        뇌동맥류파열의 전자화단층촬영 및 혈관조영 소견

        김정식 대한영상의학회 1984 대한영상의학회지 Vol.20 No.3

        CT has become one of the most important diagnostic method in the evaluation of ruptured intracranial aneurysm with direct detection of subarachnoid, intracerebral and intraventricular hemorrhage. and identification of complications such as recurrent bleeding, hydrocephalus and infarction secondary to arterial spasm. Angiography gives precise information on the location, size of aneurysm and presence of arterial spasm. Authors attempted to predict the location of reptured aneurysm in the CT by distribution of blood in subarachnoid spaces and brain parenchyme in comparison with angiographic findings, and also predict the prognosis of the patients by relationship between the extent of blood and clinical grade. Authors analysed 40 cases of ruptured intracranial aneurysm confirmed by CT and angiography at Keimyung Untversity Hospital for last 2 years. The results were as follows: 1. The age and sex distribution ; the most prevalent age group was 5 th to 6th decades (70%), and female patient was slightly more than male patient (57.5%:42.5%). 2. The location of aneurysms were; posterior communicating artery group 17 cases (42.2%), middle cerebral artery group 10 cases (25.0%), anterior communicating artery group 7 cases (17.5%), basilar artery bifucation 1 cases (2.5%), posterior inferior cerebellar artery 1 case (2.5%), and multiple aneurysms 4 cases (10%) in order to frequency. 3. Characteristic distributions of intracranial hemorrhage in CT were as follows; 1) In 6 cases (85.7%) of anterior communicating artery aneurysm, interhemispheric fissure hemorrhage was noted. 2) The ipsilateral sylvian fissure hemorrhage was noted in all cases of middle cerebral artery aneurysm (10 cases) and 12 cases (70.6%) of posterior communicating artery aneurysm. 3) Localized hematoma in frontal lobe near interhemispheric fissure (2 cases : 28.6%), septum pellucidum (1 case:14.3%) and corpus callosum (1 case:14.5%) were characteristic in anterior communicating artery aneurysm. 4) Commashaped sylvian fissure hematoma (5 cases:50%) and temporal lobe hematoma near sylvian fissure (5 cases :50%) may indicate middle cerebral artery aneurysm. 5) Intraventricular hemorrhage (6 cases :15%) has no particular predilection of aneurysmal location. 4. In 9 paients (22.5%) of clinically suggesting subarachnoid hemorrhage, no extravasated blood was noted in preenhancement CT alone. 5. Six cases (15%) showed aneurysm itself on preenhancement CT as a round or ovoid hyperdense area or isodense area with mass effect such as cisternal obliteration. 6. Hydrocephalus was noted in 9 cases (22.5%) 7. there was no direct correlation between the size of the intracranial aneurysm and extent of the hemorrhage in CT, and between the size of the intracranial aneurysm and clinical grade. 8. There was direct correlation between the extent of blood in CT and clinical grade.

        화학요법 전과 후의 자궁경부암의 자기공명영상

        To evaluated usefulness of MR in assessment of tumor response to the chemotheraphy, we prospectively studied cases of cervical carcinoma with more than 2.5cm in diameter or stage IIb or more. Three courses of chemotherapy were lperformed with cisplatin and 5 F-U. MR images were obtained both before and after chemotherapy. Nine of 13 patients were undertaken radical hysterectomy after chemotherpy and MR examination. MR volumetry, stage and depth of stromal invasion were compared before and after chemotherapy. And in 9 patients who underwent radical hysterectomy, comparison of pathologic and MR imaging findings were also done. The results were following : 1) All tumors dectrases in volume (m=80.5%). 2) Five tumors (38.5%) reduced in stage, IB longrightarrow CIS (1); IIA longrightarrow CIS (1), IIA longrightarrow IB(2), IIB longrightarrow IB(1). 3) Depth of stromal invasion in MRI correlated well with that of histo-pathologic specimen in 7 of the 9 patients. Conclusively MR imaging is useful in assessement of tumor response to chemotherapy.

