However, limitations of tumor oxygen imaging using the MR-T2* technique due to patient compliance, target movement, geometrical distortion and limited field of view were present.

Our results are consistent with those of other studies using different MR techniques.
Focal lesions are easily detected when using appropriate MR techniques such as fat suppressed T2 WI before treatment.
Localisation and acquisition of H-MR spectra were performed using the PRESS technique (TR, 1600 ms, TEs, 68, 135 and 270 ms).
It is often difficult to say who is winning right until the end.In this section Weighing the universe Winning ways Well-meaning mums Casting eggs into the waters The Richard Casement internship ReprintsDeep Blue and its successors beat Mr Kasparov using the "brute force" technique.
On T2 ∗ -weighted imaging, the signal intensity of RMS was measured by an author (J.S., with more than 12-year experience with MR imaging), using the technique of region of interest with a minimum size of 50 pixels and the decrease of signal intensity was normalized to the contralateral normal brain parenchyma.
Yet within a few years, all computer-makers were using the same technique.Mr Beyers told Bill Hewlett and Dave Packard, the company's founders, that the idea was being copied, and tried to persuade them to enforce the patent.
Experimentally, 608 × 608 × 1,408 voxels were acquired in the x-, y-, and z-directions, respectively, which were zero filled to create the full MR data stack containing 1,024 × 1,024 × 2,048 voxels with corresponding edge lengths of 26.4 × 26.4 × 24.4 μm (zero filling is a commonly used MR technique to visually improve an image without in fact adding additional structural information).
