Radionuclide cisternography is generally considered to be a safe procedure without significant neurological complications. However, in this report we present a patient who developed conus medullaris syndrome following radionuclide cisternography. A 46-year-old woman underwent lumbar puncture followed by radionuclide cisternography with the diagnosis of hydrocephalus. After the cisternography, s...

Materials developed for radionuclide adsorption need to resist harsh conditions, i.e. be robust against ionizing radiation. In this work, we evaluated the degradation of mesoporous silicas (SBA-15) grafted with hydroxypiridinone, acetamide phosphonate and propionamide ligands under electron irradiation. The contained amide and/or phosphinic acid functional groups, which made them able bind acti...

The images are acquired ...

This is the second of two pictorial essays on radionuclide imaging of the lymphatic system and will focus on evaluation of extremity lymphoedema using lymphoscintigraphy. Lymphoedema results from anatomical or functional obstruction of the lymphatic system. Lymphoscintigraphy is the imaging modality of choice for assessing lymphoedema. The technique plays a pivotal role in determining the aetio...

Limitations of Radionuclide Flow Studies in Bilateral Carotid Thrombosis • Radionuclide angiography as a noninvasive procedure has become an important tool in the evaluation of cerebrovascular diseases. Determinations of arm-to-brain circulation times complemented by the transit times of the radionuclide bolus through the brain afford insight into the functional status of the vascular system of...

Peptide receptor radionuclide therapy is a type of molecular radiotherapy that has been used in the treatment patients with neuroendocrine tumours for over two decades. It not until recently, however, it achieved regulatory approval. The currently approved regimen one-size-fits-all scheme, i.e. all receive fixed activity radiopharmaceutical (177Lu-DOTATATE) and number cycles. Several research g...

A simple, noninvasive method for measurement of right-to-left intracardiac shunts would enhance the management of patients with congenital heart disease. This study describes application of data processing techniques used previously in dye-indicator curves to data recorded during the initial transit of radioactive bolus through the central circulation. Radionuclide angiocardiograms were perform...

A consecutive series of 56 patients with chest pain but no evidence of previous myocardial infarction was prospectively studied by radionuclide ventriculography to determine the value of global and regional radionuclide indices in detecting coronary artery disease. The results were correlated with the clinical judgment of chest pain, the results of the exercise electrocardiogram, and the right ...
