Background: There is limited but growing research regarding the accuracy of CTP in diagnosing acute posterior ischemia stroke. We sought to evaluate the diagnostic accuracy of an incremental multimodal CT protocol in acute posterior ischemic stroke. Methods: Retrospective review of incremental NCCT, CTA-source images and CTP use in 82 consecutive patients with acute posterior ischemic stroke. R...

Multi-modality imaging provides coregistered PET-CT and SPECT-CT images; however such multi-modality workflows usually consist of sequential scans from the individual imaging components for each modality. This typical workflow may result in long scan times limiting throughput of the imaging system. Conversely, acquiring multi-modality data simultaneously may improve correlation and registration...

Lymphoscintigraphy is a nuclear medicine procedure that is used to detect sentinel lymph nodes (SLNs). This project sought to investigate fusion of planar scintigrams with CT topograms as a means of improving the anatomic reference for the SLN localization. Heretofore, the most common lymphoscintigraphy localization method has been backlighting with a (57)Co sheet source. Currently, the most pr...

Abstract We assessed the accuracy of deformable image registration (DIR) between CT and MR images using an open-source software (Elastix, from Utrecht Medical Center) a commercial (Velocity AI Ver. 3.2.0 Varian Systems, Palo Alto, CA, USA) software. Five male patients’ pelvic regions were studied publicly available CT, T1-weighted (T1w) MR, T2-weighted (T2w) images. In cost function Elastix, we...
