Altered Resting-State Amygdalar Functional Connectivity in Primary Angle-Closure Glaucoma Patients
CONCLUSIONS: Patients with PACG exhibit extensive resting state abnormalities with respect to the FC between the amygdala and other regions of the brain, suggesting that dysregulated amygdalar FC may play a role in the pathophysiology of PACG.PMID:38682218 | DOI:10.31083/j.jin2304075 (Source: Journal of Integrative Neuroscience)

Microvascular Perfusion Imaging in Alzheimer's Disease
J Integr Neurosci. 2024 Apr 1;23(4):70. doi: 10.31083/j.jin2304070.ABSTRACTAlzheimer's disease (AD) is the leading cause of dementia worldwide and significantly impacts the essential functions of daily life and social activities. Research on AD has found that its pathogenesis is related to the extracellular accumulation of amyloid-beta (Aβ) plaques and intracellular neurofibrillary tangles in the cortical and limbic areas of the human brain, as well as cerebrovascular factors. The detection of Aβ or tau can be performed using various probes and methodologies. However, these modalities are expensive to implement and often...

Two-headed UNetEfficientNets for parallel execution of segmentation and classification of brain tumors: incorporating postprocessing techniques with connected component labelling
ConclusionOur study demonstrates the high efficiency and accuracy of the proposed UNetEfficientNet-B4 model in the automatic and parallel detection and segmentation of brain tumors from MRI images. This approach holds promise for improving diagnosis and treatment planning for patients with brain tumors, potentially leading to better outcomes and prognosis.

Combined lie ’s type D and type a agenesis of the left internal carotid artery diagnosed by magnetic resonance angiography
ConclusionLie ’s type D ICA agenesis usually does not communicate with the anterior and posterior circulations. We encountered a case of combined type D and type A ICA agenesis. To our knowledge, no similar case has been reported in the English literature. This is the second case of type D ICA agenesis with pat ent ipsilateral PCoA. We speculate that in case of type A ICA agenesis, when the development of the PCoA is insufficient to support collateral blood flow, an anastomotic vessel between bilateral ICAs may develop.

Treatment Monitoring in Multiple Sclerosis — Efficacy and Safety
Magnetic resonance imaging is the most sensitive method for detecting inflammatory activity in multiple sclerosis, particularly in the brain where it reveals subclinical inflammation. Established MRI markers include contrast-enhancing lesions and active T2 lesions. Recent promising markers like slowly expanding lesions and phase rim lesions are being explored for monitoring chronic inflammation, but require further validation for clinical use. Volumetric and quantitative MRI techniques are currently limited to clinical trials and are not yet recommended for routine clinical use. Additionally, MRI is crucial for detecting c...

MR Imaging of the Fetal Genitourinary Tract
Fetal MR imaging overcomes many of the technical barriers of ultrasound and is an important diagnostic tool for fetal genitourinary (GU) anomalies. It is suited for evaluation of GU anomalies because of the fluid-sensitive sequences and superior soft tissue contrast. Often GU malformations are part of a multisystem genetic or congenital condition, and imaging the entire fetus with MR adds additional clarity about the extent of disease. It adds confidence to diagnoses of renal agenesis, urinary tract dilation, cystic disease, and tumors. It is particularly useful to delineate anatomy in complex GU malformations. This additi...

Cost of upper tract imaging obtained during hematuria evaluation: Analysis of a national claims database
CONCLUSIONS: In this nationally representative analysis, hematuria evaluation confers a significant cost burden, while the primary factor associated with higher costs of screening was imaging type. Based upon reduced cost of US-based strategies, further investigation should delineate its cost-effectiveness in the diagnosis of urological disease.PMID:38679529 | DOI:10.1016/j.urolonc.2024.03.008 (Source: Urologic Oncology)
