Role of dual energy CT to improve diagnosis of non-traumatic abdominal vascular emergencies.

Computed tomography angiography (CTA) is the modality of choice to evaluate abdominal vascular emergencies (AVE). CTA protocols are often complex and require acquisition of multiple phases to enable a variety of diagnosis such as acute bleeding, pseudoaneurysms, bowel ischemia, and dissection. With single energy CT (SECT), differentiating between calcium, coagulated blood, and contrast agents can be challenging based on their attenuation, especially when in small quantity or present as a mixture.

Experience With Iterative Reconstruction Techniques for Abdominopelvic Computed Tomography in Morbidly and Super Obese Patients.

Objective: The aim of this study was to investigate the diagnostic performance of abdominopelvic computed tomography (CT) images reconstructed using filtered back projection (FBP) and iterative reconstruction (IR) algorithms in morbidly and super obese patients.

Materials And Methods: One hundred eighty-seven abdominopelvic CT examinations in portal venous phase were performed between February 2015 and February 2016 in 182 patients (mean age = 52 years, mean body mass index = 45.5).

Rating and Classification of Incident Reporting in Radiology in a Large Academic Medical Center.

The purpose of this article is to provide a rate of safety incident report of adverse events in a large academic radiology department and to share the various types that may occur. This is a Health Insurance Portability and Accountability Act compliant, institutional review board-approved study. Consent requirement was waived.

How often are Patients Harmed When They Visit the Computed Tomography Suite? A Multi-year Experience, in Incident Reporting, in a Large Academic Medical Center.

Objectives: Our goal is to present our multi-year experience in incident reporting in CT in a large medical centre.

Methods: This is an IRB-approved, HIPAA-compliant study. Informed consent was waived for this study.

Rates of safety incident reporting in MRI in a large academic medical center.

Purpose: To describe our multiyear experience in incident reporting related to magnetic resonance imaging (MRI) in a large academic medical center.

Materials And Methods: This was an Institutional Review Board (IRB)-approved, Health Insurance Portability and Accountability Act (HIPAA)-compliant study. Incident report data were collected during the study period from April 2006 to September 2012.

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.

Detecting Aortic Graft Complications: A Spectrum of Computed Tomography Findings.

Endovascular aneurysm repair (EVAR) is a successful technique as well as an excellent alternative to the surgical management of abdominal aortic aneurysms. EVAR has improved the mortality and morbidity of many patients who would have otherwise suffered greatly from the consequences of abdominal aortic aneurysms. However, EVAR is not without complications.

Safety incident reporting in emergency radiology: analysis of 1717 safety incident reports.

The aim of this article is to describe the incidence and types of safety reports logged in the radiology safety incident reporting system in our emergency radiology section over an 8-year period. Electronic incident reporting system of our institute was searched for the variables in emergency radiology. All reports from April 2006 to June 2014 were included and deindentified.

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.

Dual-energy computed tomography (DECT) in emergency radiology: basic principles, techniques, and limitations.

Recent advances in computed tomography (CT) technology allow for acquisition of two CT datasets with different X-ray spectra. There are different dual-energy computed tomography (DECT) technical approaches such as: the dual-source CT, the fast kilovoltage-switching method, and the sandwich detectors technique. There are various postprocessing algorithms that are available to provide clinically relevant spectral information.
