Bone scan measuring bone metastasis were analysed in fifty five patients diagnosed as malignant tumor, seven were primary bone tumor and forty eight were metastatic tumor, who treated in Kyung Hee Hospital from March 1981 to January 1982. The results were as follows: l. In 55 patients, positive bone scan were found in 76.4% of the patients and positive X-ray were found in 56.4%. 2. 7 patients with primary bone tumor showed all positive bone scan, 45 patients with metastatic tumor showed positive bone in 72.9%. 3. Among the patients with metastatic tumor who no clinical symptoms, positive bone scan were found in 59.3% and positive X-ray in 26%. 4. Most common metastatic site was femur in primary bone tumor and vertebra in metastatic tumor. 5. In 48 patients of metastatic tumor, positive bone scan within negative X-ray were found in 56%, negative bone scan within positve X-ray were found in 5%. 6 The lesions showed clod area on bone scan were considered of positive finding as compared with clinical symptom and X-ray finding.

PURPOSE: Functional MR imaging is the method of demonstrating changes in regional cerebral blood flow produced by sensory, motor, and any other tasks. Functional MR of visual cortex os performed as a patient stares a photic stimulation, so adaptable photic stimulation is necessary. The purpose of this study to evaluate whether the size of photic stimulation can affect the degree of visual cortex activation. MATERIALS AND METHODS: Functional MR imaging was performed in 5 volunteers with normal visual acuity. Photic stimulator was made by 39 light-emitting diodes on a plate ,operating at 8 Hz. The sizes of photic stimulator were full field, half field and focal central field. The MR imager was Siemens 1.5-T Magenton Vision system, using standard head coil. Functional MRI utilized EPI sequence (TR/TE=1.0/51. 0msec, matrix No.=98x128, slice thickness=8mm) with 3sets of 6 imaging during stimulation and 6 imaging during stimulation and 6 imaging during rest, all 36 scanning were obtained. Activated images were obtained using postprocessing software(statistical analysis by Z-zone, and these images were combined with T-1 weighted anatomical images. The activated signals were quantified by numbering the activated pixels, and activation index was obtained by dividing the pixel number of each stimulator size with the sum of the pixel number of 3 study using 3 kinds of stimulators. The correlation between the activation index and the stimulation size was analysed. RESULTS: Mean increase of signal intensities on the activation area using full field photic stimulator was about 9.6%. The activation index was greatest on full field. second on half field and smallest in focal central field in 4, The index of half field was greater than that of full field in 1. The ranges of activation index were full field 43-73%(mean 55%), half field 22-40%(mean 32%), and focal central field 5-24%(13%). CONCLUSION: The degree of visual cortex activation increases with the size of photic stimulator.

PURPOSE: To evaluate MRI findings of spinal cord according to mechanism in acute cervical spinal injury. MATERIALS AND METHODS: 25 patients under went MRI within 1 month after acute cervical trauma. Axial T1WI (TR/TE :500/20), gradient-echo (TR/TE :300/14), sagittal T1WI (TR/TE:500/20), proton (TR/TE :2000. 20 msec), T2WI (TR/TE :2000/80) were performed. In 11 pateints, post-enhancement T1WI was done. Change of spinal cord signal intensity on MRI in addition to the presence of abnormal changes of vertebral body, intervertebral disc and paraspinal soft tissue were evaluated. RESULTS: 15 patients had flexion injury, seven had extension injury and three had injury of unknon mechanism. Twelve patients showed /so-signal intensity on T1WI and high signal intensity on T2WI. Three patients showed low signal intensity on T1WI and high signal intensity on T2WI. Spinal cord hemorrhage occured in 10 patients. We found cord swelling in nine patients and cord compression in 12 patients. In nine patients with cord swelling, extent of cord injury was more than one segment of vertebral body. Ligamentous injury, disc injury, soft tissue injury occurred in 16(64%), 17(68%), 15(60%) patients respectively. Vertebral body fracture was found in 17 patients (68%). The levels of fracture were C6(eight patients) and C5(five patients). CONCLUSION: MRI is valuable in exaluetion of the spinal cord, intervertebral disc, and soft tissue lesions in acute cervical spinal injury. Prognosis is worse in flexion injury than in extension injury, and is well correlated with cord hemorrhage and lesion extent.

BACKGROUND/AIMS: The most effective method of improving survival in patients with HCC is early diagnosis and curative hepatic resection. However, longterm survival after curative resection remains low because of high recurrence rate after resection. The purpose of the study is to assess the prognosis and the efficacy of the various treatment modalities on recurrent HCC after curative resection. METHODS: The clinical records of 50 patients with recurrent HCC were reviewed retrospectively who underwent curative surgery in Yonsei University, Severance Hospital from Jan. 1987 through Oct. 1994. The cummulative recurrent rate after resection, the response rate of treatment after resection, the median progression free survival and the survival after recurrence according to the treatment modalities were evaluated. RESULTS: The cummulative recurrent rate after resection was 3.9% at 3 month, 8.3% at 6 month, 14.1% at 12 month, 21.5% at 24 month, 23.4% at 36 month and 24.4% at 60 month. The response rate of treatment after recurrence was 23.7% (9 patients). The median progression free survival of the patient with reoperation and hepatic embolization was 13.9 months, that of conservative treatment group was 6.8 months and that of no treatment group was 4 months(p = 0.004). The survival after recurrence of HCC was 19.7 months in reoperation and hepatic embolization group, 11.4 months in multimodality group, 16.9 months in conservative treatment group and 8.4 months in no treatment group(p=0.0998). CONCLUSION: Reoperation and hepatic embolization for HCC after curative resection was effective in improving progression free survival, but overall survival were not significantly different according to the treatment modalities. This results proposed that reoperation and hepatic embolization for recurrent HCC after curative resection improve progression free survival.

PURPOSE: Ganglioglioma is a rare primary brain tumor usually found in the temporal lobe. The purpose of thisstudy is to describe the characteristic MR findings of temporal lobe ganglioglioma. MATERILA AND METHODS: Over aseven-year period, ten patients with cerebral ganglioglioma were evaluated at our institution. Seven cases oftemporal lobe ganglioma were found ; six of these involved men, and one, a woman ; their mean age was 29.6 years.In three patients, Gd-DTPA-enhanced T1 weighted images were also obtained. We retrospectively analysed the MRIfindings with respect to location, size, cortical involvement, margin, cystic change, degree of enhancement, MRsignal intensity, calcification and peritumoral change. RESULTS: In five cases, tumors were located within thetemporal lobe. In one, a tumor extended from the temporal lobe to the thalamus, and in one from the temporal lobeto the thalamus and cerebral peduncle. All temporal gangliogliomas measured 1.6-3.8cm in their greatestdiameter(mean diameter, 2.7cm). In all cases, the cortices were involved with the maintenance of gyriform. Thetumor margin was ill defined in five cases and well defined in two. Tumors showed multiple small cystic changes infour cases, a large cyst in two, and a solid nodule in one. In three cases in which contrast media wasadministered, no lesions were enhanced. On T1-weighted images, iso-signal intensities were seen in five cases andhigh signal intensities in two. On T2-weighted images, the corresponding figures were five and two. On MRI, tumorcalcification and calvarial erosion were each detected in two cases. CONCLUSION: In patients with temporal lobeepilepsy in whom cortical solid or cystic and poorly enhanced lesions were seen on brain MRI, and in whomaccociated findings such as calcification and or adjacent bony erosion were noted, ganglioglioma must beconsidered.
