Article Figures & Data
Figures
- FIGURE 1.
Neck and background count estimation by camera-based method. Bkg = background; roi = region of interest.
- FIGURE 2.
A 57-y-old woman who had differentiated thyroid carcinoma and skeletal metastasis (after one previous therapy). Increased stomach and salivary gland uptake is seen. Probe-based method is positive for neck uptake, but camera-based method and scan are negative.
- FIGURE 3.
A 67-y-old woman who had differentiated thyroid carcinoma and shoulder metastasis. Probe-based method is positive for neck uptake, whereas scan and camera-based methods are negative.
- FIGURE 4.
Measurements obtained through camera-based and probe-based methods are highly concordant, with Pearson correlation coefficient of 0.97.
- FIGURE 5.
Pairwise comparison between camera-based, probe-based, and scan findings to detect positive and negative cases.
