[Computed tomographic findings in carpal tunnel syndrome].

Morphometric measurements of the carpal bones were carried out in 32 patients with carpal tunnel syndrome (CTS) and in 47 normal persons, using high resolution CT. Measurements of distances and areas were carried out at the entry of each carpal tunnel and at its narrowest point. In idiopathic CTS there were no significant differences in these measurements from normal carpal measurements. The situation was different in ten patients with nonidiopathic CTS; in these CT showed the cause of median compression reliably. Our results suggest that there are no indications for performing CT of the wrist in idiopathic CTS, but that valuable information may be expected from CT in cases of nonidiopathic CTS.

[Morphometry using computerized tomography of the wrist in idiopathic carpal tunnel syndrome. Comparison of pre- and postoperative findings].

Alteration of carpal morphometry after surgical release of the carpal tunnel was investigated in 22 patients with idiopathic carpal tunnel syndrome, using pre- and postoperative computed tomography. The morphometric evaluation showed an increase in carpal volume which was due to a palmar soft-tissue prolapse in 90% and to an increase of the carpal arch cross sectional area in about 10%. The carpal tunnel release caused a palmar opening of the canal most commonly at the pisiform bone. There was also a variation in form and an increase in volume of Guyon's canal. The results are discussed and related to the postoperative complaints.

[Computerized tomography diagnosis of acetabulum fractures].

One hundred and ten acetabular fractures in 102 patients were examined by CT. In 78% there was agreement with the findings on conventional radiological examination. CT altered the classification of fractures, particularly if these were complex. CT was superior to conventional radiology for demonstrating the course of the fractures and for identifying local complicating factors. In 68 surgical explorations, specificity of CT was found to be 97%. After the age of 40 there was a tendency for complex fractures. Analysis of the fractures in three dimensions often determines the need for surgical treatment, particularly if the weight-bearing portion of the acetabular roof and the posterior bony column has been fractured.

Computed tomography of adult ileocolic intussusception.

Computed tomographic evaluation of ileocolic intussusception in an adult is presented. Upper gastrointestinal series with orally administered water-soluble contrast agent suggested obstruction in the lower part of the small intestine, but computed tomography made a definitive diagnosis. Pathognomonic CT findings of ileocolic intussusception are presented.

[Comparative roentgen study of the small intestine with single and double contrast].

The experiences from a total of 303 small intestine examinations of different techniques show that especially the double-contrast representation using barium sulfate and air achieves the best diagnostical findings. The double-contrast representation can be achieved by an antegrade small intestine enema (enteroclysis) or within the conventional small intestine passage by retrograde air insufflation. These examination techniques make optimal fine diagnostics especially of the lower ileum possible. The indications for the different methods are explained.

[Radiological biliary tract diagnosis after cholecystectomy (author's transl)].

Fifty-three patients with biliary symptoms were studied at least four years after cholecystectomy by isotope techniques. There was a highly significant correlation between symptoms and disturbances of bile flow, such as dyskinesia or obstruction. There was no correlation with serum enzyme levels such as gamma-GT, alkaline phosphatase, bilirubin or transaminases. Measurements of the diameter of the bile duct on cholangiograms provided no evidence of obstruction up to 15 mm., although a diameter in excess of 10 mm, made obstruction likely. The upper value for "normal" bile flow derived from hilar flow curves of patients without dyskinesia showed a half value period of 27.5 minutes. The disturbances of flow demonstrated by isotope methods in the presence of typical symptoms, and without other pathological findings, indicate a pre-clinical stage of a partly compensated bilio dynamic insufficiency. Where there is no morphological evidence of biliary obstruction, one must assume inflammatory changes round the papilla of Vater; these are frequent even in normal biliary tracts and almost always present after cholecystectomy. Quantitative hepato-biliary scintigraphy is the most reliable method for objective measurement of disturbances of bile flow and make it possible to avoid the vague diagnosis of "post-cholecystectomy syndrome".

[Radiological investigation of the bile ducts following cholecystectomy. Paper III: Determination of the diameter of the common bile duct by isotope methods (author's transl)].

The diameter of the common bile duct can be determined by means of quantitative hepato-biliary functional scintigraphy to an accuracy of +/- 2 mm. It is necessary to keep the conditions of the test constant, such as constant regions of interest and size of region. A common bile duct diameter greater than 10 mm. is suggestive of biliary obstruction, diameters above 15 mm. are definite proof. For the demonstration of post-hepatic obstruction, the hilar flow curve is confirmatory. Peristalsis of the common bile duct, which is an unlikely phenomenon in view of the anatomic studies of the muscle in the bile duct, cannot be demonstrated in this way.
