Purpose: Cardiac diseases is and will be a leading cause of death in the world. Locating and measuring extent of infarct region by local parameters can used as a computer aided diagnostic tool in cardiac imaging ...

In the current radiological practice, there is no gold standard for the diagnosis of dementia and we are dependent on qualitative visual assessment of images such as visual scores of atrophy. To increase the accuracy of ...

Background: Intravoxel incoherent motion is a diffusion weighted imaging method which can characterize the relation between signal intensity and b value. Regarding to this bi-exponential model, IVIM would separate ...

Background and Objective: There is evidence of association between aging and increase in the normal limit of the common bile duct (CBD) diameter. As aging is a documented risk factor for atherosclerosis, and the ...

Objective: The present study aimed to compare the qualitative (time intensity curve analysis), the semi-quantitative and the quantitative multiphase 3T dynamic contrast-enhanced (DCE) MRI parameters as predictors of ...

Introduction: Living donor renal transplantation has become major treatment for patients with end-stage renal disease. Preoperative evaluation of potential renal donors is crucial for selecting proper donors and the ...

Purpose: To evaluate differences in fraction of particles shunting to the lungs and possible factors contributing to these differences across patients undergoing Tc-99m MAA mapping prior to Selective Internal Radiation ...

Background: Multiple Sclerosis is a demyelinating disease which involve almost 2.5 million people all around the world. There are different MR pulse sequences which are used to detect MS plaques. This study is intended ...

Background: Our aim was to detect the performance characteristics of multiparametric magnetic resonance imaging (mp-MRI) in patients with clinical suspicion, or previous diagnosis, of prostate cancer. The study sought ...

Background: The conventional radiological procedures are a significant source of radiation to the population. Although patients can benefit from medically indicated x-ray procedures, their use involves some potential ...

Introduction: Percutaneous liver biopsy is a common procedure worldwide. It is now used as the reference standard for diagnosing most parenchymal liver disease. Pain is a common complication after liver biopsy. It ...

Background: The radiation damages could be repaired, but some of these damages which fail to repair could result in cell death or mutation. The induced damages could be modulated by radioprotectors. Cimetidine and ...

Introduction: Gliomas are the most common malignant primary brain tumors. Magnetic resonance spectroscopy has been used for grading these lesions. It has been shown that the amount of free tumor lipid metabolites is ...

Background: Vascular access has become a very important aspect of care for neonates. The use of peripherally inserted central venous catheters (PICCs) has become common in recent years. Therefore, the aim of study ...

Background: Meningioma, the most frequent intracranial, extra-axial tumor, constitutes %13-26 of all intracranial neoplasms. Less than %10 of all meningiomas account for grade II or III (atypical-anaplastic) based ...

Studies have demonstrated that increased brain iron concentration is associated with Parkinson's disease. Parkinson's is the most common degenerative neurological disorder after Alzheimer's disease. Many studies have shown ...

Background / Objectives: Intrauterine growth restriction (IUGR) is defined on the basis of a weight below the 10th percentile for gestational age. placental insufficiency is a major cause of IUGR. Currently, diagnosis ...

Introduction: The stroke disease leads to some problems in normal brain diffusion. Thus, DWI can be used in the early diagnosis of this disease, especially in acute phase. Acquired ADC maps from DWI show the water ...

Introduction: Magnetic resonance imaging (MRI) is the gold standard imaging technique for identification of demyelinating lesions such as Multiple Sclerosis (MS). The Consortium of MS Centers Consensus (CMSC) Guidelines ...

Introduction: All radiology centers use ionizing radiation. Among the various instruments used to measure radiation doses, thermoluminescence dosimeters (TLDs) and filmbaj are most widely used. Using the ...
