A high-resolution MRI epilepsy protocol is essential for the assessment of recently diagnosed, long-term, and medication-resistant epilepsy, as epilepsy imaging rapidly advances. A review of MRI findings across the spectrum of epilepsy and their clinical importance is presented. selleck kinase inhibitor Evaluating epilepsy prior to surgery is greatly improved through the use of multimodality imaging, especially for cases with no abnormalities apparent on MRI scans. Clinical phenomenology, video-EEG, positron emission tomography (PET), ictal subtraction single-photon emission computerized tomography (SPECT), magnetoencephalography (MEG), functional MRI, and advanced neuroimaging techniques such as MRI texture analysis and voxel-based morphometry, when correlated, improve the identification of subtle cortical lesions, including focal cortical dysplasias, thereby optimizing epilepsy localization and surgical candidate selection.
Neuroanatomic localization hinges on the neurologist's ability to interpret clinical history and seizure phenomenology, which they uniquely approach. A significant role of clinical context, when coupled with advanced neuroimaging, is to identify subtle MRI lesions and pinpoint the epileptogenic lesion when multiple lesions complicate the picture. Seizure freedom following epilepsy surgery is 25 times more likely in patients demonstrating lesions on MRI scans than in those lacking such findings.
By meticulously examining the clinical background and seizure characteristics, the neurologist plays a distinctive role in defining neuroanatomical localization. The clinical context, when combined with advanced neuroimaging techniques, plays a significant role in detecting subtle MRI lesions, especially when identifying the epileptogenic lesion amidst multiple lesions. Individuals with MRI-confirmed lesions experience a 25-fold increase in the likelihood of seizure freedom post-epilepsy surgery compared to those without demonstrable lesions.

This piece seeks to introduce the reader to the diverse range of nontraumatic central nervous system (CNS) hemorrhages and the multifaceted neuroimaging techniques employed in their diagnosis and management.
The 2019 Global Burden of Diseases, Injuries, and Risk Factors Study revealed that intraparenchymal hemorrhage is responsible for 28% of the total global stroke impact. In the United States, 13% of all strokes are categorized as hemorrhagic strokes. Intraparenchymal hemorrhage occurrences increase dramatically with advancing age; therefore, despite progress in controlling blood pressure via public health efforts, the incidence rate does not diminish alongside the aging demographics. In the longitudinal investigation of aging, the most recent, autopsy results showed intraparenchymal hemorrhage and cerebral amyloid angiopathy in a percentage of 30% to 35% of the patients.
For swift detection of central nervous system (CNS) hemorrhage, comprising intraparenchymal, intraventricular, and subarachnoid hemorrhage, a head CT or brain MRI scan is indispensable. Upon detection of hemorrhage in a screening neuroimaging study, the configuration of the blood within the image, when considered in conjunction with the patient's history and physical assessment, can influence subsequent neuroimaging, laboratory, and ancillary tests needed to understand the cause. Having ascertained the origin of the issue, the primary therapeutic aims are to limit the expansion of bleeding and to avoid subsequent complications, such as cytotoxic cerebral edema, brain compression, and obstructive hydrocephalus. Furthermore, the topic of nontraumatic spinal cord hemorrhage will also be examined in a concise manner.
The expedient identification of CNS hemorrhage, characterized by intraparenchymal, intraventricular, and subarachnoid hemorrhage, mandates the use of either head CT or brain MRI. Once a hemorrhage is seen in the screening neuroimaging scan, the blood's structure, together with the patient's history and physical examination, informs the choice of subsequent neuroimaging, laboratory, and ancillary procedures for assessing the cause. Following the identification of the causative agent, the central objectives of the treatment protocol center on mitigating the expansion of hemorrhage and preventing subsequent complications, including cytotoxic cerebral edema, brain compression, and obstructive hydrocephalus. Subsequently, a limited exploration of nontraumatic spinal cord hemorrhage will also be explored.

This article focuses on the imaging procedures used to evaluate patients presenting with signs of acute ischemic stroke.
The widespread adoption of mechanical thrombectomy in 2015 represented a turning point in acute stroke care, ushering in a new era. Following the 2017 and 2018 randomized, controlled trials, the stroke community experienced a significant advancement, broadening the eligibility for thrombectomy using imaging-based patient selection, resulting in a heightened utilization of perfusion imaging. Following several years of routine application, the ongoing debate regarding the timing for this additional imaging and its potential to cause unnecessary delays in the prompt management of stroke cases persists. For today's neurologists, a deep and comprehensive understanding of neuroimaging techniques, their applications, and the methods of interpretation are more crucial than ever.
CT-based imaging, its widespread availability, rapid imaging, and safety, makes it the primary imaging modality used in most centers for evaluating patients experiencing symptoms of acute stroke. For determining if IV thrombolysis is appropriate, a noncontrast head CT scan alone suffices. Large-vessel occlusion is reliably detectable using CT angiography, which proves highly sensitive in this regard. Advanced imaging, comprising multiphase CT angiography, CT perfusion, MRI, and MR perfusion, offers additional data that can help with therapeutic choices in specific clinical situations. All cases necessitate the urgent performance and interpretation of neuroimaging to enable the timely provision of reperfusion therapy.
Due to its prevalence, speed, and safety, CT-based imaging often constitutes the initial diagnostic procedure for evaluating patients with acute stroke symptoms in most healthcare facilities.
