[Use of nuclear magnetic resonance tomography in the diagnosis of diseases of the central nervous system in children of various ages].

The authors analyse the results of NMR tomography of 48 children (5 mos.-14 years) with various diseases of the CNS system mainly connected with pre and perinatal lesions. High percentage of various disorders in the formation of the brain and spinal cord as the main neurological pathology, is noted. Problems of pathogenesis of atrophic changes of the brain and pathology of corpus callosum are discussed.

[Computed tomography in pre-irradiation topometry applied to diseases of the thoracic organs].

The authors describe methods of pre-irradiation topometry in patients with thoracic tumors. They are based on patients' examination using an X-ray simulator and a computerized tomograph. The superiority of these methods over the previously used conventional methods was shown. The authors presented 77 cases observed by them. Radiation therapy plans in 48% of the patients were changed as a result of pre-irradiation investigation.

[Complex preoperative diagnosis of the dissemination of stomach cancer to abdominal and retroperitoneal organs and tissues].

An analysis of 136 cases of stomach cancer led to the determination of the role and place of gamma-topography, echography, computerized x-ray tomography, angiography and laparoscopy in specified preoperative diagnosis of extra-organ spreading of primary tumors. The informative value and shortcomings of certain methods were shown. A high accuracy of the entire set of diagnostic procedures (94.8%) in the preoperative definition of stomach cancer involvement of the abdominal and retroperitoneal organs and tissues was emphasized.

[Evaluation of the effectiveness of preoperative polychemotherapy of nephroblastomas in children by angiography, ultrasonic tomography and computed tomography].

The results of preoperative polychemotherapy of nephroblastoma in 14 children are presented. Ultrasonic tomography, computed tomography and angiography were performed in all the patients before and after medication. The findings on the efficacy of polychemotherapy were assessed on the basis of surgical evidence and, in particular, resected material examination. A high diagnostic value of all the methods was demonstrated and criteria of the effectiveness of preoperative polychemotherapy as evaluated by application of ultrasonic and computed tomography and angiography were worked out. Optimal terms of carrying out diagnostic procedures in patients with nephroblastoma during preoperative treatment are suggested.

[Computed tomography in the diagnosis of metastases of colon cancer].

The authors present the results of preoperative diagnosis of metastases to the liver and retroperitoneal lymph nodes in colon cancer patients using computerized tomography (CT). Comparing CT and liver scanning the first method proved to be four times more effective. False positive and false negative results in CT were obtained in 11%, in liver scanning in 25.7%. CT made it possible to specify not only the dissemination of a tumor process but also to detect some concomitant diseases. CT can be used for a dynamic control over the efficacy of the treatment of cancer patients.

[Computer tomography in the diagnosis of retroperitoneal nonorganic tumors].

The results of a follow-up of 128 patients with retroperitoneal nonorganic tumors showed that among diagnostic methods computerized tomography (CT) proved to be a valuable method in the recognition of nonorganic tumors of the retroperitoneal space permitting one to detect neoplasms in 92.6%. In spite of the fact that the main bulk of retroperitoneal nonorganic tumors had various images on computerized tomograms this method provided an opportunity to judge of the nature of nonorganic neoplasms on the basis of correlation of their structural elements, the prevalence of this or that tissue and the expression of disintegration processes. Diagnostic errors in CT of the patients with retroperitoneal nonorganic tumors were associated with objective difficulties determined by the peculiarities of interrelationships of a growing tumor with the adjacent organs.
