This study indicates a promising method for the treatment of superficial bladder cancer. Although the mean initial tumor uptake was high, effective therapy of bladder tumors will require an increased retention of the cytotoxic radionuclide in tumor tissue.

In a prospective study we investigated 12 clinical features for scaphoid fractures in 52 patients: 23 in whom a fracture of the scaphoid was diagnosed radiologically and 29 patients in whom a fracture was clinically suspected but could not be confirmed by radiography or scintigraphy. The signs were tested within a few days of injury and again 2 weeks later. None was reliable in diagnosing a scaphoid fracture.

In a prospective study we performed bone scans on 84 patients who had sustained a wrist injury and in whom a scaphoid fracture was clinically suspected but could not be confirmed on the original set of five routine "scaphoid view" radiographs. In 40 patients the bone scan was normal and in 25 there was increased uptake in areas other than the scaphoid. In 19 there was localized increased uptake in the scaphoid bone. In seven of these a scaphoid fracture was subsequently demonstrated on repeat radiographs (five cases) or a CT scan (two cases). In the remaining 12 no fracture could be demonstrated.
