The diagnosis of brain death is a clinical diagnosis that is sometimes made with the help of cerebral perfusion scintigraphy. It is important that all physicians be knowledgeable about the clinical requirements for the diagnosis of brain death, especially the need to establish irreversible cessation of all function of the cerebrum and brain stem. Institutions performing scintigraphy for the eva...

OBJECTIVE: To give a comprehensive overview of fetal doses reported in the literature when imaging the pregnant woman with suspected pulmonary embolism (PE). METHODS: A comprehensive literature search in the PubMed, MEDLINE and EMBASE databases yielded a total of 1,687 papers that were included in the analysis and have been analysed with regard to fetal dose in suspected PE radiological imagin...

A 43-year-old woman experienced increasing dyspnea over a period of 1 year. She was examined first at an outside hospital. Diagnostic workup revealed an elevated precapillary mean pulmonary arterial pressure of >44 mm Hg. Left ventricular function was nearly normal (cardiac index, 2.1 L/min·m; pulmonary wedge pressure, 15 mm Hg). Computed tomography of the lung demonstrated regional ground glas...

Nuclear medicine is a diverse medical field, encompassing a wide range of studies. Many studies are performed on a daily basis, whereas some nuclear medicine studies are performed on a more infrequent basis. The following article is the second article in a 2-part series on infrequently performed studies in nuclear medicine. The procedures reviewed include CSF shunt imaging, brain death scintigr...

PURPOSE To study the bronchial and vascular anastomosis in the autologous lobar lung implant and show if exist complications in transplants occupying only half of pleural cavity. METHODS We studied 15 male from 8 to 14 kg. After pneumonectomy in the left chest wall we replaced the caudal lobe. In the late post operative we made bronchography and perfusion's scintigraphy and analysed the lungs...

BACKGROUND Due to the different properties of the contrast agents, the lung perfusion maps as measured by 99mTc-labeled macroaggregated albumin perfusion scintigraphy (PS) are not uncommonly discrepant from those measured by dynamic contrast-enhanced MRI (DCE-MRI) using indicator-dilution analysis in complex pulmonary circulation. Since PS offers the pre-capillary perfusion of the first-pass tr...
