Indeterminant thyroid nodule

A nodule of the thyroid may be benign or could potentially be malignant. As a general rule, the more irregular features and growth a nodule has, the greater the probability it is malignant. Statistically, greater than 50% of nodules are benign. Multiple nodules have a lower risk of cancer and are commonly associated with goitre. Unfortunately it is not possible to determine the exact nature of a nodule from a single MRI scan. There is a risk assessment categorization procedure that has been developed for ultrasound called TI-RADS which is the best way to evaluate the risk of an indeterminant nodule being malignant.
