B-Mode Sonography and Doppler ultrasound in characterizing thyroid nodules and its correlation with pathological diagnosis
Dr. Amitkumar J Choudhari and Dr. Nijalingappa
The first diagnostic application of ultrasound occurred in 1942. In a paper entitled “Hyperphonagraphy of the Brain,” Karl Theodore Dussic reported localization of the cerebral ventricles using ultrasound. Unlike the current reflective technique, his system relied on the transmission of sound waves, placing a sound source on one side of the head, with a receiver on the other side. A pulse was transmitted, with the detected signal purportedly able to show the location of midline structures. While the results of these studies were later discredited as predominantly artifact, this work played a significant role in stimulating research into the diagnostic capabilities of ultrasound. This was a prospective study to evaluate if nodule/s is/are benign or malignant by ultrasonography and Doppler study and pathological correlation in atleast 50 patients referred in view of clinically / incidentally (Carotid Duplex Doppler / neck ultrasound for non thyroid pathologies) detected goitre / thyroid nodule. Of the total 59 cases of thyroid nodules associated with lymphadenopathy, 1 (1.69%) lymph node with loss of central echogenic was pathologically proven to be lateral aberrant thyroid due to papillary thyroid carcinoma metastases. One (1.69%) case of thyroid malignancy associated with lymphadenopathy showed preservation of central echogenic hilum. Six (10.17%) cases of benign had associated lymphadenopathy with loss of central echogenic hilum and 51 (86.44%) benign cases had intact central hilum. The sensitivity of association of lymph node with loss of central echogenicity with thyroid malignancy was 50% and specificity was 89.5%.
