Brief Summary:
The study should evaluate the biological distribution of 99mTc-1-thio-D-glucose in patients with primary brain tumors and recurrence of brain tumors.
The primary objective are:
1. To assess the distribution of 99mTc-1-thio-D-glucose in normal tissues and tumors at different time intervals.
2. To evaluate dosimetry of 99mTc-1-thio-D-glucose.
3. To study the safety and tolerability of the drug 99mTc-1-thio-D-glucose after a single injection in a diagnostic dosage.
The secondary objective are:
1\. To compare the obtained SPECT imaging results of brain tumors with the data of magnetic resonance imaging (MRI) and/or positron emission tomography (PET) and immunohistochemical (IHC) studies of postoperative material.

Detailed Description:
The overall goal is to study the effectiveness of SPECT imaging of primary brain tumors and relapse of brain tumors using technetium-99m labeled glucose.
Phase I of the study:
Biodistribution of 99mTc-1-thio-D-glucose in patients with primary brain tumors and in patients with recurrence of a brain tumor.
The main objectives of the study:
1. To evaluate the distribution of 99mTc-1-thio-D-glucose in normal tissues and tumors in patients with brain tumors at different time intervals.
2. To evaluate dosimetry 99mTc-1-thio-D-glucose based on the pharmacokinetic parameters of the drug after a single intravenous administration.
3. To study the safety of use and tolerability of the drug 99mTc-1-thio-D-glucose after a single intravenous administration in a diagnostic dosage.
Additional research tasks:
1. To conduct a comparative analysis of the diagnostic information obtained in the visualization of brain tumors by SPECT using 99mTc-1-thio-D-glucose with data obtained by magnetic resonance imaging (MRI) and/or positron emission tomography (PET) and immunohistochemical (IHC) research of postoperative material.
2. To study the diagnostic effectiveness of 99mTc-1-thio-D-glucose SPECT in imaging of brain tumors.
3. To evaluate the overall survival of patients with brain tumors depending on the results of 99mTc-1-thio-D-glucose SPECT.
Methodology:
Open-label, exploratory, single centre study. The subjects will receive a single injection of the labelled tracer.
