Figure 1: Early (A) and late (B) planar views of dual-phase technetium 99m methoxyisobutylisonitrile parathyroid scintigraphy. A parathyroid lesion, which later confirmed as parathyroid adenoma, showed rapid radiopharmaceutical washout. Early planar view showed the lesion (A, arrow). Transaxial (C), sagittal (D) and coronal (E) slices of single photon emission computed tomography study (with 64×64 matrix) which was reconstructed with iterative reconstruction algorithm. The focus was detectable neither on late planar view nor on single photon emission computed tomography study with both reconstruction algorithms (patient no: 42, [Table 1]).
