Optimal scan time for evaluation of parathyroid adenoma with [18F]-fluorocholine PET/CT
BACKGROUND Parathyroid adenomas, the most common cause of primary hyperparathyroidism, are benign tumours which autonomously produce and secrete parathyroid hormone. [(18)F]-fluorocholine (FCH), PET marker of cellular proliferation, was recently demonstrated to accumulate in lesions representing enlarged parathyroid tissue; however, the optimal time to perform FCH PET/CT after FCH administratio...
متن کاملDual-time-point myocardial 18F-FDG imaging in the detection of coronary artery disease
BACKGROUND Myocardial 18F-deoxyglucose (18F-FDG) uptake has been observed to be enhanced in patients with coronary artery disease (CAD) under fasting conditions. However, whether the increased 18F-FDG is induced by myocardial ischemia and how to discriminate ischemic from physiological 18F-FDG uptake have rarely been investigated. METHODS Under fasting conditions, 18F-FDG PET imaging was perf...
متن کاملDual-Time Point Whole-Body 18F-Fluorodeoxyglucose PET/CT Imaging in Undiagnosed Mediastinal Lymphadenopathy
Sarcoidosis and TB, the two most common benign causes of mediastinal lymphadenopathy, share remarkable clinical, radiologic, and histologic similarities. 1 Diff erentiation between the two remains a diffi cult task for pulmonary physicians, particularly in countries with a high burden of TB. 2 We performed a dual-time point 18 F-fl uorodeoxyglucose (FDG) PET/CT scan in 117 consecutive patients ...
متن کاملVisualization of Parathyroid Hyperplasia Using 18F-Fluorocholine PET/MR in a Patient With Secondary Hyperparathyroidism.
Several imaging modalities exist for the detection of parathyroid adenomas in patients with primary hyperparathyroidism. Unlike solitary parathyroid adenoma, parathyroid hyperplasia in patients with secondary hyperparathyroidism hitherto is difficult to assess with any imaging modality. Our case of a young patient with chronic kidney failure illustrates that F-fluorocholine PET/MR might be an i...
متن کاملDual-time-point FDG-PET/CT Imaging of Temporal Bone Chondroblastoma: A Report of Two Cases
Temporal bone chondroblastoma is an extremely rare benign bone tumor. We encountered two cases showing similar imaging findings on computed tomography (CT), magnetic resonance imaging (MRI), and dual-time-point 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT. In both cases, CT images revealed temporal bone defects and sclerotic changes around the tumor. Most parts of the ...
