The presence of the head in an MRI scanner leads to inhomogeneities in the magnetic field. These cause the 'susceptibility artifacts' of image distortion and signal dropout. In this paper, we evaluate a technique called passive shimming, which has the potential to reduce field inhomogeneities and the resultant artifacts. A piece of a magnetically active(More)
Amplification of the c-myc oncogene has been described in both moderately well differentiated and poorly differentiated gastric adenocarcinoma (Shibuya et al., 1985; Koda et al., 1985). The greatest levels of c-myc mRNA were observed in the poorly differentiated tumours (Shibuya et al., 1985). It would seem likely therefore that detectable levels of the(More)
