Abstract：Objective To investigate the value of ultrasound elastography(UE)combined with ultrasonography(CEUS)and conventional ultrasound in the diagnosis of superficial lymphatic tuberculosis lesions and the agreement with pathological find-ings.Methods 135 patients with suspected superficial lymphatic tuberculosis were selected and examined by UE,CEUS and conventional ultrasound.The results of the ultrasound examinations were counted and the value of UE+CEUS and conventional ultrasound in the diagnosis of superficial lymphatic tuberculosis was compared and analyzed,using the pathological findings of puncture as the"gold standard",as well as the detection rate of calcification by UE+CEUS and conventional ultrasound and the consistency of the diagnosis of superficial lymphatic tuberculosis of different types with the pathological findings.Results The sensitivity,specificity and accuracy of UE+CEUS in diagnosing superficial lymphatic nodule lesions were 97.96%,91.89%and 96.30%,respectively,of which the sensitivity and accuracy were higher than those of conventional ultrasound,and the differ-ence was statistically significant(P<0.05);the detection rate of calcification by UE+CEUS(100.00%)was higher than that of conventional ultrasound(86.96%),and the difference was statistically significant(P<0.05).The Kappa value for the concor-dance between UE+CEUS diagnostic lesion lymph node typing and pathological findings was 0.941(95%CI 0.816-1.066),with a compliance rate of 95.83%(P<0.05).Conclusion The sensitivity and accuracy of UE+CEUS in diagnosing superficial lymphatic tuberculosis lesions were significantly higher than those of conventional ultrasound,and calcified foci could be accu-rately detected,and the consistency of diagnosing superficial lymphatic tuberculosis lesion sites,staging and pathological find-ings was higher.
