Computed tomographic (CT) scans were acquired on a GE Medical Systems Light Speed Plus CT scanner in helical mode. Images were reconstructed with 1-mm overlapping slice thickness and a 1-mm interval. Lesion volume was determined from CT scans by manual tracing using the Analysis of Brain Lesion (ABLe) software52 (link),53 (link) implemented in MEDx (Medical Numerics Inc, Sterling, Virginia) with enhancements to support the Automated Anatomical Labeling atlas. The tracing was performed by a trained neuropsychiatrist and then reviewed by J.G., an experienced observer, who was blind to the results of the clinical evaluations. A consensus judgment determined the final outline of the lesion. On the basis of the lesion volume, we determined the percentage of volume loss [lesion volume (cm3) × 100/total brain volume (cm3)].

CT scans were obtained with a 64-detector row scanner (Light Speed VCT XT; GE Healthcare, Milwaukee, WI, USA), using the enhanced helical technique (40 mA, 120 kVp, beam width of 10 20 mm, beam pitch of 1.375 1.5). For an enhancement study, 100 mL of contrast medium (Iomeron 300; Bracco, Milan, Italy) were administered intravenously. Lymph nodes with a short-axis diameter of more than 10 mm were considered positive for malignancy. If lymph nodes contained nodular or laminated calcification, they were regarded as benign, regardless of size (20 (link)).
Image acquisition of integrated PET/CT was performed using a PET/CT device (Discovery LS, GE Healthcare, Milwaukee, WI, USA) that consisted of an Advance NXi PET scanner and an eight-slice Light Speed Plus CT scanner. After fasting for at least 6 h before the PET/CT examination, patients received an intravenous injection of 370 MBq of 18F FDG and then rested for 45 min before imaging. Lymph nodes were considered positive for malignancy if the maximum standardized uptake value (SUVmax) was more than 2.5 on 18F FDG PET/CT (21 (link)).

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.
