The role of 18F-Fluorodeoxyglucose Positron Emission Tomography in patients with suspected recurrence or metastatic differentiated thyroid carcinoma with elevated serum thyroglobulin and negative I-131 whole body scan.
The aim of this study is to evaluate the role of ¹⁸F-FDG PET/CT in the detection of recurrence or distant metastasis in patients with differentiated thyroid carcinoma (DTC) with elevated serum thyroglobulin (Tg) and negative ¹³¹I whole-body scan. ⋯ 1. ¹⁸F-FDG PET/CT is useful in the diagnosis of radioiodine-negative DTC in patients with high levels of stimulated Tg. 2. The sensitivity of ¹⁸F-FDG PET/CT increases with stimulated Tg levels. At stimulated Tg > 28.5 ng/ml, the sensitivity of the study reaches 100%.

Comparative Study Clinical TrialComparison between 99mTc-sestamibi gated myocardial perfusion SPECT and echocardiography in assessment of left ventricular volumes and ejection fraction--effect of perfusion defect and small heart.
Agreement between gated myocardial perfusion SPECT (GSPECT) and echocardiography (ECHO) in the calculation of left ventricular end-diastolic volume (EDV), end-systolic volume (ESV) and LVEF was assessed. Effect of perfusion defect and small hearts on this agreement was obtained. Because ECHO is a routine and widely used noninvasive modality for this purpose, we chose this technique for comparison with GSPECT. ⋯ There was a good agreement between EDV, ESV and LVEF derived from GSPECT and ECHO. There was a significant difference between two modalities in small hearts and in patients without perfusion defect, although in larger ventricles or in the presence of myocardial infarction no remarkable difference between two modalities was noticed.

Case ReportsComplex Regional Pain Syndrome type I with atypical scintigraphic pattern--diagnosis and evaluation of the entity with three phase bone scintigraphy. A case report.
Complex Regional Pain Syndrome (CRPS) is a neurological disorder of unknown etiology which may lead to severe disability. Its diagnosis is very difficult and based on diagnostic criteria which have been changing over last years. Still, there is no golden standard in diagnosis of this entity. ⋯ Different diagnostic modalities can also be helpful when CRPS is suspected including plain film radiography, magnetic resonance imaging and ultrasonography. Multidisciplinary approach is necessary for proper and quick diagnosis. We present a case of CRPS in 12-year-old girl in whom the diagnosis was based on the bone scan.
