Article Synopsis
  • - The study aimed to assess the optimization of common computed tomography (CT) procedures by measuring the volume computed tomography dose index (CTDIvol) and dose-length product (DLP) during various examinations.
  • - Results indicated that variations in CTDIvol and DLP were primarily due to differences in the techniques employed, with specific values established for different CT procedures across multiple hospitals.
  • - The findings, including key CTDIvol values (40.9, 9.0, 9.4, and 16.2 mGy) and corresponding DLP values (900, 360, 487, and 721 mGy.cm), provide a foundation for enhancing the optimization of CT procedures in the country.

Background: The brain volume loss also known as brain atrophy is increasingly observed among children in the course of performing neuroimaging using CT scan and MRI brains. While severe forms of brain volume loss are frequently associated with neurocognitive changes due to effects on thought processing speed, reasoning and memory of children that eventually alter their general personality, most clinicians embark themselves in managing the neurological manifestations of brain atrophy in childhood and less is known regarding the offending factors responsible for developing pre-senile brain atrophy. It was therefore the goal of this study to explore the factors that drive the occurrence of childhood brain volume under the guidance of brain CT scan quantitative evaluation.

Although it is a normal involution process in advanced age, brain atrophy-also termed atrophic encephalopathy-can also occur prematurely in childhood as a consequential effect of brain tissues injury through trauma or central nervous system infection, though in both normal and premature occurrences this condition always presents with loss of volume relative to the skull. A common tool for the functional study of brain activities is an electroencephalogram, but analyses of this have reportedly identified mismatches between qualitative and quantitative forms, particularly in the use of Delta-alpha ratio (DAR) indices, meaning that the values may be case dependent. The current study thus examines the value of Focused Occipital Beta-Alpha Ratio (FOBAR) as a modified biomarker for evaluating brain functional changes resulting from brain atrophy.

Introduction: The loss of parenchymal brain volume per normative age comparison is a distinctive feature of brain atrophy. While the condition is the most prevalent to elderly, it has also been observed in pediatric ages. Various causes such as trauma, infection, and malnutrition have been reported to trigger the loss of brain tissues volume.
