[99mTc marking of gel foam for catheter embolisation (author's transl)]. / 99mTc-Markierung von Gelatineschwamm für die Katheterembolisation.

ABSTRACT

A simple method is described for marking gel foam particles with 99mTc after reduction of the pertechnetate. This is carried out in the Luer lock syringe to be used for the injection. After embolisation and control angiography, the patient is placed under a scintillation camera. The position of the embolising material can then be demonstrated scintigraphically. In six patients marked emboli were found to be correctly placed. In another patient undergoing a second embolisation for a renal tumour, particles were found in the peripheral circulation.
