QuiremScout®

Imageable microspheres for SIRT work-up

A personalized approach to SIRT

Visualizing SIRT success from the start

QuiremScout® is used to safely evaluate the distribution of intra-arterially injected microspheres prior to performing SIRT. The insights gained with QuiremScout® can be used by the treating physician to make an informed decision about the expected safety and efficacy of the SIRT procedure. Studies show that lung-shunt and intrahepatic distribution can be more accurately assessed with QuiremScout® compared to the commonly used surrogate Tech-99m-MAA.

QuiremScout® in a 73-yo female HCC-patient

QuiremScout® - Case example

A 73-yo female patient suffering from HCC received a scout dose of Holmium-166 microspheres (QuiremScout®) prior to SIRT. The distribution of the scout dose microspheres was used to evaluate the safety/efficacy profile of the SIRT treatment.

Scout Therapy

QuiremScout® is indicated for patients that are eligible for SIRT treatment of liver tumors.

QuiremScout® is intended for evaluation of lung-shunt, extrahepatic deposition and intrahepatic distribution of intra-arterially injected microspheres.

QuiremScout® is contraindicated for patients that

  • are not eligible for SIRT;
  • have uncorrectable abnormal vascular anatomy that would result in significant reflux of hepatic arterial blood to the lungs, stomach, pancreas or bowel;

Using microspheres as scout

Personalized SIRT, it starts with QuiremScout®

The effectiveness and safety of SIRT depends on numerous patient related factors, such as anatomy, tumor blood supply, tumor type and tumor staging. It is therefore essential that the expected SIRT treatment outcome is evaluated for each patient individually. QuiremScout® is used to simulate the SIRT treatment, using a safe dose of microspheres identical to those used for the therapy. The QuiremScout® scan can be used by the clinical team to make an informed and patient-specific clinical decision whether SIRT is likely to be beneficial.
