[Comparison of the results of Doppler ultrasonography, angiographic scintigraphy and angiography in cases of circulatory disorders in extracranial arteries].

The study was carried out in 122 patients treated for stroke and transient disturbances of cerebral circulation. The results were analysed and compared of blood flow investigations in extracranial arteries by Doppler ultrasonography, radioisotope angioscintigraphy and angiography for the assessment of their clinical value and usefulness. It was found that Doppler ultrasonography was of essential value in the evaluation of the state of the extracranial arteries and for establishing of indications to other studies. However, in cases of slight changes in the studied vessels its value was lower and the method should be regarded as complementary to angioscintigraphy and angiography.
