[Pharmacological modifications of radiation methods for studying the kidneys in determining the nature of the stenosis of the pelviureteral segment in patients with nephrolithiasis. Its outpatient diagnosis].

As many as 17 nephrolithiasis and 6 hydronephrosis patients with surgically verified irreversible (n = 13) and reversible (n = 10) stenosis of the pelviureteral segment were examined. To distinguish the character of the stenosis, use was made of excretory urography and dynamic scintigraphy with progesterone, ultrasound, and dynamic scintigraphy with furosemide. In nephrolithiasis patients, dynamic scintigraphy is less informative as compared to other modifications. As compared to hydronephrosis patients, all the modifications indicated are less informative in nephrolithiasis patients in differentiating the character of the stenosis.

[Scintigraphy in the diagnosis of salivary gland diseases].

An original method of sialoscintigraphy was used to investigate the structure and function of the unchanged salivary glands in 108 patients and in 192 patients with various diseases of the salivary glands (chronic interstitial sialadenitis, chronic parenchymatous sialadenitis, chronic sialadenitis, reactive-dystrophic diseases and tumors. The data obtained are of great importance for the diagnosis and differential diagnosis of salivary gland diseases as well as for the evaluation of effectiveness of therapeutic measures.

Chronic Disease

[Scintigraphy of the thoracic lymph nodes and lungs using Ga-67 citrate in combined examination of patients with sarcoidosis].

Altogether 121 patients with sarcoidosis, stages I and II, were investigated by scintigraphy of the intrathoracic lymph nodes and lungs with 67Ga-citrate, determining angiotensin-converting enzyme activity and using bronchoalveolar lavage. RP accumulation in the lymph nodes was shown to reflect disease activity and was not associated with the spreading and stage of a process in the lymph nodes. A possibility of control of therapeutic efficacy (reduced disease activity, regression of the affected areas, and the appearance of new foci) was shown on the basis of analysis of the results of corticosteroid therapy of 37 sarcoidosis patients.

Adult

[Dynamic scintigraphy of the kidneys using lasix].

Dynamic scintigraphy with lasix (urosemide) in 59 patients with hydronephrosis, nephrolithiasis, chronic pyelonephritis, ureterohydronephrosis on an initial scintigram has shown retention of 99mTc-DTPA in the urinary tracts: an increase or absence of the excretory segment on the activity-time curve up to the appearance of an obstructive type of a curve. Verified operative findings in 19 patients with hydronephrosis and nephrolithiasis have shown a high sensitivity and accuracy of the detection of stenosis of the urinary tracts in the absence of the excretory segment on an initial scintigram irrespective of the fact whether it appears or not on a scintigram after lasix administration. Stenosis of the ureteropelvic segment can be observed in the presence of the excretory segment on an initial scintigram with a prolonged half-period of RP excretion; its 2-fold decrease is noted on a scintigram after lasix administration.

Adolescent

[Test control of student knowledge in radiodiagnosis course].

Various test control tasks to assess the level of self-preparedness for practical work in class, knowledge and skills were shown promising for use in the course of a study of the fundamentals of radiodiagnosis during control of knowledge of 191 students of the medical faculty. With the test control the students reached a necessary level of knowledge. Therefore the authors recommended to use multistage situation problems and test tasks in the course of teaching of combined radiodiagnosis.

[Experience in the use of clinical training games in the teaching of radionuclide diagnosis].

The authors consider the experience in the use of clinical training games as one of the forms of problem-solving teaching that help to prepare students for their future professional activities. The methodology of the games is described: clinical situations, methodological materials, the roles of the game participants, control and correction methods. Clinical training games have advantages over the previous methods of teaching how to solve situational and diagnostic problems.
