Figures
- FIGURE 1.
Lesion delineation in lower and middle left lobes was better on pinhole imaging at 10 min (A) and 2 h (B) than on parallel-hole imaging at 2 h (C), which had inconclusive findings. High noise level on SPECT images (D) precluded identification of parathyroid lesions.
- FIGURE 2.
Four lesions are found on pinhole imaging (at 10 min [A] and 2 h [B]), but only 2 lesions are found on high-resolution parallel-hole imaging (C) and SPECT (D).
