It's used sometimes, maybe in conjunction with other exams and tests depending on location and what they're looking for. Mine were used when doing a FNAB, which I had about 8 of them, checking the stomach/kidney/liver after pains or out if range test results, legs for DVT, and checking the carotid arteries where it was called a Doppler. I forget what the specificity, accuracy and sensitivity are for the cervical lymph nodes, but thought I recall it being fairly high, maybe even more so than a PET/CT scan in certain aspects, and palpable exam.
