Pancreatic cancer is among the most dismal of human malignancies. The 5-year survival rate is lower than 5%. The identification of precursor lesions would be the main step to improve this fatal outcome. One precursor lesions are called pancreatic intraepithelial neoplasia (PanIN) and are graduated in grade 1 to 3, whereas grade 3 is classified as carcinoma in situ. Currently, no reliable, noninvasive imaging technique (e.g., ultrasound, computed tomography, magnet resonance imaging) exists to verify PanINs.
