Mirada Medical PET/MRI Software is Highlighted in Multiple Research Studies

Mirada’s software PET/MRI is an alternative to hybrid scanners

June 13, 2013 — Mirada Medical collaborators presentnew positron emission tomography/magnetic resonance imaging (PET/MRI) research.

PET/MRI is a rapidly developing field and Mirada is working to provide the software tools to support the research and trials necessary to realize the potential of the new modality in molecular imaging. The software supports both the hardware hybrid scanners and provides validated deformable registration for software based PET/CT(computed tomorgraphy)/MRI.

David Townsend, professor and director of the A*STAR-NUS Clinical Imaging Research Centre (CIRC) in Singapore, recently presented a paper entitled “Initial results of the assessment of PET/MR compared to PET/CT for diagnosis and staging of malignant disease.” This work is a comparative analysis of the image quality and quantification accuracy of hardware PET/MRI and PET/CT, a highly relevant topic of current interest in the field. Advanced quantification features and accurate deformable registration in Mirada PET/MRI software allowed the quantification of regions-of-interest simultaneously in both the PET/MRI and PET/CT of the same patient.

Another quantification analysis is presented in the work of Dr.Thomas Klausen of Rigshospitalet, Denmark, entitled “Image distortions and bias from dental restorations in PET/CT- and PET/MR-imaging.” In this work, Mirada’s support for multiple studies and multiple sequences enabled the analysis of artifacts arising from dental fillings on image quality and quantification on hardware PET/MRI and PET/CT.

Mirada’s software PET/MRI is an alternative to hybrid scanners and is based on deformable registration between the PET/CT and MRI to perform the fusion. A high-quality registration is critical for effective fusion between PET/CT and MRI. Mirada’s deformable registration algorithm, is the subject of another paper by Dr. Martin Lodge of Johns Hopkins University entitled “Combined PET/CT/MRI of the pelvis using software registration.” This work investigates the accuracy of the deformable registration between the CT and MR in the pelvis.

Representative PET/CT images of 18F-FDS and 18F-FDG in inflamed mice. Mice were inoculated with dead K. pneumoniae (10^8 CFU/mL). Imaging was performed for days 1, 2, 3 and 4 using 18F-FDG and 18F-FDS. CT images showed clear inflammation on day 2 and day 3 with corresponding high 18F-FDG uptake on PET. No significant uptake of 18F-FDS was detected for any of those 4 days. Credit: J Li et al., University of Louisville School of Medicine, Louisville, Ky.

Longitudinal PET imaging with 18F-AV45. PET imaging shows the average 18F-AV45 uptake per animal group at 8 and 13 months of age. A significant interaction of genotype treatment was observed in the cortex (p = 0.0248), hippocampus (p = 0.0071) and thalamus (p = 0.0084), indicating reduced [18F]-AV45 uptake in BACE1 inhibited transgenic mice.
