One of the most important roles of cardiovascular nuclear medicine in evaluating patients with coronary artery disease (CAD) is predicting patient outcome. Measurements of ventricular function obtained by radionuclide ventriculography play a key role in defining a patient's prognosis. Because ventricular function correlates well with the total extent of myocardial ischemic burden, data derived ...

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...

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...

Introduction: This Study has was  carried out to measure and detect the natural occurred radionuclide content including 226Ra, 232Th and 40K in the  Nile River sediments at various locations in Upper Egypt, from Aswan to El-Minya. Additionally, we determine the absorbed dose rate, the annual effective dose equivalent, and excess lifetime cancer risk also has been calculated. Material and Metho...

Background: Owing to its favourable decay characteristics 177Lu [T1/2= 6.71 d, Eβ(max)= 497 keV] is an attractive radionuclide for various therapeutic applications. Ethylene diamine tatramethylene phosphonate (EDTMP) is one of the most widely used ligands which form stable complexes with various radionuclides and all the complexes. Materials and Methods: Enriched 176Lu2O3 was dissolve...

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 (PRRT) has been applied to the treatment of neuroendocrine tumors (NETs) for over two decades. However, improvement is still needed, and targeted alpha (TAT) with emitters such as lead-212 (212Pb) represents a promising avenue. A series ligands based on octreotate was developed. Lead-203 used an imaging surrogate selection best candidate studies lead-212. 2...

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 ...
