Journal Article Neuroimaging Clin N Am · May 2024 Acute stroke imaging plays a vital and time-sensitive role in therapeutic decision-making. Current clinical workflows widely use computed tomography (CT) and magnetic resonance (MR) techniques including CT and MR perfusion to estimate the volume of ischemi ... Full text Link to item Cite

Magnetic resonance imaging of pediatric liver tumors.

Journal Article Pediatr Radiol · February 2022 Liver tumors in children can be benign or malignant. Although several clinical factors are important in the evaluation of these lesions, MRI is particularly important for lesion characterization and tumor staging. In children, use of a hepatobiliary contra ... Full text Link to item Cite

Sincalide-Stimulated Cholescintigraphy: A Retrospective Study and Proposal of a Modified Workflow.

Journal Article Clin Nucl Med · January 1, 2022 PURPOSE: Current guidelines for sincalide-stimulated cholescintigraphy (SSC) call for a 60-minute sincalide infusion, and a gallbladder ejection fraction (GBEF) ≥38% is considered normal. In this retrospective study, we hypothesize that most patients reach ... Full text Link to item Cite

PET/CT Limitations and Pitfalls in Urogenital Cancers.

Journal Article Semin Nucl Med · November 2021 Hybrid FDG PET/CT plays a vital role in oncologic imaging and has been widely adopted for the staging and restaging of a variety of malignancies. Its diagnostic value in urogenital malignancies is less well-known, not at least because of the variable FDG a ... Full text Link to item Cite

Functional Connectivity of Resting Hemodynamic Signals in Submillimeter Orientation Columns of the Visual Cortex.

Journal Article Brain Connect · October 2016 Resting-state functional magnetic resonance imaging has been increasingly used for examining connectivity across brain regions. The spatial scale by which hemodynamic imaging can resolve functional connections at rest remains unknown. To examine this issue ... Full text Link to item Cite

Cognitive activity, cognitive function, and brain diffusion characteristics in old age.

Journal Article Brain Imaging Behav · June 2016 The objective of this work was to test the hypotheses that a) more frequent cognitive activity in late life is associated with higher brain diffusion anisotropy and lower trace of the diffusion tensor, and b) brain diffusion characteristics partially media ...
