|Official Title:||Electrical Impedance Scanning of Thyroid Nodules Prior to Thyroid Surgery: a Prospective Study|
|Study Start Date :||January 2002|
|Actual Study Completion Date :||December 2007|
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.
- Sensitivity and specificity of EIS [ Time Frame: 5 years ]
- NPV and PPV of EIS of the thyroid [ Time Frame: 5 years ]
Biospecimen Retention: None Retained
