the application of magnetic resonance to diagnostic medical imaging stands as one of the great scientific achievements in the past 50 years. magnetic resonance techniques are easily applied to organs which remain stationary during the imaging procedure, such as the brain and musculoskeletal system. imaging of moving heart structures and circulating blood is considerably more difficult.   clinic...

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...

The utility of magnetic resonance imaging can often be diminished in regions and tissues that suffer from a low signal to noise ratio (SNR). This is especially the case in quantitative MRI where the quantitative parameters being measured can be easily biased by low SNR. In this study, the utility of different denoising algorithms, namely non-local means, bilateral filtering, and block-match and...

calcifying aponeurotic fibroma (caf) is a rare, benign fibroblastic tumor that typically occurs in the palms of the hands and soles of the feet, in children and adolescents. due to its infiltrative nature, this tumor can mimic malignancy on preoperative magnetic resonance imaging (mri) and has a predilection for local recurrence. there are very few reports in the literature that describe featur...

Image denoising has become an essential exercise in medical imaging especially the Magnetic Resonance Imaging (MRI). This paper proposes a medical image denoising algorithm using contourlet transform. Numerical results show that the proposed algorithm can obtained higher peak signal to noise ratio (PSNR) than wavelet based denoising algorithms using MR Images in the presence of AWGN.

case presentation we present a case with a typical picture of myocarditis but normal echocardiographic findings, the diagnosis of which was confirmed by cardiac mri. discussion in particular, cardiac mri data are useful in borderline cases or in the presence of discrepancy between clinical picture and echocardiographic results. introduction the diagnosis of myocarditis based on a spectrum of fi...

levamisole is an anthelmintic agent and also immunostimulant drug which is used to treat colorectal cancer. the present study aimed to show accidental consumption of levamisole alone induced multifocal inflammatory leukoencephalopathy. a 53-year-old male was admitted to the neurology department of farabi hospital (kermanshah, iran) with walking inability and recognition disorder. following clin...

background imaging plays a critical role not only in the detection, but also in the characterization of lung masses as benign or malignant. objectives to determine the diagnostic accuracy of dynamic magnetic resonance imaging (mri) in the differential diagnosis of benign and malignant lung masses. patients and methods ninety-four masses were included in this prospective study. five dynamic seri...
