Growth speed of large brain metastases between diagnostic and radiosurgical planning MRI and predictors of rapid tumor growth
ConclusionLarge brain metastases can grow considerably between the time of diagnosis and the time of fSRS treatment planning. We recommend the time between dMRI and fSRS treatment initiation be as short as possible. (Source: Japanese Journal of Radiology)

Opioids and Accelerated Brain Aging: The White Matter Matters
Opioids are most highly prescribed in older adults, and because of aging and multimorbidity, this demographic is also most likely to suffer adverse events from this drug class. The article by Warner et al1 reports on the cross-sectional associations between prescription opioid exposures in community-dwelling older adults (older than 65 years) and gray and white matter structure assessed by magnetic resonance imaging. The primary exposure was the duration of opioid availability with a secondary e xposure of total morphine milligram equivalents (MME). (Source: Mayo Clinic Proceedings)

Capillary Telangiectasia
A female in her late 40s presented for a second opinion regarding a pontine lesion concerning for a possible glial neoplasm that has been present for at least 10 years by imaging. Prior magnetic resonance imaging scans showed a solitary well-circumscribed T1-hypointense and subtle T2/T2-fluid-attenuated inversion recovery hyperintense lesion in the lower pons with homogenous gadolinium enhancement but no overt hemosiderin deposition on gradient echo sequence and no evidence of any other suspicious lesions in the brain or spinal cord.

Magnetic Resonance Imaging Marker for the Conversion from Idiopathic Late-onset Cerebellar Ataxia to Multiple System Atrophy
Background: Although some patients with idiopathic late-onset cerebellar ataxia (ILOCA) are eventually diagnosed with multiple system atrophy with cerebellar type (MSA-C) with disease progression, the markers for this conversion are still not elucidated yet. Therefore, we investigated the imaging marker to predict the conversion from ILOCA to MSA-C based on the baseline magnetic resonance imaging (MRI). (Source: Parkinsonism and Related Disorders)

Modulation of neural activity in response to dance training in Parkinson ’s: A case study
Background: Recent evidence suggests that long-term participation in dance could delay the progression of symptoms in people with mild Parkinson ’s, but little is known about the neurobiological mechanisms of dance in Parkinson’s. The present case study used functional magnetic resonance imaging (fMRI) to investigate potential neuroplastic effects of dance in a 69-year-old male with mild Parkinson’s attending weekly dance for Parkinson ’s classes over a period of 29 weeks.

Comparing brain activation in two subtypes of task-specific focal dystonia during dystonia-related and unrelated tasks: An fMRI study
Background: Task-specific focal dystonia [TSFD] is characterized by involuntary, localized muscle contractions during specific motor activities (e.g., writing in focal hand dystonia [FHD], speaking in laryngeal dystonia [LD]). It is unclear if a shared central mechanism contributes to different body regions being affected in TFSD subtypes. Previous work using task-based functional magnetic resonance imaging (fMRI) has indicated abnormal activation in body-region-specific sensorimotor networks separately in FHD and LD against controls [CTL].

A Case of Gallbladder Cancer with Trousseau Syndrome Successfully Treated Using Radical Resection
We describe the first case of a successfully treated gallbladder adenocarcinoma accompanied by Trousseau syndrome. A 66-year-old woman presented with right hemiplegia. Magnetic resonance imaging identified multiple cerebral infarctions. Her serum carbohydrate antigen 19-9 and D-dimer levels were markedly elevated, and a gallbladder tumor was detected via abdominal computed tomography. Venous ultrasonography of the lower limbs revealed a deep venous thrombus in the right peroneal vein. These findings suggested that the brain infarctions were likely caused by Trousseau syndrome associated with her gallbladder cancer. Radical...

An Optimization Numerical Spiking Neural Membrane System with Adaptive Multi-Mutation Operators for Brain Tumor Segmentation
Int J Neural Syst. 2024 Apr 30:2450036. doi: 10.1142/S0129065724500369. Online ahead of print.ABSTRACTMagnetic Resonance Imaging (MRI) is an important diagnostic technique for brain tumors due to its ability to generate images without tissue damage or skull artifacts. Therefore, MRI images are widely used to achieve the segmentation of brain tumors. This paper is the first attempt to discuss the use of optimization spiking neural P systems to improve the threshold segmentation of brain tumor images. To be specific, a threshold segmentation approach based on optimization numerical spiking neural P systems with adaptive mult...
