NCT05087134

Brief Summary

It was reported that TSC2-deficient cells enhance phosphatidylcholine synthesis via the Kennedy pathway. 11C-Choline can reflect the metabolic process of choline in vivo by intravenous injection. The purpose of this study is the ability of 11C-Choline PET/CT to evaluate the baseline condition of LAM patients and the efficacy of rapamycin after treatment.

Outcome Measures

Primary Outcomes (1)

  • Standardized uptake value of 11C-Choline in LAM lesions

    The semiquantitative analysis will be performed by the same person for all the cases, and the standardized uptake value (SUV) of the tracer in lymphatic lesion will be measured.

    through study completion, an average of 2 year

Study Arms (1)

11C-Choline PET/CT for Lymphangioleiomyomatosis (LAM)

EXPERIMENTAL

The patients were injected with 11C-Choline of 5-10mCi and underwent PET/CT scan 20\~40min after the injection.

Drug: 11C-Choline

Interventions

11C-Choline were injected into the patients before the PET/CT scans
