Potentials of ultrasound diagnosis for thyroid cancer recurrences

The paper presents diagnostic potentials of ultrasound examination using Siemens Acuson S 2000 ultrasound system with multifrequency sensors of 3-5 MHz, 4-7,5 MHz and 9-13 MHz in B-mode applying techniques of color Doppler mapping, 3D-image image reconstruction and sonoelastography for detection of thyroid cancer recurrence in 220 patients. The following signs indicating the regional recurrence of thyroid cancer have been identified: non-homogenous structure of lymph nodes, low intensity reflections, red coloring at sonoelastography and others. Ultrasound examination may be the method of choice in solving the problem regarding the development of recurrence, extent of local tumor involvement, presence of lymphogenic metastases and for the detection of postoperative complications
