Abstract Seventeen cases in which red blood cells (RBCs) were labeled with99mTc (99mTc-RBC method) are reviewed to confirm the vascular nature of lesions. This study was undertaken to see whether the99mTc-RBC method is useful in terms of detecting angiomatous lesions, and also to determine the indications for this method. In one case, total removal revealed a good, correlation between the range of uptake and the actual tumor size. MR images definitively demonstrated tumor location and extension. When hemangioma is suspected, MR examination is the preferred modality to determine tumor extension, tumor mass, and invasion into the surrounding tissue. However, when it is suspected that the MR image is poor due to bulky metal artifacts, as in the case of dental prostheses, the99mTc-RBC method should be used because this method is only slightly influenced by metal artificts. In addition, this method should be applied when whole body screening is needed.
