The diagnosis of haemangiomata and cutaneous vascular malformations is based on clinical history and physical exploration. Imaging studies might be necessary to clarify and confirm the diagnosis, and in order to analyse the extent of the lesions by permitting an evaluation of their non-visible component as well as the affection of neighbouring structures. Finally, they also play an important ro...

There were 50 patients under observation. Symptoms and signs were assessed and their significance in the establishing of congenital vascular malformation diagnosis was evaluated. The following imaging procedures were made: ultrasound duplex scan in 29, arteriography in 15, phlebography in 19, MRA in 3, CTA in 4 patients, lymphography in 1 patient. Surgical treatment consisted of phlebectomy, li...

Radiometals are the mainstay of both diagnostic and therapeutic nuclear medicine because the choice of radionuclide is primarily dictated by nuclear decay characteristics rather than chemistry. (99m)Tc is the most frequently used diagnostic radionuclide and requires coordination in a diversity of chemical disguises to permit imaging of a variety of tissues and disease states. Therapeutic nuclea...

Problem statement: Forest fires are especially frequent around the Mediterranean Sea basin in the summer period and might be able to release naturally-occurring and man-made radionuclides from plant biomass and inject them into the atmosphere. The impact of this radioactivity on populations was not investigated before. Approach: Radionuclide analysis was performed in plants, in smoke from plant...

Background: In internal radiation therapy of cancer, optimal targeting ligand and type therapeutic radionuclide must be considered carefully for effective treatment. addition, nuclide may vary depending on diverse parameters characterizing the tumor. Thus, use in various cancers, there is a need development carrier that can firmly bind to variety nuclides. Here we introduce biocompatible iron o...

The present study examines the extent of spinal cerebrospinal fluid (CSF) absorption in healthy individuals in relation to physical activity, CSF production, intracranial pressure (ICP), and spinal CSF movement. Thirty-four healthy individuals aged 21-35 yr were examined by lumbar puncture and radionuclide cisternography with repeated imaging. ICP was registered before and after CSF drainage, a...

The saphenous venous system was visualized by CT without any contrast medium injection. Volumetric data were acquired with a multidetector spiral CT (Siemens, Somatom Plus 4 Volume Zoom) with the following parameters: collimation, 1 mm; pitch, 4; reconstruction, 1.2 mm. Reformatted images were then transferred in DICOM format to an 02 work station (Silicon Graphics) and postprocessed by the sof...

The detection of regional asynergy provides strong evidence for a critical reduction of coronary blood flow to that zone. In the present study, the usefulness of combining computer-assisted radionuclide angiography and isometric handgrip exercise testing to detect coronary heart disease (CHD) was evaluated. One hundred twenty-nine patients with chest pain undergoing cardiac catheterization were...
