摘要：
FIELD: medicine.SUBSTANCE: invention refers to biology, medicine, nuclear magnetic resonance (NMR) diagnosing, and can be used for the qualitative assessment of the fat content of a long-length biological object, in particular humans. The method is implemented with the use of a magnetic resonant tomography scanner that provides a multilayer transversal body scanning from one end to the other, with the biological object movable discretely longitudinally at a pitch equal to a scanning layer thickness. The layer size is specified if providing a magnetic field uniformity within this layer. The NMR signal spectra are recorded in layers, and the NMR signal spectra received by the magnetic resonant tomography scanner are summed, while the qualitative assessment of the fat content in the biological object is made by water to fat peak relation in the summed spectra.EFFECT: invention provides the express analysis and accuracy of the qualitative assessment of the fat content in the long-length biological object, such as a human by better tissue specificity, high sensitivity to recorded signal, high rate measuring and obtaining the spectroscopic data with the use of common typical tomography equipment without the need of MRT imaging, with obtaining the chemical shift data without using the gradient fields, provided the magnetic field uniformity space is inadequate for enclosing the entire biological object with relaxation in the requirements for the number and thickness of the scanned sections.3 dwg, 1 exИзобретение относится к биологии, медицине, диагностике методом ядерного магнитного резонанса (ЯМР), и может быть использовано для количественной оценки содержания жировой ткани всего тела длинномерного биологического объекта (БО), в частности, человека. Способ осуществляют с помощью магнитно-резонансного томографа - проводят послойное сканирование тела в поперечном направлении от одного конца тела к другому, при этом БО дискретно перемещают в продольном направлении с шагом, со
