In 100 children with suspected left to right shunts the ratio of pulmonary to systemic flow was measured both by oximetry and first pass radionuclide angiography. The pulmonary time activity curve from the radionuclide study was analysed by the method of gamma variate fits. There was strong correlation between the two techniques; weaker correlation was found when the shunt was at atrial rather ...

The aim of this overview article is to present the current possibilities of radionuclide scintigraphic small intestine imaging. Nuclear medicine has a few methods-scintigraphy with red blood cells labelled by means of (99m)Tc for detection of the source of bleeding in the small intestine, Meckel's diverticulum scintigraphy for detection of the ectopic gastric mucosa, radionuclide somatostatin r...

Introduction Over the last 5 decades, radionuclide generators have attracted substantial attention, indeed close scrutiny of the nuclear medicine community owing to their ability to provide short-lived radioisotopes without the need for on-site nuclear reactor or cyclotron facilities for preparation of a wide variety of diagnostic and therapeutic radiopharmaceuticals [1]. The radionuclide gener...

177Lu has sprung as a promising radionuclide for targeted therapy. The low soft tissue penetration of its β- emission results in very efficient energy deposition in small-size tumours. Because of this, 177Lu is used in the treatment of neuroendocrine tumours and is also clinically approved for prostate cancer therapy. In this work, we report a separation method that achieves the challenging sep...

The American College of Radiology has developed appropriateness criteria for a number of clinical conditions and procedures. Criteria are available on imaging tests used in the evaluation of acute chest pain--suspected myocardial ischemia. Imaging tests for a suspected cardiac etiology include transthoracic echocardiography, transesophageal echocardiography, radionuclide perfusion imaging, radi...
