Value of the Combination Ultrasonography With Ti-RADS Score / Dual Tracer Scintigraphy MIBI-Tc99m/Iodine-123 in the Detection of Malignancy of Thyroid Nodules (≥15 mm) Classified Bethesda III or IV on Cytology (MIBI-THYR)

Value of the Combination Ultrasonography With Ti-RADS Score / Dual Tracer Scintigraphy MIBI-Tc99m/Iodine-123 in the Detection of Malignancy of Thyroid Nodules (Sup or Egal to 15 mm) Classified Bethesda III or IV on Cytology

The main objective of the study is to show that the addition of ultrasonography to the dual tracer scintigraphy MIBI-Tc99m/Iodine-123 will increase (at least +5%) the negative predictive value compared to the dual tracer scintigraphy alone in detection of malignancy in thyroid nodules ≥15 mm classified as Bethesda III-IV on cytology.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
