Population of aged people is on the rise worldwide, thanks to the advances in medicine, which enhanced lifespan. However, this increased lifespan came with a price, that is, aging associated diseases, of which diseases affecting central nervous system, in particular, stroke, Alzheimer's disease, Huntington's disease etc., are predominant. Inasmuch as intervention and access to brain is not always possible by invasive techniques, i Read More

Recent advances in the treatment of cerebral gliomas have increased the demand for diagnosis by means of neuroimaging in order to assist in treatment planning and prognosis. Advanced magnetic resonance (MR) imaging techniques, including MR spectroscopy (MRS) and MR perfusion, have proved invaluable in evaluating key pathological features of gliomas. MRS provides a broad range of information about cell membr Read More

Breast cancer is a familiar disease in the female; its effects are, however, not so much diverse in males. In females, the death rate is gradually increasing due to this disease because rarely its sign and symptoms appear at an initial phase that makes it hard to detect at an early stage. As breast cancer has developed into the rapidly growing disease among women, numerous detection methods, algorithms and new techno Read More

Hepatocellular carcinoma (HCC) is the most common primary liver cancer, which develops mostly in the setting of chronic liver disease. European Association for the Study of the Liver (EASL) and European Organization for Research and Treatment of Cancer (EORTC) prepared guidelines for screening, follow-up and diagnosis of HCC to facilitate decision making and optimize both diagnostic and therapeutic protocols. The revi Read More

Coronary CT angiography has been increasingly used to diagnose coronary artery disease with high diagnostic value achieved. For further assessment of coronary lumen stenosis, coronary CT angiography allows characterization of coronary plaques in terms of plaque morphology and composition. Coronary plaques are commonly assessed on 2D axial and multiplanar reformatted images. However, these visualization t Read More

Ultrasound is a form of mechanical waves that can traverse non-invasively through the human body up to some extent. Because of this non-invasive ability to penetrate through tissues and reflect back, ultrasound has found many applications in medicine for imaging inner organs to understand pathology and help diagnosing disease and also for therapeutic applications such as low back pain treatment, as ultrasound Read More

Non-squamous cell neoplasms (non-SCCs) are rare tumors of the oropharynx and oral cavity. They can be of many different histologic types, either benign or malignant, including in decreasing order of frequency minor salivary gland tumors, lymphoma, mesenchymal tumors, melanoma, and metastases. Unlike squamous cell carcinoma, non-SCCs could remain unidentified on clinical examination/endoscopy, because they usua Read More

Traditional pencil sketches drawn by skilled pencil sketch artists are a product of illustration based on exaggeration; there is always some amount of discrepancy between the description of eye-witnesses and depiction of the offender by the sketch artist. To overcome this difficulty, law enforcement agencies worldwide have started using composite sketches (sketches created using computer). Composite sketches have o Read More

The Purpose: The objective of this study is to explore neural correlates of Default Mode Network (DMN) regions in children with attention deficit and hyperactivity disorder (ADHD) using resting-state functional magnetic resonance imaging (rs-fMRI). Methods: The study included ten children with ADHD (aged between 9 and 16) and ten agematched controls. Four DMN regions (medial prefrontal cortex (MPFC), the posterior cingula Read More

Live video laparoscopic surgery and visual surveillance has been an important research in the past few years. Laparoscopic surgery is a modern video tracking surgical technique in which operations are performed distantly from their location through small incisions (usually 0.5-1.5 cm) in a different place in the body. The visual surveillance system starts with motion detection or tracking. This motion object detection method, Read More

Background: De-noising is the main effect produced by image compression at low compression ratios, which alters only the noise parts of images. The difference between the original and manipulated images will be less than the statistical variation when pixel values are sampled from these two images. This study develops a method that determines the quality indication in images using compression. Methods: We use the Kolmog Read More

Objective: To develop a new content-based image retrieval (CBIR) based computer-aided diagnosis (CAD) scheme to discriminate the lung nodules benign or malignant and to perform a preliminary evaluation of this CAD scheme and its robustness. Methods: Two lung nodule datasets from LIDC-IDRI lung CT database were assembled. Two nodule density related features were computed to represent each nodule. For each queried Read More

Background: Visceral bleeding caused by ruptured mycotic aneurysms, especially intracerebral hematoma, is a most serious complication. In such cases, not only surgical techniques but also a variety of modalities such as catheter-based technique is required to comprehensively treat a patient with hemorrhage-induced coagulopathy. Case Reports: We treated an infectious endocarditis (IE) patient with coagulopathy caused by r Read More
