Recurrence of Colonic Diverticulitis: Identifying Predictive CT Findings-Retrospective Cohort Study.

Purpose To identify computed tomographic (CT) findings that are predictive of recurrence of colonic diverticulitis. Materials and Methods Institutional review board approval was obtained for this HIPAA-compliant, retrospective cohort study. Six abdominal fellowship-trained radiologists reviewed the CT studies of 440 consecutive subjects diagnosed with acute colonic diverticulitis between January 2004 and May 2008 to determine the involved segments, maximum wall thickness in the inflamed segment, severity of diverticulosis, presence of complications (abscess, fistula, stricture, or perforation), and severity of the inflammation.

Effect of Template Reporting of Brain MRIs for Multiple Sclerosis on Report Thoroughness and Neurologist-Rated Quality: Results of a Prospective Quality Improvement Project.

Purpose: To assess the impact of structured reporting templates on the objective and subjective quality of radiology reports for brain MRIs in patients with multiple sclerosis (MS).

Methods: A HIPAA-compliant prospective quality improvement initiative was undertaken to develop and implement a 12-item structured reporting template for brain MRI examinations in patients with known or suspected MS based on published guidelines. Reports created 1 year before implementing the template served as the baseline.

Advanced Imaging Techniques of the Skull Base.

Although conventional imaging can depict the anatomy of the head and neck with exquisite detail, it often falls short in its ability to characterize tissue physiology and abnormality; this is especially seen in the posttherapy setting where benign posttreatment changes and recurrent tumors can show intense postcontrast enhancement and similar features on conventional imaging. Advanced imaging can evaluate tissue physiology and, along with conventional imaging, provide a more accurate assessment of the skull base. This article describes the technical details and clinical applications of different advanced imaging techniques with a primary focus on diffusion-weighted imaging.

"Concordance" Revisited: A Multispecialty Appraisal of "Concordant" Preliminary Abdominopelvic CT Reports.

Purpose: To determine whether resident abdominopelvic CT reports considered prospectively concordant with the final interpretation are also considered concordant by other blinded specialists and abdominal radiologists.

Methods: In this institutional review board-approved retrospective cohort study, 119 randomly selected urgent abdominopelvic CT examinations with a resident preliminary report deemed prospectively "concordant" by the signing faculty were identified. Nine blinded specialists from Emergency Medicine, Internal Medicine, and Abdominal Radiology reviewed the preliminary and final reports and scored the preliminary report with respect to urgent findings as follows: 1.

Multicenter Survey of Current Practice Patterns in Perfusion MRI in Neuroradiology: Why, When, and How Is It Performed?

Objective: Perfusion MRI is an advanced imaging technique with a number of potential neuroradiologic applications. However, there are few guidelines about the application of perfusion MRI in clinical practice. The purpose of this study was to assess when and how perfusion MRI is performed across national and international practices.

In-Person Communication Between Radiologists and Acute Care Surgeons Leads to Significant Alterations in Surgical Decision Making.

Purpose: The aim of this study was to determine if direct in-person communication between an acute care surgical team and radiologists alters surgical decision making.

Methods: Informed consent was waived for this institutional review board-exempt, HIPAA-compliant, prospective quality improvement study. From January 29, 2015 to December 10, 2015, semiweekly rounds lasting approximately 60 min were held between the on-call acute care surgery team (attending surgeon, chief resident, and residents) and one of three expert abdominal radiologists.

Pediatric MR Urography: Indications, Techniques, and Approach to Review.

Magnetic resonance (MR) urography is a valuable imaging modality for assessing disorders of the pediatric urinary tract. It allows comprehensive evaluation of the kidneys and urinary tract in children by providing both morphologic and functional information without exposing the child to ionizing radiation. Pediatric MR urography can be used to thoroughly evaluate renal and urinary tract abnormalities that are difficult to identify or fully characterize with other imaging techniques, and it has the potential to allow earlier diagnosis while decreasing the number of imaging studies performed.

Spontaneous regression of primary renal cell carcinoma following image-guided percutaneous biopsy.

Spontaneous regression of metastatic renal cell carcinoma (RCC) is a rare but well-described clinical phenomenon; spontaneous regression of nonmetastatic RCC has been reported far less frequently. We present three cases of primary RCC that regressed spontaneously following the image-guided biopsy that established their diagnosis. We briefly review the literature describing spontaneous regression of both primary and metastatic RCC and emphasize how knowledge of this phenomenon may be useful for abdominal imagers that perform renal biopsy or interpret postbiopsy follow-up studies.

Incidence of nonconfounded post-computed tomography acute kidney injury in hospitalized patients with stable renal function receiving intravenous iodinated contrast material.

Objective: The purpose of our investigation was to determine the frequency of proximate acute and chronic confounding risk factors for acute kidney injury (AKI) in a cohort of adult hospitalized patients with stable renal function who developed AKI following an intravenous (IV) contrast-enhanced computed tomography (CT) examination.

Materials And Methods: Institutional review board approval was obtained for this retrospective, Health Insurance Portability and Accountability Act-compliant investigation. Overall, 100 adult inpatients (50 males [mean age = 61 years, range: 24-94 years] and 50 females [mean age = 60 years, range: 20-95 years]) with stable pre-CT renal function who developed post-CT AKI using the Acute Kidney Injury Network (AKIN) laboratory criteria following an IV contrast-enhanced CT examination comprised the study population.

Mammary duct ectasia in a man with liver disease, end stage renal failure, and adjacent arteriovenous fistula.

Mammary duct ectasia is a rare finding in males. We report a case of mammary duct ectasia in a 58 year old male with liver failure and end stage renal failure. We discuss radiology findings of mammary duct ectasia as well as potential risk factors and management options for symptomatic male mammary duct ectasia.
