Comparison of Preprocessing Techniques for Dental Image Analysis
Authors: Arockia Sukanya, Kamalanand Krishnamurthy and Thayumanavan BalakrishnanVarious dental disorders, such as lesions, masses, carries, etc. may affect the human dental structure. Dental radiography is a technique, which passes X-rays through dental structures and records the radiographic images. These radiographic images are used to analyze the disorders present in the human teeth. Preprocessing is a primary step to enhance the radiographic images for further segmentation and classification of i Read More

Computer-aided Diagnosis of Skin Cancer: A Review
Cancer is currently one of the main health issues in the world. Among different varieties of cancers, skin cancer is the most common cancer in the world and accounts for 75% of the world's cancer. Indeed, skin cancer involves abnormal changes in the outer layer of the skin. Although most people with skin cancer recover, it is one of the major concerns of people due to its high prevalence. Most types of skin cancers grow on Read More

Melanoma Detection and Classification using Computerized Analysis of Dermoscopic Systems: A Review
Malignant melanoma is considered as one of the most deadly cancers, which has broadly increased worldwide since the last decade. In 2018, around 91,270 cases of melanoma were reported and 9,320 people died in the US. However, diagnosis at the initial stage indicates a high survival rate. The conventional diagnostic methods are expensive, inconvenient and subject to the dermatologist’s expertise as well as a highly e Read More

Review of Automated Computerized Methods for Brain Tumor Segmentation and Classification
Authors: Umaira Nazar, Muhammad A. Khan, Ikram Ullah Lali, Hong Lin, Hashim Ali, Imran Ashraf and Junaid TariqRecently, medical imaging and machine learning gained significant attention in the early detection of brain tumor. Compound structure and tumor variations, such as change of size, make brain tumor segmentation and classification a challenging task. In this review, we survey existing work on brain tumor, their stages, survival rate of patients after each stage, and computerized diagnosis methods. We discuss existing image pr Read More

Computer-aided Diagnosis of Melanoma: A Review of Existing Knowledge and Strategies
Authors: Ananjan Maiti, Biswajoy Chatterjee, Amira S. Ashour and Nilanjan DeyComputer-aided diagnosis (CAD) systems are the best alternative for immediate disclosure and diagnosis of skin diseases. Such systems comprise several image processing procedures, including segmentation, feature extraction and artificial intelligence (AI) based methods. This survey highlights different CAD methodologies for diagnosing Melanoma and related skin diseases. It has also discussed types, stages, treatmen Read More

Thermal Imaging Techniques for Breast Screening - A Survey
By Prabha S.Breast cancer is the second leading cause of cancer death among women preceded by cervix cancer. It has been reported that at the early stage of detection there is 85% chance of getting cured, whereas only 10% chance at later stage diagnosis. The current screening modalities are expensive, they have intricate imaging measures and they are unhealthy due to radiation exposure. Therefore, a screening tool that is n Read More

Role of General Adversarial Networks in Mammogram Analysis: A Review
Authors: Annapoorani Gopal, Lathaselvi Gandhimaruthian and Javid AliThe Deep Neural Networks have gained prominence in the biomedical domain, becoming the most commonly used networks after machine learning technology. Mammograms can be used to detect breast cancers with high precision with the help of Convolutional Neural Network (CNN) which is deep learning technology. An exhaustive labeled data is required to train the CNN from scratch. This can be overcome by deplo Read More

Black Hole Sign on Noncontrast Computed Tomography in Predicting Hematoma Expansion in Patients with Intracerebral Hemorrhage: A Meta-analysis
Authors: Yilin Chen, Lu Tian, Longlun Wang, Yong Qin and Jinhua CaiBackground: Black hole sign represents a novel imaging marker for predicting hematoma expansion (HE) in patients with intracerebral hemorrhage (ICH). Several previous studies have reported the accuracy of black hole sign in predicting HE, but the accuracy was variable. We performed a meta-analysis to systematically assess the accuracy of black hole sign in predicting HE in patients with ICH. Methods: A systematic searc Read More

Evaluation of Contrast-enhanced Transcranial Color-coded Duplex Sonography (CE-TCCD) Applied in Stroke Patients with Intracranial Collateral Circulation
More LessBackground and Introduction: Collateral circulation is very crucial for the prognosis of stroke patients. Transcranial color-coded duplexsonography (TCCD) is used widely to evaluate the intracranial arterial blood flow. However, approximately 20% - 30% of the patients with cerebral infarction cannot be detected via TCCD due to the interruption of thickened temporal bones. We assessed the diagnostic efficacy of contrast-enha Read More

Automatic Analysis of ACR Phantom Images in MRI
Authors: Ines B. Alaya and Mokhtar MarsBackground: Quality Assurance (QA) of Magnetic Resonance Imaging (MRI) system is an essential step to avoid problems in diagnosis when image quality is low. It is considered a patient safety issue. The accreditation program of the American College of Radiology (ACR) includes a standardized image quality measurement protocol. However, it has been shown that human testing by visual inspection is not objective and not repro Read More

Breast Cancer Diagnosis in Digital Mammography Images Using Automatic Detection for the Region of Interest
Authors: Saleem Z. Ramadan and Mahmoud El-BannaBackground: One of the early screening methods of breast cancer that is still used today is mammogram due to its low cost. Unfortunately, this low cost accompanied with low performance rate also. Methods: The low performance rate in mammograms is associated with low capability in determining the best region from which the features are extracted. Therefore, we offer an automatic method to detect the Region of Int Read More

Cone Beam CT Evaluation of Maxillary Sinus Floor and Alveolar Crest Anatomy for the Safe Placement of Implants
Authors: Başak Kuşakçi Şeker, Kaan Orhan, Emre Şeker, Gülbahar Ustaoğlu, Oğuz Ozan and Nilsun BağişBackground: Alveolar bone height in the posterior maxillary region is very important and critical for dental implant planning and placement. Objectives: This study aimed to evaluate the anatomy of the maxillary sinus floor in relation to the alveolar crest and to determine variations in the vertical measurements between the maxillary sinus floor and the alveolar bone crest tip in the posterior edentulous maxilla with the use Read More

A Sleeping rs-fMRI Study of Preschool Children with Autism Spectrum Disorders
Authors: Xiaomeng Li, Longlun Wang, Bin Qin, Yun Zhang, Zhiming Zhou, Yong Qin, Guangcheng Bao, Jie Huang and Jinhua CaiObjectives: The brain functional network of autism spectrum disorders (ASDs) in the earlier stages of life has been almost unknown due to difficulties in obtaining a resting-state functional magnetic resonance imaging (rs-fMRI). This study aimed to perform rs-MRI under a sedated sleep state and reveal possible alterations in the brain functional network. Methods: Rs-fMRI was performed in a group of preschool children ( Read More

Multiparametric MRI Evaluation of Developmental Venous Anomalies in the Brain: Association with Signal Changes on FLAIR in Patients with Multiple Sclerosis
Authors: Ergin Sagtas, Serkan Guneyli, Dincer A. Akyilmaz, Huseyin Gokhan Yavas, Pinar Cakmak and Furkan UfukBackground: Developmental venous anomalies (DVAs) can be determined on magnetic resonance imaging (MRI), and they may be associated with multiple sclerosis (MS) lesions. Purpose: The objective was to evaluate the MRI findings of DVAs in the brain, to compare the prevalence of them between MS patients and control subjects, and to investigate the correlation of DVA-associated fluid-attenuated inversion recovery (FLAI Read More
