Quality estimation method of preoperative ultrasound diagnostics local and regional spread of cancer of thyroid gland

摘要

A method of evaluating the quality of the pre-operative ultrasound diagnostic local and regional spread of thyroid cancer, comprising determining and comparing sensitivities preoperative ultrasonic diagnostic local and regional spread of thyroid cancer in the test and control groups, characterized in that in a first step determine the most significant ultrasound criteria for evaluation local and regional spread of thyroid cancer: A - suspected metastatiches th lymph nodes in the neck; E - suspected extrathyroidal invasion; M - multicentric suspected lesion thyroid parenchyma, which will be evaluated diagnostic quality; in the second step is isolated and studied a control group of patients that compared the quality of the pre-operative ultrasound diagnostic local and regional spread of thyroid cancer; the third phase of the study group carried out the calculation of the sensitivity index Ppo each individual criterion, somewhere sensitivity index criterion L, which is calculated according to the formula, the number of matches somewhere ultrasound suspicion of metastases to regional lymph nodes in the treatment group with those of postoperative histology in this group - the number of cases in which there were ultrasound suspicion of metastases to regional lymph nodes in the study group, but postoperative istologicheskoe study did not confirm the existence of this criterion in this group - the number of cases in which from the
