credentialing International, and is an Adjunct Honorary Lecturer at Western Sydney University.
As a scholar, Gary has 9 SCI-indexed journal publications, authored book chapters, and contributed to the English-to-Chinese translation of Strandness's Duplex Scanning in Vascular Disorders — the foundational text in vascular sonography. He led the ASA's development of a national evidence-based chronic venous insufficiency ultrasound guideline and holds a special interest in the CHIVA technique for venous insufficiency. He was also awarded Researcher of the Year 2026 by the ASA.
