OBJECTIVE To compare the diagnostic performance of a new dedicated ultrafast solid-state cardiac camera (Discovery NM 530c [DNM]) with standard dual detector cameras (S-SPECT) in myocardial perfusion imaging. The primary goal was a per-patient analysis of diagnostic performance of the DNM using S-SPECT as the reference standard. METHODS AND RESULTS In(More)
UNLABELLED Fever of unknown origin (FUO) is a challenging diagnostic problem. Timely identification and precise localization of the causing process are critical for appropriate patient management. The present prospective study evaluates the role of PET/CT using (18)F-FDG in the investigation of FUO. METHODS A total of 48 consecutive patients (25 men, 23(More)
Epithelioid hemangioendothelioma is a rare vascular tumor of borderline or low-grade malignancy. The lungs and liver are the two common primary organs affected. Metastatic disease was reported in more than 100 cases in the literature. However, no firm conclusions can be determined for recommended treatment options. The current case presents a patient with(More)
Gelastic seizures comprise a very rare form of epilepsy. They present with recurrent bursts of laughter voices without mirth and are most commonly associated with the evolution of a hypothalamic hamartoma. The purpose of this article is to describe the second reported ictal fluorodeoxyglucose-positron emission tomography study in a unique case of an infant(More)
was 40°C, blood pressure 90/60 mmHg and heart rate 110 beats per minute. Neck rigidity and diffuse abdominal tenderness were noted, together with mild hepato-splenomegaly. Laboratory tests revealed leukopenia of 2200 cells/µl with a left shift and 87% neutrophils. The hemoglo-bin was 12.9 g/dl and mean corpuscular volume 77 fl. Erythrocyte sedimentation(More)
Preserved blood flow to bone and soft tissue is essential for their normal function. To date only numerous methods are suitable for direct bone blood flow (BBF) measurement. Here, we introduce a novel quantitative method for bone and soft tissue blood flow (BBF and SBF, respectively) measurement. It involves a combination of SPECT/CT imaging for blood pool(More)
Fluorodeoxyglucose positron emission tomog-raphy/computed tomography (FDG PET/CT) is used in the imaging workup of various malignancies. Incidental gastro-intestinal observations on FDG PET/CT may be of clinical significance. The aim of the present study was to evaluate endoscopic and histopathological observations in patients referred for colonoscopy due(More)
