Interventional radiology uses imaging guidance to perform selected diagnostic and therapeutic procedures. Depending on the condition, a specialist may guide a catheter, needle or other instrument to a specific area. The suitability of a procedure depends on the diagnosis, medical history and assessment by the treating team.
Onco-intervention includes image-guided procedures used in the management of selected cancers. Depending on the tumour and treatment plan, procedures may deliver therapy to a targeted area or help destroy tumour tissue. The appropriate option is determined by the cancer type, its extent and the patient's overall condition.
Diagnostic angiography helps assess blood vessels and identify abnormalities such as narrowing, blockage or other vascular changes. Imaging findings can support diagnosis and treatment planning. The specific technique and need for angiography depend on the suspected condition and the clinician's assessment.
Chemoembolisation is a targeted treatment used for selected tumours, most commonly in the liver. It combines delivery of chemotherapy to the tumour's blood supply with a technique that reduces blood flow to the treated area. Eligibility and expected benefit depend on tumour characteristics and the patient's health.
Radioembolisation is a specialised treatment that delivers tiny radioactive particles through blood vessels supplying certain liver tumours. It may be considered for selected patients as part of a wider cancer treatment plan. A multidisciplinary team assesses suitability, potential risks and other available options.
A nephrostomy involves placing a small tube into the kidney through the skin to drain urine when normal drainage is obstructed or needs to be bypassed. Imaging guidance helps the clinician position the tube. The reason for the procedure, expected duration and aftercare depend on the underlying condition.
Biliary stenting may be used to help keep a bile duct open when it is narrowed or blocked. The procedure can support bile drainage and may be considered in selected benign or cancer-related conditions. The approach and follow-up plan depend on the cause and location of the obstruction.
Uterine artery embolisation is a minimally invasive procedure used for selected uterine conditions, including symptomatic fibroids. It reduces blood flow to targeted tissue through a catheter-guided technique. A specialist evaluates symptoms, imaging results, reproductive plans and alternative treatments before recommending this option.
Image-guided tumour ablation uses imaging to direct a probe or needle to selected tumours and destroy targeted tissue. It may be an option for certain lesions depending on size, location and diagnosis. Treatment planning should consider the patient's overall health and other available cancer therapies.
Radiofrequency ablation uses heat generated by radiofrequency energy to destroy selected abnormal tissue. It can be used for some liver or lung lesions when clinically appropriate. Imaging helps guide the treatment, while the care team assesses procedural risks, expected outcomes and the need for follow-up.
Vascular access procedures create or establish access to blood vessels for selected treatments or medical needs. Imaging guidance may help the clinician position a catheter safely and accurately. The type of access, preparation and care after the procedure depend on the patient's condition and intended use.
CT, MRI, ultrasound and Doppler studies provide different views of internal structures, organs and blood flow. These tests can help investigate symptoms, assess disease and plan treatment. The most appropriate imaging method depends on the clinical question, the patient's history and the referring clinician's recommendation.
