A study of Wideband MR imaging: SNR and CNR
Most of the MR image accelerating methods suffer from degradation of acquired images, which is often correlated with the degree of acceleration. However, Wideband MRI is a novel technique that transcends such flaws. In this study we demonstrate that Wideband MRI is capable of obtaining images with identical quality as conventional MR images in terms of SNR, CNR (contrast-to-noise ratio) and ima...

متن کاملEvaluation of radiolabeled streptokinase for thrombosis imaging
Introduction: Cardiovascular disease is the major cause of morbidity and mortality in developing and developed countries. Rapid diagnosis of the thrombosis can be an essential step in management of the stroke. Methods: In this work a recently developed radiolabeled streptokinase (STP) tracer was evaluated in an animal thrombotic model using SPECT imaging and biodis...
متن کاملEvaluation of platybasia with MR imaging.
BACKGROUND AND PURPOSE Platybasia, or abnormal obtuseness of the basal angle, was first measured on plain skull images. At present, evaluation of the brain and skull more commonly involves CT and MR imaging. We evaluated a new MR imaging method of evaluating platybasia. METHODS We retrospectively evaluated midline sagittal MR images in 200 adults and 50 children. The basal angle of the skull ...
متن کاملMR imaging evaluation of perianal fistulas: spectrum of imaging features.
Perianal fistulization is an inflammatory condition that affects the region around the anal canal, causing significant morbidity and often requiring repeated surgical treatments due to its high tendency to recur. To adopt the best surgical strategy and avoid recurrences, it is necessary to obtain precise radiologic information about the location of the fistulous track and the affected pelvic st...
