Summary
This study looks at 400 women recently diagnosed with breast cancer to compare four imaging techniques: MRI, digital mammogram, ultrasound, and PET scan. The goal is to see which method, or combination, best determines how far the cancer has spread before surgery. The results could help doctors choose the most accurate imaging for staging breast cancer.
