Resumen
Este estudio presenta una red multimodal basada en atención con cadena de bloques para mejorar la detección de cálculos renales mediante ecografía. El modelo de IA logra una alta precisión, mejorando el diagnóstico temprano y previniendo la insuficiencia renal.
Área de la Ciencia:
- Imagenología Médica
- Inteligencia Artificial
- Tecnología de Cadena de Bloques
Sus antecedentes:
- Los cálculos renales (litiasis renal) obstruyen el sistema renal, lo que puede provocar enfermedad renal crónica e insuficiencia renal.
- La detección temprana de cálculos renales es crucial para prevenir complicaciones irreversibles como cicatrices e insuficiencia renal.
- La ecografía para la detección de cálculos renales enfrenta desafíos debido al ruido de moteado, bajo contraste de tejido y variabilidad anatómica.
Objetivo del estudio:
- Desarrollar una novedosa red multimodal impulsada por atención integrada con cadena de bloques para mejorar la detección de cálculos renales.
- Abordar las limitaciones de la ecografía tradicional en la identificación de cálculos renales.
- Garantizar la privacidad, integridad y auditabilidad de los datos en aplicaciones clínicas utilizando la cadena de bloques.
Principales métodos:
- Se propuso una red multimodal impulsada por atención que integra representaciones de datos globales y locales.
- Se desarrolló un módulo de fusión de atención cruzada con una capa de interpretabilidad para una extracción de características robusta.
- Se utilizó tecnología de cadena de bloques con contratos inteligentes para una gestión de datos segura y auditable.
Principales resultados:
- La red multimodal impulsada por atención logró una precisión diagnóstica del 98,5 % y un AUC del 99,1 %.
- El modelo desarrollado demostró un rendimiento superior en la detección de cálculos renales en comparación con los métodos existentes.
- La integración de la cadena de bloques garantizó la privacidad, integridad y auditabilidad de los datos médicos.
Conclusiones:
- La red multimodal impulsada por atención ofrece una solución segura y confiable para la detección de cálculos renales en la atención médica.

Types of Building Stone
448
Building stones, essential materials for construction, are extracted from natural rock deposits and processed into specific forms and dimensions suitable for various building applications. These stones are broadly classified into three types based on their geological formation: igneous, sedimentary, and metamorphic.
Igneous rocks are formed from the solidification of magma or lava. An example is granite, known for its durability and resistance to weathering, making it ideal for parts of...

Reliability and Validity
13.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Quarrying of Stone
586
Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the...

Stone Masonry
482
Stone masonry is a construction technique that uses individual stones to build structures and can be categorized into two main types: rubble and ashlar. Rubble masonry uses uneven, naturally shaped stones such as river rocks or fragments from quarries. This method often requires the mason to select and possibly shape each stone to fit the designated space, ensuring a proper build, even with irregular stone sizes and shapes. Ashlar masonry, on the other hand, employs uniformly cut stones that...

Kidney Structure
75.3K
The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

Protein Networks
4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
