The aim was to assess the requirements for a positron emission tomography (PET) cancer imaging service. The UK was used as an example to create a mathematical model for calculating the number of dedicated PET scanners and cyclotron/radiochemistry production facilities required to support the demand for PET studies in lung cancer. This was then extended to all oncological indications for PET and comparison was made with present infrastructure in the UK and Europe.

Methods And Patients: We present various patterns of PM observed on myocardial PET imaging in 4 patients.
Purpose Of Review: Radionuclide renography has become standard practice but with controversial areas and variations in technique. This review looks at some recent studies to improve usefulness and to assess the current clinical indications for the use of dynamic radionuclide renography and considers some of the recent publications that have contributed to the subject during the past year.
Recent Findings: Two important papers attempting to standardize the diuretic renogram and provide normal values for the MAG3 renogram are reviewed together with exercise renography in hypertension and used for the Captopril test.
Background: Revascularization of patients with ischemic heart disease and poor left ventricular function for surgical procedures is expensive and carries considerable risks, but may improve survival for patients with hibernating myocardium. Positron emission tomography can detect hibernating myocardium, and may be cost-effective if used to select patients for operation.
Methods: An economic model was developed to compare the cost-effectiveness of three management strategies: (1) coronary artery bypass grafting for all patients; (2) using positron emission tomography to select candidates for coronary artery bypass grafting, those without hibernation remaining on medical therapy; and (3) medical therapy for all patients.
