Background: One of the primary causes of tumor death in the world is lung cancer. Lung cancer is caused by abnormalities in the lung called nodules. Different medical imaging techniques are used to detect these nodules, like Chest X-ray, Computed Tomography (CT), etc. Methods: Computer Aided Detection (CAD) in radiology provides a second opinion to radiologists in determining medical abnormalities by providin Read More

Background: Prostate cancer (PCa) is a leading dreadful cancer amid aged men in the United States. During past few decades, a number of studies have been carried out in both medical field and imaging technology for PCa detection and diagnosis. Techniques: Imaging technology-based diagnosis includes TRUS, MRI and CT at the macroscopic level and histological images at the microscopic level. Discussion: To assist novi Read More

Background: High-intensity focused ultrasound ablation is an emerging mode of therapy for benign and malignant neoplastic processes; with respect to musculoskeletal tumors, high-intensity focused ultrasound ablation has been used for palliative treatment of bone metastases and primary treatment of osteoid osteoma, synovial sarcoma, osteosarcoma, Ewing sarcoma, chondrosarcoma and giant cell bone cancer.

Background: Obesity studies involving animal models require a method for adipose tissue (AT) amount assessment. This paper focuses on the application of clinical computed tomography (CT) for abdominal obesity assessment in rats as an alternative to dedicated microtomographic systems. Additionally, the authors propose L1-L6 instead of L1-L5 region of interest (ROI) usually used for the intra-abdominal adipose ti Read More

Introduction: Vincristine sulphate is an antineoplastic agent, used in combination for the chemotherapyof B-cell neoplasm and acute lymphoblastic leukemia. Our aim was to label the vincristine with 99mTc and study it's in vivo localization in animal model, so that in future we utilize it as potential imaging agent of colon. Materials and Methods: 2mg of vincristine using stannous chloride was labeled with 99mTcO4. Its radiochemical Read More

Background: The lossy compression algorithm produces different results in various contrasts areas. Low contrast area image quality declines greater than that of high contrast regions using equal compression ratio. These results were obtained in a subjective study. The objective image quality metrics are more effective if the calculation method is more closely related to the human vision results. Methods: This study first Read More

Background: Periodically assessment of the healing process of diabetic wound is a very important task for clinicians. The quantitative analysis of wound is useful to monitor and evaluate the healing process with the intervention of drug therapies. Currently, the evaluation process focuses mainly on visual inspection, which is not accurate enough to accomplish the task. Methods: Segmentation and detection of region of the Read More

Background: The second chief foundation of enduring visual deficiency around the world is Glaucoma. Timely exposure of this disease can confine the advancement in disease progression. Calculating Cup to Disk Ratio is amongst the effective ways for figuring out the presence of glaucoma. Methods and Materials: In this paper, a Cup to Disk Ratio and Rim to Disk Ratio calculation based glaucoma detection method is propose Read More

Background: In the last few years, the number of patients suffering from Alzheimer disease has rapidly increased. This illness is a brain disease which begins at the hippocampus. Then, it spreads to the rest of the brain. It attacks especially people over the age of 65. Thus, it is necessary to develop methods to facilitate its early detection. Methods: As part of this thesis, we tried to compare two methods of classification; the Read More

Background: Multiple Sclerosis (MS) is a chronic multifactorial disease of the central nervous system, specifically characterized by inflammatory demyelination and primary neurodegeneration. Recently, a possible role for the TARDBP Ala382Thr mutation in inducing neurodegeneration in MS has been hypothesized, considering its confirmed role in other neurodegenerative diseases. The aim of the present study was to explore Read More

Background: Foramen of Huschke is anatomical anomaly in the antero-inferior aspect of external auditory canal (EAC), and is associated with pathologies. Awareness about this anomaly is clinically important. Objective: The aim of this study is to document the prevalence, laterality, and dimensions of the foramen of Huschke in the Iranian population. Methods: We retrospectively evaluated 246 cone bean computed tomo Read More

Facet joint tropism is defined as asymmetry in the facet joint angles, where one joint has a more coronal orientation than the other. Facet joint tropism is currently a subject of intense interest because it has the potential to markedly alter the motion patterns of the lumbar spine and ultimately contribute to low back pain. Objective: The aim of the study was to find out the frequency of facet tropism in the adult lumbar Read More

Background: Lung cancer is one of the leading causes of cancer-related deaths. Computer- aided diagnosis systems facilitate the radiologists in early diagnosis of pulmonary nodules. It improves the performance of the diagnostic process by providing the second opinion. Methods: A lung nodule detection method which consists of multiple steps has been proposed. At first step lung region is separated using the optimum m Read More

Background: 128-Multi-detector computerized tomography (128-MDCT) technologies make the detection of inferior phrenic arteries (IPAs) originations and traces possible. Knowing their originating and variations is very important for planning interventional and surgical procedures. Objective: To evaluate the IPAs variations in a large patient group, using 128-MDCTA. Methods: The origin, trace and branching pattern o Read More

Objective: To investigate the relationship between left or right cubital veins as intravenous contrast injection sites and the quality of enhanced CT thorax images. Materials and Methods: 332 consecutive patients who underwent contrast enhanced MDCT thorax were included. Subjects were divided into three age groups: Group 1 - <40 years, group 2 - 40-60 years, and group 3 - >60 years, who were administered contrast inj Read More

Background: Obstructive uropathy is a common public health issue that requires imaging research for providing necessary information. The data is important for determining treatment options, and may influence selective management choices. Objective: The aim of the study is to determine whether magnetic resonance urography or computerized tomography urography is the best imaging modality among patients with susp Read More

Background: Fetal echocardiography is an important method in prenatal diagnosis of Congenital Heart Disease (CHD). Fetal cardiac axis can be used as a reliable parameter in the diagnosis of CHD. The objective of this study was to discuss the abnormal fetal cardiac axis in the diagnostic value of fetal congenital heart disease. Methods: In a 3-year period, 296 women with 20 and 40 weeks' singleton gestations referred for Read More
