SynthPET: A 3D generative AI approach for FDG-PET image synthesis from T1-weighted MRI and ASL CBF in Alzheimer's disease. [PDF]

Alzheimers Dement
Abstract INTRODUCTION Fluorodeoxyglucose (FDG) positron emission tomography (PET) is widely used for detecting metabolic changes associated with neurodegeneration in Alzheimer's disease (AD) and other dementias but is costly and involves ionizing radiation. Here we developed SynthPET, a multimodal deep learning framework that synthesizes FDG PET images

ASL( Arterial Spin Labeling) perfuzija

Radiološke tehnologije, 2023
SAŽETAK Perfuzija se odnosi na isporuku kiseonika i hranljive materije u tkiva putem protok krvi i jedan je od najosnovnijih fiziološki parametri. Poremećaji perfuzije takođe čine većinu vodeći uzroci medicinskog invaliditeta i mortalitet.

A potential new role for ASL perfusion imaging: Diagnosis of metronidazole induced encephalopathy – Two companion cases

Radiology Case Reports, 2020
Metronidazole induced encephalopathy (MIE) is a rare condition due to prolonged high dose administration of metronidazole. MIE with corresponding increased perfusion on MRI arterial spin labeling (ASL) of the involved regions of the brain appears not to ...

Perfusion magnetic resonance imaging provides additional information as compared to anatomical imaging for decision-making in vestibular schwannoma

European Journal of Radiology Open, 2016
Objective: The added value of perfusion MRI for decision-making in vestibular schwannoma (VS) patients is unknown. MRI offers two perfusion methods: the first employing contrast agent (dynamic susceptibility contrast (DSC)-MRI) that provides information ...

Evaluation of cerebral blood flow in older patients with status epilepticus using arterial spin labeling

eNeurologicalSci, 2019
Introduction: Although older patients with status epilepticus (SE) have a high mortality rate and poor outcome, it is difficult to perform emergent electroencephalography (EEG) to diagnose SE in community hospitals.

Multiphase arterial spin labeling imaging to predict early recurrent ischemic lesion in acute ischemic stroke

Scientific Reports, 2022
In acute ischemic stroke (AIS), the hemodynamics around the lesion are important because they determine the recurrence or prognosis of the disease. This study evaluated the effects of perfusion deficits in multiphase arterial spin labeling (ASL) and ...

Arterial spin labeling assessment of myometrial perfusion changes in patients with uterine fibroid and its impact on fertility

The Egyptian Journal of Radiology and Nuclear Medicine, 2021
Background Fibroids are the most common uterine tumor in the reproductive age group. These tumors although benign, their relation to infertility is still controversial. The purpose of this study is to assess the fibroid impact on fertility using arterial
