Objectives Review the normal distribution of commonly used radiopharmaceuticals. Review the key steps in tracer preparation, administration and imaging to prevent abnormal distribution and images. Presenting incidental findings due to unexpected tracer distribution in an interactive case based review.
Methods We will present the normal distribution of selected, commonly used radiopharmaceuticals to help the reader differentiate between different types of normal whole body scans. Next, we will present key steps in the different acquisition protocols to help prevent image alterations which may results in clinical misdiagnosis. Finally, we will review selected abnormal images with incidental findings in a case base review.
Results Nuclear Medicine imaging technology encompasses a complex integration of physics and chemistry and requires the knowledge of physiology, pathophysiology, pathology, histology, radiology, internal medicine, endocrinology, hematology, radiation oncology, cardiology and many other aspects of medicine. Prior to the interpretation of a Nuclear Medicine procedure, complex activities are performed behind the scenes. Each technique or radiopharmaceutical is unique in its pathway and requires the proper use and indication. Some radiotracers can be tailored for different indications by changing their route of administration or pair it with a pharmaceutical. Understanding the mechanism, distribution and clearance of radiotracers may be challenging. Acknowledging the fundamentals of nuclear medicine, which will be delineated in this presentation, will allow the interpreter to be fully aware and prepared for any challenges they may face in their daily practice.
Conclusions At the end of this presentation the practitioners will be able to recognize normal images among commonly used nuclear medicine studies. The reviewer will also be able to recognize abnormal findings, selected common artifacts and technical errors. RESEARCH SUPPORT:
