Why have a Cat scan of abdomen for swollen lymph nodes?

A CT scan of the abdomen is often performed for swollen lymph nodes to provide detailed images that help identify the underlying cause of the swelling. It can reveal abnormalities such as tumors, infections, or inflammatory conditions affecting the lymph nodes or surrounding tissues. This imaging technique aids in diagnosis, treatment planning, and monitoring of any changes over time. Additionally, it helps differentiate between benign and malignant processes.
