Background Early phase amyloid positron emission tomography (PET) imaging is known to correlated with glucose metabolism. However, studies on the optimal time frame and SUVR cut off for early-phase PET have not been sufficiently progressed. In this study, of 18F-FBB was determined obtained. Method To determine frame, correlation between FBB FDG 67 subjects(34, Alzheimer’s disease(AD), 4 mild co...

OBJECTIVE To assess the clinical value of dual tracers Positron emission tomography/computed tomography (PET/CT) (18)F-fluoroestradiol ((18)F-FES) and (18)F-fluorodeoxyglucose ((18)F-FDG) in predicting neoadjuvant chemotherapy response (NAC) of breast cancer. METHODS Eighteen consecutive patients with newly diagnosed, non-inflammatory, stage II and III breast cancer undergoing NAC were includ...

A 60-year-old patient with testicular seminoma was referred for F-18 FDG PET/CT Study to evaluate recurrence. In addition to hypermetabolic cervical, mediastinal and hilar lymph node tumoral metastases, segmental intense FDG uptake along the lumbar spinal cord suggestive of tumoral metastasis was noted which quite an unusual presentation is.  At the time of PET study the patient was symptomless...

PURPOSE To evaluate the appropriate post-injection timing for hand-held-gamma-ray-detecting probe (GDP) scanning for the intraoperative detection of malignancy after preoperative F-18 FDG (FDG) injection. METHODS Patient study with superficially located cancer was performed on three patients before operation by dual-phase whole-body PET at 2 and 6-7 hr post-injection of FDG (370 MBq), and by ...

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 ...

This report describes a case of extensive diffuse bone marrow involvement with bilateral breast metastases from duodenal neuroendocrine tumor giving rise to a superscan-like appearance on somatostatin receptor-targeted (99m)Tc-hydrazinonicotinamide-TOC scintigraphy. The metastatic lesions demonstrated partial concordance with (18)F-FDG PET/CT findings, signifying varying tumor biology and heter...

PURPOSE To retrospectively evaluate the utility of positron emission tomography-computed tomography (PETCT) in the diagnosis of percutaneous endoscopic gastroscopy (PEG) site metastases in head and neck cancer. MATERIALS AND METHODS From the database of 250 patients of head and neck cancer who were referred for PET-CT over 2 years (from January 2005 to January 2007), 6 patients who had PEG tu...
