xSPECT QuantReliable SPECT/CT quantification for clinical routine

xSPECT Quant

Conventional SPECT/CT quantification is manual and time intensive—often requiring specialized resources to manage the complexity and potential for error. As a result, quantitative SPECT/CT is rarely used clinically.

The only tool to offer automated, accurate, and reproducible quantification for a range of isotopes, xSPECT Quant™ has paved the way for routine SPECT/CT quantification.

xSPECT Quant uses a 3% National Institute of Standards and Technology (NIST) traceable precision source, which allows you to easily standardize uptake values across different cameras, dose calibrators, and facilities.

Accurate to within 5%,1 xSPECT Quant is the industry’s most precise and reproducible1 SPECT/CT quantitative solution. Available for 99mTc, 123I, 177Lu, 111In, and 131I imaging,2 xSPECT Quant enables clinical SPECT/CT quantification to more precisely detect disease and better manage therapy.

The absolute quantification capabilities of xSPECT Quant are also a basis for theranostics, the unique approach of combining diagnostics and therapy.

What experts say

“Quantitative images are part of almost every study we do. This allows us to obtain more precise information for each patient. With quantitative data, we are starting to detect abnormalities earlier and tailor treatments.”

xSPECT Quant 131I is not commercially available in all countries. Due to regulatory reasons, its future availability cannot be guaranteed. Please contact your local Siemens organization for further details.
The statements by Siemens Healthineers' customers described herein are based on results that were achieved in the customer's unique setting. Since there is no "typical" hospital and many variables exist (e.g., hospital size, case mix, level of IT adoption) there can be no guarantee that other customers will achieve the same results.
