116 LÆKNABLADID Fig. 18. Sagittal scan in a patient with an endometri- oma within the Pouch of Douglas. Fig. 19. Transverse scan through the thorax in a patient with a left ventricular aneurysm. The en- larged thin walled left ventricle is well shown together with organised thrombus at the apex which is projecting into the lumen. Fig. 20. Coronal scan through the knees in a patient with an osteosarcoma of the lower left femur. The soft tissue spread and the intra-medullary extension of the tumour is clearly defined. indispensable in CT, would allow clear identi- fication of loops of bowel and the mapping of a breakdown in the biood brain barrier. Because of their lesser abundance in biological tissues and smaller inherent NMR signal imaging using other magnetic nuclei will only be possible at either ntuch lower resolution or with very long exposure times. ACKNOWLEDGEM ENTS The author would like to pay tribute to his Physicist colleagues, Dr. W. S. Moore, Mr. G. N. HoIIand and Dr. R. C. Hawkes for the many contributions which they have made to laying the physical foundations of NMR imaging. Thanks are also due to Mr. John Williams and Dr. Gordon Higson of the Depart- ment of Health and Social Security for their continued support and encouragement.
