Signal-intensity-ratio MRI accurately estimates hepatic iron load in hemodialysis patients
BACKGROUND Iron overload, diagnosed by means of magnetic resonance imaging (MRI), is an increasingly recognized disorder in hemodialysis patients. Specific MRI protocols have been shown to provide a reliable estimation of tissue iron content in non-renal patient populations but have not been validated in dialysis patients. Such validation studies require liver biopsy for histological comparison...
متن کاملMRI R2 and R2* mapping accurately estimates hepatic iron concentration in transfusion-dependent thalassemia and sickle cell disease patients.
Measurements of hepatic iron concentration (HIC) are important predictors of transfusional iron burden and long-term outcome in patients with transfusion-dependent anemias. The goal of this work was to develop a readily available, noninvasive method for clinical HIC measurement. The relaxation rates R2 (1/T2) and R2* (1/T2*) measured by magnetic resonance imaging (MRI) have different advantages...

متن کاملUsing Inaccurate Estimates Accurately
Job schedulers improve the system utilization by requiring users to estimate how long their jobs will run and by using this information to better pack (or “backfill”) the jobs. But, surprisingly, many studies find that deliberately making estimates less accurate boosts (or does not affect) the performance, which helps explain why production systems still exclusively rely on notoriously inaccura...
