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.
