Impact of SPECT and integrated low-dose CT after radioiodine therapy on the management of patients with thyroid carcinoma.

Aim: To determine the value of single photon emission computed tomography (SPECT) with integrated low-dose computed tomography (CT) for the interpretation of inconclusive foci in planar I whole-body scans after radioiodine therapy.

Methods: Twenty-five patients with inconclusive findings in planar scanning after ablative radioiodine therapy (3.7 GBq I) due to differentiated thyroid cancer were included.

Influence of fast lymphatic drainage on metastatic spread in cutaneous malignant melanoma: a prospective feasibility study.

The concept of sentinel lymph node biopsy in cutaneous malignant melanoma is widely established. Preoperative cutaneous lymphoscintigraphic mapping is a reliable method for identifying the nodal basins at risk of metastases in melanomas. In this prospective study we investigated the correlation between the scintigraphic appearance time and the metastatic involvement of sentinel lymph nodes.

Electron beam computed tomography and ventilation perfusion scintigraphy in the diagnosis of pulmonary embolism.

The purpose of this study, performed in patients with suspected pulmonary embolism (PE), was to compare V/Q scans and electron beam computed tomography (CT) scans on a patient-by-patient and segment-by-segment basis. Both a segment-based and a lobe-based analysis was performed in those patients positive for PE. The diagnosis of PE was assumed on the basis of a mismatch at V/Q scanning or a filling defect in a pulmonary vessel at contrast-enhanced electron beam CT.
