title: Utility of SPECT/CT as an adjunct to planar whole body I-131 imaging: liver metastasis from papillary thyroid cancer.
abstract: One of the major limitations of planar I-131 imaging is its lack of anatomic precision. SPECT/CT offers the benefit of precise anatomic localization that planar imaging lacks. Whether for confirmation of physiologic uptake or true pathology, SPECT/CT has an important role to play in clarifying equivocal findings. We present a case of papillary thyroid cancer metastatic to the liver, a relatively rare scenario. SPECT/CT allowed definitive lesion characterization at the time of the patient's visit to the nuclear medicine department.
