In this issue of Neuroimaging Clinics, guest editor Dr. Tchoyoson Lim Choie Cheio brings his considerable expertise to the topic of Central Nervous System Infections. Infections can involve any part of the CNS and often, multiple parts of the CNS are involved at the same time. The imaging surrounding them is constantly evolving, and in this issue, key international experts provide a thorough update of the imaging of these common and pervasive infections. Contains 13 practice-oriented topics including emerging public health, multidisciplinary teams and pitfalls in CNS infection imaging; acute neurological complications of COVID-19; subacute to chronic neuroimaging findings in SARS-CoV-2/COVID-19 infection; imaging of opportunistic infections and HIV/AIDS; imaging of head and neck infections; and more. Provides in-depth clinical reviews on central nervous system infections, offering actionable insights for clinical practice. Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.

CT, contrast CT, MRI, functional MRI, SPECT, CTA, and x-ray as tools to identify pathogens and diagnose intracranial infections are presented. Topics include: Epidemiology of Central Nervous System Infections; Imaging of Cranial Meningitis and Ventriculitis; Encephalitis, Cerebritis and Brain Abscess; Imaging of Central Nervous System Tuberculosis; Imaging of Rickettsial, Spirochetal, and Parasitic Infections; Imaging of Neurocysticercosis; Fungal Infections of the Central Nervous System; Central Nervous System Infections in the Pediatric Population; Imaging of Infectious Diseases of Spine; Neuropathological Findings in Intracranial Infections; Neurosurgical Approach to Infectious Disease of the Brain; Head and Neck Infections.

Most central nervous system diseases that lead to severe neurologic dysfunction or death are caused by viruses and abnormally configured proteins called prions. This new issue of Neuroimaging Clinics, Guest Edited by Turgut Tali, explores the imaging used to detect these diseases. Articles cover topics on Neuropathology of Virus Infections of the CNS, Imaging of "slow viruses" Infections of the CNS, Imaging of Post-infectious Encephalomyelitis, and Imaging of HSV Infections of the CNS.

Spinal Infections is explored in this important Neuroimaging Clinics issue. Articles include: Pathologic approach to spinal cord infections; Pediatric spinal infection and inflammation; Pediatric and adult spinal Tb: imaging and pathophysiology; Pyogenic spinal infections; Spinal brucellosis; Viral infection of the spinal cord and roots; Parasitic and rare spinal infections; Overview of complications and sequeala in spinal infections; Neurosurgical approach to spinal infections; Image guided interventions in spinal infections; Pathological basis of pyogenic, nonpyogenic, and other spondylitis and discitis, and more!

Diseases once believed to be confined to the tropics, such as parasitic, mycobacterial, fungal, bacterial, and viral infections are still a major cause of mortality and moribidity in the tropics, yet can affect the developed world in an era of increased global travel and migration. Neuroimaging technique developments over the last several decades have helped clinicians better understand and diagnose these conditions. Experts from tropical countries share their experiences regarding tropical disorders, some of which are rare in the western world, but possible to appear in patients and not readily recognized by specialists not familiar with these diseases. Topics in this issue include: Relevance of neuroimaging in the diagnosis and management of tropical neurologic disorders; Pathology of Tropical Diseases; Viral Infections of the Central Nervous System; Central Nervous System Tuberculosis; Parasitic diseases of nervous system; Neuroimaging in Post-infectious Demyelination and Nutritional Disorders of the Central Nervous System; CNS Fungal Infections in the Tropics; Neuroimaging Epilepsy in the Tropics; Neuroimaging in Cranio-Vertebral Anomalies as seen in Tropics; Vascular Brain Pathologies; Neurobrucellosis; Hirayama Disease; Transverse Myelitis; and Pyomyositis.

This issue of Critical Care Nursing Clinics is Guest Edited by Cynthia Bautista, PhD, RN, CNRN and will focus on Central Nervous System Infections. Article topics will include bacterial meningitis, viral meningitis, viral encephalitis, cerebral abscess, spinal abscess, and ventriculitis.
