Summary
Conventional imaging patterns struggle to classify cholangiocarcinoma (CCA). We propose a new dichotomous classification of "parenchymal" and "ductal" types for improved description and correlation of CCA imaging features.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Conventional macroscopic patterns have limitations in classifying cholangiocarcinoma (CCA) imaging features.
- Recent histopathologic advancements provide new insights into CCA carcinogenesis.
Purpose of the Study:
- To propose a novel dichotomous imaging classification for cholangiocarcinoma.
- To enhance the description of underlying carcinogenesis and clinicopathologic correlations in CCA.
Main Methods:
- Development of a new dichotomous imaging classification system for CCA.
- Categorization into "parenchymal" and "ductal" types based on histopathologic concepts.
Main Results:
- The proposed classification is simple and easy to apply.
- It offers a framework to describe CCA carcinogenesis.
- It facilitates correlation between clinicopathologic characteristics and imaging patterns.
Conclusions:
- A dichotomous "parenchymal" and "ductal" imaging classification for CCA is proposed.
- This classification addresses limitations of conventional methods.
- It aids in understanding CCA biology and clinical presentation through imaging.

Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.

Titrimetric analysis in solution chemistry involves measuring the volume of solutions and is often called volumetric analysis. The standard solution of known concentration in the burette is called the titrant, whereas the solution of unknown concentration in the flask is called the analyte, or titrand. Titrimetric analyses can be classified into four types based on the reactions between the titrant and analyte.

Cardiovascular diseases, encompassing a range of conditions, can significantly affect the heart's operations and the overall circulatory system. These conditions impair the heart's ability to pump blood, leading to a deficit in oxygen supply to crucial organs. Anomalies in the heart's electrical system, known as arrhythmias, can cause heartbeats to accelerate or slow down. Usually, heart rates increase during physical activity and decrease while resting or sleeping. However,...

01:20Understanding Self-Concept
243
The self-concept encompasses individuals' beliefs about themselves, structured through cognitive frameworks known as self-schemas. These schemas function as mental representations of specific traits or behaviors, influencing how self-relevant information is perceived, processed, and remembered. For example, individuals who are schematic for body weight are more likely to interpret routine experiences—such as dining out or shopping—through the lens of that trait. Conversely, those...
