  Purpose

Patients over the age of 18 with thyroid nodules scheduled for surgery will undergo EIS scan. Each node will be scanned and graded form 1-5 (1=benign, 5=malignant). Results will be compared with final histopathology.

Groups/Cohorts Assigned Interventions
A

This is a a single arm study evaluating the efficacy and accuracy of EIS in detecting malignant thyroid nodules.

PAtients with thyroid nodules scheduled for surgery will undergo EIS examination.

Device: Electrical Impedance Scanning (EIS) of the Thyroid gland
Patients will be examined in the supine position. A cylinder electrode conveying 2.5V electrical current will be held by the patient. The patient will be scanned by a probe (similar to an ultrasound probe. The examination takes 5 minutes and there is no risk or discomfort.
