This paper contains the results of cl inical studies with 0.1 and 0.15 Tesla KAIS NMR Tomograph which was developed by Korea Advanced 1 nstitute of 5cience. A variety of imaging modes such as saturation recovery(SR), spin echo(SE), and inversion recovery(SR) as well as echo and repetition times were applied. Clinical imagings were performed on 22 patients with dlseases of brain (15 cases), cervical spine(2 cases}, chest (2 cases), pancreas (2 cases), and kidney (1 case). In SR imaglng, we have obtained images strongly dependent on the hydrogen nuclei density. SE with long echo time and IR are effective for T2 and T1 dependent images, respectively. Results of clinical NMR imaging are presented and compared with X-CT and the other radiological examinations. Obtained results appear promising and with further examinations along with parameter adjustment, it is expected that the NMR imaging will not only substitute many conventional diagnostic methods such as X.ray CT but also be useful for the early detection of tumor and other lesions not obtainable with other modalities.
