Abstract
There are a wide variety of gynecologic devices encountered on pelvic imaging which may not be the focus or primary reason for imaging. Such devices include pessaries, menstrual products, radiation therapy devices, tubal occlusion devices, and contraceptive devices, including intrauterine devices and intravaginal rings. This manuscript offers a comprehensive review of multimodality imaging appearances of gynecologic devices encountered on pelvic imaging and discusses device indications, positioning, and complications.

Abstract
INTRODUCTION Strict safety practices are essential to ensure the safety of patients and staff in Magnetic Resonance Imaging (MRI). Training regarding the fundamentals of MRI safety is well-established and commonly agreed upon. However, more complex aspect of screening patients, such as image review or screening of unconscious patients/patients with communication difficulties is less well discussed. The current UK and USA guidelines do not suggest the use of communication training for MRI staff nor indicate any training to encourage reviewing images in the screening process. This review aims to map the current guidance regarding safety and patient screening training for MRI diagnostic and therapeutic radiographers. METHODS A systematic search of PubMed, Trip Medical database and Radiography journal was conducted. Studies were chosen based on the review objectives and pre-determined inclusion/exclusion criteria using the PRISMA-ScR framework. RESULTS Twenty-four studies were included in the review, which identified some key concepts including MRI safety training and delivery methods, screening and communication, screening of unconscious or non-ambulatory patients and the use of imaging. CONCLUSION Training gaps lie within the more complex elements of screening such as the inclusiveness of question phrasing, particularly to the neurodivergent population, how we teach radiographers to screen unconscious/unresponsive patients and using imaging to detect implants. IMPLICATIONS FOR PRACTICE The consequences of incomplete or inaccurate pre-MRI safety screening could be the introduction of unexpected implants into the scanner or forgoing MRI for a less desirable modality. The development of enhanced training programs in implant recognition using imaging and communication could complement existing training.

Abstract
Ureteral involvement by a tumor is common, and both partial and complete obstructions can result in symptoms that are distressing and debilitating, especially in cancer patients for whom the resection of the primary tumor is not considered an option. Maintaining ureteric patency in these patients is a challenge. In addition, in cases where a patient has undergone nephroureterectomy due to primary transitional cell cancer, it becomes necessary to decompress the urinary tract to preserve the contralateral kidney from irreversible damage. This is possibly due to ureteral stenting, both retrograde and anterograde, and percutaneous nephrostomy (PCN). Since imaging plays an important role in the routine monitoring of stents, their more and more increasing use requires radiologists to be familiar with these devices, their correct position, their potential complications, and their consequences. The aim of this review is to offer a comprehensive review of the imaging features of some urinary stents and to show the complications encountered in cancer patients as a direct consequence of an invasive diagnostic or therapeutic procedure. Specifically, we focus on ureteral stents and PCN.

Abstract
Central venous and arterial catheters are among the most commonly assessed support devices by radiologists. The position of these catheters must be carefully assessed to ensure proper placement, as malpositioning may lead to life-threatening consequences. Therefore, it is important for radiologists to understand the anatomy of the central vessels and the expected location of catheters. While this can be difficult in small children and especially in neonates, knowledge of the expected course and ideal termination of catheters allows for recognition of a malpositioned line, which may be unsuspected clinically. The purpose of this article is to discuss appropriate positioning of central catheters in pediatric patients, focusing primarily on venous catheters. We also propose a new radiographic sign to recognize, the undulating line sign, as an indication of an inappropriate course of a newly placed venous catheter.

Abstract
A variety of different external and internal medical devices are used in the acute setting to maintain life support and manage severely injured and unstable trauma or emergency patients. These devices are inserted into the acutely ill patient with the specific purpose of improving outcome, but misplacement can cause additional morbidity and mortality. Consequently, meaningful interpretation of the position of devices can affect acute management. Some devices such as nasopharyngeal, nasogastric and endotracheal tubes and chest and surgical drains are well known to most clinicians, however, little formal training exists for radiologists in composing their report on the imaging of these devices. The novice radiologist often relies on tips and phrases handed down in an aural tradition or resorts to phrases such as: "position as shown". Furthermore, radiologists with limited experience in trauma might not be familiar with the radiological appearance of other more specific devices. This review will focus on the most common medical devices used in acute trauma patients, indications, radiological appearance and their correct and suboptimal positioning.

Abstract
When compared with chest radiographs, medical devices of the abdomen and pelvis are less frequently seen. However, with recent advances in technology the interpreting radiologists are seeing more medical objects on these radiographs. The identification of these devices and materials are crucial for not only enabling the radiologist to understand the underlying background pathology but also for evaluating any related complications. An online survey of literature showed our review article to be the most detailed. In this first part of our two-part series, we discuss about the various gastrointestinal and vascular devices and materials seen on abdominal and pelvic radiographs.

Abstract
의료기구들이 발달하면서 복부 및 골반 내에 이식되거나 거치되는 의료기구들이 다양해졌다. 흔하게 사용되는 기구들의 영상의학 소견은 영상의학과 의사들에게 매우 익숙하지만, 상대적으로 사용 빈도가 낮거나 새로운 형태의 기구들의 영상의학 소견은 잘 알려져 있지 않다. 또한 환자에 대한 임상정보가 제한적일 경우 이런 새로운 형태의 의료기구들은 잘못 해석되거나 놓치기 쉽다. 그러므로 복부 및 골반 내 의료기구들의 영상의학 소견을 인지하는 것은 기구들의 올바른 위치를 평가하고, 이와 관련된 합병증을 평가하는데 있어 매우 중요하다. 본 논문에서는 다양한 복부 및 골반 내 의료기구들과 이와 관련된 합병증의 영상의학 소견을 소개하고자 한다.

