Single photon emission tomography (SPET) employing 99Tcm-sestamibi (MIBI) injected intravenously was performed in 27 patients for pre-surgical evaluation of intraparenchymal brain tumours. A computerized tomography (CT) scan was performed in 26 patients, magnetic resonance imaging (MRI) in 8 patients and digital subtraction angiography (DSA) in 14 patients.(More)
The purpose of optimising the acquisition parameters in positron emission tomography is to improve the quality of the diagnostic images. Optimisation can be done by maximising the noise equivalent count rate (NECR) that in turn depends on the coincidence rate. For each bed position the scanner records coincidences and singles rates. For each patient, the(More)
he introduction of computed tomography (CT) has greatly improved lymphoma staging procedures and is presently the most common and most important radiologic technique employed for this purpose and for evaluating the response to treatment. However, since CT only gives an anatomic measure of the tumor, in some cases (particularly those with bulky mediastinal(More)
Five tumor markers (CEA, Ferritin, CA-50, TPA and SCC) were assayed in 54 patients with ear, nose and throat (ENT) cancers in early and advanced stages. The specificity of these markers always exceeded 95%. Their sensitivity ranged from 13 to 43%, and reached 72% as a combination of all five markers. No distinction was found between early and advanced stage(More)
BACKGROUND The use of point-of-care ultrasonography (POC US) in paediatrics is increasing. This study investigated the diagnostic accuracy of POC US in children accessing the emergency department (ED) when performed by paediatricians under the remote guidance of radiologists (TELE POC). METHODS Children aged 0 to 18 years accessing the ED of a third level(More)
INTRODUCTION An acute abdomen in the form of small-bowel volvulus could be a presentation of a lymphatic malformation in childhood. CASE PRESENTATION A 5year old male was admitted to our Institute for an acute abdomen. Clinical aspects and radiological images were not specific for a certain diagnosis. Laparotomy revealed a big soft mass, with a milky(More)
Visualization of cerebral perfusion with Single Photon Emission Computed Tomography (SPET) needs lipophil radiotracers which are able to cross the intact blood-brain-barrier (BBB); moreover local uptake must reflect regional cerebral blood flow. In the last decade many radiopharmaceuticals have been suggested and employed for this purpose. Recently a new(More)
