Learning objectives

The objectives of this study are: 1. Provide a simple and concise key technical aspects of image post-processing, with particular attention to those with greater practicality. 2 Review basic concepts and advanced techniques of post-processing. 2. Describe the role of the technician in the postprocessing techniques.

Background

Post-processing of CT and MRI images has been increasing due to a large increase in clinical demand, becoming indispensable in daily practice. Radiographers in training require advanced formation in this area to assist radiologists in diagnosis workflow, which reduces the reading and report turnaround times dedicated to each study.

Imaging findings OR Procedure details

Postprocessing of CT and MRI images has proven to be a valuable tool in a variety of clinical applications due toits ability to provide additional diagnostic information. It has applications in various organs and systems (neuroradiology, musculoskeletal, cardiovascular, chest, abdomen...). It is essentialto haveimage excellentquality original data toperformance a clinical useful post-processing image. Posprocessing techniques allow ustoobtain anatomicalinformationfrom the originalimages and also give us functional and molecular information. We describe technical aspects and clinical applications of image post-processing techniques and wereviewfrom basic conceptsto more advanced...

Conclusion

Radiologic technologists has a fundamental role in the post-processing of the images due to the increased demand. It is therefore essential for radiographer to know and understand different techniques in order to obtain the best possible results, facilitate work of radiologysts and optimize time and improve productivity.