Abstract
Medical devices which have been erroneously retained postoperatively has been a persisting problem encountered over many decades, despite rigid protocols and preventative measures being put in place. We present a case of a retained wound protector detected on CT following abdominal surgery, the first published report of its kind to our knowledge. Radiologists reporting the images should be familiar with commonly used medical devices. This case also highlights the importance of reviewing the CT scout imaging as an essential part of the study, particularly in the recognition of foreign bodies or medical devices. We re-emphasise the importance of effective and timely communication with the surgical team, should there be any suspicion of retained surgical appliance.

Abstract
The diagnosis of abdominal wall pathology is often obvious on clinical physical examination; however, multimodality imaging often yields incidental, and occasionally important, findings aiding in assessing the overall clinical picture. While various hernias are common, there are numerous other causes of abdominal wall pathology. Knowledge of these entities is crucial to avoid misinterpretation and assure proper radiological judgment.

Abstract
X-rays were discovered by Wilhelm Röntgen in 1895. Within one year, benefits of x-rays, such as visualization of fractures, and detriments, such as x-ray dermatitis, were recognized. Nobel Laureates Pierre and Marie Sklodowska Curie discovered the radioactive element radium in 1898, and a year later the application of radiation to cure cancer was reported. A significant price was paid for this: Marie Curie died of aplastic anemia related to her radiation exposure, and her daughter Irene Joliot Curie, Nobelist for radiochemical research, died of radiation-induced leukemia. Internationally developed radiation protection recommendations were formalized starting in the late 1920s. The increasing use of ionizing radiation in medical diagnosis and radiation therapy has brought significant societal benefits. Known risks of therapeutic radiation include coronary artery disease and secondary malignancy. However, recently concerns have been raised of possible very small but incremental increases in malignancies due to diagnostic medical radiation. Patients are largely unaware of, and referring physicians and even radiologists often underestimate, the carcinogenic effects of radiation. There is a need to determine the appropriateness of imaging tests that use ionizing radiation prior to performance; optimize imaging protocols to reduce unnecessary radiation; include patients in the decision process and encourage and enable them to track their radiation exposure; and promote education about medical radiation to patients, referring physicians, radiologists, and members of the public. The basic radiation protection principles of justification, optimization, and application of dose limits still pertain.

Abstract
Computed tomography scout view is a mode of operating a CT system. It is generally used to prescribe CT slices and to display slice locations rather than for direct diagnosis. However, we found that a careful study of CT scout view can contribute significantly to the diagnosis. We show seven abdominal, two chest and two head CT, where the study of CT scout view allowed diagnoses to be made that were not readily apparent from the axial slices.

Uterovesical perforation is an uncommon complication in patients with intrauterine devices (IUD). When this complication occurs, intravesical lithiasis is often associated. We present two cases of uterovesical perforation with a description of the radiological findings and a review of the literature.

Abstract
Numerous medical devices are used in the chest and fewer in the abdomen and pelvis. They are frequently seen on various radiological studies in daily practice. Knowing the specific name of the device is not important. However, knowing the proper positioning and function of the device is necessary. It is a duty of the reporting radiologist to recognize the malpositioning or breakage of a medical device and to inform the responsible physician promptly, since these complications can have undesirable consequences and sometimes a fatal outcome.

Abstract
This gallery of medical devices illustrates a multitude of common devices in the head, neck, spine, chest, and abdomen that are found in daily radiologic practice (orthopedic devices for the extremities and pelvis were illustrated in Part 1). All these medical devices have been more thoroughly discussed in the previous articles in this medical devices series and in other detailed references. The present article is a comprehensive overview of these devices and provides a quick reference for identifying an unfamiliar device. It is intended to allow the reader to identify a device generically and to understand its purpose. It is important to recognize the presence of a device, understand its purpose and proper function, and recognize the complications associated with its use. Knowing the specific or proper brand name of every device is not important and frequently not possible. New devices are constantly being introduced, although most of them are variations of a previous device. Sometimes, so many devices are used in a patient's treatment that they obscure important anatomy and pathologic conditions (Fig 1). Herein, we present an overview of the many medical devices frequently used in the head, neck, and spine, including a halo device, aneurysm clips, spinal fusion devices, deep brain electrodes, sacral nerve stimulator, and vertebroplasty (Figs 2-9). We also illustrate numerous chest medical devices that are seen daily by almost all radiologists. These devices include a multitude of extrathoracic and intrathoracic apparatus, ranging from intravenous catheters to oxygen tubing and electrocardiographic leads, central venous catheters, chest tubes, endotracheal and feeding tubes, cardiac valves, coronary artery bypass stents, pacemakers, internal cardiac defibrillators, ventricular assist devices, and total artificial hearts (the latter two devices are frequently encountered in many large medical centers) (Figs 10-26). We also present medical devices of the abdomen and pelvis, which can be grouped into four major categories: intestinal tubes, genitourinary apparatus, postoperative apparatus, and vascular devices (Figs 27-47). For a detailed discussion of a particular device, the reader should refer to the appropriate references cited.
