"1a: improvement due to decreasing tumour burden"
"1b: improvement due to medication effect"
"BT-RADS 2: no change"
"BT-RADS 3: imaging worsening (indeterminate/likely progression): worsening imaging findings."
"3a: worsening due to treatment effects"
"3b: indeterminate mix"
"3c: favour increasing tumour burden"

"may also involve specified new lesions located outside the radiation therapy treatment area."
"1a, 1b, and 2: continued regular follow-up."
"3c: consider decreased follow-up time or a change in management."
"Brain Tumour Reporting and Data System (BT-RADS) is a tool that was introduced in 2018 as a tool for reporting and classifying post-treatment gliomas 1. The primary objective of BT-RADS is to provide a standardised, management-based reporting system 2,3."

"BT-RADS was specifically developed for the reporting and classification of post-treatment gliomas, particularly high-grade gliomas such as glioblastoma, which are characterised by high recurrence rates."
"It has, however, to date had limited penetration into routine clinical practice, with older systems (e.g. the MacDonald criteria for glioblastoma, Response Assessment in Neuro-Oncology (RANO)) remaining more widespread 4."
"BT-RADS employs a numerical scoring system ranging from 0 to 4, which includes several sub-categories: 1a, 1b, 3a, 3b, and 3c. Each score and sub-category is directly linked to straightforward management recommendations."

"BT-RADS 1: imaging Improving"
"BT-RADS 2: no change"
"BT-RADS 3: imaging worsening (indeterminate/likely progression): worsening imaging findings."
"BT-RADS 4: worsening highly suspicious for tumour progression"
"Studies consistently demonstrate that BT-RADS exhibits good to very good inter-rater reliability, indicating its consistent application across different interpreters 1-4. Agreement is consistently highest for stable or improving cases and decreases for cases indicating worsening conditions 2."
