This paper explores the role of metrology in the assessment of image quality in the field of radiomics. Image Quality Assessment (IQA) is central to ensuring the reliability and reproducibility of radiomic analyses, as it directly affects the accuracy of feature extraction and segmentation, ultimately impacting diagnostic outcomes. From the analysis of approximately 20,000 papers sourced from three databases (PubMed, Scopus, IEEE Xplore), last searched in December 2025, the need for standardized imaging protocols and quality control measures emerges as a critical theme. Studies were included if they involved radiomic feature extraction and evaluated the impact of image quality variations on feature robustness and no formal risk-of-bias assessment was performed. A total of 105 studies were included, covering different medical imaging modalities. Across the included studies, noise, motion, acquisition and reconstruction parameters, and other artifacts consistently emerged as major sources of radiomic feature instability. Indeed, in most papers, IQA is neglected, while the effect of poor-quality images is reported. This research identifies and discusses the relevant issues reported in clinical practice, as well as the main metrics adopted for image quality evaluation. Through a comprehensive review of current literature and an analysis of emerging trends, this paper highlights the urgent need for innovative solutions in image quality metrics tailored to radiomics applications.

To see if CT and MR imaging are useful tools in age estimation it is best to focus on the research with a large number of teeth and an even distribution of age in the test population, the highest correlation coefficient and comparison with conventional radiographs, so that we can see if the method can be an alternative to two-dimensional imaging.
In all articles the selection criteria were also good health, normal growth and dental conditions, and in the case of third molars no head injuries that affected the visualization of the tooth. ( 14 ) Teeth with metal restorations were excluded on CT because of the artefacts. ( 15 )
The year the research was carried out is important because the imaging quality is better when modern machines are used and the scanning protocols have improved with experience. The various CBCT systems available differ with certain technical characteristics like the spatial resolution, the field of exploration and the contrast. ( 20 ) With large sample sizes and the newest CBCT operating modes and optimized software the research will be even more reliable. ( 20 ) The latest multi-detector scanners are able to provide thinner slice thickness which is optimal for assessing dental development. ( 5 ) All this can influence the accuracy.
As several studies have shown that there are differences in development between girls and boys, both genders ought to be represented. ( 21 - 24 ) Aboshi et al. used mandibular premolars as they are less prone to damage when compared to canines and incisors and they have simpler and more stable root morphology when compared to molar teeth. ( 25 ) There might be differences between upper and lower jaw as well as regional variations, but there is no difference between right and left side of the jaw. ( 14 , 23 , 24 )
The stage of tooth development determines the method of age estimation. Pulp cavity/tooth volume is used when the roots are completed, while methods with
