Colorectal cancer (CRC) remains a leading global burden, with approximately 1.9 million cases and 0.9 million deaths recorded in 2020. Screening is central to prevention because removing adenomatous polyps can interrupt progression to malignancy. In many programmes, faecal immunochemical testing (FIT) is offered every two years, while CT colonography...Read more

Postoperative complications such as abdominal fluid collections present a considerable challenge for patient recovery and surgical outcomes. Detecting and treating these complications early is essential to prevent severe consequences including vessel erosion and infection. Imaging is a critical part of this process, yet traditional techniques...Read more
