[Lymphoscintigraphy for non-invasive long term follow-up of functional outcome in patients with autologous lymph vessel transplantation].
Autologous lymph vessel transplantation significantly improves the lymphdrainage in patients with primary and secondary lymphedema. The aim of the present study was to answer the question, whether scintigraphic long-term follow up and semiquantitative evaluation of lymphatic flow could prove the persisting success of this sophisticated microsurgical technique. ⋯ Lymphoscintigraphy combined with semiquantitative estimation of lymphatic transport kinetics has shown to be an easy, reliable and readily available technique to assess lymphatic function before and after autologous lymph vessel transplantation. Thus, the method is not only helpful in planning microsurgical treatment but also in monitoring the postoperative improvement of lymph drainage. Patients with scintigraphic visualization of the vessel graft showed a significant better postoperative outcome than those without. The scintigraphic visualization of the vessel graft therefore seems to indicate a favourable prognosis regarding to lymph drainage.

Comparative StudyTc-99m-tetrofosmin scintigraphy: an alternative scintigraphic method for following up differentiated thyroid carcinoma--preliminary results.
The usefulness of the myocardial perfusion agent, Tc-99m-tetrofosmin (Myoview) in the follow-up of differentiated thyroid carcinoma was evaluated in a clinical study of 15 patients, primary treated with thyroidectomy and high-dose I-131-therapy (2960-3700 MBq). 12 with suspected recurrence and metastases and three patients without any suspicion and compared with other non-specific tracers like TI-201 and Tc-99m-sestamibi. ⋯ In the light of these results, scintigraphy with Tc-99m-tetrofosmin seems to be a possibly sensitive imaging modality in the follow-up of DTC with possible advantages concerning T/Bg ratio, background clearance, detection rate and dosimetry compared with Tl-201 and Tc-99m-sestamibi, especially in patients with elevated Tg level and no iodine uptake, but further investigations are needed to confirm our preliminary results.
