Design outcomes

Primary

Measure	Time frame
Usefulness of IMP-SPECT imaging and its fusion images with CT or MRI, and IMP SPECT semi-quantitative evaluation method. 1) diagnostic ability of choroidal tumor, 2) local control rate, and 3) disease-free recurrence period.	—

Secondary

Measure	Time frame
Correlation among semi-quantitative evaluation methods such as SUV of IMP SPECT, tumor size, and the presence or absence of distant metastasis.	—
