We observed a significant sign in postenhancement CT of liver cirrhosis, that is visualization of portalvenous branches. During postenhancement CT scanning of liver, the portal vein can not be identifed in liverparenchyme in 84% of patients without known cirrhosis (including chronic active hepatitis). Two have the samehemodynamic changes in that there is diffuse fibrosis and resultant decrease in vascular bed. Visualization ofintrahepatic portal branches in postenhancement CT is because of decreased diffusion ability and portalhypertension.

The present study was performed to provide an anatomical basis of the coracoacromial (CA) arch and the articular surfaces of the scapula which can be applied to the diagnosis and treatment of some common shoulder problems. The standard dimensions and the range of variation of the CA arch, the acromial articular surface and the glenoid cavity were investigated in 114 dry scapulae obtained from 57 (male, 35 ; female, 22) Korean cadavers ranging in age from 18 to 97 years (average age of 67). The results were as follows : 1. The length (46.3mm), width(25.2mm), thickness (8.2mm) and height (4.5mm) of the acromion were measured. The length, width and thickness were significantly larger in the males. The slope of the acromion was 51.5°, and the slope of the scapular spine was 118.5°. 2. The height (13.5mm), slope of the root (138.4°) and the horizontal part (25.3°) of the coracoid process, and the angle between the root and the horizontal part (106.6°) were measured. There were no significant differences between sexes and sides in all morphometric values related to the coracoid process. 3. The length (67.6mm) and height (24.7mm) of the CA arch, the height of the CA ligament from the supraglenoid tubercle (13.1mm), and length of the CA ligament (27.6mm) were measured. Both the length and height of the CA arch and the length of the CA ligament were significantly larger in the males. The slope and anterior and posterior angles of the CA arch were 16.8°, 42.2°, and 34.7°, respectively. 4. The long (13.8mm) and short (8.0mm) diameters of the acromial articular surface were measured, and both diameters were significantly longer in the males. The acromial articular surface was 8.4mm away from the tip of the acromion and extended 1.4mm inferiorly below the inferior surface of the acromion. 5. The long (34.8mm) diameter, and superior (15.0mm), middle (19.5mm), and inferior (25.6mm) short diameters of the glenoid cavity were measured. The long and both superior and inferior short diameters were significantly longer in the males.

Evaluations of residual renal function and the therapeutic effectiveness in renal tuberculosis have largely been dependent on intravenous pyelogram or Contrast-CT scan, even though, exact renal function are not evaluated with there methads. 99mTc-DMSA is a radiopharmaceutical that is trapped in the functioning tubular cells of the kidney and therefore, quantitative renal function could be evaluoted by ineasuring the counts of renal radioactivity and concomittant evaluation of renal morphology could be passible with the analog imapes of the radioactivity. The authors retrospectively analyzed 99mTc-DMSA scans of 75 kidndys of 67 patients with confirmed renal tuberculosis. We classified the morphologies of tuberculous kidneys as 6 types. We classified the morphologies of tuberculous kidneys as 6 types such as the type with small cortical defect, with parenchymal ulcerocavernous lesions, ulcerocavernous fistula to pelvis, mass-like defects, contracted kidney with ureter visualization, and the type with nonvisualization of kidney, corresponding to the characters of renal tuberculous pathogenesis with abscess formation, ulcerocavernous fistula, and fibrosis, and correspondings to the renal anatomy with parenchyma, and pelvocalyceal collecting system. Their mean residual renal functions measured with 99mTc-DMSA uptake rates were 19.0%, 18.4%, 7.9%, 12%, 4.1%, 3.4% respectively.

PURPOSE: To compare the suppressive effects in hepatocellular carcinoma patients of transhepatic arterial chemoembolization by the infusion of adriamycin-lipiodol emulsion and of this plus 10ml of cisplatin solution. MATERIALS AND METHODS: In a total of 151 cases, the frequency of intrahepatic recurrence was compared with follow-up angiographic findings after the first and second transhepatic arterial chemoembolization with adriamycin-lipiodol emulsion and adriamycin-lipiodol emulsion plus 10ml of cisplatin solution, respectively. RESULTS: Among 46 patients whose first single infusion was after mean 119 days, the recurrence rate was 22% ; for 42 who were given their first multiple infusion after mean 76 days this rate was 5% ; for 35 whose second single infusion was administered after mean 147 days, the rate was 34%, and among 28 whose second multiple infusion was after mean 110 days, the rate was 43%. CONCLUSION: During the first trial of transcatheter arterial chemoembolization with adriamycin-lipiodol plus cisplatin solution, hepatocellular carcinoma recurred much less frequently, but during the second trial with cisplatin, recurrence was not suppresed.

