In 2012, the Foundation of the American Society of Neuroradiology (Foundation), American College of Radiology (ACR), and American Association for Women Radiologists (AAWR) established an award to provide leadership opportunities for women in neuroradiology and/or radiology overall. Since neuroradiologists must be leaders in the field, this award is for mid-career women with demonstrated experience and promise for leadership in neuroradiology and/or radiology overall. The objectives are to provide the award recipient with additional skills and insights to enhance opportunities for advancement.

The award recipient will receive funding to cover tuition and transportation costs to attend the ACR 2017 Radiology Leadership Institute Summit in conjunction with Babson College in Wellesley, Massachusetts, to be held at the Babson Executive Conference Center, Sept. 7-10, 2017. All other expenditures will be at the expense of the award recipient.

Eligible applicants must have a MD degree or DO degree, plus subspecialty certification in neuroradiology, or its equivalent for international candidates. Applicants must have demonstrated experience and promise for leadership in neuroradiology/radiology, and must be a member of ASNR, ACR, and AAWR prior to Jan. 1, 2017. Strong consideration will be given to applicants from practices and institutions that show a commitment to the applicant’s career development.

The deadline for receipt of applications and required attachments is March 1, 2017; late applications will not be accepted. Applications must be sent electronically, as indicated in the instructions.

Mueller-Huelsbeck S, Jahnke T. Complications in Vascular Interventional Therapy: Case-Based Solutions. Thieme; 2016; 280 pp; 540 ill; $159.99

Mueller-Huelsbeck and Jahnke cover

Steve Harvey, the entertainer who mistakenly crowned the wrong woman as Miss Universe 2015, once said, “Failure is a great teacher, and I think when you make mistakes and you recover from them and you treat them as valuable learning experiences, then you’ve got something to share.” While mistakes in medicine are never as laughable as his, this quote underscores one of the most powerful teachers in medicine: mistakes. Winston Churchill said, “All men make mistakes, but only wise men learn from their mistakes.” While local morbidity and mortality conferences allow groups to learn from one individual’s mistakes, fear of legal action or professional embarrassment engenders reticence to present and publish our own mistakes on a national or international stage. However, physicians everywhere know the value of learning from complications. For example, by popular demand, a local morbidity and mortality conference in Austria has morphed into a major international conference (International Conference on Complications in Interventional Radiology sponsored by the Cardiovascular and Interventional Radiology Society of Europe, or CIRSE).

This book presents a total of 106 cases (illustrated with 540 images). Each case provides patient history, initial/intended treatment, problems encountered, a list of possible bailouts of the complication, an explanation of which route was chosen and how it was carried out, and finally, an analysis of the complication. What makes the cases such good learning experiences is the fact that, despite many awful-looking initial complications, only one of the patients died (but likely because of his underlying condition rather than the complication). Therefore, in reading this book, one can learn of the plethora of endovascular complications that exist, and hopefully learn how to prevent their occurrence, or at the very least, …

Scleritis is a rare vision-threatening condition that can occur isolated or in association with other orbital abnormalities and whose etiology is typically inflammatory/noninfectious, either idiopathic or in the context of systemic disease. The authors analyzed 11 cases of scleritis in which CT and/or MR imaging were performed during the active phase of disease and assessed the diagnostic utility of these techniques. The most important imaging findings of scleritis were scleral enhancement, scleral thickening, and focal periscleral cellulitis. MR imaging is the recommended imaging technique.

Summary

Figure 1 from paper
Asynchronous IOID with scleritis. A, CECT depicts outward, eccentric thickening and enhancement of the right globe wall with focal periscleral cellulitis (black arrow), compatible with posterior scleritis. There is associated pre- and postseptal cellulitis (white arrow) and proptosis. B, CECT 18 months after examination (A) shows almost identical findings in the left orbit. Black and white arrows point to the scleritis and cellulitis, respectively. Notice the complete resolution of the alterations of the right orbit. Also, notice involvement of the tendon of the lateral rectus anteriorly (dashed arrow).

Scleritis is a rare, underdiagnosed vision-threatening condition that can occur isolated or in association with other orbital abnormalities. The etiology of scleritis is mainly inflammatory noninfectious, either idiopathic or in the context of systemic disease. Ultrasonography remains the criterion standard in diagnostic imaging of this condition but might prove insufficient, and studies on the diagnostic value of CT and MR imaging are lacking. We retrospectively analyzed 11 cases of scleritis in which CT and/or MR imaging were performed during the active phase of disease and assessed the diagnostic utility of these techniques. The most important imaging findings of scleritis were scleral enhancement, scleral thickening, and focal periscleral cellulitis. MR imaging is the recommended imaging technique, though posterior scleritis also can be accurately diagnosed on

Editor’s Choice

Nineteen patients with schizophrenia and 11 matched healthy controls underwent MR imaging and multivoxel point-resolved 1H-MRS at 3T to obtain their hippocampal gray matter absolute NAA, Cr, and Cho concentrations. Patients’ average hippocampal GM Cr concentrations were 19% higher than those of controls. NAA and Cho showed no differences. The authors conclude that the findings suggest the hippocampal volume deficit in schizophrenia is not due to net loss of neurons, which is in agreement with histopathology studies but not with prior 1H-MR spectroscopy reports. Elevated Cr would be consistent with hippocampal hypermetabolism.

Abstract

Figure 2 from paper
Upper: A, Axial MPRAGE image from a 51-year-old female patient (16 in Table 1) superimposed on the VOI (in yellow). Orange lines show the 9 × 6 voxel CSI grid; voxels that passed the selection criteria to calculate the NAA concentration are highlighted in transparent red. B–D, SPM12-generated WM (B), GM (C), and CSF (D) masks also superimposed on the VOI CSI grid and selected voxels. Note the n ≥ 2 voxels that “passed” the selection criteria described in the “Materials and Methods” section.

BACKGROUND AND PURPOSE

Schizophrenia is well-known to be associated with hippocampal structural abnormalities. We used 1H-MR spectroscopy to test the hypothesis that these abnormalities are accompanied by NAA deficits, reflecting neuronal dysfunction, in patients compared with healthy controls.

MATERIALS AND METHODS

Nineteen patients with schizophrenia (11 men; mean age, 40.6 ± 10.1 years; mean disease duration, 19.5 ± 10.5 years) and 11 matched healthy controls (5 men; mean age, 33.7 ± 10.1 years) underwent MR imaging and multivoxel point-resolved spectroscopy (TE/TR, 35/1400 ms) 1H-MRS at 3T to obtain their hippocampal GM absolute NAA, Cr, Cho, and mIns concentrations. Unequal variance t tests and ANCOVA were used to compare patients with controls. Bilateral volumes from manually outlined hippocampal
