Reliable SPECT/CT quantification fuels increase in therapeutic nuclear medicine procedures.

With more than 1,150 publications referencing theranostics in 20171, there is clear momentum in this fast-growing area of medicine. Combining diagnostics and therapy brings new opportunities for delivering the right treatment at the right time to each patient. But having reliable patient-specific data is essential for achieving this. Traditional SPECT/CT quantification, while promising, is unfortunately cumbersome and inexact—thus rarely used.

The world’s most robust2 SPECT/CT quantification
Automated, precise, and reproducible to within 5%2, xSPECT Quant™ provides the degree of standardized SPECT/CT quantification needed for theranostics and radionuclide therapy. Unrivaled in its level of accuracy3, xSPECT Quant lays the foundation for optimal therapy planning and management.

Specifically designed for 177Lu-based theranostic applications, xSPECT Quant makes it possible to routinely measure early disease response and pinpoint dose activity concentration. Thus helping you better treat and monitor each patient.

What experts say

“As a guest editor for The Journal of Nuclear Medicine, I had the chance to create a dedicated issue on theranostics. Bringing together and sharing our knowledge will only help propel its use. In my opinion, this is nuclear medicine‘s most exciting development since the introduction of PET and PET/CT.”
