The Accomplishments and Legacy of Saul Hertz, MD.

The early history of the use of radioactive iodine (RAI) is complicated and interesting, and also difficult to discover, especially since several histories have presented inaccurate content. This article is a comprehensive review of the accomplishments of Saul Hertz. Extensive use of primary-source verification has clarified several issues, including the question of whether Hertz alone conceived and asked the pivotal question: "Could iodine be made radioactive artificially?"; on what date RAI was first used to treat hyperthyroidism; and why 2 articles on the first use of RAI for treatment of hyperthyroidism, from 2 different sets of authors from the same department of the same institution, appeared adjacent to each other in the same issue of the in 1946.

A Joint Statement from the American Thyroid Association, the European Association of Nuclear Medicine, the European Thyroid Association, the Society of Nuclear Medicine and Molecular Imaging on Current Diagnostic and Theranostic Approaches in the Management of Thyroid Cancer.

The American Thyroid Association (ATA), the European Association of Nuclear Medicine, the European Thyroid Association, and the Society of Nuclear Medicine and Molecular Imaging have established an intersocietal working group to address the current controversies and evolving concepts in thyroid cancer management and therapy. The working group annually identifies topics that may significantly impact clinical practice and publishes expert opinion articles reflecting intersocietal collaboration, consensus, and suggestions for further research to address these important management issues. In 2019, the intersocietal working group identified the following topics for review and interdisciplinary discussion: (i) perioperative risk stratification, (ii) the role of diagnostic radioactive iodine (RAI) imaging in initial staging, and (iii) indicators of response to RAI therapy.

A Critical Assessment of the Linear No-Threshold Hypothesis: Its Validity and Applicability for Use in Risk Assessment and Radiation Protection.

The Society of Nuclear Medicine and Molecular Imaging convened a task group to examine the evidence for the risk of carcinogenesis from low-dose radiation exposure and to assess evidence in the scientific literature related to the overall validity of the linear no-threshold (LNT) hypothesis and its applicability for use in risk assessment and radiation protection. In the low-dose and dose-rate region, the group concluded that the LNT hypothesis is invalid as it is not supported by the available scientific evidence and, instead, is actually refuted by published epidemiology and radiation biology. The task group concluded that the evidence does not support the use of LNT either for risk assessment or radiation protection in the low-dose and dose-rate region.

Controversies, Consensus, and Collaboration in the Use of I Therapy in Differentiated Thyroid Cancer: A Joint Statement from the American Thyroid Association, the European Association of Nuclear Medicine, the Society of Nuclear Medicine and Molecular Imaging, and the European Thyroid Association.

Background: Publication of the 2015 American Thyroid Association (ATA) management guidelines for adult patients with thyroid nodules and differentiated thyroid cancer was met with disagreement by the extended nuclear medicine community with regard to some of the recommendations related to the diagnostic and therapeutic use of radioiodine (I). Because of these concerns, the European Association of Nuclear Medicine and the Society of Nuclear Medicine and Molecular Imaging declined to endorse the ATA guidelines. As a result of these differences in opinion, patients and clinicians risk receiving conflicting advice with regard to several key thyroid cancer management issues.

Management of Diabetes Mellitus Before F-Fluorodeoxyglucose PET/CT: A Nationwide Patient-Centered Assessment of Approaches to Examination Preparation.

Purpose: The aim of this study was to perform, from the patient's point of view, a nationwide assessment of nuclear medicine practices regarding diabetic management before F-fluorodeoxyglucose (FDG) PET/CT for oncologic indications.

Methods: This prospective observational study was exempt from institutional review board oversight. Sixty-five nuclear medicine scheduling lines (33 academic, 32 private practice, 12-17 in each of the five US regions) were called using a prewritten script under the guise of a nonexpert patient's family member about scheduling a patient with diabetes with "cancer" for FDG PET/CT.

ACR Appropriateness Criteria Shoulder Pain-Traumatic.

Traumatic shoulder pain is pain directly attributed to a traumatic event, either acute or chronic. This pain may be the result of either fracture (the clavicle, scapula, or proximal humerus) or soft-tissue injury (most commonly of the rotator cuff, acromioclavicular ligaments, or labroligamentous complex). Imaging assessment of traumatic shoulder pain begins with conventional radiography and, depending on physical examination findings, will require MRI or MR arthrography for assessment of soft-tissue injuries and CT for delineation of fracture planes.
