METHOD FOR TOPICAL DIAGNOSTICS OF INFLAMMATION IN HEART Russian patent published in 2017 - IPC A61B6/03 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, radiologic diagnostics, and can be applied in cardiology and cardiosurgery. Topical diagnostics of inflammation in heart is carried out by performing single-photon emission computed tomography (SPECT) 18-20 hours after intravenous introduction of radiopharmaceutical. Superficial radioisotope label is applied on patient's body in 3 intercostal space on the left on midclavicular line before tomography. After that, disposable ECG-electrode is stuck to it as radiopaque marker. SPECT registration is realised in 27 projections simultaneously, time of scanning constitutes from 4000 to 600 sec depending on patient's body weight. After fininshing SPECT, high resolution X-ray computed tomography of chest with cut depth 1.25 mm is performed without changing position of patient's body and height of tomographic table on hybrid SECT/CT tomograph. After that, superposition of scintigraphic and X-ray tomographic images is performed by markers by precise overlaying on each other radioisotope and radiopaque markers in frontal, sagittal and transverse cuts with determination and location of inflammatory focus in heart.

EFFECT: method provides high sensitivity and accuracy of determination of presence and location of inflammation foci in heart, eliminating errors in the process of superposition of images with visualisation of all heart chambers, reduction of examination time, and reduction of radiation load on patient.
