Metaphyseal cysts are common findings in Legg-Calv Perthes(LCP) disease, though usually disappear within 6-12 months. Several studies have described the MR imaging findings of these cysts, though serial MRI findings have not been documented. In this report, therefore, we report the serial MRI results of metaphyseal cyst in LCP patients.

In order to observe the pattern of a flow image on multisection MR imaging technique, a flow phantom experiment was preformed using a superconducting high filed 2.0 Tesla MRI scanner. The pattren of the first section images was homogeneous round at all flow velocities until the turbulence forming level. The patterns of the second section images,however,changed into a homogeneous round shape, a ring shape, a target shape, and a small round shape as the velocity increased. When scanned at velocities higher than the trubulence forming level, the images become distored and irregular, and eventually disappeared after the cut-off velocity. The homogeneous round image senn at the lower velocity levels in throught to be due to the overwhelming effects of fully managetized spins influxed into the imaging section during the prior repetition time(TR). Later in the higer velocity levels the effects of the partially saturated spins and fully magnetized spins influxed during the section transit time(TR/slice number) are added, and result in ring, target, and small round patterns in the second section image.

10.Analysis of Anterior-posterior Distance of Sacral Canal on MRI to See the Possibility of Sacral Laminar Hook Insertion.
Journal of Korean Neurosurgical Society 2003;34(5):445-449
OBJECTIVE: Achieving successful posterolateral fusion across the lumbosacral junction is particularly problematic. In our hospital, bilateral S2 laminar hooks coupled with bilateral S1 screws have been appeared to provide successful posterolateral fusion of lumbosacral junction in high non-fusion risk patients. Therefore we study about the safety of sacral lamina hooks insertion. METHODS: We measured the anterior-posterior(A-P) diameter of sacral canal at a point where median sacral crest of S1 and S2 meet on lumbar magnetic resonance(MR) sagittal images. The number of analyzed subjects was one hundred and minimum A-P diameter of sacral canal to insert laminar hooks safely was thought to be 9mm. RESULTS: In 78% of study cases, the sacral canal diameter was 9mm or more. There were no statistically significant difference of sacral canal diameter with age, sex, weight and height. CONCLUSION: Preoperative analysis of the sagittal MR image may be helpful for the safe insertion of the sacral laminar hooks to enhance posterolateral fusion of lumbosacral junction in high non-fusion risk patients. And, safe sacral laminar hooks insertion may be possible in about 78% of study cases.
