Figures
- FIGURE 1.
123I-rose bengal cholescintiscan (left) and 99mTc-HIDA cholescintiscan (right).
- FIGURE 2.
Chemistry of 99mTc-HIDA radiopharmaceuticals: lidocaine (A) and 99mTc-mebrofenin (B). Two lidocaine analogs are bichelated to 99mTc by IDA.
- FIGURE 3.
Cystic duct sign. (A) 99mTc-HIDA scan ordered to rule out acute cholecystitis. Images show focal accumulation of activity medial to usual position of gallbladder, which remains mostly unchanged over time. (B) Ten-minute SPECT/CT image in same patient shows that focal activity is in cystic duct just distal to occluding cystic duct stone. (Reprinted with permission of (27).)
- FIGURE 4.
Comparison trial of multicenter sincalide infusion method. Box plots show distribution of GBEF values for 3 different infusion groups for different lengths of infusion time. The 60-min infusion had the highest GBEFs and the lowest variability. Boxes represent interquartile range (25th−75th percentiles, median line in center, mean is square), bars represent fifth and 95th percentiles, ×s represent first and 95th percentiles, and dash is minimum and maximum.

- FIGURE 5.
Study ordered to confirm or exclude biliary atresia. (A) Six-hour 99mTc-HIDA planar static image shows equivocal gallbladder filling and biliary-to-bowel transit. (B) Ten-minute SPECT/CT acquisition confirms activity in gallbladder, excluding biliary atresia. (Reprinted with permission of (27).)