        CT is useful for the evaluation of detailed morphologic change renal function and extrarenal involvement in renal tuberculosis. authors analysed the CT findings of 15 patients of renal tuberculosis which were confirmed at Keimyung University Hospital from Jan '82 to June '88 The results were as follows: 1. The Kidneys were enlarged in 6 cases (40%) and lobulated in 10 cases (67%) 2. The thickness of renal parenchyme was decreased in 13 cases(87%) 3. The renal function was absent in 8 cases (57%) 4. The calyectasis were in 11 cases (73%) and pelvocalyectasis were only in 1 cases(7%) 5. The renal calcifications were in 9 cases (60%) 6. The wall of ureterw were thickened in 11 cases (73%) 7. The extrarenal involvement were in 7 cases (47%) Conclusively we considered the possibility of renal tuberculosis when thickened wall of the renal pelvis and /or ureter calyectasis with renal pelvis contraction and loss of the renal sinus fat were present.

        만성미만성 폐질환의 전산화단층촬영 소견

        김정식 대한영상의학회 1990 대한영상의학회지 Vol.26 No.2

        We evaluated the CT findings of 21 cases of chroinc diffuse lung disease which were diagnosed with open lung biopsy(7), transbronchial lung biopsy(3), bronchoalveolar lavage(4), occupational history(2), skin biopsy(2), liver biopsy(1), bone marrow aspiration(1), clinical functional and radiographic findings(6). CT scans were obtained by using 8mm collimation at 8mm intervals in all patient, and additional high resolution CT scans(1mm collimation) were also obtained in 17 patients of them. Although the traditional classification method of disease distribution into upper, middle and lower zones was somewhat useful, the model of disease distribution proposed by Bergin and Muller was more useful in evaluation of chroinc diffuse lung diseases. The diseases that were mainly distributed in axial compartment were lymphangitic carcinomatosis(5), sarcoitosis(2) and those in middle compartment were silicosis(2), extrinsic allergic alveolitis(1), hypereosinophilic syndrome(1), unclassifie one(1) and in peripheral compartment were fibrosing alveolitis (idiopathic pulmonary fibrosis(3), Rheumatoid lung(1), scleroderma(1), dermatomyositis(1) And in diffuse panbronchiolitis(3), even distribution of lesions to both axial and peripheral compartments was noted. But in fibrosing alveolitis, some degree of distribution was noted in peripheral compartment and in lymphangitic carcinomatosis and silicosis, some degree of distribution was noted in peripheral compartment. Nodular thickening of bronchovascular bundles was characteristically seen in all cases of lymphangitic carcinomatosis and sarcoidosis. The nodules were 1-5mm in diameter and were composes of tumor cells9in lymphangitic carcinomatosis) and of sarcoid granuloma within lymphatics in the bronchovascular sheath. however patients with sarcoidosis did not have irregular thickened interlobular septa and polygojal line. Dilatation of peripheral airways without dilatation of proximal bronchi was only seen in diffuse panbro chiolitis. Although we experienced only two cases of silicosis, the nodules of silicosis were separated from the pleura at a constant distance and seldom touched to the pleura.

        원발성 종격동 정상피종의 전산화단층촬영 소견

        김정식 대한영상의학회 1988 대한영상의학회지 Vol.24 No.5

        Primary mediastinal seminoma is a rare germ cell tumor that usually occurs in young men. Recently we experienced two cases of primary mediastinal seminoma with CT scan. CT findings were a large anterior mediastinal mass which grows mainly to the left and displaces left brachiocephalic vein posteriorly lobulated tumor margins with small spiculations or projections loss of fat planes between the tumor and surrounding organs and homogeneous density of 40-50 HU in postcontrast study. These CT findings may suggest the possibility of primary mediastinal seminoma before histologic confirmation.

        Rheology of three natural lacquers, Korea, China and Japan has been studied for the storage(G' ) and loss(G") Young's modulus shear velocity of viscosity. The storage(G' ) and loss(G") Young's modulus of all lacquers are increased with increasing a frequency. The slope of storage(G') and loss(G") Young's modulus for the Japan were greater than the Korea and the Chinaby by a factor of 3. The viscosity is non-linearly decreased with increasing the shear velocity in the range of 0.01∼30, which indicates non-Nowton fluid with the shear thinning. The behaviors of shear thinning for the Korea and the China appear clearly in comparison with the Japan. This might be intimately related to the degree of purity of the laquer. The Japan has a higher purity than the Korea and the China.
