Fig. 4

Early phase of coronal SPECT (A), coronal CT (B), coronal SPECT/CT (C) and MIP (D) images from 99mTc-MIBI displaying a clear thyroid image (dotted arrow), with focal imaging agent concentration below the inferior pole of the left lobe (arrow). Delayed phase of coronal SPECT (E), coronal CT (F), coronal SPECT/CT (G) and MIP (H) images showed significant tracer washout from the thyroid (dotted arrow) while high concentration persisted in the lesion below the inferior pole of its left lobe (arrow). MIP is maximum intensity projection
