Learning objectives To review and illustrate the wide variety of medical abdominal devices that may be found in many radiological studies, such as radiographs, US, CT and MRI. To know their indications and to recognize their correct location and possible complications. Background There is a wide variety of medical abdominal devices. Nowadays, because of the increasing number of imaging studies being performed, it is very common to find medical abdominal devices in different techniques such as radiographs, ultrasonographies, computed tomographies and magnetic resonances. Some abdominal devices are very common and have a typical radiological appearance, while others are less common and therefore more difficult to recognize. Moreover, medical abdominal devices are continually being developed and often have unknown or unexpected radiographic appearances, which difficults their recognition. It is vital for radiologists not only to be familiarized with medical abdominal devices and to be capable of recognizing them, but to do a systematic reading of imaging studies in order to avoid their overlook. Thus, their recognition will facilitate the interpretation of radiologic studies as well as the evaluation of their correct localization and possible complications. Imaging findings OR Procedure details Nasogastric, feeding and vesical tubes, as well as urinary stents, are the more common and traditional abdominal devices with which every radiologist should be familiarized. Gastrostomy, colostomy and other gastrointestinal tubes, biliar drainages, nephrostomies, different types of stents, methalic coils, endoprostheses and inferior vena cava filters, as well as orthopedic devices, IUDs, pessaries, and those derived from abdominal wall defect surgery are less common. In this review it will be shown how to recognize them and evaluate their localization. Page 2 of 34

Penile prosthesis, ginecological brachitherapy, devices derived from tubal ligation and vasectomy, embolization material, porthosystemic shunts and neurostimulators are more rare devices and will be illustrated. Fig. 3 Page 3 of 34

Fig. 34 Conclusion The use of abdominal medical devices is every time more extended, so that it is very common to find them in different types of radiological studies. Therefore, it is vital for the radiologist to know and be familiarized with the wide spectrum of abdominal devices in order to be able to evaluate their appropriated location and possible complications.
