Nuclear imaging for bone metastases in prostate cancer: The Emergence of Modern Techniques Using Novel Radiotracers

open access: yes, 2021
Accurate staging of prostate cancer (PCa) at initial diagnosis and at biochemical recurrence is important to determine prognosis and the optimal treatment strategy. To date, treatment of metastatic PCa has mostly been based on the results of conventional

Cerebral Amyloid Deposition With 18F‐Florbetapir PET Mediates Retinal Vascular Density and Cognitive Impairment in Alzheimer's Disease

open access: yesHuman Brain Mapping, Volume 46, Issue 11, 01 August 2025.
We investigated the relationship between cerebral amyloid‐β (Aβ) deposition and retinal vascular density (VD) in Alzheimer's disease and their impact on cognitive impairment, using Aβ PET and fundus photography. We found that VD has the potential to serve as a biomarker for cognitive impairment, with Aβ deposition mediating this association.

Impact of type 1 diabetes on binocular vision: Evidence from a comparative analysis

open access: yesAnnals of the New York Academy of Sciences, Volume 1549, Issue 1, Page 208-218, July 2025.
Individuals with type 1 diabetes (T1D) without retinopathy exhibit significant impairments in binocular vision, including reduced near point of convergence, fusional vergence, vergence facility, and AC/A ratio. The prevalence of non‐strabismic binocular vision disorders is higher in T1D, emphasizing the need for comprehensive optometric evaluations ...

Feasibility and quality of nonmydriatic fundus photography in children

open access: yes, 2011
Ocular funduscopic examination is difficult in young children and is rarely attempted by nonophthalmologists. Our objective was to determine the feasibility of reliably obtaining high-quality nonmydriatic fundus photographs in children.

Imaging ligands targeting glypican-3 receptor expression in hepatocellular carcinoma

open access: yes, 2022
Hepatocellular carcinoma (HCC) is the third leading cause of cancer mortality. Early detection of HCC is important since potentially curative therapies exist in the initial stages of HCC; no curative therapies exist for late-stage HCC.

Myocardial Blood Flow and the Retinal Microvasculature Across the Spectrum From Normal to Failing Hearts

open access: yesThe Journal of Clinical Hypertension, Volume 27, Issue 6, June 2025.
ABSTRACT Deficiency of the myocardial microcirculation plays a role in the pathogenesis of heart failure (HF). We aimed to investigate the association of myocardial blood flow (MBF) and the retinal microvasculature with left ventricular (LV) function and its potential mediators.

Retinal Oxygen Kinetics and Hemodynamics in Choroidal Melanoma After Iodine‐125 Plaque Radiotherapy Using a Novel Structural‐Functional Imaging Analysis System

open access: yesCancer Medicine, Volume 14, Issue 8, April 2025.
Our study used advanced multimodal imaging techniques to demonstrate significant damage to retinal oxygen metabolism, vascular structure, and retinal blood flow in CM patients after iodine‐125 plaque radiotherapy. These findings may provide new pathophysiological insights into hypoxia in solid tumors after radiotherapy.
