During the last two decades significant advances have been made in the in vivo-diagnosis of gastrointestinal diseases. Although Ultrasound and CT as well as Endoscopy have had a major impact on the evaluation of liver, pancreas and bile diseases, there are a lot of indications for Nuclear Medicine procedures. These include new investigational procedures like esophageal scintigraphy, proof of bleeding sites, scintigraphy of inflammatory diseases, and intestinal resorption tests. Further, immunoscintigraphy with radiol- elled antibodies has gained wide-spread application especially in colon...

During the last decade many significant advances have been made in the in vivo diagnosis of disease. An area of partic- ular success has been the application of nuclear medical procedures to the detection of cardiac disease. Not only is it possible to detect infarction or ischemia by scintigraphic techniques but by the use of labelled metabol- ites and analogues of potassium the viability of myocardial tissue can be evaluated. The efficiency of the heart pump can be calculated and wall motility observed in one simple proce- dure. The use of ultra short life radionuclides has made the...
