The countless possibilities have led to a significant rise in AI-based imaging modality systems across the globe. The growth has fueled the rapid evolution in deep learning techniques and an increasing number of cross-industry partnerships.

Top Use Cases of AI in Medical Imaging

Let’s look at some of the real-life use cases of AI in medical imaging.

1. Screening Common Cancers

At heart, most software curators have the desire to improve the efficacy of clinical care continues, which includes AI.

Within cancer imaging, AI finds excellent utility in performing clinical tasks that include detection, characterization, and tumor monitoring.

• Detection: At this stage, AI-based detection tools can reduce observational oversights and errors of omission.
• Characterization: The task broadly captures the diagnosis, segmentation, and staging of tumors. It provides robust tumor descriptors that help to capture intra-tumor heterogeneity and variability.
• Monitoring: AI can play a significant role in monitoring changes in a tumor over time. Temporal tracking of tumor changes either in natural history or in response to treatment.

Medical imaging finds a significant spot in preventive screenings of cancers, such as lung cancer, breast cancer, and colon cancer.

For example, according to experts, medical imaging in AI plays a vital role in improving the early detection and characterization of lung cancer.

It can differentiate benign from malignant nodules. Early detection and improved accuracy can help improve patient outcomes and minimal overtreatment. The diseases detected at early stages are often curable.

Furthermore, AI can also enhance lung cancer staging and characterization and monitoring treatment response. It can use quantitative imaging features to categorize microcalcifications more accurately. In fact, the technology can potentially decrease the rate of unnecessary benign biopsies.

2. Identifying Risks for Cardiovascular Diseases

AI techniques such as machine learning (ML), cognitive computing, and deep learning (DL) have immense potential to change how cardiology and cardiovascular medicine are practiced, especially in cardiovascular imaging.

It can help measure the various structures of the heart and reveal an individual’s risk for cardiovascular diseases.

AI can identify problems that may need to be addressed through surgery or pharmacological management. Automating the detection of abnormalities in commonly-ordered imaging tests, such as chest x-rays, will not only expedite decision-making but also reduce diagnostic errors.

So, think for a moment, if a patient lands up in an emergency healthcare unit, complaining of shortness of breath, the chest radiograph as the first imaging study can be helpful.

It can be used as an initial screening tool for cardiomegaly, and medical professionals can use it as a marker for heart disease.

In fact, Zebra Medical Vision and Clalit Health Services presented a research project that allows the early identification of patients with cardiovascular disease using AI. Using existing computed tomography (CT) data, Zebra-Med’s AI algorithms allow Clalit find out patients who are at risk of cardiac events.

In the future, radiologists’ visual assessments that are sometimes erroneous can transcend to efficient use of AI. For example, identification of left atrial enlargement from chest x-rays could eliminate other cardiac or pulmonary problems.

Furthermore, it can help providers target appropriate treatments for patients. Subsequently, automated pulmonary artery flow quantification would save the interpreting physician time.

3. Accuracy in the Diagnosis of Neurological Diseases

Over the past decade, computed tomography (CT), positron emission tomography (PET), and magnetic resonance imaging (MRI) have revolutionized the study of the brain.

Experts estimate the day-to-day error rates and discrepancies in radiology are greater than 3%-5%. It is evident that novel methods and advanced medical imaging software can help physicians effectively analyze data.

The quality of medical data will increase, which can support better disease analysis and control.

Think for a moment—there is no cure for some degenerative neurological diseases, such as amyotrophic lateral sclerosis (ALS). In such cases, accurate diagnoses can help individuals understand likely outcomes and also prepare for long-term care.

Imaging studies are critical in identifying ALS and also differentiating ALS and primary lateral sclerosis (PLS). Radiologists play a crucial role in deciding if lesions are mimicking the structures of one of the diseases.

Medical professionals know that manual segmentation and quantitative susceptibility mapping (QSM) assessments of the motor cortex are difficult, necessary, and time-consuming.

ML techniques are now increasingly popular for addressing brain-related problems. Automating such procedures with ML could aid in the development of promising imaging biomarkers. Such novel initiatives can help to reduce workflow burdens on providers.

4. Detecting Thoracic Complications

Pneumonia and pneumothorax can turn into a life-threatening emergency due to lung collapse and respiratory or circulatory distress. Delays in the detection and treating serious pneumothorax can result in severe harm to patients. In such cases, artificial algorithms can aid physicians.

Radiology images are popularly used to diagnose pneumonia and distinguish the condition from other lung conditions, such as bronchitis. However, radiologists aren’t always available to read images.

Even when radiologists are present, they may still have difficulty detecting pneumonia in cases where patients have pre-existing lung conditions, including cystic fibrosis or malignancies.

Here, an AI algorithm could assess x-rays and other images for evidence of opacities that indicate pneumonia. Subsequently, it can alert healthcare providers to the potential diagnoses and allow swifter treatment.

Furthermore, computer algorithms, backed with high-quality training data, could help detect pneumothorax on a chest X-ray with significant accuracy to help prioritize images for quick review by physicians.

Radiologists could potentially use algorithms as a tool to increase the speed with which a severe pneumothorax is detected, especially at times of lower staffing, when turnaround times are typically longer.

Let’s look at a good example that reiterates accuracy in the detection of thoracic complications and conditions. In a research study, algorithms could detect the majority (80%–84%) of images showing a moderate or large pneumothorax while correctly categorizing 90% or more of images without pneumothorax as negative.

So, the implementation of such algorithms can improve the speed and quality of care delivered across various healthcare settings. Plus, AI may also be able to help providers monitor patients over time.

Rapid detection and swift communication with treating medical professionals may result in faster treatment of pneumothorax and lessening the impacts of a severe medical problem.

Time is critical when treating strokes, so a mobile app that sends notifications directly to the treating physician can be life-saving.

Shortage of Trained and Experienced Radiologists Can Be Solved with AI?

On the one hand, there is an increase in demand for cross-sectional imaging (CT and MRI). On the other, there is a lack of trained radiologists to examine and analyze the images.

Across Europe, there is a massive scarcity of trained radiologists. The UK is facing the worst capacity constraints, with the lowest number of practicing radiologists per capita.

Budgetary constraints and an aging population coupled with the time-consuming process of image analysis is probably the reason for the catastrophic shortage of radiologists across Europe. (Source)
