FAT-SUPPRESSED MAGNETIC-RESONANCE-IMAGING AT 1.5 TESLA OF NEOPLASMS OF THE LIVER AND PANCREAS

We investigated 55 patients with suspected neoplasms of the liver and/ or pancreas using fat-suppressed spin echo and gradient echo MR sequen ces. T1 and T2 weighted fat-suppressed spin echo sequences provided hi gher sensitivity for the detection of liver metastases. In the diagnos is of pancreatic tumours, T1 weighted fat-suppressed gradient echo seq uences after application of intravenous and oral paramagnetic contrast agents offered more information than other sequences. Drawbacks of fa t-suppressed sequences are an increase in scan time and inhomogeneous fat-suppression at the periphery of the image.
