Contrast-Induced Nephropathy: Identifying the Risks, Choosing the Right Agent, and Reviewing Effective Prevention and Management Methods

With the rise in the use of intravenous iodinated contrast media for both computed tomography scan and angiographic studies, there is a greater likelihood of complications. One of the most well-known adverse effects is contrast-induced media nephropathy, which is also called contrast-induced acute kidney injury. This is third most common cause of hospital acquired acute renal failure. It is associated with an increase in morbidity, mortality, and greater financial burden on healthcare system. Because of these factors, it is important for the radiologist to not only recognize risk factors, as well as the signs and symptoms, but also to know how to manage patients appropriately.

After-Hours Radiology: Challenges and Strategies for the Radiologist.

OBJECTIVE Because of the increase in the use of 24-hour-a-day 7-day-a-week real-time radiologic interpretation, radiologists more frequently perform after-hours work. The purpose of this article was to examine the challenges arising from after-hours work and describe evidence-based strategies meant to limit the adverse physical and psychologic stresses of after-hours work. CONCLUSION Working nontraditional hours affects a radiologists health, social life, professional productivity, and possibly interpretive accuracy. Appropriate attention to these factors and targeted countermeasures can optimize the professional development and personal well-being of radiologists working after hours.

Contrast Media Extravasation of Computed Tomography and Magnetic Resonance Imaging: Management Guidelines for the Radiologist

Intravenous contrast administration has been of great importance in diagnostic radiology, but it is not without risks either due to the local, systemic allergic reactions or due to subcutaneous extravasation of contrast media. Subcutaneous contrast medium extravasationis an infrequent, yet a well-recognized complication. However, most incidents are minor and can be managed conservatively, but there are a few cases that require immediate surgical intervention. This article discusses the risks factors, clinical manifestations, and conservative and surgical approaches of subcutaneous contrast media extravasation for both computed tomography and magnetic resonance imaging.

Imaging of Traumatic Injuries to the Scrotum and Penis

OBJECTIVE The purpose of this article is to review scrotal and penile anatomy, the role of ultrasound in evaluating scrotal and penile trauma, and the vast spectrum of sonographic manifestations of scrotal and penile trauma. CONCLUSION Scrotal and penile trauma is an uncommon type of trauma injury. However, knowledge of scrotal and penile anatomy and the appropriate imaging findings associated with acute traumatic injuries is important in establishing the correct diagnosis. Sonography is considered the first choice of imaging modalities in establishing a diagnosis and triaging patients into surgical and nonsurgical treatment.

Burnout in Radiology

Burnout is a psychological syndrome that arises in the setting of prolonged work-related stress. Although its specific manifestations are highly variable, the core features of burnout include emotional exhaustion, callousness or apathy towards patients or peers, and feelings of personal inadequacy. Burnout can have profound consequences for the affected physician, his or her patients, and the health care system at large. Increased rates of substance abuse, depression, and suicide have been linked to physician burnout, as have medical errors and lapses in patient safety. Disruptive workplace behaviors, such as presenteeism (which is reduced productivity due to physical or emotional dysfunction), absenteeism (which is nonparticipation in work), high employment turnover, and early retirement also have been linked to physician burnout and depression. In this article, we review causes, preventive measures and possible solutions for physician burnout.

Dual-phase CT for the assessment of acute vascular injuries in high-energy blunt trauma: the imaging findings and management implications

Acute vascular injuries are the second most common cause of fatalities in patients with multiple traumatic injuries; thus, prompt identification and management is essential for patient survival. Over the past few years, multidetector CT (MDCT) using dual-phase scanning protocol has become the imaging modality of choice in high-energy deceleration traumas. The objective of this article was to review the role of dual-phase MDCT in the identification and management of acute vascular injuries, particularly in the chest and abdomen following multiple traumatic injuries. In addition, this article will provide examples of MDCT features of acute vascular injuries with correlative surgical and interventional findings.

The History of US: From Bats and Boats to the Bedside and Beyond: RSNA Centennial Article

The article traces the emergence of modern US from knowledge accumulated gradually over 2 centuries from scientific observation, including experiments with flying bats, underwater church bells, iceberg detection devices, and imaging systems that required the patient to be submerged in a tank of water.

Errors in imaging of traumatic injuries.

Abstract The advent of multi-detector computed tomography (MDCT) has drastically improved the outcomes of patients with multiple traumatic injuries. However, there are still diagnostic challenges to be considered. A missed or the delay of a diagnosis in trauma patients can sometimes be related to perception or other non-visual cues, while other errors are due to poor technique or poor image quality. In order to avoid any serious complications, it is important for the practicing radiologist to be cognizant of some of the most common types of errors. The objective of this article is to review the various types of errors in the evaluation of patients with multiple trauma injuries or polytrauma with MDCT.

Imaging findings in elder abuse: a role for radiologists in detection

Purpose Emergency department assessment represents a critical but often missed opportunity to identify elder abuse, which is common and has serious consequences. Among emergency care providers, diagnostic radiologists are optimally positioned to raise suspicion for mistreatment when reviewing imaging of geriatric injury victims. However, little literature exists describing relevant injury patterns, and most radiologists currently receive neither formal nor informal training in elder abuse identification. Methods We present 2 cases to begin characterisation of the radiographic findings in elder abuse. Results Findings from these cases demonstrate similarities to suspicious findings in child abuse including high-energy fractures that are inconsistent with reported mechanisms and the coexistence of acute and chronic injuries. Specific injuries uncommon to accidental injury are also noted, including a distal ulnar diaphyseal fracture. Conclusions We hope to raise awareness of elder abuse among diagnostic radiologists to encourage future large-scale research, increased focus on chronic osseous findings, and the addition of elder abuse to differential diagnoses.

Magnetic Resonance Imaging of Abdominal and Pelvic Pain in the Pregnant Patient

The utility of MR imaging in evaluating abdominal and pelvic pain in the pregnant patient is discussed. Details regarding the indications, technical aspects, and imaging findings of various common abdominal and pelvic abnormalities in pregnancy are reviewed.
