Introduction: It is estimated that 8% of hospitalised patients require treatment from Interventional Radiology (IR). However, little is known about the potential impact of IR on regional and remote Australians, including Indigenous patients. This study aimed to assess treatments performed by IRs on regional/remote patients to predict future IR workforce and governance needs.

Background: Older individuals are at an increased risk of delayed recovery following a traumatic injury. Measurement of muscularity and frailty at hospital admission may aid with prognostication and risk stratification.
Objective: This study aimed to describe muscularity at intensive care unit (ICU) admission in patients admitted following trauma and assess the relationship between muscularity and clinical, long-term functional outcomes and frailty at ICU admission.
Inferior vena cava (IVC) filters are used in certain patients to help prevent the occurrence of pulmonary embolism (PE). IVC filters are generally recommended to be removed once PE prophylaxis is no longer required. Long-dwelling IVC filters are associated with higher complication rates (Vasa 2020; 49: 449), being more difficult to retrieve and associated with higher retrieval complications (Cardiovasc Diagn Ther 2016; 6: 632).

Despite calls for improvement at a "grass-roots" level, most IRs find that junior doctors have limited or no knowledge of IR, and thus reduced awareness of potential IR treatments for their patients or contemplating IR as a future career. The aim of this study was to survey current medical students to assess perception of whether a wider variety of medical schools are integrating IR into their curriculum, from universities all across Australia.

Purpose: To assess occlusion success and adverse events associated with the use of a self-expanding device for peripheral artery embolization.
Methods: This prospective, single-arm, feasibility study was conducted using the Caterpillar™ Arterial Embolization Device composed of opposing nitinol fibers and a flow-occluding membrane. Twenty patients (24 embolization sites) were treated at four investigational centers in New Zealand and Australia and followed for 30 days.
Objective: Haemorrhagic shock is a life-threatening complication of trauma, but remains a preventable cause of death. Early recognition of retroperitoneal haemorrhage (RPH) is crucial in preventing deleterious outcomes including mortality. Injury to the 9-11th intercostal arteries (i.

The aim of this study was to determine the incidence and treatment of MLLs at a level 1 trauma centre.
Methods: Single-centre retrospective cross-sectional study of consecutive patients with an imaging diagnosis of a Morel-Lavallee lesion from 1/1/2010-31/12/2019.
Purpose: To investigate the safety and efficacy of an aqueous polyethylene glycol-based liquid embolic agent, Embrace Hydrogel Embolic System (HES), in the treatment of benign and malignant hypervascular tumors.
Materials And Methods: A prospective, single-arm, multicenter study included 8 patients, 5 males and 3 females, with a median age of 58.5 years (30-85 years), who underwent embolization in 8 tumors between October 2019 and May 2020.

Introduction: There are few female Interventional Radiologists worldwide and this is a significant issue for many countries. There is little known about the current status and attitudes to women in Interventional Radiology in Australia and New Zealand. The purpose of this study was to explore the gender balance, workforce challenges and perceptions towards women in Interventional Radiology in Australia and New Zealand.

Patients with bronchial dilatation have been shown to be at increased risk of hemoptysis introducing the risk of airway obstruction. In this study from an academic tertiary referral center, we aimed to assess the incidence of massive hemoptysis in our CTEPH patients, the success of bronchial artery embolization (BAE), recurrence, and hemoptysis-related mortality.

Introduction: Incorporating artificial intelligence (AI) in diagnostic medical imaging reports has the potential to improve efficiency. Although perception of radiologists, radiographers, medical students and patients on AI use in image reporting has been explored, there is limited literature on non-radiologist clinicians' opinion on this topic.
Method: Single-centre online survey targeting non-radiologist medical staff conducted from May to August 2021 at a tertiary referral hospital in Melbourne, Australia.

Machine learning techniques, also known as artificial intelligence (AI), is about to dramatically change workflow and diagnostic capabilities in diagnostic radiology. The interest in AI in Interventional Radiology is rapidly gathering pace. With this early interest in AI in procedural medicine, IR could lead the way to AI research and clinical applications for all interventional medical fields.

Venogenic ED is elucidated as a cause in a subgroup of patients. The study aims to investigate the clinical success, technical success, safety and durability of venous embolisation for management of venogenic ED.

Treatment may involve a variety of interventions including observation, manual compression, ultrasound-guided thrombin injection and a variety of endovascular and surgical techniques. Current treatments are largely based on observational data and there is no consensus on management.

Introduction: Cataract formation is a tissue reaction effected by radiation exposure. The purpose of this study was to evaluate the occupational exposure to the lens of the eye of interventional radiologists (IR's) and interventional radiology staff, with and without lead glasses.
Methods: Ethical approval was provided by the hospital research and ethics committee.
Introduction: To compare the outcomes of proximal (pSAE) versus distal (dSAE) splenic artery embolisation for management of focal distal arterial splenic injuries secondary to blunt splenic trauma.
Method: Ethical approval was granted by the hospital research and ethics committee, Project 389/19. All patients who underwent splenic artery embolisation secondary to blunt abdominal trauma from 1 January 2009 to 1 January 2019 were reviewed.
Background: This study aimed to risk-stratify chest pain as a presenting symptom in patients with a diagnosis of pulmonary thromboembolism (PE) to assess for any association. In addition, this study aimed to assess traditionally acknowledged PE risk factors in an Australian population.
Methods: This was a retrospective single-centre cohort study assessing patients who presented to our emergency department during the period of 1 January 2019 to 1 January 2020.
Objectives: Changes in muscularity during different phases of critical illness are not well described. This retrospective study aimed to describe changes in computed tomography (CT)-derived skeletal muscle area (SMA) and density (SMD) across different weeks of critical illness and investigate associations between changes in these parameters and energy and protein delivery.
Methods: Thirty-two adults admitted to the intensive care unit (ICU) who had ≥2 CT scans at the third lumbar area performed ≥7 d apart were included in the study.
Background: As an adjunct to non-operative management, splenic artery embolization (SAE) has been increasingly utilized throughout the world and is now the standard of care for hemodynamically stable patients. This study aimed to retrospectively assess the rate of splenic salvage and complications after SAE for blunt trauma at a level 1 trauma center using the 2018 update to the AAST criteria, and further sub-stratify the role of angiography in AAST grade III injuries with significant hemoperitoneum. All patients between 1 January 2009 and 1 January 2019 who underwent blunt trauma and proceeded to embolization were included.
