Brain Tumor Causes, Symptoms, Diagnosis and Radiotherapy Treatment
Authors: Haarika Raghavapudi, Pankaj Singroul and V. KohilaThe strategy used for the treatment of given brain cancer is critical in determining the post effects and survival. An oncological diagnosis of tumor evaluates a range of parameters such as shape, size, volume, location and neurological complexity that define the symptomatic severity. The evaluation determines a suitable treatment approach chosen from a range of options such as surgery, chemotherapy, hormone therapy Read More

Systematic Analysis and Review of Magnetic Resonance Imaging (MRI) Reconstruction Techniques
Authors: Penta A. Kumar, Ramalingam Gunasundari and Ramalingam AarthiBackground: Magnetic Resonance Imaging (MRI) plays an important role in the field of medical diagnostic imaging as it poses non-invasive acquisition and high soft-tissue contrast. However, a huge time is needed for the MRI scanning process that results in motion artifacts, degrades image quality, misinterprets the data, and may cause discomfort to the patient. Thus, the main goal of MRI research is to accelerate dat Read More

Skeletal Survey in Multiple Myeloma: Role of Imaging
Bone disease is the hallmark of multiple myeloma. Skeletal lesions are evaluated to establish the diagnosis, to choose the therapies and also to assess the response to treatments. Due to this, imaging procedures play a key role in the management of multiple myeloma. For decades, conventional radiography has been the standard imaging modality. Subsequently, advances in the treatment of multiple myeloma have i Read More

Ultrasound Imaging of Cervical Anatomic Variants
Authors: Michael Cordes, Stephan Coerper, Torsten Kuwert and Christian SchmidkonzEmbryologic developmental variants of the thyroid and parathyroid glands may cause cervical anomalies that are detectable in ultrasound examinations of the neck. For some of these developmental variants, molecular genetic factors have been identified. Ultrasound, as the first-line imaging procedure, has proven useful in detecting clinically relevant anatomic variants. The aim of this article was to systematically sum Read More

Comparative Study of Encoder-decoder-based Convolutional Neural Networks in Cartilage Delineation from Knee Magnetic Resonance Images
Authors: Ching W. Yong, Khin Wee Lai, Belinda Pingguan Murphy and Yan Chai HumBackground: Osteoarthritis (OA) is a common degenerative joint inflammation that may lead to disability. Although OA is not lethal, this disease will remarkably affect patient’s mobility and their daily lives. Detecting OA at an early stage allows for early intervention and may slow down disease progression. Introduction: Magnetic resonance imaging is a useful technique to visualize soft tissues within the knee joint. Cartilage delin Read More

Could Computed Tomography Hounsfield Unit Values of Lumbar Vertebrae Detect Osteoporosis?
Authors: Elif Hocaoglu, Ercan Inci and Meltem VuralBackground: Dual-energy X-ray absorptiometry (DEXA) scanning has several disadvantages determining osteoporosis, especially for the degenerative spine. Introduction: This study aims to determine spinal osteoporosis in patients suffering from lumbar degenerative disease using computed tomography (CT). Methods: A total of 547 subjects that underwent DEXA and abdominal CT within a period of three months w Read More

Imaging Features of Thoracic Manifestations of Behçet’s Disease: Beyond Pulmonary Artery Involvement
Authors: Çisel Yazgan, Hakan Ertürk and Ayşenaz TaşkınBackground: Beh’s disease is a chronic multisystemic vasculitis affecting vessels of different sizes in various organs. Thoracic manifestations of the disease show a wide spectrum involving a variety of anatomic structures within the chest. However, pulmonary artery involvement is a typical manifestation of the disease that contributes significantly to mortality in patients. The study aimed to analyze CT features of thoracic m Read More

Usefulness of Contrast-enhanced Ultrasound in the Evaluation of Chronic Kidney Disease
Authors: Byoung H. Han and Sung Bin ParkBackground: Contrast-enhanced ultrasound (CEUS) can provide more improved images of renal blood flow and much more information of both macro- and microcirculation of the kidney as compared to Doppler US. Objective: To investigate the usefulness of CEUS by analyzing differences in perfusion-related parameters among the three chronic kidney disease (CKD) subgroups and the control group. Methods: Thirty-eight pat Read More

Using the Compressed Sensing Technique for Lumbar Vertebrae Imaging: Comparison with Conventional Parallel Imaging
Authors: Tianyang Gao, Zhao Lu, Fengzhe Wang, Heng Zhao, Jiazheng Wang and Shinong PanObjective: To compare conventional sensitivity encoding turbo spin-echo (SENSE-TSE) with compressed sensing plus SENSE turbo spin-echo (CS-TSE) in lumbar vertebrae magnetic resonance imaging (MRI). Methods: This retrospective study of lumbar vertebrae MRI included 600 patients; 300 patients received SENSE-TSE and 300 patients received CS-TSE. The SENSE acceleration factor was 1.4 for T1WI, 1.7 for T2WI, and 1.7 f Read More

Pituitary Volume in Patients with Primary Empty Sella and Clinical Relevance to Pituitary Hormone Secretion: A Retrospective Single Center Study
Authors: Gamze Akkus, Sinan Sözütok, Fulya Odabaş, Bilen Onan, Mehtap Evran, Barış Karagun, Murat Sert and Tamer TetikerBackground: According to neuroradiological findings, empty sella seems to be deprived of pituitary tissue in sella turcica. Changing size of the pituitary volume is closely related to the occurrence of primary empty sella. The aim of the study is to determine pituitary dysfunction in patients with partial or total primary empty sella and the significance of pituitary volume measurements in these patients. Methods: This study w Read More

The Appearance of Middle Meningeal Artery Fistulae After Willis Covered Stent for Traumatic Carotid-cavernous Fistulae: Two Case Reports
Authors: Ting Wang, Seidu A. Richard, Changwei Zhang, Xiaodong Xie and Chaohua WangIntroduction: Carotid cavernous fistulae (CCF) are rare, and they occur when there is a communication between the internal carotid artery (ICA) and cavernous sinus. These lesions are associated with blunt or penetrating traumatic injuries of the carotid arteries. We present the first cases of cavernous dural arteriovenous fistulae (cDAVF) in the middle meningeal artery (MMA) after the treatment of direct CCF in the ICA with Read More

Delayed Multiple Non-ischemic Cerebral Enhanced Lesions After Endovascular Therapy For Left Internal Carotid Aneurysm: A Case Report
Authors: Yanli Cai, Lin Huang, Jianqiang Hao, Fei Xie, Tianjin Ling and Seidu A. RichardIntroduction: Endovascular therapy (EVT) for intracranial arterial aneurysms is depicted with several complications. Very recently, delayed non-ischemic cerebral enhanced (NICE) lesions have been identified as a rare complication associated with EVT. This complication always stands a higher chance of being missed in asymptomatic patients. We report a case of multiple NICE lesions in a known chronic hepatitis B infecti Read More
