The beginning of neuroradiology can be traced to the early 1900s with the use of skull radiographs. Ventriculography and pneumoencephalography were introduced in 1918 and 1919, respectively, and carotid angiography, in 1927. Technical advances were made in these procedures during the next 40 years that lead to improved diagnosis of intracranial pathology. Yet, they remained invasive procedures ...

Cardiac nuclear medicine refers to three techniques: 1. Radionuclide ventriculography (RNV, also known as MUGA) 2. Myocardial perfusion scintigraphy (MPS) 3. Positron emission tomography (PET) Radionuclide ventriculography has been largely superseded by echocardiography. Occasionally it is helpful in determining ventricular function when echocardiographic views are limited and there is a contra...

Twenty five patients who had undergone conventional coronary arteriography and left ventriculography for suspected coronary artery disease had left ventriculography performed by digital subtraction angiography as outpatients; there were no complications requiring admission to hospital. A catheter was introduced percutaneously and positioned in the superior vena cava; 40-50 ml of contrast medium...

OBJECTIVE To study the effects of metoprolol tartrate therapy in patients with heart failure. METHODS Fifty patients (36 males) aged 52+/-14.8 yrs, with functional class II to IV heart failure (HF) and left ventricular ejection fraction (LVFE) < 45%, assessed by radionuclide ventriculography, were evaluated in a retrospective study. Metoprolol tartrate was added to the usual therapy, with a s...