DRUC( Double Contrast Retrograde Urethrocystography), which was a combination of air cystography andretrograde urethrography with the patient in an exaggerated Trendelenburg's position allowing the contrast mediuminjected into bladder to be accumulated at the bladder base and dome far from trigone, showed good visualization of the prostatic urethra, bladder neck, bladder base and wall in contrast to the conventional, retrogradeurethrography. The authors analyzed DRUC findings of 32 cases of benign prostatic hypertrophy, 3 case of prostaticcancer and 50 cases of normal healthy men performed at Pusan National University Hospital for 9 months from Jan.1984 to Sept. 1984. The results obtained were as follows: 1. DRUC findings of normal control group were normalpattern of prostatic urethra, semioval shaped bladder wall. 2. DRUC findings of B.P.H. were spreading of prostaticurethra, spreading, displacement, smooth multidirectional compression of bladder neck, widening of inner orificeof bladder neck, smooth elevation of bladder base, traveculation of bladder wall and variable type of intravesicalstream such as normal, broad, double central stream, associated peripheral umbrella stream and no intravesicalstream. 3. DRUC findings of prostatic cancer were rigidity of prostatic urethra, nodular multidirectionalcompression of bladder neck, multiseptation of peripheral intravesical stream, nodularity of bladder base andtrabeculation of bladder wall. 4. DRUC, which added to double contrast method and postion change of patient,showed more delicate changes of baldder neck, base and wall as well as prostatic urethra in contrast to simpleRUG. We observed that changes of bladder neck and intravesical stream were significant in analzing abnormalenlarged prostate, and could differentiate B.P.H. from prostatic cancer simply by noting sharply demarcatedbladder base.

The question of infectivity and prevalence of Clonorchis sinensis in Cheju province (Quelpart Island) was arisen to authors since the several surveys on the endemic diseases were performed in this island. Therefore, authors decided to solute this question. Then the survey on the possible second intermediate host of Clonorchis sinensis was performed and reported already with negative finding. At present time, authors carried out the collection of all kinds of fresh-water snails through all areas of this island, to confirm the presence or not of Parafossarulus manchouricus, the only first intermediate host of Clonorchis sinensis in Korea . And the following results were obtained. The fresh-water snails collected in the survey were Semisulcospira libertina Gould and Lymnaea ollula Gould. Parafossarulus manchouricus Bourguigant was not collected in this island. It is confirmed that the Clonorchis sinensis can not be prevalent in this island.

PURPOSE: To evaluate the causative factors of the false positive CT findings of parametrial invasions of cervial cancer. MATERIALS AND METHODS: we analysed 17 parametria of 14 patients with the diseases staged over lib on CT, but confirmed to be under stage Ila on pathology. The CT findings were retrospectively reviewed, and compared with pathologic findings. RESULTS: The causes of false postive diagnosis of parametrial invasions on CT were prominent cardinal ligaments (n=12), vaginal fornix(n=3), and prominent uterine vessels(n=2). CONCLUSION: Familiarity with these CT finding may be helpful in avoiding false positive diagnosis of parametrial invasion in patients with uterine cervical carcinoma.

Gastric cancer is the most prevalent gastrointestinal tract malignancy in Korea. By the time the patient hassymptoms, these tumors are usually advanced in stage. In high risk populations,screening such as double contrastUGI or gastric endoscopy is needed and patient with vague symptoms should be studied. However, these screeningshave high diagnostic accuracy rate, only CT scan can identify accurately abnormal stomach wall thickening andintraabdominal tumor extension. And CT is important for palnning of treatment, assessing surgical resectability,postoperative evaluation and prognostic implications. Author reviewed CT scan of 67 cases of confirmed gastriccancer by double contrast UGI or endoscopic biopsy, for 29 months from March 1983 to August 1985 at Department ofRadiology, Pusan National University Hospital. The results were as follows: 1. The most frequent site ofinvolvement of gastric cancer was gastric antrum in 49.9%(33/67). 2. By CT staging, stage 3 was 40.2%(27/67) andstage 4 was 38.8%(26/67). 3. In CT scan analysis, the structures involved by diect invasion were regional lymphnodes, pancrease, and gastrocolic ligament in order of frequency. The structures involved by distant metastaseswere liver, systemic lymph nodes, and mesentery in order of requency. 4. The diagnostic accuracy of CT staging was73.9%(17/23) by correlation of surgical and pathological findings. 5. In determination of stage by CT, the rate ofin accuracy of stage 2 was highest as 33%(2/6), and that of stage 3 was 29.2%(3/11). 6. Of all misdiagnoses,83.3%(5/6) was owing to failure to differentiate lymph node invasion from reactive hyperplasia of lymph node.
