CT Lung Assessment

A low-dose CT scan of the lungs with AI-assisted nodule detection, designed for early identification of lung abnormalities. The scan uses significantly less radiation than a standard diagnostic CT and is interpreted by both an AI detection system and a specialist radiologist for enhanced sensitivity.

Low-dose CT of the chest is the only screening modality proven to reduce lung cancer mortality in high-risk populations, and its application is broadening to include individuals with occupational exposure histories, persistent respiratory symptoms, or a family history of lung disease. This assessment uses a reduced radiation protocol — typically delivering around one to two millisieverts, comparable to several months of background radiation — while maintaining sufficient image quality to detect pulmonary nodules as small as a few millimetres. Vista Health's lung assessment incorporates AI-assisted nodule detection alongside standard radiologist review. The AI system flags potential nodules and categorises them by size and morphology, while the specialist radiologist provides the definitive clinical interpretation. This dual-review approach increases sensitivity for small or subtle findings that might be overlooked on a single-reader assessment. The scan is completed in approximately twenty minutes including positioning and breathing instructions. It is particularly relevant for current or former smokers, individuals with occupational lung exposure (asbestos, silica, industrial chemicals), those with a family history of lung cancer, and anyone experiencing persistent cough, breathlessness, or other unexplained respiratory symptoms. A clinical referral is required.
