Neuroimaging for Early Diagnosis of Alzheimer's Disease: a Review.

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disease that primarily affects people above the age of 60 all around the world. As of now, the cause is unknown and there is no effective cure. The pathological changes of AD have occurred many years before the onset of the disease, and current treatment techniques can only delay the progression of the disease.

Grey matter alterations in generalized anxiety disorder: A voxel-wise meta-analysis of voxel-based morphometry studies.

Objective: Grey matter, a crucial component of the brain, has been found altered in generalized anxiety disorder (GAD) of several voxel-based morphometry studies. The conclusive and consistent grey matter alterations in GAD have not been confirmed.

Method: Eleven voxel-based morphometry studies of GAD patients were included in the current systematic review and meta-analysis.

Monorail snare technique for retrieval of stretched coil.

Coil stretching is a recognized complication during cerebral aneurysm embolization. For over a decade, the microsnare has proven effective in retrieving migrated coils. Fiorella et al.

Coil embolization of distal vascular lesion using a 1.5 Fr Marathon microcatheter and 'free-running' technique.

In distal vascular lesions, such as the distal anterior inferior cerebellar artery or posterior inferior cerebellar artery (PICA) dissecting aneurysm, and dural arteriovenous fistula (dAVF) and arteriovenous malformation (AVM), super-selective catheterization and embolization using liquid agents, such as NBCA or Onyx liquid embolic system, is the preferred treatment.1 2 We used a flow-directed 1.5 Fr Marathon microcatheter (Medtronic, Minneapolis, MN, USA) for embolization because commonly used detachable coil-compatible microcatheters can be too short or rigid for superselection.

A deep learning-based method for the diagnosis of vertebral fractures on spine MRI: retrospective training and validation of ResNet.

Purpose: To improve the performance of less experienced clinicians in the diagnosis of benign and malignant spinal fracture on MRI, we applied the ResNet50 algorithm to develop a decision support system.

Methods: A total of 190 patients, 50 with malignant and 140 with benign fractures, were studied. The visual diagnosis was made by one senior MSK radiologist, one fourth-year resident, and one first-year resident.

Lhermitte-Duclos disease: A case report with radiologic-pathologic correlation.

Lhermitte-Duclos disease (LDD) stems from the development of a rare benign lesion of uncertain pathogenesis that distorts the normal cerebellar laminar cytoarchitecture. We explored the lesion's appearance on conventional magnetic resonance imaging (MRI) combined with susceptibility-weighted imaging, diffusion-weighted imaging, perfusion imaging, or arterial spin labeling. Although many cases of LDD have been previously reported in the literature, the radiologic-pathologic correlation has been described in only a few of these cases.
