FDA Clears Software That Combines MRI Enhancement of PET Imaging with Automated Quantification of Amyloid and Tau PET

Incorporating structural MRI to improve PET imaging resolution, the MICSI-PET software also offers automated Centiloid quantification from amyloid PET scans.

The Food and Drug Administration (FDA) has granted 510(k) clearance for the MICSI-PET software, which reportedly facilitates enhanced image quality and provides automated quantification for tau and amyloid positron emission tomography (PET) scans.

Microstructure Imaging (MICSI), the developer of MICSI-PET, said the software offers the following key attributes:

• incorporation of structural MRI to enable denoising of PET images and improved image quality;

• automated Centiloid quantification for amyloid PET;

• automated CenTauR quantification for tau PET; and

• comparison of regional SUVr measurements and z-scores with normative controls.

“The difference can be dramatic in borderline amyloid cases,” noted Lawrence N. Tanenbaum, MD, FACR, a neuroradiologist and imaging technology advisor. “When you’re trying to determine whether there is true cortical sparing, MICSI-PET can make the pattern substantially easier to see. Adding automated quantification to that improved visualization gives the reader a much more powerful way to evaluate the examination.”
