Parametric Features of Regional Cerebral Blood Flow in Venous Ischemic Stroke

Acta Biomedica Scientifica, 2019
The lecture is devoted to the peculiarities of changes in tissue and cell perfusion of the brain with a rare pathology – venous ischemic stroke. Venous stroke, being a “relatively unknown cerebrovascular disease”, occurs up to 5 % of all cases of stroke.

A task-specific deep-learning-based denoising approach for myocardial perfusion SPECT [PDF]

arXiv, 2023
Deep-learning (DL)-based methods have shown significant promise in denoising myocardial perfusion SPECT images acquired at low dose. For clinical application of these methods, evaluation on clinical tasks is crucial. Typically, these methods are designed to minimize some fidelity-based criterion between the predicted denoised image and some reference ...

Comprehensive clinical evaluation of novel 4DCT‐based lung function imaging methods

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Methods have been developed that apply image processing to 4DCTs to generate 4DCT‐ventilation/perfusion lung imaging. Traditional methods for 4DCT‐ventilation rely on Hounsfield‐Unit (HU) density‐change methods and suffer from poor numerical robustness while not providing 4DCT‐perfusion data.

A preliminary study on predictors of treatment response to repetitive transcranial magnetic stimulation in patients with treatment‐resistant depression in Japan

Neuropsychopharmacology Reports, Volume 42, Issue 4, Page 478-484, December 2022., 2022
Abstract Background Brain imaging studies have reported that the effect of repetitive transcranial magnetic stimulation (rTMS) is associated with the activities of the dorsolateral prefrontal cortex (DLPFC) and ventral medial prefrontal cortex (VMPFC). However, few studies have been conducted in Japanese patients. Aim We aimed to identify brain regions

Uncertainty Analysis in 3D SPECT Reconstruction based on Probabilistic Programming [PDF]

arXiv, 2020
Single Photon Emission Computed Tomography (SPECT) is one of the nuclear medicine imaging modalities used for functional analysis of animal and human organs. Gamma rays emitted from the scanned body are filtered with collimators and detected by the SPECT head that is composed of an array of gamma detectors. The conventional reconstruction algorithms do

A Novel Theranostic Strategy for Malignant Pulmonary Nodules by Targeted CECAM6 with 89Zr/131I‐Labeled Tinurilimab

Advanced Science, EarlyView.
This study investigates the integrated diagnostic and therapeutic strategy utilizing 89Zr/131I‐labeled tinurilimab for the management of malignant lung nodules, with a particular focus on lung adenocarcinoma (LUAD). CEACAM6, which is highly expressed in most LUAD patients, activates the Src/FAK signaling pathway, thereby promoting cell proliferation ...
