Image-Guided Percutaneous Gastrostomy Tube Placement is Safe in Patients Requiring Aspirin 325 mg.

Acad Radiol 2019 Mar 14. Epub 2019 Mar 14.

Department of Radiology, Duke University School of Medicine, Durham, North Carolina.

Rationale And Objectives: Requests for gastrostomy tube placement in patients on aspirin (ASA) 325 mg are common, particularly in patients following reconstructive surgery for head and neck cancer, but periprocedural guidelines and recommendations regarding management of high dose aspirin are inconsistent. The purpose of this study was to assess the bleeding risk of percutaneous gastrostomy tube placement in patients on ASA 325 mg.

Materials And Methods: This retrospective study of 213 patients who underwent image-guided "push" percutaneous gastrostomy tube placement compared rates of significant bleeding and other secondary outcomes (including all-cause mortality within 30 days, procedure-related mortality, bowel perforation, abdominal abscess, peritonitis, aspiration pneumonia, intraprocedural airway complications, and tube dislodgement) between patients maintained on ASA 325 mg and patients not on antiplatelet or anticoagulation therapy.

Acad Radiol 2019 Mar 6. Epub 2019 Mar 6.

University of Milano-Bicocca, Milan, Italy; Department of Diagnostic Radiology, ASST Papa Giovanni XXIII, Bergamo, Italy.

Early diagnosis of HCC is of paramount importance in order to enable the application of curative treatments. Among these, radiofrequency ablation (RFA) is actually considered the most effective ablative therapy for early stage hepatocellular carcinoma (HCC) not suitable for surgery. On the other hand, transarterial chemoembolization (TACE) represents the standard of care for intermediate stage HCC and compensated liver function. Read More

Discrimination Between Solitary Brain Metastasis and Glioblastoma Multiforme by Using ADC-Based Texture Analysis: A Comparison of Two Different ROI Placements.

Acad Radiol 2019 Feb 12. Epub 2019 Feb 12.

Department of Radiology, Guangzhou First People's Hospital, Guangzhou Medical University, 1 Panfu Road, Guangzhou, Guangdong 510108, China; Department of Radiology, Guangzhou First People's Hospital, School of Medicine, South China University of Technology, Guangzhou, Guangdong, China. Electronic address:

Rationale And Objectives: To explore the value of texture analysis based on the apparent diffusion coefficient (ADC) value and the effect of region of interest (ROI) placements in distinguishing glioblastoma multiforme (GBM) from solitary brain metastasis (sMET).

Materials And Methods: Sixty-two patients with pathologically confirmed GBM (n = 36) and sMET (n = 26) were retrospectively included. All patients underwent diffusion-weighted imaging with b values of 0 and 1000 s/mm, and the ADC maps were generated automatically. Read More

Coronary CT Angiography in Challenging Patients: High Heart Rate and Atrial Fibrillation. A Review.

Acad Radiol 2019 Feb 8. Epub 2019 Feb 8.

Centro Cardiologico Monzino, IRCCS, Milan, Italy; Department of Clinical Sciences and Community Health, Cardiovascular Section, University of Milan, Via C. Parea 4, 20138 Milan, Italy. Electronic address:

Despite several strategies have been developed by different vendors to improve image quality and diagnostic accuracy of coronary CT angiography performed at high heart rate (HR) and HR variability, as in patients with atrial fibrillation (AF), some concerns and small clinical experience characterize these subsets of challenging patients. However, patients with AF have been reported to have higher risk of cardiovascular events and noninvasive evaluation of suspected coronary artery disease in this setting may be of extreme clinical interest. The goal of this review is to provide to the reader an overview on the use of cardiac CT in patients with AF and high HR and to outline the technological improvements recently introduced in the clinical field that may enable to definitively overcome the limitations of cardiac CT in this challenging scenario.

Patient-Centered and Specialty-Specific Case Work-Up: An Effective Method for Teaching Appropriateness of Imaging to Medical Students.

Acad Radiol 2019 Feb 5. Epub 2019 Feb 5.

Department of Radiology, University of Pennsylvania, Philadelphia, Pennsylvania. Electronic address:

Rationale And Objectives: Our institution has developed a mini-course program within the diagnostic radiology elective curriculum that promotes active learning, using patient cases specifically tailored to students' future specialties. The purpose of this study is to evaluate the effectiveness of this mini-course on medical student knowledge of imaging appropriateness and attitude toward radiologist consultation.

Materials And Methods: During each month-long radiology elective course, students were divided into teams of up to four students based on their specialty interest and assigned recent patient cases with imaging findings relevant to their specialties. Read More

Recruiting Medical Students to Interventional Radiology: Current State of Affairs.

Acad Radiol 2019 Feb 4. Epub 2019 Feb 4.

Assistant Clinical Professor of Radiology University of California Los Angeles.

Objective: Interventional radiology/diagnostic radiology (IR/DR) is the newest primary specialties offered to trainees, one that medical students can now apply to directly out of medical school. However, medical students are disadvantaged in that the integrated IR/DR pathway requires early decision when often radiology rotations are not part of the core clerkship curriculum. Based upon results from a survey to Integrated IR/DR Program Directors, we report strategies being used by programs to introduce and attract medical students to IR. Read More

Practical Presentation Pearls: Evidence-based Recommendations From the Psychology and Physiology Literature.

Acad Radiol 2019 Jan 9;26(1):93-100. Epub 2018 Aug 9.

Department of Radiology, Penn State Health Milton S. Hershey Medical Center, Hershey, Pennsylvania.

Oral presentations remain a common teaching method in academic radiology. The goal of these presentations is to transfer knowledge from the presenter's brain to brains in the audience in a way that sticks. A number of studies from the recent psychological and physiological literature offer some rather practical and evidence-based advice on ways to optimize our oral presentations. Read More
