DESCRIPTION:There is a continuing need for improved signal-to-noise ratio 
 in detection of magnetic resonance signals\, since this can increase resol
 ution both in MR imaging and in MR spectroscopy\, and potentially allow ea
 rlier detection or diagnosis of potentially lethal tumours. Small\, intern
 al probes can increase SNR through a combination of closer coupling to the
  signal source and reduced sensitivity to body noise. However\, microfabri
 cation techniques are required to realise high-performance detectors at lo
 w cost and in clinically useful formats. This talk will provide an overvie
 w of the design issues and present examples of two recently demonstrated d
 evices: a rigid needle-shaped detector designed for complete immersion in 
 excised tissue and a flexible catheter-mounted detector capable of passing
  the biopsy channel of an endoscope and into the biliary duct system.
