Apply to Be the Radiology Associate Editor for Podcasts

RSNA is looking for a podcast editor to serve as the host of the Radiology podcast.

 

The Radiology podcast editor will work with David A. Bluemke, MD, PhD, editor of Radiology to determine which articles will be summarized for the Radiology podcast that publishes twice every month. This editor will also develop a script that summarizes each of the determined articles, record audio summaries for RSNA Publications staff to edit and work with RSNA Publications staff to develop a consistent timeline for releasing content. The time commitment for this position is 10 hours per episode or 10-20 hours/month. 

 

RSNA will cover the cost of recording equipment (microphone) or use of a professional recording studio for this position.  Once this new editor is comfortable with the current format of recording podcasts, other formats, such as author interviews, will be considered. In addition, the podcast editor may be asked to read supplied marketing/advertising material that may promote upcoming RSNA programs and meetings.

 

If you are interested in applying for the position, email radiology@rsna.org for more information and apply by Oct. 2, 2020.

Adhesive Small Bowel Obstruction: Predictive Radiology to Improve Patient Management

Adhesive small bowel obstruction (SBO) remains one of the leading causes of emergency room visits and is still associated with high morbidity and mortality rates.

Because the management of adhesive SBO has shifted from immediate surgery to nonoperative treatment in the absence of ischemia, it is crucial to rapidly detect or predict strangulation, which requires emergent surgery. CT is now established as the best imaging technique for the initial assessment of patients suspected of having adhesive SBO. CT helps confirm the diagnosis of mechanical SBO, locate the site of obstruction, establish the cause, and detect complications.

A new article in Radiology reviewed the role of imaging in answering specific questions to help predict the management needs of each patient.

Marc Zins, MD, Saint Joseph Hospital, Paris, France, and colleagues provided an update on the best CT signs for predicting ischemia and a need for bowel resection.

“When evaluating patients suspected of having adhesive small bowel obstruction, radiologists play a pivotal role and should address the questions that will affect the management strategy. By using CT as the imaging modality of choice and searching for highly specific CT findings, radiologists can now accurately predict the presence of ischemia, the need for bowel resection related to bowel infarction, and the outcome of nonoperative management,” the authors write.

Diagrams illustrate the open-loop and closedloop mechanisms of adhesive small bowel obstruction. (a) In open-loop obstruction, a single transition zone is seen between the dilated afferent loop and the collapsed efferent loop. The risk of vascular compromise is low. (b) In closed-loop obstruction, the bowel lumen is obstructed at two sites located next to each other, at the entry and exit points of the loop. The risk of vascular compromise is high since the adjacent mesenteric vessels (arrow) are affected.

Relationship between Coronary Iodine Concentration Determined Using Spectral CT and the Outcome of Percutaneous Coronary Intervention in Patients with Chronic Total Occlusion

Coronary chronic total occlusion (CTO) is an obstructive coronary artery disease for which patients are commonly referred for percutaneous coronary intervention (PCI). But despite recent technological advances and improved interventional strategies, the success rate of PCI for the revascularization of CTO has remained low.

Coronary CT angiography is a valuable imaging method for the characterization of CTO. However, the visual assessment of contrast enhancement in the occluded segment of the CTO on coronary CT angiograms may be subjective depending on the reader’s experience. Spectral CT based on the dual-energy CT technique can quantify iodine content, which is a major component of the contrast media used at coronary CT angiography.

A new study in Radiology: Cardiothoracic Imaging measured the coronary iodine concentration (CIC) of CTO lesions with coronary CT angiography by using spectral CT and to evaluate the feasibility of CTO-CIC in the assessment of the outcome of PCI for CTO. Jeong Yoon Lee, MD, Korea University Anam Hospital, Seoul, Republic of Korea, and colleagues looked at 50 consecutive patients who underwent preprocedural coronary CT angiography with spectral CT prior to their staged PCI for CTO. Iodine-no-water maps with spectral CT provided the CIC at proximal CTO-CIC.

“Our results showed that patients with a failed PCI had significantly lower mean CTO-CIC than those who underwent a successful PCI. By using spectral CT for coronary angiography before PCI for CTO, a low CIC at the entry of the CTO lesion is associated with failure of successful antegrade PCI for the management of CTO,” the authors conclude.

Anatomy, Imaging, and Pathologic Conditions of the Brachial Plexus

The brachial plexus is an intricate anatomic structure with an important function: providing innervation to the upper extremity, shoulder and upper chest. Owing to its complex form and longitudinal course, the brachial plexus can be challenging to conceptualize in three dimensions, complicating evaluations in standard orthogonal imaging planes.

A new article in RadioGraphics provides radiologists with a firm understanding of the anatomy of the various components of the brachial plexus to facilitate accurate detection and localization of pathologic entities.

Brian M. Gilcrease-Garcia, MD, Northwestern University, Chicago, and colleagues, reviewed clinical reporting of brachial plexus imaging findings to understand how imaging may affect patient care and provided an image-rich review of the brachial plexus, with emphasis on multimodality comparisons, including ultrasound, CT and MRI findings.

“Brachial plexopathy can be challenging to diagnose and manage. The medical history and physical examination findings are the mainstays for diagnosis, but imaging can be used to confirm physical examination and electrodiagnostic findings, localize sites of involvement to assist in preoperative planning, and assess for underlying structural or neoplastic anomalies. Familiarity with the anatomy and nerve distributions of the brachial plexus and the spectrum of associated imaging appearances is important for radiologic evaluation of this structure,” the authors conclude.

Complete rupture of the entire left brachial plexus at the level of the trunks after a fall, representing neurotmesis with fifth-degree injury. (a) Axial nonenhanced CT image of the cervical spine shows a hematoma (long yellow arrow) obliterating the fat within the left interscalene triangle, compared with a normal- appearing right interscalene triangle (short white arrow); this finding is highly suggestive of neurovascular injury. (b) Coronal CT angiogram (MIP rendering) of the left upper extremity shows cutoff of the left axillary artery (arrow), consistent with arterial transection, which was confirmed surgically.
