Evaluation of activity kinetics in breast milk and calculation of the resulting effective radiation dose after 99mTc-MIBI scintigraphy of a breastfeeding women

Introduction In breastfeeding women, the indication for scintigraphic imaging is strongly restricted due to potential transition of the radiopharmaceutical to the child via breast milk. The potential activity uptake of the breastfed child depends on the chemical compound of the radio pharmaceutical as well as biokinetics and metabolism in the maternal body.

Methods In the presented case <sup>99m</sup>Tc-MIBI scintigraphy was performed in a breastfeeding woman with sonographically suspicious thyroid...

Comparison of bone marrow biopsy and fluorodeoxyglucose-positron emission tomography for the assessment of bone marrow infiltration in children with Hodgkin’s lymphoma

Purpose To compare bone marrow biopsy (BMB) with [18F]-fluoro-2-deoxy-d-glucose positron emission tomography/computed tomography (PET/CT) imaging in the demonstration of bone marrow involvement in children with Hodgkin’s Lymphoma (HL) and to investigate the effectiveness of PET/CT imaging and thus the necessity for BMB at staging.

Methods Pediatric patients with HL, who underwent both bilateral iliac BMB and PET/CT imaging at disease staging were retrospectively analyzed. In determining bone marrow...

Diagnostic value of FDG-PET/CT in the diagnostic work-up of inflammation of unknown origin

Introduction The present study aims to evaluate the clinical diagnostic value of FDG-PET/CT in patients with inflammation of unknown origin. Material and methods We retrospectively analyzed data of 130 patients who presented general inflammatory symptoms and/or elevated level of CRP and underwent FDG-PET/CT for the purpose of identifying unknown foci of inflammation. The accuracy of PET/CT findings was assessed against the standard of eventual clinical diagnosis e.g. results of pathology, microb...

Adverse events unlikely after fine-needle aspiration biopsies of thyroid nodules in patients on low-dose aspirin: a prospective controlled systematic single center analysis

Aim Our aim was to test the assertion that in terms of rate or severity level, adverse events (AEs) after fine-needle aspiration biopsies (FNABs) of thyroid nodules are unfazed by daily low-dose (100 mg) aspirin (acetylsalicylic acid, ASA) intake.

Methods We selected 268 patients for study, grouped as ASA-treated (PASA, n=78) or control (PCtrl, n=190) subjects. Controls received no antithrombotic medication. AE rates and severities were then analyzed based on patient- and nodule-related factors. We...
