Description
I tested the following 4 cases:
{'body_region': ['chest'], 'anatomy_list': ['aorta'], 'output_size': [256, 256, 128], 'spacing': [1, 1, 1], 'num_output_samples': 1}{'body_region': ['chest'], 'anatomy_list': ['left lung upper lobe'], 'output_size': [256, 256, 128], 'spacing': [1, 1, 1], 'num_output_samples': 1}{'body_region': ['abdomen'], 'anatomy_list': ['liver'], 'controllable_anatomy_size': [['hepatic tumor', 0.3], ['liver', 0.5]], 'output_size': [256, 256, 128], 'spacing': [1, 1, 1], 'num_output_samples': 1}{'body_region': ['abdomen'], 'anatomy_list': ['spleen'], 'output_size': [256, 256, 128], 'spacing': [1, 1, 1], 'num_output_samples': 1}
For each case, I run inference twice with random_seed = 0, and only case 3 produce same outputs.
Hi @dongyang0122 @guopengf @Can-Zhao , could you help to confirm this issue? Thanks!

- Open a pull request that references the issue number.
Research direction
Start by reproducing the four listed inference cases for the maisi_ct_generative bundle with random_seed = 0, running each case twice and comparing the outputs. Investigate why only case 3 is repeatable; this is complete when the nondeterministic behavior is explained and the affected cases have a verified resolution or documented limitation.
