Functional magnetic resonance imaging (fMRI) has become the most popular method for imaging of brain functions. Currently, there is a large variety of software packages for the analysis of fMRI data, each providing many features for users. Since there is no single package that can provide all the necessary analyses for the fMRI data, it is helpful to know the features of each software package. ...

background: logistic discriminant method was applied to differentiate malignant from benign in a group of patients with proved breast lesions on the basis of ultrasonic parameters. materials and methods: our database include 273 patients' ultrasonographic pictures consisting of 14 quantitative variables. the measured variables were ultrasound propagation velocity, acoustic impedence and at...

creutzfeldt-jacob disease is a prion disease which has a wide range of clinical presentations. its diagnosis is not simple and clinical manifestation along with eeg, mr imaging findings and cerebrospinal fluid (csf) analysis should be considered for a definite diagnosis. a-50-year-old woman referred with cognitive impairment, myoclonic jerks, mutism and difficulty in swallowing to our clinic. e...

ABSTRACTNeuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. It is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. Neuroimaging modalities include X-ray computed tomography (CT), magnetic resonance imaging (MRI), single photon emis...

Objective: The purpose of this study was to compare the use of cross-sectional imaging techniques verses surgery in locating parotid masses. Material and Methods: Our study was performed on patients assumed to have parotid masses from Dec 2010 to Dec 2011. Before surgery, imaging studies (Computed Tomography and Magnetic Resonance Imaging) of parotid were done. After surgery, we compared the s...
