The use of automatic measurement methods based on artificial intelligence can overcome many drawbacks of the usual method and can significantly save the time of the radiologist. AIM: to analyze the accuracy, advantages and disadvantages of a newly developed AI program for automatic diagnosis of scoliosis and measurement of Cobb’s angle on frontal radiographs. Methods: 112 digital radiographs were used to test the agreement of Cobb’s angle measurements between the new automatic method and the radiologist using Blant-Altman method on Microsoft Excel. A limited clinical accuracy test was also conducted using 120 radiographs. The accuracy of the system in defining the grade of scoliosis was evaluated by calculating sensitivity; specificity; accuracy; and area under the ROC curve (ROC AUC). RESULTS: The agreement of Cobb’s angle measurement between the system and the radiologist was found mostly in scoliosis with grades 1 and 2. Only 2.8% of the results were found to be unsatisfying with an angle variability of more than 5°. Diagnostic accuracy metrics of the limited clinical trial in Mariinsky city hospital had also proved the reliability of the system, with sensitivity = 0.97; specificity = 0.88; accuracy (general validity) = 0.93; area under the ROC curve (ROC AUC) = 0.93. CONCLUSION: Overall, the AI program can automatically and accurately define the grade of scoliosis and measure the angles of spinal curvatures on frontal radiographs.","PeriodicalId":34831,"journal":{"name":"Digital Diagnostics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141821026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic resonance imaging is the method of choice for the diagnosis of articular cartilage defects [1].

The study was approved by the local ethical committee of International Tomography Center (Novosibirsk, Russia). Exclusion criteria: exacerbation stage of comorbid diseases, knee joint osteoarthritis of stages 3–4. The main group consisted of patients with signs of chondromalacia; the group with initial degenerative changes — of patients with local areas of thinning and/or changes in the signaling characteristics of articular cartilage with minor/no degenerative changes of the joint. The control group consisted of patients without changes in cartilage signaling characteristics, traumatic and degenerative changes of the knee joint. The study of the knee joint was performed on a Philips INGENIA magnetic resonance tomograph (1.5T intensity) using the routine protocol: T2-weighted images, PD-SPAIR, PD-weighted images, T1-weighted images and T2 mapping technique with calculation of the T2-relaxation time of the cartilage tissue.

{"title":"Application of the modernized wavelet transform to highlight the dynamics of changes in the duration of intervals during electrocardiogram diagnostics","authors":"Charif Alali, Dmitry A. Balalkin","doi":"10.17816/dd626185","DOIUrl":"https://doi.org/10.17816/dd626185","url":null,"abstract":"BACKGROUND: Cardiovascular diseases represent the leading cause of mortality worldwide [1]. A significant proportion of medical diagnoses are based on the evaluation of characteristic points in the electrocardiographic signal. For example, two important time intervals are P–R and Q–T, which have a significant impact on the patient’s health status [2]. \u0000However, the detection of minimal changes in amplitudes and intervals between waves over time is challenging through visual inspection alone. The difficulty is compounded by the lack of a clear-cut rule for determining the beginning and end of the Q–T interval, and the fact that the duration of the intervals varies with each heartbeat [3]. \u0000AIM: The study aimed to develop an algorithm to highlight the dynamics of interval duration changes when analyzing electrocardiographic signals. \u0000MATERIALS AND METHODS: The wavelet transform serves as a valuable analytical tool. Its ability to decompose signals into well-localized basis functions makes it well suited to distinguish electrocardiographic waves from noise [4]. Furthermore, its ability to change the scale allows for the detection of various local inhomogeneities in the electrocardiographic signal, as well as their durations. \u0000One of the main problems in using wavelet transform is the choice of the mother function. In this paper, we propose to use Hermite transform [5], due to which a mother function of arbitrary shape can be designed, which improves the detection efficiency. Moreover, the Hermite transform can be applied to the authentic electrocardiographic signal recording, ensuring the retention of the distinctive attributes of the patient’s signal. \u0000RESULTS: The result of the algorithm is a set of rhythmograms, each of which traces the changes over time of intervals of the electrocardiographic signal, for example, P–R or Q–T. The rhythmogram is a stochastic characteristic that allows estimation of the dispersion of Q–T intervals even during short time intervals and when changing the level of physical activity. This is why, by applying the statistical apparatus, it is possible to quantify the diagnostic efficiency of the proposed processing algorithm. \u0000CONCLUSIONS: The paper presents the main conclusions of the algorithm and the results of processing model electrocardiographic signals.","PeriodicalId":34831,"journal":{"name":"Digital Diagnostics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mashchenko","doi":"10.17816/dd626016","DOIUrl":"https://doi.org/10.17816/dd626016","url":null,"abstract":"BACKGROUND: One of the principal indications of placenta accreta is pathological vascular remodeling in the region of the placental site. This phenomenon, which may result from various mechanisms, can give rise to significant blood loss in women undergoing cesarean section [2]. \u0000AIM: The study aims to evaluate the correlation between different types of abnormal hypervascularization observed on pelvic magnetic resonance imaging in pregnant women with placenta accreta and blood loss during surgical delivery by cesarean section. \u0000MATERIALS AND METHODS: A total of 224 patients in the second and third trimesters of pregnancy with placenta previa and placenta accreta were examined. This was confirmed by ultrasound and magnetic resonance imaging, and subsequently by histopathologic examination. The mean age of the patients was 34.8±0.41 years (M±SE, p 0.05). Magnetic resonance imaging was conducted in accordance with a three-stage protocol on tomographs with magnetic field strengths of 1.5 and 3 Tesla. The diagnosis of placenta accreta was based on 11 signs, as outlined in the joint consensus statement of the Society of Abdominal Radiology and the European Society of Urogenital Radiology [1]. In addition, signs of hypervascularization were evaluated, including intrauterine (retroplacental, intramural, and subserosal) and extrauterine (parametrial, paracervical, and uterine-ovarian anastomosis zone) regions. The diagnostic criteria for hypervascularization were defined as an increase in the diameter of vessels, as indicated by areas of magnetic resonance signal dropout, their pronounced tortuosity, and their location in the corresponding anatomical regions relative to the uterus. Blood loss during labor was assessed in five categories: 1000 mL, 1000–1500 mL, 1500–2000 mL, 2000–3000 mL, and 3000 mL [3]. The correlation between variables was assessed using linear regression and Pearson’s correlation coefficient (r) and one-way analysis of variance. Differences were considered statistically significant at p 0.05. \u0000RESULTS: According to the data of correlation analysis, the formation of anterior (r=0.3591, p 0.0001) and lateral (r=0.2799, p 0.0001) parametrial vascular collateralization, as well as utero-ovarian anastomosis (r=0.1369, p=0.0407) had the most significant effect on the severity of postpartum hemorrhage. There was no statistically significant effect of retroplacental hypervascularization on the increase in blood loss volume (r=–0.01611, p=0.6051). \u0000CONCLUSIONS: The study demonstrated that patterns of abnormal vascular remodeling in the placental site can be clearly identified by magnetic resonance imaging and used as a predictor of severe hemorrhage. Pregnant women with such MRI findings should be referred to a level 3 perinatal center to ensure adequate control of increased risks of obstetric hemorrhage during operative delivery.","PeriodicalId":34831,"journal":{"name":"Digital Diagnostics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141681051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
