BACKGROUND Although quantitative analysis using standardized uptake value (SUV) becomes realistic in clinical single-photon emission computed tomography/computed tomography (SPECT/CT) imaging, reconstruction parameter settings can deliver different quantitative results among different SPECT/CT systems. This study aims to propose a use of the digital reference object (DRO), which is a National E...
We present a fast, validated, open-source toolkit for processing dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) data. We validate it against the Quantitative Imaging Biomarkers Alliance (QIBA) Standard and Extended Tofts-Kety phantoms and find near perfect recovery in the absence of noise, with an estimated 10-20× speedup in run time compared to existing tools. To explain the ob...
Background Quantitative MR relaxometry techniques are increasingly used in cardiac MR applications, e.g. MOLLI for high resolution T1 mapping. To use these techniques in the clinic, we must understand how to make comparable measurements across vendor systems and software versions and compare results across sites. A standardized phantom used for regular quality control is one approach. The Bioma...
