fat necrosis is a benign inflammatory process which can involve adipose tissue anywhere in the body. a previous history of trauma or surgery may or may not be present. information about the clinical and radiological appearance of this lesion is very important because it can mimic breast cancer. in this article, we review the features of fat necrosis in different imaging modalities including mam...

background transfusion-induced iron overload leads to many complications in patients with β-thalassemia major. this study aimed to compare the level of iron stored in the liver and heart measured by mri t2 * with ferritin levels in these patients. materials and methods this study was done on 52 patients with β-thalassemia major aged 7 to 29 years. serum ferritin level was checked and heart and ...

the initial experience concerning the use of magnetic resonance imaging in 94 patients who had sustained chronic cord injury showed its specific advantages over traditional imaging modalities. a variety of 84 cord abnormalities were identified including myelomalacia in 47%, cord cysts in 37%, focal atrophy in 11 % and cord transection in 5%. canal stenosis was seen in twenty-five patients, elev...

Introduction:  Image  distortion  is  one  of  the  major  problems  of  magnetic  resonance  imaging  (MRI) for use in 3DMRI, velocity MRI, FMRI and radiotherapy treatment planning (RTTP). It is  widely known that the most obvious effect of the inhomogenity of the magnetic fields and the  nonlinearity  of  the  gradient  is  the  Geometric  Distortion  of  MR  tomograms.  In  this  study,  the...

conclusion a higher magnetic field strength and a decrease in the hr resulted in an increase in body temperature during the mri procedure. results our investigation of the physiological response to rf heating indicated a link between increasing age and body temperature. a higher increase in body temperature was observed in older patients after a 3.0-t mri (r = 0.07, p = 0.29 for 1.5-t mri; r = ...

Modern challenges of food science require a new understanding of the determinants of food quality and safety. Application of advanced imaging modalities such as magnetic resonance imaging (MRI) has seen impressive successes and fast growth over the past decade. Since MRI does not have any harmful ionizing radiation, it can be considered as a magnificent tool for the quality control of food prod...
