The effects of a custom-made lead collar on dose rates of patients treated with 131I.

We studied the effects of a custom-made lead collar on dose rates and hospitalization days of patients treated with high doses (>400 MBq) of radioiodine (131I). Between October 2005 and March 2006, the dose rates of 28 consecutive patients were studied. Dose rates of patients with and without the collar (5.

Indium-111-Octreotide scintigraphy in differentiated thyroid carcinoma metastases that do not respond to treatment with high-dose I-131.

Aim: Differentiated thyroid cancer is characterized by a very good prognosis in the majority of the patients. The therapy of choice is surgery followed by ablation with Iodine-131 (I-131). However, some patients have metastases that have lost the capability of concentrating I-131, even when it is given in therapeutic doses.

Scintigraphic head-to-head comparison between 99mTc-WBCs and 99mTc-LeukoScan in the evaluation of inflammatory bowel disease: a pilot study.

Scintigraphy with technetium-99m labelled white blood cells (WBCs) is routinely used in our hospital for the assessment of inflammatory bowel disease (IBD). The main disadvantages of this diagnostic tool are its time-consuming nature and the handling of blood itself. 99mTc-LeukoScan is a relatively new, easily prepared agent that is used for the detection of osteomyelitis.
