Navigating Scans: What CT, MRI, and PET Scans Tell Your Medical Team

High-resolution radiological scans are critical tools in modern oncology. They provide detailed anatomical and metabolic maps that guide radiation contouring, surgical planning, and response monitoring. • Uses cross-sectional X-rays enhanced by intravenous contrast dye. • Evaluates tumor size, lymph node enlargement, and anatomical relationships in lungs, abdomen, and pelvis. • Uses magnetic fields and radio waves without ionizing radiation. • Superior soft-tissue contrast, ideal for brain, spinal cord, head & neck, and pelvic organ imaging. • Combines CT imaging with a tiny amount of radiotracer (FDG) to detect metabolic activity in active tissue. • Helps identify distant spread (metastasis) and evaluates response following completion of chemotherapy or radiation.
