Brain magnetic resonance imaging findings in Mitochondrial Neurogastrointestinal Encephalomyopathy (MNGIE): A case-based review.

Mitochondrial neurogastrointestinal encephalopathy (MNGIE) is a rare autosomal recessive disorder, manifesting with gastrointestinal dysmotility, cachexia, ptosis and peripheral neuropathy. Diffuse leukoencephalopathy in brain MRI is a hallmark of MNGIE. We report a case of a 21-year-old female with MNGIE, presenting with cachexia and chronic diarrhea.

Survival Outcome Prediction in Glioblastoma: Insights from MRI Radiomics.

Extracting multiregional radiomic features from multiparametric MRI for predicting pretreatment survival in isocitrate dehydrogenase (IDH) wild-type glioblastoma (GBM) patients is a promising approach. MRI data from 49 IDH wild-type glioblastoma patients pre-treatment were utilized. Diffusion and perfusion maps were generated, and tumor subregions segmented.

"Long-term MRI findings in Ankylosing spondylitis patients treated with TNF inhibitors for a decade".

Objective: This study aims to evaluate the active and chronic lesions in sacroiliac joints and lumbar spine over a decade of TNFi therapy in patients with AS.

Methods: The study enrolled patients with AS under treatment with a TNFi for over a decade. The patients underwent a new MRI scan of their lumbar spine and sacroiliac joint (SIJ).

The Role of Novel Imaging and Biofluid Biomarkers in Traumatic Axonal Injury: An Updated Review.

Traumatic brain injury (TBI) is a leading cause of disability worldwide. Traumatic axonal injury (TAI) is a subtype of TBI resulting from high-impact forces that cause shearing and/or stretching of the axonal fibers in white matter tracts. It is present in almost half of cases of severe TBI and frequently associated with poor functional outcomes.

Brain Perfusion Changes in a Patient with Facial Trauma.

A 69-year-old male was admitted to our hospital because of left facial trauma with bone fractures, including the maxillary sinus, zygomatic arch, and ethmoid and sphenoid bones. Brain computed tomography was unremarkable but regional cerebral blood flow with hexamethyl-propylene-amine oxime single-photon emission computed tomography (SPECT) showed hypoperfusion of the left hemisphere, which was reversible since a repeat SPECT 4 months later was substantially improved. Brain perfusion SPECT may provide information on cerebrovascular status in some cases of facial injury.
