In 110 patients 119 renal transplantations were performed from 1968 until May 1, 1975. In this survey data are given on the recipients and the transplanted kidneys. For the following papers on different complications with renal transplantation the X-ray pictures taken until May 1, 1976 were reviewed and correlated with clinical findings.

The uroradiological changes and complications with 110 patients who did undergo a total of 119 renal transplantations are discussed under the following 4 topographical headings: perirenal and intrarenal, ureter including the anastomosis, bladder, urethra. In our material we found a lymphocele in 1 patient, papillary necrosis in 3, ureteral obstruction in 6, urinary leakage in 23, reflux in a total of 23, renal calculi in 1 and bladder concrements in 1.

An analysis of the results of 252 patients with glottic larynx cancer treated in the RRTI between January 1965 and December 1971 is given. The patients were treated by orthovoltage radiotherapy and classified according to the UICC/AJC staging system of 1972. The 3-year recurrence-free rates for T1, T2 and T3 are 83, 62, and 60%, respectively. The present series suggest a reduction in disease-free survival for T2 patients from 70% with extraglottic extension or partial immobility to 52% with both extraglottic extension and partial immobility.

This paper presents the case history of a female patient with systemic lupus erythematosus, in whom pneumatosis intestinalis developed. The lesions disappeared in response to oxygen therapy. Arteriography revealed evidence of mesenteric arteritis. The patient subsequently developed paralytic ileus with lesions of the intestinal wall, probably based on ischemia as a result of this arteritis.

A case of agenesis of the corpus callosum is described in a 21-year-old male, presenting with epilepsy. Computerized tomographic (CT) scanning was performed using axial and coronal sections. The diagnosis of agenesis was suggested by the presence of an enormous third ventricle, the coronal sections gave the definite proof. In our opinion, biplane CT scan appearances in this condition are characteristic and former investigations (PEG, cerebral angiography) become unnecessary.

In 28 patient with varying degrees of biliary obstruction, the ultrasonic findings were correlated with the serum bilirubin levels and with the size of the bile ducts as measured by percutaneous transhepatic cholangiography (PTC). With ultrasound, study of the intrahepatic ducts achieved the greatest accuracy (71%); examination of common bile ducts and the gallbladder were found to be less sensitive (54 and 53%). Ultrasound proved to be very accurate in biliary obstruction, when the serum bilirubin was above 4.8 mg/100 ml (80 mumol/1).

59 relatives with a family history of hereditary chemodectoma have been successfully screened by means of radionuclide scintiangiography. The findings showed a close correlation with selective roentgenangiography. 3 asymptomatic patients with chemodectoma were revealed by these methods without causing discomfort to the group involved.

Vascular anomalies of the mediastinum which can imitate a tumour in asymptomatic patients, are divided into arterial and venous anomalies. This article discusses the venous anomalies with reference to a number of examples. In all cases, tomography is of value for identification of the anomaly. Angiography is indicated only in selected cases.

An X-ray processing system by computer is described. The scanning device and display are illustrated. The main processing methods are analyzed, in particular the linear and non linear ones. An example of image processing which is the base for future work is shown.
