Color Doppler imaging in the assessment of vascular involvement by pancreatic carcinoma.

Abstract

Color Doppler imaging is a sensitive and highly specific technique in assessing vascular involvement by pancreatic cancer when absence of contact or vascular encasement is seen. When vascular encasement is detected by color Doppler imaging, a definitive diagnosis of unresectability can be made, and further diagnostic procedures can be avoided. When sonography is used in the initial evaluation of pancreatic cancer, color Doppler imaging can improve the selection of patients for further diagnostic examinations or surgical exploration.
