Gallium-68-labeled prostate-specific membrane antigen ligands are not only established radiopharmaceuticals for staging of prostate cancer but also accumulate physiologically in nonprostate organs, including the salivary glands. We show the converted application of prostate-specific membrane antigen -positron emission tomography/computed tomography (PSMA-PET/CT) as a dedicated method to depict salivary gland tissue using a region-focused, low-dose protocol. An accessory parotid gland at the righ...

Aus fachfremder Sicht wird der Stellenwert der „konventionellen“ Schilddrusenszintigrafie zur Klarung diverser thyreologischer Fragestellungen international mittlerweile weit niedriger eingeschatzt, als dies dem hierzulande tatigen Nuklearmediziner bewusst ist. Dieser Aufsatz gibt einen Uberblick uber haufig geauserte Kritikpunkte an der Schilddrusenszintigrafie und mochte einiges hierzu klarstellen sowie in berechtigten Fallen fundierte Gegenargumente liefern. In diesem Rahmen wird ein Uberblic...

Abstract Purpose To evaluate the microsphere flow dynamics and residual yttrium-90 (90Y) activity during and after transarterial radioembolization with glass microspheres and to assess the distribution and predilection sites of residual activity in the administration devices. Materials and Methods In this laboratory investigation, after 18 consecutive clinical transarterial radioembolization and 4 ex vivo experimental procedures with 90Y glass microspheres, the distribution of residual activity ...

In conventional thyroid diagnostics, the topographical correlation between thyroid nodules (TN) depicted on ultrasound (US) in axial or sagittal orientation and coronally displayed scintigraphy images can be challenging. Sensor-navigated I-124-PET/US fusion imaging has been introduced as a problem-solving tool for ambiguous cases. The purpose of this study was to investigate the results of multiple unexperienced medical students (MS) versus multiple nuclear medicine physicians (MD) regarding the...

52 Background: Conventional diagnostics (CD) of thyroid nodules (TN) comprises ultrasound (US) and scintigraphy scans. Combining these two modalities can lead to uncertain or incorrect topographic assignments. Hybrid imaging is an established and successful solution for many issues in nuclear medicine. However, research data on SPECT/US and PET/US fusion imaging of the thyroid are scarce. The present data firstly represent the value of fusion imaging in the field of TN diagnostics on the basis o...

BACKGROUND: Primary hyperparathyroidism is a rare condition of disease which can seldomly present as giant retrotrhyroideal cysts, complicating the localization of the adenoma to resect. CASE PRESENTATION: A 56-year old female presented with hypercalcaemia of 3.38 mmol/L (2.2-2.65 mmol/L) and a history of breast cancer. A fast growing cystic parathyroidal adenoma was diagnosed by a multimodal approach including comprehensive diagnostic imaging (ultrasonography, scintigraphies, dynamic MRI) and c...
