Effectiveness of Reduced Radioiodine Activity for Thyroid Remnant Ablation after Total Thyroidectomy in Patients with Low to Intermediate Risk Differentiated Thyroid Carcinoma.

Aim: To compare the success rates of radioiodine therapy (RIT) for thyroid remnant ablation (TRA) after the administration of a high-standard activity (3700 MBq; 100 mCi) to a lower-activity regimen of 2000 MBq (54 mCi) I-131 in a cohort of differentiated thyroid carcinoma (DTC) patients (papillary, follicular, mixed, pT1a(m) - pT3, N0 - NX, R0).

Methods: 135 patients received approx. 2000 MBq I-131 (54 mCi) for thyroid remnant ablation after total thyroidectomy for DTC, 137 patients received approx.

Validation of several SUV-based parameters derived from 18F-FDG PET for prediction of survival after SIRT of hepatic metastases from colorectal cancer.

Unlabelled: (90)Y radioembolization (selective internal radiation therapy [SIRT]) is a valuable therapeutic option for unresectable hepatic metastases arising from primary colorectal cancer. The present study evaluated the prognostic value of (18)F-FDG PET/CT metabolic parameters for predicting survival after SIRT.

Methods: Eighty patients with hepatic metastases of colorectal cancer were treated with SIRT.

F-18-fluoro-2-deoxyglucose positron emission tomography/computed tomography in the follow-up of breast cancer with elevated levels of tumor markers.

Objective: The value of combined positron emission tomography (PET)/computed tomography (CT) in the follow-up of patients with breast cancer with elevated tumor markers but without proven metastases or local recurrence was assessed.

Methods: Thirty-four women underwent PET/CT. The PET and CT images were first analyzed separately; fused findings were then interpreted, blinded to the results of the other modalities.
