Rationale: Radiation dose to patients from imaging modalities are measured or calculated to assess the risk of the procedure and compared it to the benefits. Periodic review of image acquisition methods and radiation dose used are essential part of procedure optimization in medical imaging. The aim of this study was to estimate patient radiation do...

Yttrium-90 radioembolization is a safe and efficacious treatment option for many patients with unresectable hepatocellular carcinoma. Potential candidates for radioembolization, based on clinical criteria, undergo technetium-99m labeled macroaggregated albumin imaging to determine the extent of hepatopulmonary shunting. Dose selection is based on r...

The phenomena of adsorption of several 99mTc-radiopharmaceuticals on disposable syringes is common knowledge and can reach a level of up to 50%, with the result of inadequate dosage. The resulting underdosage has a substantial influence on the quality of imaging, especially in pediatric patients. Therefore, we aimed to establish a standardized in-v...

The skeleton is overall the third most common metastatic site after the lungs and liver. Accurate diagnosis of osseous metastasis is critical for initial staging, treatment planning, restaging, treatment monitoring and survival prediction. Currently, 99mTc-methylene diphosphonate (99mTc-MDP) whole-body scan is the cornerstone of imaging to detect o...

Positron emission tomography (PET) imaging, particularly oncologic applications of fluorine-18 fluorodeoxyglucose (18F-FDG), has become a routine diagnostic study. To better describe the malignancies, various PET parameters are used. In 18F-FDG PET studies, maximum standardized uptake value (SUVmax) is the most commonly used parameter to provide a ...

We present a 72-year-old female with an osseous metastasis to the spine, which had an atypical appearance on both nuclear medicine and radiological modalities and was misdiagnosed as an abscess. We discuss the pitfalls of bone scintigraphy and the causes of photopenic metastatic lesions. Copyright © 2019 by the Society of Nuclear Medicine and Molec...

An adult lymphoma patient developed Cushing's syndrome following short-term, high-dose dexamethasone administration and presented with distinctive Cushingoid fat redistribution pattern and associated white adipose tissue increased 18F-FDG uptake. Recognition of the unique 18F-FDG uptake manifestation may aid in the diagnosis of this iatrogenic synd...

Introduction: Gastroparesis is a debilitating disease of insufficient gastric emptying and visceral hypersensitivity characterized by nausea, vomiting, early satiety and bloating. Gastric emptying scintigraphy (GES), in combination with typical symptoms and normal esophagogastroduodenoscopy, is used to diagnose the disease. Gastric per-oral endosco...

Sister Mary Joseph nodule is an umbilical metastatic lesion typically originating from gastrointestinal or gynecologic malignancies. In pancreatic cancer, Sister Mary Joseph nodule is a sign of advanced disease with an associated poor prognosis. 18F-FDG PET/MRI provides an imaging tool in the identification of Sister Mary Joseph nodule and helps to...
