| Abstract: | We assessed the ability of the resistive index (RI) and pulsatility index (PI) to allow differentiation between normal, reactive, and neoplastic lymph nodes. Forty-seven medial iliac and 54 mesenteric lymph nodes from 83 dogs were evaluated sonographically. A cytologic sample was obtained in each dog that allowed categorization into one of the categories defined above. We found a significant difference in the RI and PI in nonneoplastic vs. neoplastic medial iliac and mesenteric lymph nodes. Values higher than 0.67 for the RI and 1.02 for the PI in medial iliac lymph nodes and higher than 0.76 for the RI and 1.23 for the PI in mesenteric lymph nodes had a high sensitivity and specificity for differentiating benign from neoplastic lymph nodes. |
