Summary
Physiologic intracranial calcifications are common incidental findings in cone beam computed tomography (CBCT) scans of the Turkish population. These calcifications, including habenular and petroclinoid ligament, were observed in 33.1% of patients, with no significant age or gender correlation.
Area of Science:
- Radiology
- Neuroimaging
- Dental Imaging
Background:
- Cone beam computed tomography (CBCT) is frequently used in dental diagnostics.
- Intracranial calcifications can be incidental findings during imaging procedures.
Purpose of the Study:
- To determine the incidence of physiologic intracranial calcifications in a Turkish subpopulation using CBCT.
- To investigate the prevalence of specific calcifications like habenular, petroclinoid ligament, choroid plexus, interclinoid ligament (ICL), and carotico-clinoid ligament (CCL).
Main Methods:
- Retrospective analysis of 573 full-head CBCT scans taken between 2015 and 2018.
- Evaluation for the presence and type of intracranial calcifications.
- Recording patient age and gender.
Main Results:
- Intracranial calcifications were detected in 190 (33.1%) of the 573 patients.
- Habenular calcification was the most frequent (19.2%), followed by ICL (4.88%), CCL (3.83%), petroclinoid ligament (2.7%), and choroid plexus (2.4%).
- No statistically significant association was found between the presence of calcifications and patient age or gender.
Conclusions:
- Physiologic intracranial calcifications are common incidental findings in CBCT imaging.
- CBCT serves as a valuable tool for detecting these incidental intracranial calcifications.

Beams are integral components of structural engineering and construction, designed to support loads applied at various points along their length. These long, straight members can be classified based on geometry, cross-section, support type, and equilibrium condition.
Based on geometry, beams can be straight, tapered, or curved. Straight beams are the most common type and have a constant cross-section throughout their length. Tapered beams, on the other hand, have a varying cross-section along...

Accurately determining beam deflection and slope under various loading conditions in structural engineering is crucial for ensuring safety and structural integrity. Singularity functions offer a streamlined approach to analyzing beams, especially when multiple loading functions complicate the bending moment equation.

In the design of a supported timber beam subjected to a distributed load, both the beam's physical dimensions and the timber's characteristics, such as its grade and species, are critical. These factors determine the allowable stress values, which are crucial for calculating the necessary beam depth to ensure structural integrity and safety.
The design begins with analyzing the beam as a free body to identify moments and force balances, thereby determining support reactions. Next, the...

In prismatic beams subject to arbitrary transverse loading, It is essential to analyze the interaction between shear forces and bending moments in order to understand stress distribution and ensure structural integrity. The highest normal or bending stress occurs at the outer fibers of the beam, decreasing linearly to zero at the neutral axis. In contrast, shear stress peaks at the neutral axis and diminishes toward the outer surfaces.

The moment-area method is an analytical tool used in structural engineering to determine the slope and deflection of beams under various loads. Consider a cantilever with a concentrated load and moment at the free end. The first step is constructing a free-body diagram to calculate the reactions at the fixed end. Next, the bending moment diagram is plotted to visualize how the bending moment varies along the beam's length, focusing on points where the bending moment equals zero.

Analyzing a supported beam under unsymmetrical loadings is essential in structural engineering to understand how beams respond to varied force distributions. This analysis involves calculating the deflection and identifying points where the slope of the beam is zero, which are crucial for ensuring structural stability and functionality.
