Brief summary

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.

Interventions

DEVICEElectrical 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.
