Intelligent Decision Support System for Differential Diagnosis of Chronic Odontogenic Rhinosinusitis Based on U-Net Segmentation

Abstract

The share of chronic odontogenic rhinosinusitis is 40% among all chronic rhinosinusitis. Using automated information systems for differential diagnosis will improve the efficiency of decision-making by doctors in diagnosing chronic odontogenic rhinosinusitis. Therefore, this study aimed to develop an intelligent decision support system for the differential diagnosis of chronic odontogenic rhinosinusitis based on computer vision methods. A dataset was collected and processed, including 162 MSCT images. A deep learning model for image segmentation was developed. A 23 convolutional layer U-Net network architecture has been used for the segmentation of multi-spiral computed tomography (MSCT) data with odontogenic maxillary sinusitis. The proposed model is implemented in such a way that each pair of repeated 3 × 3 convolutions layers is followed by an Exponential Linear Unit instead of a Rectified Linear Unit as an activation function. The model showed an accuracy of 90.09%. To develop a decision support system, an intelligent chatbot allows the user to conduct an automated patient survey and collect patient examination data from several doctors of various profiles. The intelligent information system proposed in this study made it possible to combine an image processing model with a patient interview and examination data, improving physician decision-making efficiency in the differential diagnosis of Chronic Odontogenic Rhinosinusitis. The proposed solution is the first comprehensive solution in this area.

Fluorescence visualization for cancer DETECTION: EXPERIENCE and perspectives

“…The article highlights that conventional fluorescence-guided surgery primarily utilizes the first window (NIR-I, 700–900 nm), characterized by a limited tissue penetration depth ranging from 1 to 6 mm [ [87] , [88] , [89] ]. Conversely, the second near-infrared window (NIR-II, 1000–1700 nm) significantly surpasses the constraints imposed by tissue absorption, autofluorescence, and photon scattering, enabling profound tissue penetration (up to 20 mm), micron-scale spatial resolution, intelligent decision-making with U-Net Segmentation, and a high tumor-to-normal tissue (T/NT) ratio exceeding 190 [ [90] , [91] , [92] , [93] , [94] , [95] , [96] , [97] ]. These features hold promise for enhancing T/NT ratio and delineating tumor margins more precisely, thereby facilitating more accurate tumor resection.…”

A Novel Machine Learning Model for Predicting Orthodontic Treatment Duration

“…AI is a broad term for the technological systems that gather large data samples and export information that is used to help or improve a human's decision-making process [10]. In recent years, there has been a remarkable surge in the application of AI and ML techniques within the field of dentistry [10][11][12], including the specialized domain of orthodontics [13][14][15][16][17][18][19][20][21][22][23][24][25]. These technologies have been harnessed to analyze radiographic images [23,[26][27][28][29][30][31][32][33], predict growth [24,34,35], optimize orthodontic treatment decision-making processes [13][14][15][16][17][19][20][21][22]25,36].…”
