Radiology departments face rising imaging volumes, growing complexity of examinations and increasing pressure to deliver accurate reports efficiently. While artificial intelligence has been adopted to assist with specific detection or triage tasks, such narrow systems have clear limitations when deployed at scale. They often duplicate costs, fragment...Read more

Low-dose CT screening aims to find lung cancer earlier, but the value of artificial intelligence as an independent reader depends on how reliably it flags scans with risk-dominant nodules and assigns the correct nodule type. An evaluation of baseline screening in a Chinese general population compared reconstruction choices to see how they affect...Read more

Accurate identification and quantification of lung cancer lesions is critical for diagnosis, staging, treatment planning and disease monitoring. While primary tumours receive most attention in radiological evaluations, patients often present with multiple lesions that must also be assessed for a complete picture of disease burden. Traditional...Read more

Accurate protocol selection for abdominal CT examinations is a critical component of radiology practice. Appropriate configuration of acquisition parameters and effective use of contrast media depend on choosing the correct protocol, which directly influences diagnostic precision and clinical outcomes. Despite its importance, the task of protocolling...Read more

Breast cancer, the most prevalent malignancy in women worldwide, is categorised into four molecular subtypes based on receptor expression: luminal A, luminal B, HER2-enriched and triple-negative breast cancer (TNBC). These classifications guide therapeutic decisions and impact prognosis. Conventional methods of determining subtypes rely on biopsy-based...Read more
