Topic Information

Dear Colleagues,

Radiographic acquisition techniques have undergone tremendous improvements since their invention. Image resolution has greatly increased and the reduction in the dose of X-ray radiation required for its creation has been achieved. The increased amount of imaging data does not necessarily mean that more medical information is accessible to the reader. Some (but often important) information is hidden from the radiologist. This is especially true for radiographic techniques.

The purpose of advanced image-analysis systems is to extract occulted data to improve the objectivity of diagnosis for a given case. The treatment of clinical problems with information obtained using advanced image analyses has increased. In musculoskeletal radiology, proven associations exist between bone scan analyses, patient health and metabolic status. Moreover, the processes of bone maturation, bone healing, bone demineralization and deformation due to overuse can be extensively analyzed with the use of CR, CT and MRI. Advanced methods significantly improve differentiation and hence the diagnostic process of medication for different lesions including neoplasms of the bone.

Papers investigating the application of both classical image processing and artificial intelligence (AI) methods in the analysis and extraction of diagnostically useful data from medical images are welcomed in this Special Issue. Such methods assist in the investigation of the shape and geometry of, for example, bone tissue or its fragments. Other AI approaches allow for the automatic detection and segmentation of tissues or organs and the assessment of their pathologies. For this purpose, the achievements of radiomics are particularly useful, including image-texture analyses. Various machine learning methods are also useful for exploring medical imaging data and are widely used in medical diagnostic support systems. Deep learning algorithms play a particularly important role in this respect. Recently, dynamic developments have been achieved in the field of deep learning algorithms, and their effectiveness has been confirmed in numerous applications of medical image analyses of various modalities.

Background: Temporomandibular joint disorder (TMD) is a common medical condition. Cone beam computed tomography (CBCT) is effective in assessing TMD-related bone changes, but image noise may impair diagnosis. Emerging deep learning reconstruction algorithms (DLRs) could minimize noise and improve CBCT image clarity. This study compares standard and deep learning-enhanced CBCT images for image quality in detecting osteoarthritis-related degeneration in TMJs (temporomandibular joints). This study analyzed CBCT images of patients with suspected temporomandibular joint degenerative joint disease (TMJ DJD). Methods: The DLM reconstructions were performed with ClariCT.AI software. Image quality was evaluated objectively via CNR in target areas and subjectively by two experts using a five-point scale. Both readers also assessed TMJ DJD lesions. The study involved 50 patients with a mean age of 28.29 years. Results: Objective analysis revealed a significantly better image quality in DLM reconstructions (CNR levels; p < 0.001). Subjective assessment showed high inter-reader agreement (κ = 0.805) but no significant difference in image quality between the reconstruction types (p = 0.055). Lesion counts were not significantly correlated with the reconstruction type (p > 0.05). Conclusions: The analyzed DLM reconstruction notably enhanced the objective image quality in TMJ CBCT images but did not significantly alter the subjective quality or DJD lesion diagnosis. However, the readers favored DLM images, indicating the potential for better TMD diagnosis with CBCT, meriting more study. Full article

Abstract

A medial meniscus posterior root tear (MMPRT) contributes to knee joint degeneration. Arthroscopic transtibial pullout repair (ATPR) may restore biomechanical integrity for load transmission. However, degeneration persists after ATPR in certain patients, particularly those with preoperative subchondral insufficiency fracture of the knee (SIFK). [...] Read more.

A medial meniscus posterior root tear (MMPRT) contributes to knee joint degeneration. Arthroscopic transtibial pullout repair (ATPR) may restore biomechanical integrity for load transmission. However, degeneration persists after ATPR in certain patients, particularly those with preoperative subchondral insufficiency fracture of the knee (SIFK). We explored the relationship between preoperative SIFK and osteoarthritis (OA) progression in retrospectively enrolled patients who were diagnosed as having an MMPRT and had received ATPR within a single institute. Based on their preoperative magnetic resonance imaging (MRI), these patients were then categorized into SIFK and non-SIFK groups. OA progression was evaluated by determining Kellgren–Lawrence (KL) grade changes and preoperative and postoperative median joint widths. SIFK characteristics were quantified using Image J (Version 1.52a). Both groups exhibited significant post-ATPR changes in medial knee joint widths. The SIFK group demonstrated significant KL grade changes (p < 0.0001). A larger SIFK size in the tibia and a greater lesion-to-tibia length ratio in the coronal view were positively correlated with more significant KL grade changes (p = 0.008 and 0.002, respectively). Thus, preoperative SIFK in patients with an MMPRT was associated with knee OA progression. Moreover, a positive correlation was observed between SIFK lesion characteristics and knee OA progression.
