이 강의의 목적은 fat suppresion 과 water suppression에 관계되는 수소자기공명영상법의 기본 원리를 포괄적으로 이해하는데 있다. 임상적으로 이런 Technique의 수행이 필요한 가장 간단한 이유는 다른 병소의 신호와 구별을 하고 불필요한 artifact을 제거하기 위함이다.

When the low magnetic field is applied to the synunetry axis of the axial synunetric electric field gradient tensor of the quadrupolar nucleus in the crystal with nuclear spin, I=1, two split resonance frequencies are observed by the Zeeman effect on the nuclear quadrupole resonance. The applied magnetic field is proportional to the difference of the two resonance frequencies and this proportionality constant for the $^{14}N$ of ${(CH_{2})}_{6}N_{4}$ single crystal is 0.16 mT/kHz. The NQR spectrometer is interfaced with a personal computer from which the resonance signals are displayed and the value of magnetic field is obtained directly from the difference of the two resonance frequeocies. The lowestest measured magnetic field was 0.20 mT using this NQR technique.
