Commentary

Until the twentieth century, cerebral abnormalities were diagnosed through careful history collection and a comprehensive clinical examination. Anatomic imaging of the brain became possible with the discovery of X-rays and, later, with the introduction of computed tomography in the early 1970s [1]. As a result, our capacity to detect cerebral abnormalities in patients has improved, making neuroimaging a game-changing diagnostic tool.

Stroke and seizures are the most common neurological emergencies, accounting for over half of all emergency room neurology consultations. The most common neurological emergencies are strokes and seizures, which account for more than half of all emergency room neurology visits. The majority of stroke diagnoses are made clinically; however, imaging can help distinguish between ischemia, bleeding, and stroke mimics [2]. In the latter case, seizure is frequently discovered to be a stroke mimic in daily practice. The use of various techniques to either directly or indirectly visualise the structure, function, or pharmacology of the nervous system is known as neuroimaging or brain imaging. CT, MRI, and PET guided stereotactic surgery or radiosurgery for the treatment of brain tumours, arteriovenous malformations, and other surgically curable diseases is another reason for neuroimaging. Within medicine, neurology, and psychology, it is a relatively recent discipline. “Neuroradiologists” are doctors who specialise in performing and interpreting neuroimaging in a clinical context. The field of neuroimaging is concerned with the in vivo representation of the structure and function of the Central Nervous System (CNS) in both health and disease [3]. Although neuroimaging was once thought to be the realm of radiologists with a special interest in the nervous system, participants in this quickly developing discipline now come from a wide range of backgrounds. It's vital to keep in mind that neuroimaging is a constantly changing discipline. The field of neuroimaging had progressed to the point that limited practical applications of functional brain imaging were possible in the early 2000s. The most common application area is primitive brain-computer interfaces [4].

The 'human circulation balance, established by Italian neuroscientist Angelo Mosso, could non-invasively assess the redistribution of blood during emotional and intellectual activity, is the first chapter in the history of neuroimaging. After a neurological evaluation, a physician may order neuroimaging to further study a patient who has or may have a neurological condition. Simple syncope is one of the most common neurological issues that people face. Neuroimaging is not recommended for people who have migraine headaches that are stable. According to studies, the presence of migraine does not raise the risk of cerebral disease in patients [5].

Neuroimaging is divided into two categories:

• Structural imaging examines the nervous system's structure and aids in the identification of extensive (large-scale) intracranial disease (such as a tumour) and injury

• Functional imaging is a type of imaging that can be used to diagnose metabolic disorders and lesions on a smaller scale (such as Alzheimer's disease) as well as for neurological and cognitive psychology research

Neuroimaging includes some basics techniques. They are:

• Computed axial tomography

• Diffuse optical imaging

• Event-related optical signal

• Magnetic resonance imaging

• Functional magnetic resonance imaging

• Magnetoencephalography

• Positron emission tomography

• Single-photon emission computed tomography

• Cranial ultrasound

• Functional ultrasound imaging
