The purpose of the current study was to investigate the diagnostic performance of F-18 fluorodeoxyglucose (FDG) PET or PET/computed tomography (PET/CT) for detection of post-transplant lymphoproliferative disorder (PTLD) through a systematic review and meta-analysis. ⋯ The current meta-analysis showed the high sensitivity and specificity of F-18 FDG PET or PET/CT for the detection of PTLD. At present, the literature regarding the use of F-18 FDG PET or PET/CT for the detection of PTLD remains limited; thus, further large multicenter studies would be necessary to substantiate the diagnostic accuracy of F-18 FDG PET or PET/CT for the diagnosis of PTLD.

Meta Analysis Comparative Study
Value of 18F-FDG PET versus iliac biopsy in the initial evaluation of bone marrow infiltration in the case of Hodgkin's disease: a meta-analysis.
We carried out a meta-analysis to evaluate the performance of 2-deoxy-2-[(18)F]fluoro-D-glucose ((18)F-FDG) PET and PET/CT against bone marrow biopsy (BMB) in the initial diagnosis of bone marrow infiltration (BMI) in patients with Hodgkin's disease (HD). ⋯ (18)F-FDG PET significantly outperforms iliac BMB in the detection of BMI in the initial staging of HD patients and therefore should be used as a first-line study. Iliac BMB has low sensitivity and a high rate of false-negative findings. Thus, a negative BMB finding cannot rule out marrow involvement in HD patients on initial staging.

Meta Analysis
Thyroxine alone or thyroxine plus triiodothyronine replacement therapy for hypothyroidism.
Standard therapy for patients with hypothyroidism is replacement with synthetic thyroxine (T4). However, thyroxine plus triiodothyronine (T3) replacement therapy resulted in marked improvements in several items of the Profile of Mood States and in a few indices of psychometric function and quality of life. The adequacy of thyroxine alone versus thyroxine plus triiodothyronine to treat hypothyroidism has yielded conflicting results. ⋯ In conclusion, on the basis of data from recent studies, we conclude that combined T4 and T3 treatment does not improve well-being, cognitive function, or quality of life compared with T4 alone. T4 alone may be beneficial in improving psychological or physical well-being. According to the current evidence, T4 alone replacement may remain the drug of choice for hypothyroid patients.

Meta Analysis
Value of 18F-FDG-PET/PET-CT in differentiated thyroid carcinoma with radioiodine-negative whole-body scan: a meta-analysis.
The aim of this study was to evaluate the diagnostic accuracy of 18F-fluorodeoxyglucose-PET (FDG-PET) and FDG-PET/computed tomography (CT) in the detection of recurrent or metastatic differentiated thyroid carcinoma (DTC) that was not identified by radioiodine whole-body scintigraphy (WBS). ⋯ FDG-PET is especially effective in detecting patients with elevated thyroglobulin levels and normal radioiodine WBS; FDG-PET/CT is a more sensitive method in the follow-up of thyroid cancer recurrence or metastases, particularly in those with negative WBS.
