The Great Contrast Shortage of 2022-Lessons learnt in Australia.

Introduction: Computed tomography (CT) imaging is one of the most commonly used diagnostic tools. Iodine-based contrast media (IBCM) are frequently administered intravenously to improve soft tissue contrast in a wide range of CT scans. Supply chain disruptions triggered by the SARS-CoV-19 pandemic led to a global shortage of IBCM in mid-2022.

The emerging association between bronchiectasis and systemic sclerosis: assessing prevalence and potential causality.

Background: Bronchiectasis has been observed in association with systemic sclerosis (SSc). Theorised aetiology includes aspiration related to oesophageal dysmotility, immunosuppressant medication use and the direct effect of collagen deposition on airway calibre.

Aims: To detail bronchiectasis prevalence in an SSc population who have had a high-resolution computed tomography (HRCT) of the thorax.

Low volume contrast CTPA in patients with renal dysfunction.

Introduction: The study aims to evaluate a method for and technical feasibility of performing CT pulmonary angiography (CTPA) with just 30 mL of contrast.

Methods: Twenty-four patients with renal dysfunction suspected of having pulmonary embolus underwent CTPA using 30 mL of contrast. A modified acquisition protocol was employed where sequential monitoring of the central superior vena cava (SVC) was performed following injection of contrast.
