flownetters and vascular surgery discussion listers- as the scanners get better, we vascular surgeons, traditionally more interested in the hemodynamics than the image, have nevertheless been faced with thyroid abnormalities in an astounding fraction of patients sent for carotid duplex scans- our primary care physicians have been faced with the difficult question of which lesions to pursue and which to ignore- i have consulted several ultrasound texts, but have been unable to find anything beyond technique- any suggestions how to educate myself to be able to tell my colleagues which lesions are likely benign and which are likely malignant? joe Joseph R Schneider Web Page http://pubweb.acns.nwu.edu/~jschneid/JRS.HTML "The cemeteries are filled with indispensable men." de Gaulle
