Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Percentage of liver volume for which the accumulation of SIR spheres was correctly predicted by the preceding Tc-99m MAA scintigraphy
Tidsramme: Tc-99m MAA scan one day prior to radioembolisation; Bremsstahlen-Scan after SIR spheres therapy
|
The percentage in liver volume for which the accumulation of SIR spheres during therapy was correctly predicted by Tc-99m MAA will be given by a blinded reader in categories by visual assessment (0-10%, >10-20%, >20-30%, …, >90-100%) (only patients who received Tc-99m MAA during evaluation.)

Tc-99m MAA scan one day prior to radioembolisation; Bremsstahlen-Scan after SIR spheres therapy
