1. A method of internal magnetic resonance analysis of a specimen comprisingpositioning said specimen within a main magnetic field,introducing an invasive probe having an elongated receiver coil into said specimen,employing as said receiver coil a resiliently flexible coil having at least one pair of elongated electrical conductors disposed within a resiliently flexible dielectric material and having a pair of ends electrically connected to each other,maintaining the spacing between said pair of elongated electrical conductors substantially uniform throughout said analysis,imposing said main magnetic field on region of interest of said specimen,applying RF pulses to said region of interest to excite magnetic resonance signals within said specimen,applying gradient magnetic pulses to said region of interest to spatially encode the magnetic resonance signals,said receiver coil receiving said magnetic resonance signals and emitting responsive output signals,processing means for receiving and processing said output signals and converting them into MR information, andemploying display means for receiving MR information from said processing means and displaying the same as an image or as chemical shift spectra.
