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.
