Inclusion criteria

Inclusion criteria: Patients underwent GSA SPECT and MRI among those who were / will be treated with carbon ion radiotherapy for liver tumors from December 2018 to September 2024 at QST hospital.

Exclusion criteria

Exclusion criteria: Patients who refuse to participate in this study. However, if the request is made after the opt-out period and the data has already been used for analysis, it may not be excluded.

Design outcomes

Primary

Measure	Time frame
Assessment of diagnostic abilities of GSA SPECT or MRI in terms of prediction of residual liver reserve capacity before and 3 months, 1 to 5 years after carbon ion radiotherapy	—

Secondary

Measure	Time frame
Correlation among overall survival rate, treatment completion rate in intent to treat group, liver function indices such as Child-Pugh classification and other clinical data, and radiation dosimetry estimation.	—
