title: Retrosternal Goiter Visualized on 99mTc Pertechnetate SPECT/CT, But Not on Planar Scintigraphy.
abstract: Retrosternal goiter is one of the common causes of anterior mediastinal masses. Scintigraphic diagnosis of retrosternal goiter plays an important role in avoiding invasive diagnostic procedures, and SPECT acquisition may enhance the diagnostic sensitivity of this technique as compared with planar scintigraphy. Here, I report a case of retrosternal goiter that was demonstrated on SPECT/CT obtained with Tc pertechnetate, but not on planar scintigraphy with the same tracer.
