Article Synopsis
- The study investigates how brain volume is affected in elderly individuals with varying levels of dysglycemia, particularly focusing on the prediabetic stage and its potential impact on brain health.
- It involved 2,144 participants with an average age of 69, categorized into groups based on their HbA1c levels, identifying those with normal glucose metabolism, prediabetes, undiagnosed diabetes, and known diabetes.
- Results indicated that participants with prediabetes, undiagnosed diabetes, and known diabetes had significantly lower total gray matter volume compared to those with normal glucose metabolism, suggesting that high blood sugar levels can harm brain integrity even before diabetes is officially diagnosed.
Purpose: The human primary auditory cortex is located in the Heschl's gyrus (HG). To assess the intrinsic MR property in the gray matter of the HG (GM-HG) with T1 and T2 values using a commercially available MR fingerprinting (MRF) technique.
Methods: The subjects were 10 healthy volunteers (with 20 HGs; mean age, 31.
Background: Synthetic magnetic resonance imaging (SyMRI) enables to reformat various images by adjusting the MR parameters.
Purpose: To investigate whether customization of the repetition time (TR), echo time (TE), and inversion time (TI) in SyMRI could improve the visualization of subthalamic nucleus (STN).
Material And Methods: We examined five healthy volunteers using both coronal SyMRI and quantitative susceptibility mapping (QSM), seven patients with Parkinson's disease (PD) using coronal SyMRI, and 15 patients with PD using coronal QSM.
Rationale And Objectives: We evaluated the availability of cytological diagnosis with outer cannula washing solution (C-OCWS) as a clinical diagnostic tool for computed tomography (CT)-guided needle biopsy.
Materials And Methods: We retrospectively assessed 109 consecutive patients (71 males, 38 females; median age 68 years), who underwent CT-guided needle biopsy. In all patients, the specimens sampled by the inner needle were used for histological diagnosis, and those taken from the outer cannula were rinsed with 0.
