OBJECTIVES: Gadolinium (Gd) is toxic and to avoid its deposition in the tissues, it must be chemically bonded with nonmetal ions to facilitate its excretion by the kidneys. High signal intensity in the dentate nucleus (DN) and globus pallidus (GP) on unenhanced T1-weighted MR images has been both morphologically and pathologically linked to gadolinium-based contrast agent (GBCA) retention in the brain. The purpose of this study is to determine if repeated administrations of GBCA would affect the uptake of (18)F-FDG in the DN and GP on PET/CT...

We present a case study of a 56-y-old man who was admitted with acute abdominal pain and was found to have retroperitoneal hematoma from a ruptured duodenal aneurysm. (99m)Tc-diisopropyliminodiacetic acid cholescintigraphy showed incidental absent transit of radiotracer into the distal duodenum and severe enterogastric reflux, thought to be secondary to duodenal obstruction from the hematoma. Findings were confirmed on esophagogastroduodenoscopy, and the patient improved after subsequent gastrojejunostomy.

: The Society of Nuclear Medicine and Molecular Imaging and European Association of Nuclear Medicine procedure guide on gastrointestinal transit currently indicates that the mean of total abdominal counts of 7 time points (0-360 min) is used to define the total abdominal counts for bowel transit studies. The purpose of this study was to investigate the variability of total abdominal counts during the initial 6 h of bowel transit and to determine whether a simplified, single-time-point measurement can be used...

We herein report an unusual case of a 55-y-old woman with papillary carcinoma of the thyroid, who presented with multiple recurrences, with its subsequent evolution to tall cell variant and thyroglobulin-elevated negative iodine scintigraphy (TENIS) syndrome. During the course of the disease the lesions became non-iodine-concentrating with an increased proportion of tall cells and evidence of local and distant metastasis. Molecular analysis of the tissue specimen demonstrated BRAF(V600E) and I582 M mutations along with upregulation of tumor markers in metastatic tissue...

Kelly D Archer, Norman E Bolus
: Throughout the years, the role of nuclear medicine departments in the care of renal patients has changed as a result of technologic advancements and other factors. This study evaluated the current role of nuclear renal imaging. METHODS: A survey was generated with questions about patient populations, the clinical indications most often seen, radiopharmaceutical use, measurement techniques, the average number of scans completed, and medical center/transplant team affiliations...

REVIEW
Rohit Kedia, Neil Hansen, Whitney Goldner
Paragangliomas associated with mutations of the SDHD gene can occasionally result in distant metastasis. Diagnosis can be difficult, and nuclear imaging is used to evaluate the case further. Not all tumors are alike; nuclear avidity may differ. We present a case in which metastatic paraganglioma caused by mutations of the SDHD gene was negative on (123)I-metaiodobenzylguanidine scintigraphy and positive on (111)In-labeled octreotide scintigraphy. This situation presents an opportunity for a novel therapeutic approach toward metastatic paraganglioma using targeted peptide receptor radionuclide therapy...

: The human epidermal growth factor 2 (HER2)-overexpressing (HER2-positive [HER2+]) gastric (GC) and gastroesophageal junction adenocarcinomas (GEJC) are felt to represent a more aggressive form of disease, which may correlate to increased metabolic activity. Whether tumor SUVmax measured by (18)F-FDG PET/CT could be a preoperative parameter used to predict HER2 status of GC/GEJC is unknown. METHODS: Pathology reports of HER2+ GC/GEJC biopsies and resections from 31 patients were reviewed and compared with HER2-negative (HER2-) cases distributed evenly over the same time period...

: The purpose of this research was to evaluate the need to use heparin when preparing an UltraTag red blood cell (RBC) kit for a nuclear medicine study. METHODS: Nonheparinized blood samples (n = 15) and heparinized blood samples (n = 15) were added to UltraTag RBC kits. The samples were examined for macroscopic blood clotting and microscopic platelet clumping. As a control, samples with heparin (n = 15) and without heparin (n = 15) were used to help evaluate the effectiveness of the anticoagulant properties within the UltraTag RBC kit (sodium citrate) and whether those properties played a role in preventing clots or clumps...

REVIEW
Sandip Basu, Preeti Fargose
The potential of peptide receptor radionuclide therapy (PRRT) is described in a case of recurrent inoperable phosphaturic mesenchymal tumor causing osteomalacia in the left basiocciput, for which the patient had undergone surgery twice previously. After one cycle of PRRT, there was good symptomatic improvement, with a modest reduction in uptake on both (68)Ga-DOTATATE PET/CT and (18)F-FDG PET/CT suggesting a favorable response. Hence, treatment with a second cycle was considered. Being somatostatin receptor-avid, this rare group of tumors when inoperable or recurrent may potentially be targeted with PRRT...

We describe the role of (18)F-sodium fluoride ((18)F-NaF) PET/CT bone scanning in the staging of breast and prostate cancer. (18)F-NaF PET was initially utilized as a bone scanning agent in the 1960s and early 1970s, however, its use was restricted by the then-available γ-cameras. The advent of hybrid PET/CT cameras in the late 1990s has shown a resurgence of interest in its use and role. After a brief introduction, this paper describes the radiopharmaceutical properties, dosimetry, pharmacokinetics, and mechanism of uptake of (18)F-NaF...

: This study was designed to evaluate the effectiveness of video goggles in distracting children undergoing PET/CT and to determine whether the goggles create CT and PET artifacts. METHODS: Video goggles with small amounts of internal radioopaque material were used. During whole-body PET/CT imaging, 30 nonsedated patients aged 4-13 y watched videos of their choice using the goggles. Fifteen of the PET/CT studies were performed on a scanner installed in 2006, and the other 15 were performed on a scanner installed in 2013...

: When a radiation incident occurs in nuclear medicine in Australia, the incident is reported to the relevant state or territory authority, which performs an investigation and sends its findings to the Australian Radiation Protection and Nuclear Safety Agency. The agency then includes these data in its Australian Radiation Incident Register and makes them available to the public as an annual summary report on its website. The aim of this study was to analyze the radiation incidents included in these annual reports and in the publically available state and territory registers, identify any recurring themes, and make recommendations to minimize future incidents...

Paul D Rodrigue, Asif A Fakhri, Jin T Lim
After significant trauma to the spleen, small viable splenic fragments may exist in the peritoneal cavity or, less commonly, in the thorax. Thus, the appearance of splenules within the thorax on CT images can easily be mistaken for malignancy and lead to unnecessary intervention. Here, we present a case of multiple pulmonary masses that initially were presumed to be malignancy, leading to CT-guided biopsy, but were eventually confirmed to be thoracic splenules through (99m)Tc-labeled sulfur colloid scintigraphy...

Primary gastric lymphoma (PGL) accounts for less than 4% of gastric neoplasms. (18)F-FDG PET with simultaneously acquired CT ((18)F-FDG PET/CT) allows for staging and differentiation from other gastric cancers. Rapid diagnosis and staging are important because chemotherapeutic response is generally favorable. We describe a case of an 83-y-old woman with stage II1 PGL. (18)F-FDG PET/CT can be helpful to differentiate various gastric masses and is an important factor in the staging of PGL.

There are multiple reasons for an anterior mediastinal mass. In this case, we discuss possible etiologies and offer an algorithm to narrow the differential diagnosis. When the mass cannot be diagnosed radiographically, the next step in imaging is a physiologic assessment with radionuclide modalities.
