A retrospective study with long term follow-up of Graves' disease patients treated with low activities of 131Iodine.

Background: Previous studies have shown that application of relatively low I-Iodine activities can successfully be used to treat patients with Graves' disease (GD). We assessed treatment outcome in the long-term follow-up of our GD patients and influencing factors.

Methods: We evaluated 521 GD patients in this retrospective clinical single-center study.

Quality-controlled dose-reduction of pelvic X-ray examinations in infants with hip dysplasia.

Background: Digital plain radiography (DR) examinations of the pelvis are frequently performed in infants with hip dysplasia.

Objective: The purpose was to reduce the radiation dose and to determine objective quality control criteria to ensure accurate assessment. This seems feasible because of higher quantum efficiency of DR and easy assessable anatomical structures for most orthopaedic measurements.

Quality-controlled dose reduction of full-leg radiography in patients with knee malalignment.

Objective: Digital plain radiographs of the full leg are frequently performed examinations of children and young adults. Thus, the objective of this work was to reduce the radiation exposure dependent on specific indications, and to determine objective quality-control criteria to ensure accurate assessment.

Materials And Methods: Institutional review board approval and informed consent of all participants were obtained.
