Clarification Regarding Test Data Modality

Could you please clarify the MRI modality used in the test set for each task? Specifically, I would like to know whether the test data for Task 1 (Diagnostic MRIs) consists only of T1-weighted arterial phase images, or if it includes other sequences as well.

The test sets match their respective annotated training sequences:

• Task 1: T1W contrast-enhanced arterial-phase images.

• Task 2:T2W MR-Linac scans.
