Preoperative us is very specific and accurate in diagnosing gross ete which impacts the extent of initial surgery for thyroid cancers. An ultrasound of the thyroid produces pictures of the thyroid gland and the adjacent structures in the neck. Indiscriminate evaluation of thyroid nodules with thyroid biopsy could cause a harmful epidemic of diagnoses of thyroid cancer, but inadequate selection of thyroid nodules for biopsy can lead to missed diagnoses of clinically relevant thyroid cancer. Ultrasoumd is very much operator dependent, more so than other imaging methods so the operator needs to be very good and experienced in the area being imaged.

Only then is it a fantastic technology. It can also show whether a nodule has any features that suggest it may be a thyroid cancer rather than a benign nodule, and whether the lymph nodes in the neck appear to be affected. It gives off sound waves and picks up the echoes as they bounce off the thyroid gland. The patient visited the gp with a newly presented lump in her neck. There are apparently some that an ultrasound can show to be very low risk and which therefore, may not be, but i think they are a minority. All the imaging has problems, pet can miss due to resolution or low image contrast, etc. Thyroid cancer is (comparatively) rare. I think about 90% or more of thyroid biopsies find nothing sinister. Ultrasound (us) risk stratification systems (rsss) have been developed to reduce the number of unnecessary fine needle aspirations (fnas) of thyroid nodules. The expert ultrasonographer will look for multiple changes. Ultrasound is very sensitive and shows many nodules that cannot be felt. The accuracy of this method in identifying malignant tumors is 95%, indicating the reliability and informativeness. I'm just saying some places don't even have that.
