title: MIBG Activity in the Gallbladder.
abstract: Whole-body I-MIBG images were acquired in a 12-year-old girl who had metastatic malignant paraganglioma to assess the extent of the metastases. Image quality was suboptimal because of diffusely increased muscle activity, which was related to the labetalol the patient took to control her blood pressure. Despite the suboptimal images, a subtle activity in the lower border of the liver was noted, along with known lesions in the sacrum and upper chest. Further SPECT/CT images localized this activity in the gallbladder.
