Generation of high-resolution MPRAGE-like images from 3D head MRI localizer (AutoAlign Head) images using a deep learning-based model.

Purpose: Magnetization prepared rapid gradient echo (MPRAGE) is a useful three-dimensional (3D) T1-weighted sequence, but is not a priority in routine brain examinations. We hypothesized that converting 3D MRI localizer (AutoAlign Head) images to MPRAGE-like images with deep learning (DL) would be beneficial for diagnosing and researching dementia and neurodegenerative diseases. We aimed to establish and evaluate a DL-based model for generating MPRAGE-like images from MRI localizers.

Handgrip strength in patients with type 2 diabetes correlates with diabetic polyneuropathy. A single-center, retrospective observational study in Japanese patients.

Nerve conduction studies (NCS) are the standard method for diagnosing diabetic polyneuropathy. Because a clear association between handgrip strength and diabetic neuropathy can serve as a screening tool, the present study evaluated the association between handgrip strength and NCS and diabetes-related complications. A total of 436 patients with type 2 diabetes (T2D) who were admitted to our hospital between April 1, 2018 and March 31, 2023, and evaluated using Baba's diabetic neuropathy classification (BDC) were included.

Clinical outcomes of endocrine and other disorders induced by immune checkpoint inhibitors in Japanese patients.

The purpose of this study was to analyze the efficacy of treatment and survival after administration of immune checkpoint inhibitor (ICI) in Japanese patients and had endocrine-related and/or other immune-related adverse events (irAEs), as well as irAEs in multiple organs. This is a single-center, retrospective, observational study of 571 Japanese patients treated with ICI at our hospital. We evaluated the occurrence of Grade 3 or higher irAEs and the life expectancy and treatment efficacy after ICI administration.

Comparison of DWI techniques in patients with epidermoid cyst: TGSE-BLADE DWI vs. SS-EPI DWI.

Purpose: To compare quantitative values and image quality between single-shot echo-planar imaging (SS-EPI) diffusion-weighted imaging (DWI) and two-dimensional turbo gradient- and spin-echo DWI with non-Cartesian BLADE trajectory (TGSE-BLADE DWI) in patients with epidermoid cyst.

Methods: Patients with epidermoid cyst who underwent both SS-EPI DWI and TGSE-BLADE DWI were included in this study. Two raters placed ROIs encircling the entire epidermoid cyst on SS-EPI DWI, and then on TGSE-BLADE DWI.

Early radiological reduction of periventricular anastomosis after direct bypass surgery for adult moyamoya disease.

Objective: Periventricular anastomosis (PA), a recently recognized cause of hemorrhage in moyamoya disease, is reducible after bypass surgery. The timing of the reduction, however, remains poorly understood. The objectives of the present study were to demonstrate radiological reduction of PA occurring within 48 hours after surgery and to identify factors associated with reduction.
