Background: Nano-Metal-Organic Frameworks (NMOFs) have stable pores in their assembly. In the recent era, these have been used in biomedicine, magnetic and electronic devices and sensors. MOFs also have a potential concern in biomedical applications, a new substitute of therapeutic and/or diagnostic materials, among others. Initially, NMOFs have been used as delivery vehicles for imaging contrast agents Read More

Background: “Computer Aided Diagnosis (CAD)” methods are today considered an important means to facilitate and speed-up the work of medical experts, namely in detection, segmentation, and classification of both healthy and pathologic structures in medical image data. Discussion: This paper provides an overview of such recently published methods aimed at analysing metastatic lesions in the spine using CT imaging. Mo Read More

Background: Cardiac Magnetic Resonance (CMR) represents one of the most valuable modalities for the non-invasive diagnosis and characterization of cardiovascular diseases. CMR proton imaging is the state-of-the-art diagnostic tool for myocardial morphology and function evaluation. CMR Spectroscopy is a very powerful tool for exploration of tissue components and metabolism of the myocardium, through Read More

Background: Knee bone diseases are rare but might be highly destructive. Magnetic Resonance Imaging (MRI) is the main approach to identify knee cancer and its treatment. Normally, the knee cancers are detected with the help of different MRI analysis techniques and later image analysis strategies assess these images. Discussion: Computer-based medical image analysis is getting researcher's interest due to its advantage Read More

Background: ‘Sella turcica’ was first described in 1543. The “De humani corporis fabrica” is the name of a book by Andreas Vesalius that first described the ‘sella turcica’. After this date, it was called the ‘sella ephippi’, ‘sphenoidis sella’, or ‘sella equine’. In 1627, the famous anatomist Adrianus Spigelius developed the current definition of the term. Discussion: The Ottoman military power was at its highest level and a se Read More

Objectives: The objectives of this study were to: 1) compare the size and T2 signal intensity of the trigeminal nerves on the symptomatic side and asymptomatic side of the patients with idiopathic trigeminal neuralgia and to correlate these morphological findings with each other in order to assess whether Magnetic Resonance Imaging (MRI) can provide evidence of microstructural changes in the affected trigeminal nerve th Read More

Background: Fine needle biopsies are used to diagnose thyroid cancer. Nevertheless most thyroid nodules are benign so FNA is performed too often. It is very important to recognize which echographic features can help to predict benignity and avoid unnecessary biopsies. Purpose: To prospectively evaluate several ultrasonographic patterns, and the presence of comet tail artifacts, for predicting thyroid nodule benignit Read More

Background: Dynamic Magnetic Resonance Imaging (MRI) can be used to diagnose organs' motion, so it is useful and has been used widely. Reconstructing dynamic MRI from undersampled measurements can accelerate the imaging speed, this has attracted the attention of many researchers. For dynamic MRI, there is much global and local correlation in spatial and temporal dimensions, and if the spatial and temp Read More

Objective: The present study was aimed at investigating the correlation of MRI characteristics of Cerebral Palsy (CP) pediatric patients with their gestational age, type of CP and Gross Motor Function Classification System (GMFCS). Methods: 120 cases of children with cerebral palsy admitted to our hospital from May 2015 to May 2016 were selected as study subjects. MRI data were observed and the correlation of MRI characteri Read More

Background: For the cerebrovascular Digital Subtraction Angiography (DSA), how to restrain the patient motion artifact to improve the quality of subtraction image has an important effect on the clinical diagnosis. Methods: Currently, image registration is the main way to extract the blood vessels. However, there is usually massive calculation in the registration process. And it is usually only suitable for simple rigid motion ar Read More

Introduction: We present in this paper an automatic detection system of brain aneurysms in Digital Subtraction Angiography (DSA) images. Methods: The approach proposed here relies on two main steps: A region-based segmentation using the Otsu method is first employed in order to extract the vascular structure. Then a combination of the Zernike moments and MSER detector is used to detect aneurysms. Result: In o Read More

Background: This study does the qualitative analysis of segmentation technique with compression and authentication to provide improved and advanced e–health care system. This study addresses three main problems of brain tumor detection, one is to find the region of interest, second is to authenticate patient information and third is to minimize memory space for a large dataset of medical images. Methods: The propose Read More

Objectives: We retrospectively investigated the relationship between olfactory fossae depth, septal deviation angle, paranasal sinuses and the distance between infraorbital foramens (IOFs). Methods: Computerized Tomography (CT) images of 315 adult subjects were used. Paranasal sinus dimensions; Keros classification of olfactory fossae, length of Crista Galli (CG), the distance between IOFs (ZP), The distance between inf Read More

Background: Cone-beam Computed Tomography (CBCT) scans obtained with larger field of view let us see various incidental findings, anatomical variations and pathologies, like intracranial and soft tissue calcifications. Objective: The purpose of this retrospective study was to determine the prevalence of intracranial and soft tissue calcifications via CBCT. Methods: Full volume (maxillofacial region) scans of 290 patients achiev Read More

Objectives: In this study, Digital Infrared Thermal Imaging (DITI) was designed based on a noninvasive system that could display and detect the relative temperature variations in patients suffering from thyroid nodules especially nonpalpables. Methods: In this prospective clinical trial, Infrared Thermal Camera (IRC) was used alternative to conventional clinical thermometers. 32 patients confirmed with thyroid nodules and volun Read More

Background: T1, T2 and PD weighted images are the three bands of magnetic resonance image and they provide complementary information of the structure of the part being imaged. It is more useful for diagnosis and analysis if they are fused into MRI triplet. Discussion: This paper proposes a novel fusion method using Selective Frequency Localization Contourlet Transform to combine these three bands into one. Conclusion: Read More
