All subjects were asked to fast for at least 6 h, but had free access to water before PET imaging. PET scans were performed with a United Imaging uMI510 PET/CT (United Imaging, Shanghai, China) in three-dimensional (3D) mode. A CT transmission scan was first performed for attenuation correction. The emission scan was acquired between 60–70 min after intravenous injection of 185 MBq of ¹⁸F-fluorodeoxyglucose. The imaging data was digitally registered onto a computer disk to create the sectional images of a patient’s brain [23 (link)]. As no arterial blood sampling was taken in this clinical imaging protocol, we used radioactivity images to measure changes in relative regional glucose metabolism. All studies in patients and normal individuals were performed in a resting state in a quiet and dimly lit room. All patients and normal individuals were monitored via cameras during the course of uptake and scanning procedure.

Targeted I-125 Brachytherapy for Tumors

Patients in the TAI combined treatment group received arterial infusion combined with ablation or radioactive particles. For radioactive I 125 particle implantation in the TAI combined treatment group, patients rst underwent CT (uMI-510 PET-CT, United Imaging, Shanghai, China), and the images were entered into a treatment plan system (TPS, Astro Tech Ltd, Beijing, China). The gross tumor volume (GTV) was con rmed by analysis of the scans by a medical specialist, and 0.5-1.0 cm was added to the boundary of the GTV to include the periphery of the tumor. Then, implantation of I 125 radiological particles (radioactivity, 0.55-0.75 mCi; dose, 120-140Gy; dose rate, 0.05-0.10Gy h21; half-life, 59.6 days; effective radius, 1.72 cm; Zhibo Bio-Tech Ltd, Beijing, China) was performed at the periphery of the tumors. The radioactive dose was evaluated 1 week after implantation, and a D90 (the dose to 90% of the volume) of 60-140 Gy was expected. If the actual dose was lower than this, implantation could be repeated.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
