Osteoporosis remains underdiagnosed and undertreated despite established screening pathways. Many eligible patients are not referred for testing, and fracture risk is often misclassified when bone mineral density is assessed with dual-energy X-ray absorptiometry. Routine CT examinations offer a chance to evaluate trabecular bone without additional imaging,...Read more

Chronic obstructive pulmonary disease is heterogeneous, with emphysema, chronic bronchitis and recurrent exacerbations driving morbidity. Global cases among adults are projected to rise by 23% from 2020 to 2050, approaching 600 million, underscoring the need for tools that characterise disease beyond spirometry. Chest CT has become central to...Read more

Lung cancer remains the most common cancer worldwide, with non-small cell lung cancer accounting for the majority of cases. Among these, lung adenocarcinoma is often characterised by epidermal growth factor receptor (EGFR) mutations, which are critical for guiding treatment with tyrosine kinase inhibitors. These targeted therapies can significantly...Read more

Pancreatic ductal adenocarcinoma remains one of the deadliest malignancies, largely due to its frequent diagnosis at advanced stages. While contrast-enhanced computed tomography remains the standard imaging method for pancreatic cancer evaluation, nearly 40% of early-stage tumours can still go undetected. Deep learning approaches have emerged...Read more

Small renal masses (SRMs), frequently detected through imaging, are often managed through active surveillance. This approach involves serial monitoring using contrast-enhanced CT, which is widely used due to its diagnostic precision, availability and speed. However, the repeated imaging required over time raises concerns about cumulative radiation...Read more

Cervical spine fractures can lead to severe complications if left undetected, making accurate diagnosis a critical component of trauma care. However, interpreting CT scans in high-pressure environments often results in missed fractures, especially when scans involve thousands of images. Traditional re-evaluation methods using human reviewers fail...Read more

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and a significant cause of cancer-related mortality globally. Early-stage HCC offers better treatment prospects compared to advanced cases, yet predicting tumour growth rates remains a major clinical challenge. Tumour volume doubling time (TVDT) can vary significantly among individual...Read more

Stroke remains a leading global health concern, ranking as the second most common cause of death worldwide. Among the various types of strokes, acute anterior-circulation large vessel occlusion (LVO) strokes are particularly challenging, often leading to severe disability or death. The advent of endovascular thrombectomy (EVT) has revolutionised...Read more

In locally advanced pancreatic cancer (LAPC), preventing local progression is crucial as it significantly impacts survival rates. Intraoperative radiotherapy (IORT) has shown promise in improving local disease control rates. However, determining the risk of progression in patients initially assessed as stable disease (SD) after IORT remains challenging....Read more
