Recent advancements in AI have significantly enhanced anatomical segmentation and oncological imaging, achieving Dice similarity coefficients up to 0.99, indicating near-perfect overlap with manual segmentations.
For the diagnostic radiologist, manual delineation of hepatic contours and tumor margins introduces variability that can delay treatment planning. Innovations in AI have streamlined liver segmentation processes, making them more reliable and accurate as evidenced by recent studies on AI-based liver segmentation. This approach significantly enhances the accuracy and efficiency of liver volume measurement, which is crucial for patient monitoring and therapeutic decision-making.
Beyond hepatic assessments, integrating AI with 3D quantitative CT scans has improved airway obstruction detection, achieving sensitivity and specificity rates of 95% and 98%, respectively. The adoption of machine-learning models for volumetric airway analysis shows a strong correlation with pulmonary function tests, with Pearson correlation coefficients exceeding 0.9, offering a more objective assessment of obstructive airway diseases than visual grading alone.
In the oncological arena, precise surface segmentation is essential for staging and guiding interventions. The application of two-stream MeshCNN, a convolutional neural network designed for processing 3D mesh data through dual processing streams, has advanced visualization of tumor margins and parenchymal structures, reinforcing diagnostic confidence for multidisciplinary teams. Earlier findings indicate that enhanced liver surface models facilitate more accurate tumor characterization, supporting tailored therapeutic strategies.
Pediatric oncology also benefits from AI-driven parameter optimization. Accurate tuning of diffusion-weighted imaging settings yields more reliable apparent diffusion coefficient values in small tumors such as rhabdomyosarcoma according to the recent analysis of the impact of AI on scan parameters. This refinement improves lesion conspicuity and quantitative assessment without prolonging acquisition time.
Together, these developments illustrate a shift toward AI-driven diagnostics that streamline workflows and deliver quantifiable improvements in treatment planning across adult and pediatric populations. Radiologists should consider integrating validated AI tools into routine practice, adhering to standardized implementation guidelines from organizations like the American College of Radiology (ACR) and the Radiological Society of North America (RSNA) to ensure consistency across institutions and reduce interobserver variability.
