title: Use of whole-body imaging using Tc-99m RBC in patients with soft-tissue vascular lesions.
abstract: We investigated the usefulness of whole-body imaging as an adjunct to spot imaging in soft-tissue vascular lesions, such as hemangiomas and vascular malformations. Spot imaging of the known lesion and whole-body imaging were performed 1-3 hours after the injection of Tc-99m RBC in 42 patients with soft-tissue vascular lesions. Whole-body imaging was considered to be useful in only two patients, who had multiple distant occult lesions in addition to large known lesions. It was suggested that the routine addition of whole-body imaging is not cost effective in patients with soft-tissue vascular lesions, although it may be beneficial for detecting occult lesions in patients with hemangiomas.
