Abstract
Radioembolization is usually performed with microspheres containing yttrium-90 (90Y). Holmium-166 (166Ho)-microspheres were developed as an alternative new product for radioembolization.
The unique characteristics of 166Ho-microspheres allow for improved imaging possibilities. They can be visualized and
quantified, already at low numbers and activities, to predict treatment distribution
using 166Ho-microspheres at scout quantity during pre-treatment simulation. The option to reliably
predict the distribution of microspheres provides physicians control over the treatment,
allowing them to select and treat patients with a personalized treatment plan. Safety
and efficacy were established in several clinical studies. 166Ho-microspheres radioembolization aims to optimize individualized treatment planning
in order to improve treatment outcomes.
