The artificial intelligence applied in the diagnosis of diseases

Artificial intelligence is found in every aspect of daily life; including, in the diagnosis and treatment of multiple pathologies. How does it work?

The diagnosis of diseases has always been in charge of health personnel qualified for it. Sin embargo, los programas tecnológicos avanzaron en los ultimos años, pudiendo servir de soporte. We will talk a bit more about the artificial intelligence applied in the diagnosis of diseases.

Artificial intelligence and medicine have been linked for many years. De hecho, multiple studies establish that este tipo de programs pueden usarse en casi todos los campos de la salud humana. Sin embargo, su uso specific para diagnoser enfermedades aún no ha sido del todo explorado.

A group of experts from Birmingham concluded that artificial intelligence could be applied in the diagnosis of diseases. De hecho, se cree que podría superar a los humanos en la identificación de ciertas patologías.

What is artificial intelligence?

Primero resulta imperative definir lo que es la inteligencia artificial o IA. In simple terms, IA is a set of algorithms that try to replicate the cognitive capacities of the human being. Si bien parece una tecnologia lejana, la usamos todos los días sin siquiera notarlo.

Las funciones comunes, como el debloqueo facial en los mobiles o los assistants de voz, son gracias a la IA. This technology is also applied in agriculture, transport, education and finance.

En el amíto médico existen chatbots que preguntan de forma automatica los symptoms para diagnosar patologías. De esta manera, es posible saber si se padece alguna enfermedad común, como la neumonía.

La IA puede ser simple, de applicación daily para el unbloqueo de un teléfono, por ejemplo. Pero también puede ser compleja y analisar quantitas enormes de datos.

What is e-mail? deep learning?

Today there are multiple forms of artificial intelligence. La más utilizado en el diagnosis de enfermedades es el deep learning.

Este no es más que una rama del machine learningque permite que las machines apprendan de forma automatica sin necessidad de ser programadas. In this sense, the systems will be able to interpret a series of data to make predictions.

Con email deep learning, las computadoras aprenden por sí solas. This was achieved through the recognition of multiple patrons.

The main characteristic is the use of a system of artificial neurons of different levels. In simple terms, the program comprende un dato determinado en el nivel inicial. Luego lo pasa a un nivel superior, where it is combined with other data to produce more complete information.



Can artificial intelligence diagnose diseases?

Ya teniendo un poco más claros los concepts de IA y de deep learning, we can explain with more detail the role of artificial intelligence in the diagnosis of diseases. Hace poco, se publicó la primera bibliographic revision sobre el tema en la revista The Lancet Digital Health.

The investigation was carried out in the University Hospitals Birmingham NHS Foundation Trust. The participants reviewed about 20,500 articles, although less than 1% met the inclusion criteria. A pesar de todo, pudieron concluar que la IA was capable of detecting pathologies with the same precision as el hombre.

Las enfermedades diagnosed with IA iban desde cánceres hasta problemas con la vista. The experts analyzed a total of 14 studies, mediate los cuales determinaron que IA diagnosed the disease in 87% of the cases. Lo que superaría al personal médico, el cual se encontraba en un índice sensibilità del 86%.

Por su parte, the technology was capable of identifying a healthy person in 93% of cases. The health staff also excelled in this aspect, reaching only 91%.

Other studies on IA and health

The quantity of studies that involve artificial intelligence in the diagnosis of diseases grew exponentially in the last years. In fact, it was implemented even in the diagnosis and treatment of emerging diseases, such as COVID-19.

Un estudio publicado en International Journal of Biological Sciencesdemostró que AI was used in the analysis of images for the diagnosis of COVID-19. De esta manera, se aceleraba el proceso y se agilizaba la atención a los pacientes en plena pandemia.

Por otro lado, un artículo de la revista Current Oncology determined that the IA is used in the diagnosis of different types of cancer. De hecho, las tecniques de cribado para câncer colorectal asistidas por inteligenia artificial representan un paso crucial en la diminución de la incidence de la neoplasia.

Cardiology has also benefited from IA. This technology has become a fundamental tool for the diagnosis of cardiovascular diseases. Esto se debe a que analiza de forma más precisa un echocardiograma, por ejemplo.

AI has more speed for reading images, which speeds up diagnostic processes.


A technology that still needs to be perfected

The results of the first bibliographic review and other studies on the application of artificial intelligence in the diagnosis of diseases are promising. embargo, se trata de una tecnología reciente que necesita perfeccionarse para diminuir la probability de errores y sesgos.

Por su parte, la ausencia de estudios verificados y confiables sobre la applicación de esta tecnología hinderant su avance. In this sense, we only have to wait a few years and see how scientific findings evolve to be able to count on AI in any health center in the world.
