99mTc-Pertechnetate-SPECT/US Hybrid Imaging Enhances Diagnostic Certainty Compared With Conventional Thyroid Imaging With Scintigraphy and Ultrasound

Evaluation of thyroid ultrasound and 99m Tc-pertechnetate scintigraphy side by side frequently produces ambiguous results regarding the correct assignment of anatomy and functionality of a nodule. We describe the usefulness of 99m Tc-pertechnetate-SPECT/US-fusion imaging. A 75-year-old woman was referred for exclusion of cold nodules. After conventional diagnostics (in vitro thyroid parameters, B mode–US, planar 99m Tc-pertechnetate-thyroid...
