Introduction:
Artificial intelligence is one of the revolutionary changes that is rapidly developing in the world. This concept of AI in the imaging field has excited some serious changes in neuromedicine and imaging. Artificial intelligence can give patients better output of brain images and associated structures. As artificial intelligence is a recently emerging development and its usage in medical specialties is limited, according to the available data, AI in the field of neuromedicine will be one of the major steps in studying the brain and associated diseases. AI also helps with easier documentation and storage of patient data and revisits it during further treatment procedures.
What Is Neuroimaging?
Neuroimaging is the study of imaging specialized in the brain and its associated structures and any pathologies targeting it. This helps both the physician as well as the patient to get a look into the current state of the brain structure and its functions and to figure out any functional changes or pathology, also enabling them to come up with the best treatment plan if indicated and predict its outcome. Several imaging modalities like computed tomography (CT) (three-dimensional imaging methodology used to view the internal organs of the body), magnetic resonance imaging (MRI) (a diagnostic procedure that uses magnetic and radio waves too, X-rays, positron emission tomography (PET) (a medical imaging technology that uses radioactive substances to give a precise three-dimensional picture of the internal structures of the body) scans etc are used to take pictures of the brain. This gives a collection of pictures showing all the aspects of the brain, making it easy to diagnose.
What Is Artificial Intelligence?
Artificial intelligence in the technology field is rapidly developing and is considered a booming entity in all aspects of medicine. Artificial intelligence is used in diagnosing patients, observing the symptoms, in newer drug development, helps in better forms of communication and understanding between the doctor and the patient, in studying speech recognition, observing eye movements, diagnosis and treatment plan, predicting the diagnosis, for converting medical documents into automated data and reports, managing medico-legal files, allotting prescriptions, making healthcare easily accessible to all. Along with other benefits, AI in medicine is used in medical science and can be used in targeted specialties with exact specifications to provide better treatment for the patients and better outcomes of diseases, how the drugs can be delivered to the patients, etc.
What Are the General Principles Framed While Developing AI?
The considerations that were framed while developing and deploying artificial intelligence are:
-
To promote the individual's well-being, minimize the harmful effects, and ensure more benefits than harm.
-
Aiming to respect human rights and freedom, including privacy and dignity.
-
Being dependable and transparent includes making decisions and control of bias.
How Is AI Applied in Neuroimaging?
In today's scenario, artificial intelligence, being the proficient imaging methodology in the field of neuroscience, is used for various methods like:
-
Slicing of the Structure: As the brain is a mound of intricate structures, imaging methods often use radiation or magnetic waves to slice the brain's structure. Previously, it was stated that around 20 percent of people used it with errors and repetition, which led to the use of AI in imaging. This helped identify any defect present in the brain's structure. However, much finer slices are easily produced with AI, giving a more reliable diagnosis.
-
It helps classify and locate the structures of the brain and associated pathologies.
-
Usage of AI in Measuring the Volume of the Brain and Associated Structures: This enables it to identify any changes in the volume or density-related brain changes.
What Are the Benefits of Using AI in Neuroimaging?
The reason for using this technology is because it provides various benefits to it, and they most likely are:
-
More Accurate and Clear Image Results: The study of brain structure can be very intricate and requires a very sound imaging modality and delivery system. Here is when AI comes in handy: using AI can decrease the time spent on imaging. Imaging methods like MRIs and CTs need time as they process them using a technology known as compressed sensing, which can be time-consuming. Also, this causes distortion and artifacts in the images. Here, the AI system reduces noise in the image and improves resolution, giving a higher clarity image than the normal compressed scans.
-
Reduced Waiting Time: AI is an automated process; unlike the predicting waiting time for image outputs like computed tomography, MRI, etc., AI in neuroimaging gives faster.
-
Easier Detection Of Medical Condition: The imaging modality associated with AI involving brain structures can examine even the minute details of the structure, giving us accurate images and aiding in detecting structures or pathologies from the beginning.
-
Reduces Imaging Doses: As artificial intelligence can read, understand, and describe images from imaging modalities like MRI, CT, and PET scans, the interpreted images are delivered much quicker, thus reducing the dosage.
What Are the Ethical Issues Faced While Performing AI in Neuroimaging?
-
There Is a Very Minimal Availability of Resources: As it is a relatively new technology, few resources are available for information on how to use it, ideally including collecting imaging data, image transfer, etc. Hence, careful handling is indicated.
-
Differences in Opinion: Although the AI system determines the images and conclusions, and although most cases can be feasible, the opinions are sometimes different. In some cases, there is a serious difference in opinions among doctors, algorithms, and radiologists, along with clinical considerations.
-
Disruption of Workforce: There is a hassle in the workplace with the development of AI, as universally claimed AI has been considered as a greater risk for the employment of people; hence, installation of AI-based components can create a disrupted situation among the workers, making it chaotic
-
The Liability of the Images: In the case of manual imaging, the doctor is directly liable for obtaining the image, but in the case of artificially guided imaging, the liable source is not provided to any specific person and is stored in a common cloud in case of any negative outcome, which is a serious drawback.
-
Solutions Gained From the AI Algorithms: As discussed above, factors to be considered in ethics while framing the AI are that the reports given should be unbiased.
-
Risk of Approving and Understanding the Unknown Options: The difficulties in using AI models and the radiologist's understanding of them, etc.
-
Inability to Correlate the Image: As the artificial intelligence system used in imaging is only implemented to detect or capture images of the brain, it cannot correlate this given image with backup data of previous medical records, including the contents of the image being taken.
Conclusion:
The use of artificial intelligence in neuroimaging is promising, with significant innovations in brain research, patient treatment, and our overall understanding of the brain. Artificial intelligence is changing neuroimaging by making brain investigations easier, faster, more precise, and more detailed. AI can quickly analyze massive amounts of imaging data, identifying the structural patterns and errors that medical professionals can overlook. This helps in the better identification of brain diseases like memory loss, multiple sclerosis (MS), and tumors of the brain. AI helps curate customized treatment plans for individual patients as it helps predict the treatment outcome and efficacy. AI also helps neurological studies by detecting novel biomarkers and giving a broader knowledge of brain functions.
