Precision medicine is entering a new age with the swift integration of artificial intelligence (AI) into healthcare, especially in oncology. Cancer diagnosis, prognosis, and treatment planning are being revolutionized by AI-powered diagnostic technologies. Since cancer is still one of the biggest causes of mortality globally, enhancing patient outcomes depends on early identification and precise diagnosis. AI technologies significantly improve the precision, speed, and personalization of cancer diagnosis through the use of sophisticated algorithms, big data, and machine learning. This article delves into the need of AI in oncology and ways where AI integration can happen.
AI is ideally positioned to address a number of the issues that oncology diagnostics encounter. Conventional diagnostic techniques, including imaging, biopsies, and laboratory testing, frequently depend on subjective and error-prone human interpretation. Accurate diagnosis of cancer is made more challenging by the disease's complexity, which includes a wide range of subtypes and differences in genetic alterations. Additionally, it is extremely difficult for human practitioners to perform a thorough analysis due to the enormous number of data generated in current cancer care, from genetic sequencing to imaging studies.
AI-powered solutions are excellent at precisely organizing and evaluating big datasets. By spotting patterns and correlations in data that might not be immediately obvious to the human eye, they are intended to increase diagnostic precision and lower the possibility of error.
Artificial intelligence (AI) systems used in oncology mostly rely on machine learning and deep learning, letting computers learn from massive datasets and classify or predict things. To create these systems, artificial intelligence (AI) models must be trained on enormous volumes of labeled data, such as patient records or medical images, for them to identify particular characteristics of cancer.
a. Image Acquisition Optimization
Frequent imaging procedures for cancer patients expose them to radiation, cumulative contrast doses, and sometimes extended tests (if an MRI is performed). Transferring images from one high-dimensional data space to another is an efficient task for deep neural networks. As a result, oncology patients may benefit from several innovative applications, including decreased contrast/radiotracer dosage, quicker MRI acquisition, and CT-dose reduction.
b. CT-Dose Reduction
A CT image can be transferred from the low-dose or high-noise space to the high-dose or low-noise representation using deep neural networks' ability to map data from one high-dimensional data space to another. To drastically lower radiation exposure, new methods based on deep learning reconstruction (DLR) are presently being developed. In 2019, two DLR solutions were approved by the FDA and made available for clinical use.
Reconstruction techniques based on DLR have reduced radiation exposure and/or enhanced image quality while providing a respectably quick reconstruction time. A recent DLR pilot study described volumetric tomographic imaging that was produced using a patient-specific prior and ultrasparse data sampling, or single projection, which, if confirmed, can further minimize the radiation exposure.
c. Optimization of MRI Acquisition
In oncologic imaging, magnetic resonance imaging, or MRI, is essential. Since whole-body MRI has been available, it can also be used as a staging, therapy response assessment, and surveillance tool in addition to being a problem-solving tool for lesion characterization, local assessment, and tumor staging.
Long scan durations can cause motion artifacts, increase costs, and cause pain for patients, making it one of the most difficult problems to deal with. These problems might be resolved by recent advancements in AI. For instance, under-sampling in deep learning-based techniques has been used to speed up MRI scan times. These techniques fall into numerous categories and include image-based reconstruction, k-space-based reconstruction, adversarial networks, and super-resolution.
AI algorithms will probably become a crucial component of cancer treatment as they advance and become more widely available. Current constraints will be partially addressed by ongoing developments in data privacy, model openness, and cooperation between technology businesses and healthcare providers.
AI-powered technologies are expected to be more prevalent in the future when it comes to tracking the course of diseases, forecasting the risk of cancer, and even offering tailored preventive care. AI can save many lives and change oncology from a reactive to a proactive field by increasing early detection and diagnostic accuracy.
The use of AI in oncology is revolutionizing the way that cancer is diagnosed and treated. AI is tackling many of the problems with traditional diagnostic techniques by processing large datasets, minimizing human error, and revealing patterns that are frequently hidden from human sight.
AI-powered technologies are increasing the efficiency and precision of cancer diagnosis through the optimization of imaging acquisition, the reduction of radiation exposure, and the improvement of MRI scan times. AI will become a key component of precision medicine as these technologies advance, allowing for earlier diagnosis, more individualized treatment regimens, and improved patient outcomes. AI in oncology is expected to shift treatment from reactive to proactive, giving patients renewed hope in the battle against cancer.
