Article Synopsis
- A meta-analysis was conducted to compare lesion detection rates in Multiple Sclerosis between Double Inversion Recovery (DIR) and T2-FLAIR imaging techniques, focusing on 3D acquisition methods.
- Data was gathered from multiple medical databases, assessing various studies that met strict inclusion criteria to ensure relevance and accuracy.
- The analysis revealed that DIR significantly outperformed T2-FLAIR in detecting intracortical and infratentorial lesions, while results for total cortical lesions did not show significant differences between the two methods.
Article Synopsis
- Secondary amenorrhea is defined as the absence of menstrual cycles for over 3 months in women with previously regular periods, or over 6 months in those with irregular cycles, requiring lab tests to check for pituitary function.
- A case study of a 31-year-old woman with Diamond-Blackfan anemia and type 2 diabetes showed she experienced amenorrhea for a year after IUD removal, leading to lab tests revealing low levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH).
- An MRI of her pituitary gland showed no signal, indicating pituitary dysfunction likely caused by iron overload from her frequent blood transfusions, resulting in her treatment with an iron chelator and oral contraception.
Transcranial focused ultrasound (FUS) is a versatile, MR-guided, incisionless intervention with diagnostic and therapeutic applications for neurologic and psychiatric diseases. It is currently FDA-approved as a thermoablative treatment of essential tremor and Parkinson disease. However, other applications of FUS including BBB opening for diagnostic and therapeutic applications, sonodynamic therapy, histotripsy, and low-intensity focused ultrasound neuromodulation are all in clinical trials.

Background: Myelin oligodendrocyte glycoprotein antibody associated disease (MOGAD) is a relatively new disease entity in the field of demyelinating disorders. Its first diagnostic criteria have recently been published.
Objectives: We evaluated the positive predictive value (PPV) for MOG-IgG testing and report the clinical and radiologic features with respect to the recently published criteria.
Magnetoencephalography (MEG) is a noninvasive neuroimaging technique widely recognized for epilepsy and tumor mapping. MEG clinical reporting requires a multidisciplinary team, including expert input regarding each dipole's anatomic localization. Here, we introduce a novel tool, the "Magnetoencephalography Atlas Viewer" (MAV), which streamlines this anatomical analysis.
