{Reference Type}: Case Reports {Title}: Intrathoracic Goiter Visualized on iodine-123 and technetium-99m Single-Photon Emission Computed Tomography/Computed Tomography. {Author}: Kristensen MH;Abrahamsen J;Thomsen HH;Kristensen MH;Abrahamsen J;Thomsen HH; {Journal}: World J Nucl Med {Volume}: 20 {Issue}: 4 {Year}: Oct-Dec 2021 暂无{DOI}: 10.4103/wjnm.wjnm_90_21 {Abstract}: Goiter with an intrathoracic component is relatively common; however, it is less common to see extent outside the anterior or posterior mediastinum. We present a case of intrathoracic goiter of significant size and abnormal placement which is examined using both 99mTc-pertechnetate and iodine-123 single-photon emission computed tomography/computed tomography.
