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.

Omentum has the characteristic that it readily develops vascular anastomosis with adjacent tissues. It is suitable for eliminating a dead space regardless of the size, shape or site in the treatment of chronic osteomyelitis by use of technique of microvascular anastomoses. We report a case of chronic osteomyelitis treated by transplantation of autogenous omentum with microvascular anastomsis.

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.

One hundred fifty-four patients with the carcinoma of the uterine cervix were studied retrospectively to assess the result and impact of treatment at Department of Radiation Oncology, Korea University, Hae-Wha Hospital from Feb 1981 through Dec. 1986. Prior to radiotherapy, the patients were evaluated and staged by recommendation of FIgO including physical examination, pelvic examination, cystoscopy, ectosigmoidoscopy, chest X-ray, IVP, Ba enema. Also, an additional pelvic CT scan was obtained for some of the patients. The patients were treated by radiotherapy alone or adjuvant postoperative irradiation; In case of radiation therapy only, whole pelvic irradiation was given with C0-69 teletherapy unit via AP and PA parallel opposing fields or 4-oblique fields, 180 cgy per day, 5 days per week and intracavitary insertion was performed. In stages la, lb, and lla with small primary lesion, external irradiation was initially given to pelvis up to 2000~3000 cgy/2x(1/2)-3x(1/2) weeks and then intracavitary insert in was performed using Fletcher-Mini-Declos Applicator with cesium-137 courses and followed by external irradiation of 1000~2000 cgy 1x(1/2)-2x(1/2) weeks via AP and PA parallel opposing fields with midline shield to spare of bladder and rectum. However, if the primary lesion is large, external irradiation was given without midline shield. More than stage llb, the patients were treated by external beam irradiation up to 5400 cgy/30f for 6 weeks via 4-oblique portals and at the dose of 5040 cgy/28f the field was cut 5 cm from the top margin for spare of small bowel, and followed by intracavitary irradiation. If there was residual tumor, an additional dose of 900~1200 cgy/5~7f was given to parametrium and/or residual tumor area. Total dose of radiation of A and B-point were as follows; A-point : B-point In early stages, la, lb, llb ; 8000~9000 5000~6000 cgy In advanced stages llb, llla, lllb; 9000~10000 6000~7000 cgy The results were obtained and as follows; The patients distribution according to FIgO staging system were stage la 6, lb 27, lla 28, llb 54, llla 12, lllb 18, and stage lVa 9. Value of CT scan were demonstration of cervix tumor mass, parametrial and pelvic side wall tumor spread, pelvic and inguinal lymph nodes metastases, and hydronephrosis. Three dimensional quantitative demonstration of tumor volume is also important in planning radiation therapy. Another advantage of CT scan was detection of recurrent tumor after radiation or surgery. Local control rate of tumor according to the size was 91.3% for less than 5 cm in size and 44.6% in tumor over 5 cm (p<0.0068). Thirty out of 50 recurrent sites has locoregional failures and 17 cases has distant metastases. And the papa-aortic lymph nodes were the most common site for distant metastases. The most common complication was temporal rectal bleeding which was controlled most by conservative management. However, 4 patients required for endoscopic cauterization. The 5-year survival rates showed; stage la and lb 95%, stage lla 81% stage llb 67%, stage llla 37.7%, stage lllb 23%, and 3-year survival rate of stage lVa showed 11.6%, retrospectively.

Malposition of catheter in the subdural space is a possible complication during attempted epidural anesthesia. We report here an inadvertent subdural block confirmed by the radiographic contrast materiaL Epidural anesthesia was planned for a full-term gravida and epidural catheter was inserted about 3 cm cranially at the level of L1-2. After injection of 19.5 ml local anesthetic, blood pressure was 70/50 mmHg. Fluid was rapidly infused and intravenous ephedrine 10 mg was given. After then, vital signs were well maintained and twin babies were delivered without events. Twentyfive minutes later, she complained chest tightness and became tachypneic. Ketamine 50 mg was given and endotracheal intubation was performed with ease. She obeyed command, but could not open her eyes for some duration. Self respiration returned after 110 minutes and minute ventilation was 6 liter/minute at that time. 160 minutes later, extubation was done and radiological examination was performed using contrast materiaL The cathter tip was positioned in anterior subdural space at T12 level.
