В общей сложности было обнаружено 36 новообразований в надпочечниках, из которых: 10 аденом у 10 пациентов (27,8 %), 5 адренокортикальных карцином у 5 пациентов (13,9 %), 5 феохромоцитом у 5 пациентов (13,9 %), 6 метастатических узлов у 5 пациентов (16,7 %, у 1 пациента были обнаружены 2 метастатических узла в обоих надпочечниках), 4 пораженных надпочечника при лимфопролиферативных заболеваниях с двусторонним поражением надпочечников у 2 пациентов (11,1 %), 2 миелолипомы у 2 пациентов (5,6 %). Были оценены возраст и пол больных, расположение опухоли и ее размеры, а также уровни метаболитов, полученных при мультивоксельной МР-спектрометрии: холин (Cho), креатин (Cr), глутамин/глутамат (Glx), N-ацетиласпартат (NAA), лактат (Lac) и их соотношения Cho/Cr, Lac/Cr, Cho/NAA, Glx/Cr.</p></sec><sec><title>Результаты</title><p>Результаты: Данные МР-спектрометрии позволили нам выявить статистически достоверные различия в группах злокачественных и доброкачественных новообразований надпочечников по содержанию креатина (p = 0,0323). Содержание креатина в доброкачественных образованиях было выше и составляло от 0,415 до 52 ед. (медиана 4,013 ед.), в злокачественных — от 0,221до 16,6 ед. (медиана 2 ед.).</p><p>При пороговом значении содержания креатина меньше 3,42 ед. чувствительность признака в дифференциальной диагностике злокачественных новообразований составила 73,3 %, специфичность – 66,7 %, точность — 79,3 %. Площадь под ROC-кривой (Area Under Curve, AUC) составила 0,703, что соответствует хорошему качеству прогностической модели по шкале экспертных оценок.</p><p>Коэффициент корреляции размеров образований надпочечников и содержания в них креатина по данным МР-спектрометрии составил –0,432. Таким образом, при увеличении размеров опухоли надпочечника содержание креатина в нем пропорционально уменьшается.</p><p>Статистически достоверных различий содержания других метаболитов и их соотношений между злокачественными и доброкачественными новообразованиями надпочечников не было выявлено, равно как и не было выявлено статистически достоверных различий по размеру новообразований, полу и возрасту пациентов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: To improve the differential diagnosis of various adrenal tumors using a two-dimensional (2D) multivoxel 1H-magnetic resonance spectroscopy (MRS) protocol.</p></sec><sec><title>Material and methods</title><p>Material and methods: The study included 32 patients who underwent examination and treatment from February 2021 to February 2022, who, according to various radiation methods of research, had tumor formations in the adrenal glands. In total, 36 neoplasms were found in the adrenal glands, of which: 10 adenomas in 10 patients (27.8 %), 5 adrenocortical carcinomas in 5 patients (13.9 %), 5 pheochromocytomas in 5 patients (13.9 %), 6 metastatic nodes in 5 patients (16.7 %, 1 patient had 2 metastatic nodes in both adrenal glands), 4 affected adrenal glands with lymphoproliferative diseases with bilateral adrenal involvement in 2 patients (11.1 %), 2 myelolipomas in 2 patients (5.6 %). We evaluated the age and sex of patients, the location of the tumor and its size, as well as the amplitude of metabolites obtained by multivoxel MRS: choline (Cho), creatine (Cr), glutamine/glutamate (Glx), N-acetylaspartate (NAA), lactate (Lac) and their Cho/Cr ratios, Lac/Cr, Cho/NAA, Glx/Cr.</p></sec><sec><title>Results</title><p>Results: Malignant formations of the adrenal glands were larger in size compared to benign ones (p = 0.0265). The size of benign formations ranged from 1.4 cm to 8.5 cm (median 3.2 cm), malignant from 2 to 12 cm (median 5.8 cm).</p><p>Statistically significant differences in the groups of malignant and benign adrenal neoplasms were determined by the creatine content detected by MRS (p = 0.0323). Creatine content in benign formations was higher and ranged from 0.415 units to 52 units. (median 4.013 units), in malignant — from 0.221 units to 16.6 units (median 2 units).</p><p>With a threshold value of creatine content less than 3.42 units, the sensitivity of the trait in the differential diagnosis of malignant neoplasms was 73.3 %, specificity 66.7 %, accuracy 79.3 %. The area under the ROC curve (AUC) was 0.703, which corresponds to the good quality of the predictive model on the scale of expert assessments.</p><p>There was a moderate inverse correlation between the size of the adrenal gland formations and the creatine content in it according to MRS (correlation coefficient –0.432). If the size of adrenal neoplasm increase, the creatine content in it is proportionally decrease.</p><p>There were no statistically significant differences in the content of other metabolites and their ratios between malignant and benign adrenal neoplasms, also there were no statistically significant differences in the size of neoplasms, gender and age of patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>надпочечники</kwd><kwd>МРТ</kwd><kwd>магнитно-резонансная спектрометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adrenal glands</kwd><kwd>MRI</kwd><kwd>magnetic resonance spectroscopy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">NIH state-of-the-science statement on management of the clinically inapparent adrenal mass (“incidentaloma”).
