Assessing Lumbar Plexus and Sciatic Nerve Damage in Relapsing-Remitting Multiple Sclerosis Using Magnetisation Transfer Ratio

Frontiers in Neurology, 2021
Background: Multiple sclerosis (MS) has traditionally been regarded as a disease confined to the central nervous system (CNS). However, neuropathological, electrophysiological, and imaging studies have demonstrated that the peripheral nervous system (PNS)

Multimodality imaging of cor triatriatum dexter complicated with hypertrophic cardiomyopathy of restrictive phenotype

Radiology Case Reports, 2022
Cor triatriatum dexter (CTD) is an extremely rare congenital cardiac malformation in which a membrane divides the right atrium into 2 chambers. Hypertrophic cardiomyopathy (HCM) with restrictive phenotype is also a rare cardiomyopathy.
