[0030] Primary trigeminal neuralgia (PTN) is a common neuropathic pain disorder characterized by recurrent, severe pain in the trigeminal nerve distribution area on the affected side of the face. The prevalence of trigeminal neuralgia is approximately 0.16% to 0.3%, with an annual incidence of approximately 12.6 to 27.0 cases per 100,000 people. The incidence rate in women is three times higher than in men, and the average age of onset is generally between 53 and 57 years.
[0031] PTN accounts for 75% of all trigeminal neuralgia (TN) cases. Compared to secondary TN, the etiology of PTN is not fully understood, and specific diagnostic methods are lacking, making diagnosis extremely challenging. Secondary TN, on the other hand, is often accompanied by other well-recognized secondary factors such as tumors, inflammation, multiple sclerosis, and viral infections, making diagnosis relatively straightforward. The currently prevailing neurovascular compression (NVC) theory does not fully explain PTN, as not all PTN patients demonstrate clear imaging findings. Therefore, finding an objective, quantitative, and accurate method for diagnosing TN is crucial.
[0032] Based on the above technical problems, an embodiment of the present application provides a method for predicting the risk of trigeminal neuralgia, which obtains an MRI image by performing magnetic resonance imaging on the target area of the patient, and obtains multiple image group feature data by extracting and screening the image group features in the MRI image. The multiple image group feature data and multiple clinical data are processed based on a joint scoring model to obtain a risk prediction score for whether the trigeminal neuralgia disease has the risk of trigeminal neuralgia.
[0033] This embodiment provides an automated auxiliary diagnosis method for trigeminal neuralgia, which uses MRI images and multiple clinical indicators to establish a joint evaluation model. Based on this joint evaluation model, a predictive score is given for the incidence probability and severity of trigeminal neuralgia, with a high detection rate and accuracy.
[0034] For more information on this risk prediction method, see Figure 1 , including the following steps:
[0035] Step S11: Acquire clinical data of the patient to be diagnosed and image group feature data of the target area of the patient to be diagnosed.
[0036] In this embodiment, this method adopts a combined prediction method to predict trigeminal neuralgia, especially primary trigeminal neuralgia, especially to predict the probability and severity of trigeminal neuralgia. The logic of the combined prediction method is to obtain the score corresponding to each indicator based on the nomogram through the prediction model, and then obtain the total score. The total score is used to determine the possibility of trigeminal neuralgia.
[0037] The indicators in this embodiment include clinical data and MRI image group feature data, wherein the image group feature data is image feature data of a neural MRI sequence and a vascular MRI sequence, and the risk prediction model is a nomogram model.
[0038] Specifically, the clinical data in the indicators include the degree of neurovascular compression, the weight of the neurovascular compression site, the vertical height of the trigeminal nerve cistern segment, the enlarged cross-sectional area of the trigeminal nerve cistern segment, and the nerve-pons angle.
[0039] Among them, the multiple clinical data in this implementation were obtained by screening clinical data that appeared in the clinic. The specific screening method was to integrate the initial clinical data, including the degree of vascular compression (divided into four levels: away from, contact, compression, and nerve pushing), the location of vascular compression or proximity to the nerve (proximal and distal), the thickness of the nerve's adjacent blood vessels, the maximum transverse diameter, maximum diameter, and maximum cross-sectional area of the Merkel cavity, the maximum cross-sectional area (or thickness) of the trigeminal nerve cistern segment, the height difference between the highest and lowest points of the trigeminal nerve cistern segment, the area of the prepontine cistern, APR, TPA, and ATN, a total of 13 clinical characteristics. Then, several clinical characteristics associated with symptomatic nerves were identified through univariate analysis, including the maximum cross-sectional area of the trigeminal nerve cistern segment, the vertical height of the trigeminal nerve cistern segment, ATN, APR, TPA, the location of vascular compression of the nerve (adjacent), and the degree of vascular compression (P < 0.05).
[0040] The image group feature data in this embodiment includes first-order features, neighborhood grayscale difference matrix busyness, multiple grayscale co-occurrence matrix features, multiple grayscale region matrix features, and grayscale correlation matrix dependent variance.
