Sintering, microstructure, thermal conductivity and microwave dielectric properties of xLiF-(1-x)MgO ceramics (x=0.03~0.10 mol) were investigated. The high density was obtained in the specimens of $x{\geq}0.06$, i.e., 0.04 LiF-0.96 MgO in mol, whereas the amount of 0.03 mol LiF was insufficient to densify. From the result that the contact flattening in the sintered specimen was observed, the densification occurred through the liquid-phase sintering. The specimen of x=0.06 showed the highest room-temperature thermal conductivity. Relative density, thermal conductivity, dielectric constant, and quality factor ($Q{\times}f$) of the specimen for x=0.06 sintered at $900^{\circ}C$ for 4 h were 97.8%, $39.2Wm^{-1}K^{-1}$, 9.45, and 14,671 GHz, respectively.

N/A Pheochromocytoma occurs at all ages but is most common in young to midadult life. In adults 10 percent of pheochromocytoma are bilateral. And bilateral lesions are common in the familial syndromes; within Multiple Endocrine Neoplasia (MEN) kindreds over half with pheochromocytomas have bilateral lesions. We report a case of bilateral pheochromocytoma firstly detected by ultrasonogram. This 24-year-old male was normotensive and had symptoms of dilated cardiorrmyopathy and elevated VMA level. CT and MRI were performed to evaluate the tissue nature and associated abnormalities. 131I-MIBG scan seems to be the imaging of choice in patients with suspected multicentric,/bilateral or recurrent or metastatic pheochromocytomas.

최근 2년 6개월간 인제의대 부산 백병원에 내원하여 Iopamidol제제를 척수 강내로 주입하여 척수조영술과 CT 척수조영술을 시행한 278명의 환자를 대상으로 후향적 분석을 하여 다음과 같은 결론을 얻었다. 척수조영술상 경막낭이 완전히 차단된 경우, CT 척수조영술은 차단 부위 이하 또는 그 이상의 병변을 잘 관찰할 수 있어 차단 원인과 침범 범위를 정확히 볼 수 있었다. 요추간판 탈출증에 있어 CT 척수조영술은 척수조영술과 비슷한 진단율을 보였지만 요추간판 석회화와 진공 현상 뿐만 아니라, 추관절 병변, 인대비후, tropism, Schmorl's node 등을 더 잘 나타내었다. CT 척수조영술은 척수종양과 감염의 종류와 주위 조직으로의 파급 정도를 평가하는데 도움이 되었다. CT 척수조영술은 또한 선천성 질환의 병변의 종류 및 침범 범위, 그리고 연관된 다른 기형을 잘 볼 수 있었다. 척수 손상에 있어서 CT 척수조영술은 척수 조영술에 비해 척추강내 출혈, 골편 및 손상의 정도를 평가하는데 매우 유용하였다. Computed Topography with administration of intrathecal contrast material (Iopamidol) was evaluated retrospectively in 278 patients. In all patients, both myelography and CT myelosraphy was performed. 1) On high grade subarachnoid obstruction in myelography, CT myelography demonstrates the cephalad or caudal extent of block with nature and extent of the lesion. 2) On disc disease, CT myelography well demonstrates protruded disc itself with disc calcification and vaccum phenomenon, as well as associated findings such as facet joint change, thickening of ligament flavum, posterior bony spur, tropism, Schmorl's node, etc. 3) CT myelography is helpful in evaluating the nature and paraspinal extent of infection and tumor. 4) In spine trauma, CT myelography is also useful in the evaluation of hemorrhage or bony fragment in spinal canal and spinal cord injury. 5) CT myelography also clearly demonstrates the extent and nature of the congenital anomalies such as spinal dysraphism or epidural cyst, with associated anomalies. 6) So, CT myelography should be considered as valuable diagnostic modality in the evaluation of various spinal diseases.
