[Magnetic resonance in the neuroradiologic diagnosis of syringomyelia]. / Magnetska rezonancija u neuroradioloskoj dijagnostici siringomijelije.

Syringomyelia is the chronic progressive disease which etiology has still been discussed. The diagnosis and differential diagnosis of all SM types using magnetic resonance as specific and most sensitive method of examination have been presented in the study for the first time in our country. In two-year period since the introduction of this examination method in our Institute we examined 25 patients with 3 primary congenital and 22 with secondary SM, among whom 15 had post-traumatic and 7 had traumatic forms. All the changes characteristic for syringomyelia in neuroradiologic diagnosis were described in details. Magnetic resonance is primary and superior neuroradiologic method in all spinal processes for the discovery of neurologic, undefined myelopathic changes, such as SM. The methods of micro-surgical operative treatment are not the subject of this study.

[Neuroradiologic diagnosis of space compression processes caused by orbital tumors or pseudotumors]. / Neuroradioloska dijagnostika spaciokompresivnih procesa orbite tumorske i pseudotumorske etiologije.

In thirty-year period are presented 110 patients with spatio-compressive orbital processes diagnosed by ophtalmoradiological methods. Out of those, 100 patients were surgically treated and histopathologically verified in our institution. All the entities of spatio-compressive processes are presented, benign and malignant tumors as well as pseudotumors of inflammatory and vascular nature. All the methods known in the world up to day are chronologically alleged, from classic to modern digital methods, as well as their diagnostic efficacy. The most efficacious algorhitm is established in the choice of radiological examination procedures on the basis of former experience. The collaboration of neuroradiologist, ophthalmologist and neurosurgeon was of the utmost significance in solving the spatio-compressive orbital processes.

[Closed intracranial extradural traumatic lesions of the internal carotid artery]. / Zatvorene traumatske intrakranijalne ekstraduralne lezije unutrasnje karotidne arterije.

Closed intracranial lesions of the internal carotid artery are severe complications of craniocerebral trauma. Intradural lesions of branches of this artery are common and well known while extradural lesions are less frequently found. This is illustrated also by a small number of lesions found in our patients within the twenty-year period, namely 8/1000 compared to intradural lesions of branches of the internal carotid artery. Traffic accidents are dominating in their etiology and the causative mechanism is transsphenoidal fracture of the skull base. Due to difficult surgical approach inadequate methods of ligature of the extracranial portion of the internal carotid artery have been used before but it has not led to cure. Contrarily to this, modern direct microsurgical approach or balloon embolisation successfully solve this problem.

[Patient irradiation in the radiodiagnostic use of ionizing radiation. Present status and prevention]. / Ozracivanje bolesnika u radiodijagnostickoj primeni jonizujuceg zracenja. Danasnje stanje i preventiva.

Tabelar presentation of measurement results for adult patients irradiation by thermoluminescent dosimeters is given for classic and standard computed-tomographic radiodiagnostic procedure. Measurements have included not only somatic organs irradiation, but critical organs (sternum, gonads and eye lens) thyroid gland and uterus, as well. They have always been undertaken under the same conditions by modern multipulse X-ray apparatus with electronic X-ray image amplifier, iontomat and standard screens. Results have shown considerable exposition and overdosage in relation to annual standard limits so that risk in this branch of diagnostics has exceeded limits of acceptable tolerance. Failures in practice, necessary medical and technical protective measures as well as positive regulations in the law of ionizing irradiation protection have been pointed out.
