AI in Medical Image Analysis — A Revolution in Radiology
Radiology is the field where AI has made the greatest breakthrough. As many as 75–80% of all FDA-approved AI medical devices are in the field of radiology, according to data from December 2025. The reason is clear: medical image analysis is a perfect task for machine learning — large volumes of data, recognizable patterns, and a need for speed and precision.
In 2024, more than half of healthcare providers were actively using AI for at least one medical imaging task, compared to just 17% in 2018. A 2024 European radiologist survey found that 48% of respondents actively use AI tools, with another 25% planning to do so.

Breast Cancer Detection: A Case Study Changing Medicine
Breast cancer is the most common cancer in the world — according to WHO estimates, it accounts for 12.5% of all new annual cancer cases, and claims more than 670,000 lives every year. Early diagnosis is critical: if diagnosed at an early stage, more than 90% of patients can be cured, and the five-year survival rate is 96%.
This is precisely where AI demonstrates its true value. A study by researchers at the University of Aberdeen showed that an AI tool increases the breast cancer detection rate, particularly for forms that are harder to spot on traditional screenings. Early results show that AI can be especially useful as a supplement to medical staff, not a replacement — the system works in collaboration with radiologists, shortens analysis time and reduces the number of missed cases without increasing false positive diagnoses.
At the regional level, the JMM team from the AI4Health.Cro innovation competition developed a prototype application that uses artificial intelligence to identify potentially cancerous lesions on breast mammograms according to the BI-RADS system, which is important for assessing the degree of breast cancer risk. This shows that the region is beginning to actively work on AI solutions for healthcare.
How AI Analyzes Medical Images — A Technical Overview
- ✓ Convolutional neural networks (CNN) — the foundation of most AI imaging tools; they learn hierarchical image features and excel at lesion detection, segmentation and tumor classification
- ✓ Foundation models (such as MedGemma) — trained on vast amounts of unlabeled data, they can process both images and text simultaneously and generate radiology reports
- ✓ Generative models (diffusion models, GANs) — used for image reconstruction and synthesis of high-quality CT/MRI scans from lower-dose images
- ✓ Deep learning algorithms — improve the speed and accuracy of image processing in radiology, pathology and ophthalmology, resulting in fewer diagnostic errors
- ✓ DICOM support — modern AI tools such as MedGemma integrate directly with the standard medical imaging format in clinical environments
Google MedGemma and Med-Gemini: The Most Advanced AI for Medicine
Google DeepMind and Google Research have developed a family of medical AI models that represent a new frontier in the application of artificial intelligence in healthcare. Med-Gemini is a clinical AI model that supports medical diagnostics, interpretation of radiological images, treatment planning, summarization of electronic health records (EHR) and analysis of genomic data.
The concrete results are impressive: MedGemma 4B achieves 64.4% on the MedQA benchmark, placing it among the best models below 8 billion parameters. In a non-blinded study, 81% of chest X-ray reports generated by MedGemma 4B were rated by US board-certified radiologists as sufficiently accurate to make similar patient management decisions as the original radiologists. On the MedQA (USMLE-style) benchmark, Med-Gemini achieves an accuracy of 91.1%, setting a new industry benchmark.
MedGemma 1.5 4B also brings concrete improvements in anatomical localization — a 35% improvement in intersection over union on the Chest ImaGenome benchmark. All models can be run on a single GPU, and MedGemma 4B can be adapted even for mobile hardware.
"The adoption of artificial intelligence in healthcare is accelerating dramatically, with the healthcare industry adopting AI twice as fast as the broader economy.

Regulation: EU AI Act and Medical Devices in 2026
The regulatory landscape for AI in healthcare is undergoing a major transformation. The EU AI Act entered into force in August 2025, and from August 2026 most provisions for high-risk AI systems become binding. Medical AI devices that serve as safety components or are themselves regulated products under the EU MDR are classified as high-risk AI systems, requiring technical documentation, risk management, human oversight and transparency.
Penalties for violating the EU AI Act can reach up to 7% of a company's annual revenue. For healthcare organizations and manufacturers of medical AI devices, this means that proactive compliance is not only an ethical obligation but also a strategic necessity. Montenegro, as an EU candidate country, will face increasing pressure to align its regulations with these standards.
Montenegro and AI in Healthcare — Where We Are and Where We Are Headed
Montenegro is actively positioning itself in the global AI economy. At the Second National Conference "AI DIRECTLY: Montenegro in the Age of AI Challenges" in December 2025, Prime Minister Milojko Spajić presented the Government's strategic vision focused on accelerated digital development and positioning Montenegro in the global AI economy, including the application of AI in healthcare. A panel discussion on the application of AI in healthcare was one of the three central thematic blocks of the conference.
UNDP's AI Landscape Assessment (AILA) report for Montenegro from 2024 shows that the country has a well-established regulatory framework for data governance (score of 4.6 out of 5 — transformational phase), providing a solid foundation for the responsible introduction of AI in healthcare. However, digital infrastructure and AI-specific capacities still require investment.
The European Commission has launched the SHAIPED project, which since March 2025 has been piloting the development, validation and deployment of AI models using the HealthData@EU infrastructure of the European Health Data Space (EHDS) — which entered into force in 2025. Montenegro, as part of its EU integration path, will have the opportunity to connect with these infrastructures and access advanced AI solutions for diagnostics.
Best Practices for Implementing AI in Healthcare Institutions
Recommended Steps for Introducing AI Diagnostics
- 1. Start with clearly defined use cases — do not implement AI "for everything". Identify specific clinical problems: e.g., triaging urgent CT scans or detecting pulmonary nodules.
- 2. Validate on local data — AI models trained on data from the US or UK may perform differently on the population of Montenegro or the region. Local validation is mandatory.
- 3. Ensure human-in-the-loop — AI should be an assistive tool, not a replacement for a physician. Every AI finding must be confirmed by a clinician before a decision is made.
- 4. Integrate with existing systems — AI solutions such as Aidoc or MedGemma integrate with PACS, EHR and DICOM systems without disrupting existing workflows.
- 5. Educate medical staff — the EU AI Act requires appropriate AI literacy among staff. Physicians must understand both the capabilities and limitations of AI tools.
- 6. Establish monitoring and performance tracking — continuously monitor the accuracy of AI systems in real clinical conditions and report any serious incidents to regulatory bodies.
"In 2026, AI diagnostics has evolved from an experimental technology to an essential component of modern healthcare systems. From radiology and pathology to genomics and predictive analytics, AI in medical diagnostics is improving patient outcomes across multiple specialties.
— Scispot, AI Diagnostics: Revolutionizing Medical Diagnosis in 2026
AI in healthcare in 2026 is not a question of the future — it is the present. With more than 1,300 FDA-approved AI medical devices, a global market growing toward 1.222 trillion USD by 2035, and concrete clinical results showing that AI helps radiologists work 25% faster, reduces missed breast cancer diagnoses and gives stroke patients a 66-minute head start in treatment, it is clear that this technology is already part of medical practice in advanced healthcare systems. For Montenegro, which is building its digital infrastructure and aligning with EU standards, introducing AI into diagnostics is not merely a technological step forward — it is an investment in the health of its citizens and the modernization of a healthcare system that must meet the growing needs of patients with limited medical staff resources.
