Cultivating Physician Character in Diagnostic Radiology Through Virtuous Caring and Collaborative Professionalism.

Acad Radiol 2018 May 25. Epub 2018 May 25.

Department of Radiology, University of Colorado School of Medicine, University of Colorado Anschutz Campus, Aurora, Colorado.

In the contemporary environment of patient- and value-centered care, it is no longer sufficient to limit the definition of an "excellent radiologist" to someone who is skilled at image interpretation. Since diagnostic radiologists are physicians, they are held to a certain character standard expected of a physician, whose primary objective is to serve the best interest of patients. An "excellent radiologist," then, is better defined as one who is both skilled at interpreting medical imaging and embodies the attributes of physician character. Read More

Impact of Immediate Interpretation of Screening Tomosynthesis Mammography on Performance Metrics.

Acad Radiol 2018 May 7. Epub 2018 May 7.

Radiology and Imaging Sciences, University of Utah/Huntsman Cancer Institute, 30 N 1900 E, Salt Lake City, UT 84132.

Rationale And Objectives: This study aimed to compare performance metrics for immediate and delayed batch interpretation of screening tomosynthesis mammograms.

Materials And Methods: This HIPAA compliant study was approved by institutional review board with a waiver of consent. A retrospective analysis of screening performance metrics for tomosynthesis mammograms interpreted in 2015 when mammograms were read immediately was compared to historical controls from 2013 to 2014 when mammograms were batch interpreted after the patient had departed.

The Visibility of the Terminal Thoracic Duct Into the Venous System Using MR Thoracic Ductography with Balanced Turbo Field Echo Sequence.

Acad Radiol 2018 May 7. Epub 2018 May 7.

Department of Diagnostic Radiology, Tokai University School of Medicine, 143 Shimokasuya, Isehara, 259-1193, Japan.

Rationale And Objectives: Magnetic resonance thoracic ductography (MRTD) with balanced turbo field echo (bTFE) can visualize both the thoracic duct and its surrounding vessels. This study aimed to investigate the visibility of the terminal thoracic duct into the venous system in the subclavian region using MRTD with bTFE.

Materials And Methods: MRTD was performed with bTFE as a preoperative workup comprising respiratory gating on a 1. Read More

Radiology Education in Medical School and Residency: The Views and Needs of Program Directors.

Acad Radiol 2018 May 7. Epub 2018 May 7.

Department of Radiology, University of Chicago, Chicago, Illinois.

Rationale And Objectives: The authors of this study used the perspectives of residency program directors (PDs) nationally to explore whether trainees are adequately prepared to utilize and interpret medical imaging as interns, to identify the types of imaging skills most important for residency, and to begin to address current shortcomings in radiology education.

Materials And Methods: The authors created a survey using a modified version of Accreditation Council for Graduate Medical Education radiology milestones and sent it to 100 randomly selected PDs each in pediatrics, internal medicine, obstetrics and gynecology, and general surgery. The survey asked PDs to assess the actual and desired imaging skills of their incoming interns, the incoming interns' variability of skill level upon matriculation, and which imaging skills were most important from the PDs' perspective.

Association of Focal Radiation Dose Adjusted on Cross Sections with Subsolid Nodule Visibility and Quantification on Computed Tomography Images Using AIDR 3D: Comparison Among Scanning at 84, 42, and 7 mAs.

Acad Radiol 2018 May 4. Epub 2018 May 4.

Department of Radiology, Shiga University of Medical Science, Seta-tsukinowa-cho, Otsu, Shiga, 520-2192, Japan.

Rationale And Objectives: The objectives of this study were to compare the visibility and quantification of subsolid nodules (SSNs) on computed tomography (CT) using adaptive iterative dose reduction using three-dimensional processing between 7 and 42 mAs and to assess the association of size-specific dose estimate (SSDE) with relative measured value change between 7 and 84 mAs (RMVC) and relative measured value change between 42 and 84 mAs (RMVC).

Materials And Methods: As a Japanese multicenter research project (Area-detector Computed Tomography for the Investigation of Thoracic Diseases [ACTIve] study), 50 subjects underwent chest CT with 120 kV, 0.35 second per location and three tube currents: 240 mA (84 mAs), 120 mA (42 mAs), and 20 mA (7 mAs).

Uncited Research Articles in Popular United States General Radiology Journals.

Acad Radiol 2018 May 3. Epub 2018 May 3.

Department of Radiology and Imaging Sciences, Emory University School of Medicine, Atlanta, Georgia.

Rationale And Objectives: This study aimed to characterize articles in popular general radiology journals that go uncited for a decade after publication.

Methods: Using the Web of Science database, we identified annual citation counts for 13,459 articles published in Radiology, American Journal of Roentgenology, and Academic Radiology between 1997 and 2006. From this article cohort, we then identified all original research articles that accrued zero citations within a decade of publication. Read More

Performance of T2 Maps in the Detection of Prostate Cancer.

Acad Radiol 2018 May 3. Epub 2018 May 3.

Department of Radiology, University of Chicago, 5841 South Maryland Avenue, Chicago, IL 60637. Electronic address:

Rationale And Objectives: This study compares the performance of T2 maps in the detection of prostate cancer (PCa) in comparison to T2-weighted (T2W) magnetic resonance images.

Materials And Methods: The prospective study was institutional review board approved. Consenting patients (n = 45) with histologic confirmed PCa underwent preoperative 3-T magnetic resonance imaging with or without endorectal coil. Read More

Is There a Direct Correlation Between Microvascular Wall Structure and k-Trans Values Obtained From Perfusion CT Measurements in Lymphomas?

Acad Radiol 2018 May 3. Epub 2018 May 3.

Department of Diagnostic and Interventional Radiology, University Hospital Ulm, Albert-Einstein-Allee 23, 89081 Ulm, Germany. Electronic address:

Rationale And Objectives: This study aimed to test the hypothesis that ultrastructural wall abnormalities of lymphoma vessels correlate with perfusion computed tomography (PCT) kinetics.

Materials And Methods: Our local institutional review board approved this prospective study. Between February 2013 and June 2016, we included 23 consecutive subjects with newly diagnosed lymphoma, who were referred for computed tomography-guided biopsy (6 women, 17 men; mean age, 60. Read More

Cultivating Future Radiology Educators: Development and Implementation of a Clinician-Educator Track for Residents.

Acad Radiol 2018 May 3. Epub 2018 May 3.

Department of Radiology and Imaging Sciences, Emory University School of Medicine, 1364 Clifton Rd. NE, D125A, Atlanta, GA 30322.

Effective and dedicated educators are critical to the preservation and advancement of the practice of radiology. The need for innovative and adaptable educators is increasingly being recognized, with several institutions granting academic promotions through clinician-educator tracks. The implementation of resident "clinician-educator tracks" or "teaching tracks" should better prepare residents aspiring to become academic radiologists focused on teaching. Read More
