Abstract This study presents a workflow for identifying and characterizing patients with Heart Failure (HF) multimorbidity utilizing data from Electronic Health Records. Multimorbidity, the co-occurrence of two or more chronic conditions, poses significant challenge on healthcare systems. Nonetheless, understanding multimorbidity, including most common disease interactions, risk factors, treatment responses, remains limited, particularly complex heterogeneous conditions like HF. We conducted...
Phenotyping, the process of systematically identifying and classifying conditions within clinical data, is a crucial first step in any data science work involving Electronic Health Records (EHRs). Traditional approaches require extensive manual annotation efforts face challenges with scalability. We investigated use Large Language Models (LLMs) for zero-shot phenotyping 20 prevalent chronic based on synthetic patient summaries generated from real structured EHRs codes. evaluated performance...
A doença falciforme é um grupo de doenças hereditárias, decorrente da mutação monogênica, na cadeia ß-globínica hemoglobina. Atualmente, o tratamento não farmacológico proposto constituído suplementos aminoácidos por via oral ou intravenosa. Objetivo: avaliar os efeitos suplementação com arginina em portadores falciforme, diferentes faixas etárias. Metodologia: revisão narrativa busca artigos nas bases dados Pubmed, Scopus, Scielo e Lilacs, publicações dos últimos 11 anos, sendo excluídos...
In order to benefit from the increased spectral bandwidth at ultrahigh field (UHF), use of parallel transmission (pTx) mitigate flip-angle inhomogeneity in chemical exchange saturation transfer (CEST) imaging is investigated.A pTx basis pulse homogenised by magnitude least-squares (MLS) optimization and expanded form a frequency-selective for CEST. The was simulated with three-pool Bloch-McConnell equation evaluate impact on CEST contrast. vivo performance (7 T) standard Gaussian circularly...
To develop an open-source prototype of myocardial T1 mapping (Open-MOLLI) to improve accessibility cardiac and evaluate its repeatability. With Open-MOLLI, we aim enable faster implementation testing sequence modifications facilitate inter-scanner cross-vendor reproducibility studies.
Building on the success of positron emission tomography (PET)/CT scanners, a hybrid imaging technology, combining PET with versatile attributes magnetic resonance (MRI), has been in use for over ten years. At Forschungszentrum Jülich, one four prototypes available worldwide, commercial 3T MRI newly developed BrainPET insert, was installed 2008, allowing simultaneous data acquisition and MRI. Here, we report our ten-year-long experience methods technology through this paper numerous patients...
The deployment of offshore wind parks face several challenges. Among them are the difficulties introduced by atmospheric and sea conditions in accessing those parks. A window opportunity is a timeframe when weather acceptable enable to perform specific tasks installation operation/maintenance park. This study identifies typical time periods windows access three Portuguese maritime regions. accessibility also take into account system type transportation method for local access, namely, rubber...
Microwave imaging (MWI) has been studied as a complementary modality to improve sensitivity and specificity of diagnosis axillary lymph nodes (ALNs), which can be metastasized by breast cancer. The feasibility such system is based on the dielectric contrast between healthy ALNs. However, reliable information anatomically realistic numerical models matching properties region ALNs, are crucial develop MWI systems, still limited in literature. purpose this work methodology infer structures from...
The consensus for the clinical implementation of arterial spin labeling (ASL) perfusion imaging recommends a segmented 3D Gradient and Spin-Echo (GRASE) readout optimal signal-to-noise-ratio(SNR). correction associated susceptibility-induced geometric distortions has been shown to improve diagnostic precision, but its impact on ASL data not systematically assessed it is consistently part pre-processing pipelines. Here, we investigate effects distortion by pseudo-continuous (pCASL) with GRASE...
Abstract Advanced perfusion‐weighted imaging (PWI) methods that combine gradient echo (GE) and spin (SE) data are important tools for the study of brain tumours. In PWI, single‐shot, EPI‐based have been widely used due to their relatively high speed. However, when with increasing spatial resolution, single‐shot EPI often show limitations in whole‐brain coverage multi‐contrast applications. To overcome this limitation, work employs a new version keyhole (EPIK) provide five echoes: two GEs,...
Background Echo planar imaging (EPI) is one of the methods choice in dynamic susceptibility contrast MRI (DSC‐MRI) because it provides a sufficient temporal resolution. However, relatively long readout duration EPI often imposes limitations on increased spatial coverage or use multiple contrasts. Purpose To develop DSC‐MRI method using EPIK (EPI with keyhole) to provide dual‐contrast (TE 1 and TE 2 ) information higher than EPI. compare results from community‐standard proposed method. Study...
The Multimodal Imaging Brain Connectivity Analysis (MIBCA) toolbox is a fully automated all-in-one connectivity analysis that offers both pre-processing, connectivity, and graph theory of multimodal images such as anatomical, diffusion, functional MRI, PET. In this work, the MIBCA functionalities were used to study Alzheimer's Disease (AD) in MR/PET approach. Materials Methods: Data from 12 healthy controls, 36 patients with EMCI, LMCI AD (12 for each group) obtained Neuroimaging Initiative...
