[en] A collection was made of 33 computerized tomography scans of the normal anatomy of parotid glands showing the relations to adjacent anatomical structures. For scanning, the Lipiodol UF contrast medium was used. The collection represents a valuable tool for assessing parotid gland pathologies. (author). 9 figs., 4 refs

[en] The experience is presented gained with the application of computerized tomography (CT) in maxillofacial surgery. CT has been found to be a valuable diagnostic method allowing to differentiate between inflammations, abscesses and neoplasms. It provides information on the loci of pathological processes and helps identify the nature of the processes. It has most frequently been used in perimaxillary abscesses, in maxillary sinus pathologies, in the jaw bone disease, in maxillofacial injuries, in neoplastic diseases and in sialotomography. It has not, however, been found to be the method of choice in this discipline but only an invaluable complementary diagnostic method which should be used discriminately and in cases where more information is needed than provided by conventional X-ray radiography and other classical methods.

[en] A relation of the tumor to the facial nerve was assessed in 38 patients with parotid tumors using CT sialography. The relation was found to exist in 29 patients. In 83% of these patients the CT finding agreed with surgery findings, in 17% it did not. In 9 patients (24%) the relation between the two structures could not be determined.

[en] The experiences are described of the examination of orbita in children using computer tomography (CT). Over a period of four years 42 examinations were performed of children in the age ranging between 7 months and 15 years, i.e., 2.7 per cent of all CT examinations performed. The highest diagnostic yield was in orbita tumours. The possibilities of CT are demonstrated on examples. (author)

[en] Computer tomography was used in 42 patients for the exploration of ventricular and subarachnoidal spaces following intraventricular, lumbar or suboccipital injections of 3 to 5 ml Amipaque using the kind of manoeuvre to permit optimum filling of the region concerned. This type of CT ventriculo- or cisternography is a significant supplement to plain CT examination particularly because it supplies data on the causes of CSF passage blocks. Thus, in two female patients it proved possible to localize cysts in the 3rd ventricle, the density of which was no different from that of CSF. As regards benign stenoses of the aqueduct, it is likely to yield less information than conventional specific ventriculography. On the other hand, the technique gives perfect visualization of all possible communications between pathological intracranial cavities and the ventricular system. CT cisternography proved useful for the identification of small-size isodense growths in the region of the sella turcica, and brought convincing evidence of the causes of profuse liquorrhea by demonstrating the presence of nasal meningocele. It was also found helpful in the analysis of the craniocervical region, otherwise difficult to survey. (author)

[en] The contribution of computerized tomography is evaluated from three angles. Discussed are: the adjustment of the health facility to the possibilities and capacity of CT, i.e., the immediate use of the diagnosis; the economy of CT operation and its retroactive effect on the efficacy of the health facility; the role of the engineer and his position at the respective workplace and the technical service organization.

[en] New diagnostic methods, such as angiography, cisternography by contrast media, and computerized tomography are described and the results shown for a group of fifty patients who had tumours directly affecting the temporal bone and who were examined and operated on in a neurosurgical clinic. Arteriography and jugulography yield essential information on the extent of these greatly vascularized tumours and also on the obstructions of the cervical part of the carotid artery and v. jugularis in tympanojugular chemodectomas in which CT is less applicable. Computerized tomography is now a method of choice for intracranial tumours and it is suitably supplemented by vertebral and/or carotid arteriography. Cisternography by Myodil is of primary importance not only in small intracanalicular neurinomas, but also in those tumours in the region of pontocerebellar angle where CT would be negative or where any other methods only yield controversial results. Imaging the skeleton of the skull base continues, however, to maintain its value whereas pneumoencephalography and ventriculography recede into the background. (author)

[en] 53 cranial computed tomographic scans were performed and the contribution of this new radiographic method is emphasized to ophthalmologic diagnosis, especially to the differential diagnosis of proptoses and orbital lesions. Computerized tomography is a noninvasive method easily tolerated by patients. Rapid diagnosis and exclusion of pathological processes shorten. The duration of the hospital treatment of patients.

[en] From a one-year operation of the only computerized tomography unit in the country so far a great deal of medical, technical and economic experience was gained that can be usefully applied in the planned extension of the network of these units in Czechoslovakia. These findings may influence the choice of the type of apparatus as well as the organization of its operation. Also an attempt was made to express the expenses per examination in our conditions. The medical sphere confirms the top position of this method in neuroradiological diagnosis and also its great usefulness for other regions than the head. (author)

[en] CT (computerized tomography) sialography ions used for imaging 40 tumors of the parotid gland. The obtained sialographic pictures were divided into five groups. By comparison of the frequency of malignant and benign tumors in different groups, CT sialography was shown to differentiate in more than half the cases these biologically differing lesions. CT sialography provided in all cases information on the site of the tumor and mostly also on its size. (author). 6 figs., 7 tabs., 10 refs