[0041] Among them, the first-order minimum value includes the first-order minimum value, the first-order tenth percentile, the first-order energy value, the first-order ninetieth percentile, the first-order total energy value, the first-order interquartile range, the first-order skewness value, the first-order range, and the first-order mean absolute deviation; multiple grayscale co-occurrence matrix features include differential entropy, inverse variance, correlation, cluster prominence, and autocorrelation; multiple grayscale size area matrix features include large area high grayscale emphasis, normalized grayscale inhomogeneity, normalized area size inhomogeneity, area percentage, and large area emphasis.
[0042] Among them, the acquisition of the above-mentioned imaging group feature data is first performed by image segmentation and region of interest extraction on the MRI image. Specifically, the ROI range of the trigeminal nerve is selected from the point where the TN enters the pons to the entrance of the Meckel cavity. Use ITK-SNAP to manually segment the ROI in the neural MRI sequence and vascular MRI sequence images layer by layer; finally, the segmentation data (mask data) of the patient examination is processed, and only the ROI on the symptomatic side is retained for TN patients. Among them, for the segmentation results of the ROI area, please refer to Figure 2 As shown, Figure 2 A is the left ROI and right ROI of the MRI nerve sequence, Figure 2 B shows the left ROI and right ROI of the MRI vascular sequence.
[0043] During the feature extraction process, DICOM images were resampled with the same pixel spacing (0.5x0.5x0.5mm). Quantile normalization was used to normalize the pixel intensity of neural and vascular MRI sequences from 0 to 512.
[0044] The radiomics toolkit was used to extract the radiomics features of each ROI, and LASSO regression was used to reduce the dimensionality of the features. Radiomics features with a weight of 0 were removed to reduce overfitting caused by high-dimensional data.
[0045] The above method is used to finally screen out multiple image group feature data and multiple clinical data in this embodiment.
[0046] Step S12: Input the clinical data and the imaging group feature data into a risk prediction model to calculate the risk value.
[0047] In this embodiment, the risk prediction model is a nomogram model. The nomogram model obtains the mapping scores corresponding to the multiple clinical data and imaging group characteristic data obtained in step S11, and obtains a total score based on the scores corresponding to each indicator and imaging group characteristic data. This total score is the risk value in this embodiment, which is used to characterize the grade corresponding to the onset of trigeminal neuralgia and the degree of risk of onset.
[0048] Specifically, the neurovascular compression degree value, the neurovascular compression site weight value, the vertical height value of the trigeminal nerve cistern segment, the increased cross-sectional area value of the trigeminal nerve cistern segment and the nerve-pons angle value and the first score, second score, third score, fourth score, fifth score and sixth score corresponding to the imaging group feature data are obtained respectively, and the total score is obtained based on the first score, second score, third score, fourth score, fifth score and sixth score.
[0049] For the calculation results of this nomogram model, please refer to Figure 3, where radsocre is the overall calculated score of the image group feature data, that is, the sixth score value. The calculation of the radsocre score is based on the following formula: Radscore = -0.46*first-order minimum value -0.0008*first-order tenth percentile -0.4*first-order energy value -0.02*first-order ninetieth percentile +8.32*first-order total energy value -0.000082*first-order interquartile range -0.000051*first-order skewness value -1.25*first-order range +0.0036*first-order mean absolute deviation +0.000063*neighborhood grayscale difference matrix busyness +0.000091*grayscale co-occurrence matrix difference entropy +1.5650*grayscale Degree co-occurrence matrix inverse variance +1.4762*Gray-level co-occurrence matrix correlation +0.377*Gray-level co-occurrence matrix cluster prominence +2.3012*Gray-level co-occurrence matrix autocorrelation +0.4389*Gray-level size area matrix large area high gray-level emphasis +0.1537*Gray-level size area matrix normalized gray-level unevenness +0.00794*Gray-level size area matrix normalized area size unevenness +0.1253*Gray-level size area matrix area percentage +0.2699*Gray-level size area matrix large area emphasis +0.0055*Gray-level correlation matrix dependent variance.
[0050] The specific calculation process of the nomogram in this embodiment can be directly referred to Figure 3 As shown, this can be achieved by using the calculation logic of the nomogram, which will not be described in detail in this embodiment.
[0051] In summary, in this embodiment, by combining the above-mentioned multiple groups of indicators, the possibility and severity of trigeminal neuralgia can be effectively evaluated in advance, and score data reflecting trigeminal neuralgia can be obtained. The probability and severity of trigeminal neuralgia can be determined more intuitively through this score data, thereby realizing the overall automated prediction of trigeminal neuralgia.
