background : magnetic resonance imaging of the breast is becoming a useful adjunct to mammography and sonography for the detection of breast lesions. however, it is not yet accepted as a routine examination for all breast cancer patients due to the lack of data regarding whether breast magnetic resonance imaging impacts recurrence or survival. this trial examines the use of magnetic resonance i...

background hepatic fibrosis is a typical complication of chronic liver diseases resulting in cirrhosis that remains a major public health problem worldwide. liver biopsy is currently the gold standard for diagnosing and staging hepatic fibrosis. percutaneous liver biopsy; however, is an invasive procedure with risks of complications. therefore, there is need for alternative non-invasive techniq...

Magnetic resonance (MR) acoustic scanner noise may negatively affect the performanceof functional magnetic resonance imaging (±MRI), a problem that worsens at the higher field strengths proposed to enhance ±MRI. We present an overview of the current knowledge on theeffects of confounding acoustic MR noise in fMRI experiments. The principles and effectivenessof various methods to red...

Proton magnetic resonance imaging (MRI) examinations were performed in six patients with seven acoustic neuromas, and the results were compared with conventional tomography of the internal auditory canals, contrast-enhanced computed tomography (CT), and air CT cisternography. All tumors were identified with MRI. The three largest tumors (greater than 1 cm diameter) looked similar to the tumors ...

background: early diagnosis of brain tumors has significant effect on the treatment process. brain metastatic tumors are usually diagnosed following the neurological symptoms in patients or incidentally after computerized tomography (ct) scan and magnetic resonance imaging (mri) requests of the brain. objectives: implementation of a new method for being informed about the origin of brain tumors...

nowadays brain tumors remain as a significant cause of morbidity and mortality and are often treatment refractory. the grading of brain tumor has an important implication in clinical management. currently, magnetic resonance spectroscopy (mrs) is an important modality in evaluating and grading brain tumors. the aim of this study is  evaluation of metabolites in the differentiation of brain tumo...

background: so far, non-invasive diagnostic approaches such as ultrasound, magnetic resonance imaging, or blood tests do not have sufficient diagnostic power for endometriosis disease. lack of a non-invasive diagnostic test contributes to the long delay between onset of symptoms and diagnosis of endometriosis. objective: the present study focuses on the identification of predictive biomarkers i...
