Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
Volume of Distribution01:20

Volume of Distribution

The apparent volume of distribution (Vd) is a crucial pharmacokinetic parameter representing the hypothetical body fluid volume into which a drug disperses. It is calculated based on the total amount of drug in the body (estimated from the administered dose and bioavailability) divided by the plasma drug concentration. The total amount of drug in the body does not directly refer to the dose given but is derived by accounting for absorption, distribution, metabolism, and excretion processes.
Increased Intracranial Pressure l: Introduction01:14

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
Cerebral Edema l: Introduction01:19

Cerebral Edema l: Introduction

Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...

Summary

This study establishes new reference curves for intracranial volume in a normal white population using computed tomography. Findings reveal differences compared to existing data, particularly in early childhood, impacting craniosynostosis assessments.

Area of Science:

  • Neuroimaging
  • Pediatric Radiology
  • Human Anatomy

Background:

  • Existing intracranial volume reference data may be inaccurate, potentially affecting diagnoses like craniosynostosis.
  • Computed tomography (CT) offers a precise method for measuring intracranial volume.

Purpose of the Study:

  • To establish normative intracranial volume reference curves for a white population using CT data.
  • To compare these new curves with existing historical references.
  • To refine understanding of intracranial volume development in children.

Main Methods:

  • Intracranial volumes of 157 white subjects (82 female, 75 male) were measured using CT and the Cavalieri estimator.
  • Monomolecular and Gompertz models were applied to fit intracranial volume as a function of age.
  • The monomolecular model provided the best fit using logarithmically transformed intracranial volume and age from conception.

Main Results:

  • New intracranial volume reference curves were generated for males and females.
  • Male and female curves showed similar growth patterns, but females had a lower mean volume at age 20.
  • The new male curves were higher than historical references (Blinkov, Lichtenberg, Dekaban) from 8 months to 4 years.
  • The new female curves differed from Lichtenberg's, particularly after 41 months.

Conclusions:

  • The developed CT-based intracranial volume curves provide a more current reference for a white population.
  • Significant deviations from historical data suggest a need to update reference materials for conditions like craniosynostosis.
  • Ninety-five percent of final intracranial volume is reached by approximately 42 months for girls and 46 months for boys.
