Data concerning the aetiology are especially important to the parents, who need information on the risk of recurrence for future pregnancies. During 1980-1982 a postmortem radiologic investigation was carried out on 514 perinatally dead infants from 22 hospitals in Finland. Pathologic radiologic findings were seen in 30 per cent of the material. Ninety-nine cases had congenital defects, while the rest showed other skeletal or soft tissue abnormalities. Of those with congenital defects, there were 6 osteochondrodysplasias, 16 chromosomal malformation syndromes, 13 autosomal recessive inherited malformation syndromes and 18 multiple malformation syndromes of unknown aetiology. There were also 18 cases with malformation sequences and 10 single malformations with abnormal radiologic findings. Congenital defects due to disruptions were detected in 12 cases and defects due to deformations in 7. The present article includes a review of the radiologic findings in 514 cases, with special reference to the skeletal findings.","PeriodicalId":7142,"journal":{"name":"Acta radiologica: diagnosis","volume":"27 5","pages":"481-94"},"PeriodicalIF":0.0,"publicationDate":"1986-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/028418518602700501","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14917890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Films from 152 consecutive patients (examined with conventional abdominal films, urography/tomography) were analyzed independently. With respect to the number of patients with or without calculi there was agreement between the three observers in 129 of the 152 cases, which was taken to represent very good agreement beyond chance. The total number of stones was interpreted as 832, 460 and 570 respectively, and the median stone size as 6, 9 and 11 mm2. There was a fair interobserver agreement rate regarding whether stones were localized to the renal parenchyma or calyces, and whether stenosis/stricture or hydronephrosis was present. Tomography appeared to reduce the interobserver variability significantly. Adequate bowel cleaning, oblique projections, and lack of clinical information apparently did not influence the agreement rate. It was concluded that such interobserver variations are factors of importance in the reliability of the radiologic evaluation of urolithiasis.","PeriodicalId":7142,"journal":{"name":"Acta radiologica: diagnosis","volume":"27 5","pages":"561-4"},"PeriodicalIF":0.0,"publicationDate":"1986-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/028418518602700514","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14916568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MDP and Hippuran renograms showed in general the same pattern and there was no difference between the kidney function determined with the two radionuclides. The peak of the MDP curves occurred later and was less distinct than that of the Hippuran curves. The residual activity of the kidneys 20 min after the injection was higher on the MDP renograms compared with the Hippuran renograms. The early sequential MDP images were superior in quality to the Hippuran images and to the renal images obtained at bone scintigraphy. The early MDP images correlated well with the findings at urography performed in 12 patients, as all cases of radiologically diagnosed hydronephrosis, reduction of renal parenchyma and renal mass lesions became demonstrated. Renal calculi were only diagnosed at urography. In conclusion, MDP cannot replace Hippuran as a renal radionuclide agent, mainly due to its lower extraction ratio and the high bone uptake. However, an increased use of early dynamic renal imaging is recommended in urologic patients referred to bone scintigraphy as valuable information about renal function may be obtained by this procedure.","PeriodicalId":7142,"journal":{"name":"Acta radiologica: diagnosis","volume":"27 5","pages":"565-8"},"PeriodicalIF":0.0,"publicationDate":"1986-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/028418518602700515","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14916569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One hundred and sixty-five of 167 patients (99%) were recorded radiologically as having a gastric lesion. The initial diagnosis was carcinoma in 144 patients (86%), and benign lesion in 21 cases (13%). In 2 cases (1%) no abnormalities were seen. In 3 out of 9 patients with a partial gastrectomy (33%) an incorrect diagnosis was made. In 11 of 12 patients with early gastric cancer the radiologic examination revealed abnormal findings, but 7 of these were incorrectly interpreted as benign. A retrospective analysis of the radiologic examination in which no malignancies were reported showed that inadequacy of the examination technique and misinterpretation of radiologic signs of malignancy were the main causes of failure in diagnosing of malignancy. The rate of misinterpretation of malignancy as a benign lesion (13%) justifies the endoscopic control of every radiologically detected abnormality. The high sensitivity in detecting a lesion indicates, however, that a biphasic radiologic examination is a safe screening method in gastric cancer. Endoscopy with biopsy showed a lesion in 156 out of 160 patients (98%), but in 11 of these (7%) the initial examination did not yield histologic proof of malignancy. In 4 patients (2%) no abnormalities were observed by endoscopists. One hundred and forty-nine patients were examined with both radiology and endoscopy with biopsy. A malignant lesion with recognition of its malignant character was defined in 144 cases (97%).","PeriodicalId":7142,"journal":{"name":"Acta radiologica: diagnosis","volume":"27 5","pages":"547-52"},"PeriodicalIF":0.0,"publicationDate":"1986-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/028418518602700511","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14917523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gallbladder was drained following simple needle puncture in six cases while a drainage catheter was inserted in seven. A premedication of 0.5 mg of atropine and 50 mg of pethidine was given. The gallbladder became decompressed in all cases, and pain was instantly relieved. Impacted stones were freed from the cystic duct in two cases and from the papilla of Vater in another two cases. The patients' condition improved and elective cholecystectomy was performed in four cases, while a further three patients await surgery. In five cases the acute stage of the disease subsided; surgical treatment was refrained from because of gallbladder carcinoma with metastases in one patient and other diseases in the remainder. One patient died of gastric carcinoma. One patient with ischemic heart disease had systemic hypotension for six hours after the drainage and one had slight haemorrhage for four hours. No other complications were noted. In addition, the procedure was also carried out as a diagnostic study in one patient in whom the site of bile leakage was determined by filling the biliary tree with contrast medium from the gallbladder. Guided aspiration and percutaneous drainage of the gallbladder is helpful in patients with severe acute cholecystitis attended with a high surgical risk.","PeriodicalId":7142,"journal":{"name":"Acta radiologica: diagnosis","volume":"27 5","pages":"543-6"},"PeriodicalIF":0.0,"publicationDate":"1986-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/028418518602700510","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14664192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
