A Meta-analysis of 68Ga-FAPI PET in Assessment of Ovarian Cancer.
Acad Radiol
March 2025
Department of Nuclear Medicine, Beijing Luhe Hospital, Capital Medical University, Xinhua Road 82, Tong Zhou District, 101199 Beijing, China.
Rationale And Objectives: The objective of this research is to carry out a systematic review and meta-analysis to detect the diagnostic efficacy of 68Ga-FAPI Positron Emission Tomography (PET) Computed Tomography/Magnetic Resonance (CT/MR) in total of the lesions as well as different aspects of metastasis in individuals with ovarian cancers (OC).
Materials And Methods: The PubMed, Embase, Cochrane library, and Web of Science databases were thoroughly searched until the cut-off date of July 23, 2024. The assessment of 68Ga-FAPI PET CT/MR of OC was presented by the included studies.
Best Practices for Imaging of Transcatheter Valve Failure: An Update From the Heart Valve Collaboratory.
J Am Coll Cardiol
March 2025
Cedars Sinai Medical Center, Los Angeles, California, USA. Electronic address:
This updated Heart Valve Collaboratory framework addresses the growing concern for transcatheter valve failure (TVF) following transcatheter aortic valve replacement (TAVR). With the increasing volume of redo-TAV and surgical TAV explantation, there is a critical need for standardized pathways and protocols for evaluating TVF using echocardiography and cardiac computed tomography (CT) angiography. This document clarifies prior definitions of bioprosthetic valve deterioration and bioprosthetic valve failure in a practical, imaging directed context for TAVR.

Department of Ophthalmology, University of Pittsburgh School of Medicine, Pittsburgh, PA, United States. Electronic address:
A defining characteristic of the human brain is that, notwithstanding the clear anatomic similarities, the two cerebral hemispheres have several different functional superiorities. The focus of this chapter is on the hemispheric asymmetry associated with the function of face identity processing, a finely tuned and expert behavior for almost all humans that is acquired incidentally from birth and continues to be refined through early adulthood. The first section lays out the well-accepted doctrine that face perception is a product of the right hemisphere, a finding based on longstanding behavioral data from healthy adult human observers.

Radiation Detection and Medical Imaging, Delft University of Technology Faculty of Applied Sciences, Mekelweg 15, 2629JB Delft, THE NETHERLANDS, Delft, 2628 CJ, NETHERLANDS.
Objective: Utilizing prompt gammas in preclinical pinhole-collimated PET avoids image degradation due to positron range blurring and photon down scatter, enables multi-isotope PET and can improve counting statistics for low-abundance positron emitters. This was earlier reported for 124I, 89Zr and simultaneous 124I -18F PET using the VECTor scanner (MILabs, The Netherlands), demonstrating sub-mm resolution despite long positron ranges. The aim of the present study is to investigate if such sub-mm PET imaging is also feasible for a large variety of other isotopes including those with extremely high energy prompt gammas (>1 MeV) or with complex emission spectra of prompt gammas.
