title: Tolazoline-augmented arteriography in the evaluation of bone and soft-tissue tumors.
abstract: Twelve patients with bone tumors were prospectively evaluated by arteriography both with and without tolazoline. In general, tolazoline improved definition of tumor extent; however, in 2 patients with highly vascular tumors and 2 patients with hypovascular tumors, tolazoline did not improve visualization. In 3 of the 12 patients, the tolazoline-augmented study was less accurate than the nontolazoline study in defining tumor extent.
