Background: Adipose or fat tissue measurement by MRI is a procedure that produces results similar to those of CT without exposing patients to harmful radiation. Discussion: This review explains the nature and value of adipose tissue (AT) measurements that can be performed with MRI. Conclusion: This paper attempts to provide a general understanding of the acquisition sequences and image processing methods used i Read More

Background: This article reviews the latest radiological advances in the evaluation of small bowel disease. MRI and CT have been optimized in recent years for small bowel imaging including the development of enteric agents to distend the bowel, multiplanar thin-section imaging, advanced imaging applications, and radiation dose optimization techniques. Discussion: MR enterography, with the absence of ionizing radiation ex Read More

Purpose: Numbers of computed tomography (CT) examinations are increasing, so does the number of patients exposed to ionizing radiation. Our aim was to reveal the current usage of low dose CT protocols in pulmonary nodule follow up in Gaziantep, Turkey, and what is more important to create awareness to the issue. Materials and Methods: A survey was conducted with specialists of chest diseases, thoracic surgeons and Read More

Introduction: Although obstruction of osteomeatal area was not accepted as an important factor in the pathogenesis of sinus infections for years, recent studies point out the importance of this area. For the maintenance of normal functions of paranasal sinuses, ventilation and drainage of this area is necessary. The purpose of this study was to determine the effect of anomalies of the osteomeatal area on sinus diseases. Metho Read More

Objectives: To evaluate the incremental value of diffusion weighted imaging (DWI) in addition to magnetic resonance cholangiopancreat-ography (MRCP) in diagnosing extrahepatic cholangiocarcinoma (EHCC); to determine the most appropriate b value for DWI on 3.0 T MRI. Methods: Preoperative MRI examinations were performed for 63 patients with suspected EHCC. The examinations included T2-weighted imaging, Read More

Background: Chronic pancreatitis is a progressive inflammatory disease of the pancreatic parenchyma and ductal structures. Typical MR imaging features of chronic pancreatitis include dilatation of the main pancreatic duct and irregularities of branch pancreatic ducts that can be evaluated with MRCP, loss of the normal high signal intensity of the pancreatic parenchyma on T1- weighted images, and decreased enhancement Read More

Background: The aim of this study was to compare sensitivity, specificity and accuracy of 18F-FDG PET/CT and bone scintigraphy (BS) in detection of bone metastases in breast cancer patients; particularly according to anatomical regions, CT characteristics, tumor markers and hormone receptor status. Methods: Fifty patients, who received both FDG PET/CT and BS were retrospectively analyzed. Patients’ information inclu Read More

Objectives: The purpose of the study is predicting the sites of the recurrence with PET/CT by serum CA-125 level and detecting the cut-off value of CA-125 for metastatic ovarian cancer (OC) in comparison with Fluorine-18 FDG PET/CT. Materials & Methods: For 38 patients with histological stage III-IV OC, F-18 FDG PET/CT studies (n=59) referred for suspicion of relapsing of OC were conducted. PET/CT images were assessed as po Read More

Background: We hypothesized that postoperative lymph node status would affect I-131 uptake (RIU) due to pathophysiological behavior of benign and malign thyroidal tissue. This retrospective study was designed to assess whether RIU would predict the presence of lymph node metastasis (LNM). Methods: Data for differentiated thyroid cancer patients who received postoperative I-131 therapy at our institution between 201 Read More

Background: In this paper, we propose a fully automatic intelligent computer vision based method for extracting soft tissue tumor from ultrasound images. Accurate soft tissue tumor area extraction is vital in developing reliable automatic diagnosing tool from ultrasonography. Methods: The proposed method uses many image processing algorithms including intelligent methods such as fuzzy stretching and ART2 clustering alg Read More

Background: One of the important functions of blood vessels and retinal vessels is that to extract the information in tissue of the retina for the diagnosis and treatment of various diseases such as glaucoma, hyper tension, blood pressure, cardiovascular diseases (CVD) etc. While the retinal image has to segment the blood vessels and optic disc are proposed in this novel method. Methods: Modern ophthalmology can support Read More

Background: Breast cancer is the most prevalent cancer and the second leading cause of cancer death among women. Recently, computerized methods have proved to be an extraordinary tool for radiologists for diagnosing breast cancer. In recent years, data mining techniques and image mining of digital mammography have played a significant role in diagnosing breast cancer. Mammography is considered to be an efficie Read More

Background: Blood vessel segmentation plays an important role in medical image analysis. Modern blood vessel segmentation algorithms attempts to attempts to increase patient safety by providing better diagnosis and support to more accurate medical decisions. Methods: In 3D image processing techniques leads to an emerging area, and voxel classification. Most of the voxel classification algorithms are a manual classi Read More

Background: Sphenoethmoid cells may be above the sphenoid sinus with/ or without contact to optical nerve. Although sphenoethmoid cells are theoretically considered to possibly influence the sphenoid sinus volume, we could not find any study in the literature on this issue. Aims: The aim of our study was to detect sphenoethmoid cells and measure the sphenoid sinus volume using multiplanar computerized tomography and Read More

Background: In this paper, we propose a new image denoising technique which combines two denoising approaches. Methods: The first one is a curvelet transform (cvt) based denoising technique. The second one is a two-stage image denoising by principal component analysis with local pixel grouping (LPG-PCA). This proposed technique consists at first step in applying the first approach to the noisy image in order to obtain a fi Read More

Introduction: The aim of this study was to gain an understanding of radiology professionals' awareness of, and approach towards e-portfolio use. A further aim was to monitor the effect of the training intervention, and individuals' views and attitudes towards e-portfolio usage in their continuous professional development. Materials and Methods: Questionnaires were initially distributed to 142 radiology professionals in the pre-inter Read More

Background: Ovarian torsion occurs when the ovary twists on its pedicle. This uncommon cause of acute abdomen is usually accompanied by ovarian abnormalities in postmenarchal girls. In prepubertal girls, the diagnosis is even less common. Discussion: The signs and symptoms of ovarian torsion are often vague and non-specific, especially in young girls who have difficulty explaining themselves. Ultrasound is the fir Read More

Background: Cardiac Inflammatory Myofibroblastic Tumor (IMT) is extremely rare, currently considered a tumor of borderline malignancy, with unpredictable clinical expression. IMT mimics malignant tumor in clinical presentation, imaging information, and histologic features, making diagnosis troublesome especially in the heart for its rarity. Histopathology is the gold standard for the diagnosis of cardiac IMT. Cardiova Read More
