RAI thyroid bed uptake after total thyroidectomy: A novel SPECT‐CT anatomic classification system

Recent, more selective use of radioactive iodine (RAI) has led to reevaluation of the clinical importance of achieving complete total thyroidectomy with minimal residual normal thyroid tissue. We utilize the improved localization by post‐RAI remnant ablation, single photon emission computerized tomography‐computed tomography (SPECT‐CT) to define specific anatomic sites of residual RAI‐uptake foci after total thyroidectomy for differentiated thyroid cancer (DTC) and to provide a novel classification system relating uptake to thyroid anatomy and preservation of adjacent neural structures.
