Rapid Blood T1 Calibration for Arterial Spin Labelling

摘要: 2 ). Most of the selected voxels belong to sagittal sinus, with some contribution from peripheral vessels, meaning that T1b values obtained refer venous blood. Values for T1 doped water measured in phantom using our sequence and method (T1=533 ± 21 ms) were good agreement independent inversion recovery measurements absence flow (T1=559 10 ms), thus confirming validity MR analysis method. It was found use tissue saturation pulse helped suppress signal first few data points, but as these subsequently rejected, had little impact on final results. The are listed table 1. quoted uncertainty (95% confidence interval) is relative least-squares fitting process does not include associated outlier rejection criteria. This results error 1 being an underestimate whole
