Artificial Intelligence in Healthcare: Transforming Diagnosis and Treatment*
Revolutionizing Clinical Decision-Making: AI as a Diagnostic and Prognostic Tool
AI in Radiology: Transforming Image Analysis and Interpretation
Among all healthcare subfields, radiology has been positively affected by AI to the greatest extent. For conventional radiology, the interpretation of imaging is done by radiologists and can take a lot of time and may in some circumstances be erroneous. This has however being made easier by the advances in AI, especially Deep Learning models where image analysis and interpretations are done automatically.
Techniques in artificial intelligence can handle images of a patient faster and provide superior diagnosis to that of a human being through image processing. For instance, the use of AI in interpreting mammograms is capable of identifying lesions that are microscopic, hence, possibly providing an early diagnosis of breast cancer than could be achieved using traditional diagnosis. In the same way, in lung imaging AI can find out the nodules that may suggest the early-stage lung cancer, and in turn patients can get an early treatment.
Apart from cancer diagnosis, AI is being utilised in other radiological practices. In musculoskeletal imaging, AI is known to help in the identification of fractures and other injuries with much precision. In cardiovascular diagnosis for example, AI can inspect echocardiograms and CT angiograms for purposes of evaluating heart function and identifying diseases including coronary artery disease. AI integration into radiology not only increases the diagnostic performance but also optimizes the practices of radiology providing the opportunity to radiologists to concentrate on those cases which require them.

Natural Language Processing (NLP) the subfield of AI that deals with the interaction of computers with natural languages is extremely relevant to healthcare. NLP Technologies derived from the Text Mining subfield have the ability to extract valuable information from large unstructured datasets: clinical notes, research papers, patient records, etc., that used to be reviewed manually.
In the domain of healthcare, NLP is applied to derivate high-value information from the EHRs including patient history, the treatment plan, and diagnostic outcomes. This capability is beneficial not only to healthcare providers as it saves more time but also less prone to errors as compare to manual entry of data. Moreover, NLP could detect some other patterns and cycles in the information about patients that could be unseen from the primary counseling.
For instance, NLP algorithms can extract patients’ notes to diagnose potential risk factors concerning particular diseases such as heart diseases, or diabetes among others. In this sense, NLP could give clinicians indications concerning risk factors, so that they may prevent or monitor patients with certain characteristics. In practice, NLP is applied in reviewing mountains of published articles, comparatively analyzing articles for results that can then be used in creating or updating clinical pathways.
Patient relation is also an important function of NLP. NLP is already powering more and more chatbots delivering patients’ information, answering questions or even walking through the process of symptom evaluation. These chatbots, online at all times, improve the efficiency of information delivery to the patients and, thus, their satisfaction, as well as relieve the healthcare professionals.

Genomics, where the focus is on an individual’s genes and the roles that they play, is yet another field in which AI is advancing at a great pace. The nature of genomic data is labyrinthine, compounded by the magnitude of genomics data sets; these characteristics make genomic data well-suited to AI analysis. The data can be analyzed by the AI algorithms so as to recognize mutation, variation and patterns underlying certain diseases; In this way, diagnosis of the diseases would be more precise and the therapeutic and palliative care measures tailored to the affected individuals.
In the case of the rare diseases, the capability of the AI algorithm to interpret the genome rapidly and to high degree of accuracy is especially beneficial. Most of the rare diseases are genetically determined, but in order to define genetic fundamentals, it can take a lot of time using conventional approaches. While it may require the patient to sit for hours while every stratum of his DNA is tested in order to identify the specific mutation that caused the disease, with the subsequent development of disease-specific treatment options, modern algorithms can achieve all of this in matter of hours.
AI is applied in oncology: the genetic analysis of malignant tumors to determine which therapy is more effective. When a clinician knows the genetic basis of a particular tumor, he can then choose treatments that are relevant to these mutations, and hence have the high chances of treating the tumor. This approach is known as precision oncology and is revoluionizing oncology as the prospects help the patients who hitherto had poor chances of survival.
In addition, AI promotes the understanding of the ways in which genes are affected by other factors such as environments and lifestyle in deciding the level of health and disease. When genetics is combined with lifestyle data such as diet and exercise AI can make recommendations concerning disease prevention and overall health.

The application of AI in the sphere of mental health is another promising area in the field of psychiatry that draws people’s attention to novel ways of diagnosing and treating diseases and supporting patients. The mental health disorders are not simple and usually have polygenic components and are therefore difficult to diagnose and treat conventionally. Technology in the form of AI is starting to fill this void for what therapists can do after diagnosis by bringing analytical tools to behavioral data, symptom tracking, and sometimes even predicting the onset of actual mental health emergencies.
There are new applications and platforms being designed to address patients’ psychological health with information collected by worn devices and smartphones in real-time. It has features that can monitor the fluctuations in behaviour, for instance, lack of sleep, muscle movement, social interactions which are pointers towards deteriorating mental health. These changes, if detected, in advance may call for interventions that may help in averting a crisis in mental health.
Besides, the use of artificial intelligence has been extended to involve formulation of individualized treatment plans for mental diseases. Patients’ characteristics can be and recorded, and then fed into the machine learning algorithms, which in their turn can identify which therapy will be most effective for this particular patient. This approach is quite useful when it comes to the general treatment of conditions such as depression and anxiety, given that courses of treatment can be generally inconsistent among patients.
AI also is being applied to assist mental health practitioners in making diagnosis and their treatment directions. For instance, the proposed AI can take the patient’s responses to questionnaires and clinical interviews and then detect certain patterns that lead to a set of diagnoses or treatment requirements. This not only helps in the better assessment of the patients and in formulation of treatment plans but it also enables the mental health professionals to work on the development of rapport with the patients.

Perhaps one of the most significant hurdles towards the implementation of AI in healthcare is the question of the quality and the credibility of data feed to AI sets. It is common to have various types of data, which are scattered and not integrated in healthcare organisations. The inclusion and validation of this data becomes important for the creation of sound AI models. Furthermore, as AI applications continue to be incorporated in and integrated with the clinical settings, there will be the need to adopt techniques that would make these systems transparent, explainable, and unbiased.
There are also cultural factors; first, of the patients who will undergo the various diagnostic tests and secondly, of the use of their information for educational purposes among others. Incorporation of AI in heath care calls for storage, sharing and usage of large amount of highly sensitive patient information. The protection of the patient’s data means that AI systems must meet the data protection acts, and the patients must be aware of how their data will be used.
Another important domain, the regulation of which will require changes as AI becomes more prevalent, is the sphere of legal requirements. It is important to understand that the existing legal systems may not cope well with such AI-related aspects as the algorithms’ explainability and verifiability. It will be imperative that regulators create new standards that will be better placed in the leadership of technological change if AI is to be utilized safely in the health sector.
