RESUMO
This section focuses on the professional workforce comprised of the primary medical specialties that utilize ionizing radiation in their practices. Those discussed include the specialties of radiology and radiation oncology, as well as the subspecialties of radiology, namely diagnostic radiology, interventional radiology, nuclear radiology, and nuclear medicine. These professionals provide essential health care services, for example, the interpretation of imaging studies, the provision of interventional procedures, radionuclide therapeutic treatments, and radiation therapy. In addition, they may be called on to function as part of a radiologic emergency response team to care for potentially exposed persons following radiation events, for example, detonation of a nuclear weapon, nuclear power plant accidents, and transportation incidents. For these reasons, maintenance of an adequate workforce in each of these professions is essential to meeting the nation's future needs. Currently, there is a shortage for all physicians in the medical radiology workforce.

Existing surveys of radiopharmaceutical doses for U.S. nuclear medicine laboratories are of limited scope and size. Dose data are important because they can be used to benchmark individual laboratories, understand geographic variations in practice, and provide source data for societal guidelines and appropriateness criteria. Diagnostic reference levels (DRLs) and achievable administered activities (AAAs) for 13 noncardiac adult gamma camera and PET/CT examinations were derived retrospectively from American College of Radiology accreditation data (January 1, 2015, to December 31, 2017). The calculated DRL and AAA are consistent with previously published surveys. The distributions of radiopharmaceutical doses across facilities are in general consistent but show variation within a particular examination. Analysis of dose distribution suggests this variation results from differences in clinical protocols, educational gaps, and/or equipment factors. The AAA for the surveyed facilities exceeds dose ranges proposed in societal practice guidelines for several common nuclear medicine studies. Compared with similar surveys from Europe and Japan, geographic variation is observed, with some doses greater and others lower than used in the United States. Overall, radiopharmaceutical dose variation within the United States and internationally, and deviation from societal guidelines, imply that these dose-related benchmarks may be used to further standardize and improve clinical practice.

Women are, and have always been, underrepresented in radiology. This gender disparity must be addressed. Women bring a different perspective to the workplace; and their collaborative, empathetic, and compassionate approach to patient care and education is an asset that the radiology community should embrace and leverage. Radiologic organizations should focus on removing barriers to the entry of women physicians into radiology as a specialty and to their career advancement. Organizations should address bias, promote physician well-being, and cultivate a safe and positive work environment. Radiology leaders committed to increasing gender diversity and fostering an inclusive workplace have the opportunity to strengthen their organizations. This article outlines the key steps that practice leaders can take to address the needs of women in radiology: (a) marketing radiology to talented women medical students, (b) addressing recruitment and bias, (c) understanding and accommodating the provisions of the Family and Medical Leave Act of 1993 and the Fair Labor Standards Act for both trainees and radiologists in practice, (d) preventing burnout and promoting well-being, (e) offering flexible work opportunities, (f) providing mentorship and career advancement opportunities, and (g) ensuring equity. ©RSNA, 2018.

There are approximately 200 academic radiology departments in the United States. While academic medical centers vary widely depending on their size, complexity, medical school affiliation, research portfolio, and geographic location, they are united by their 3 core missions: patient care, education and training, and scholarship. Despite inherent differences, the current challenges faced by all academic radiology departments have common threads; potential solutions and future adaptations will need to be tailored and individualized-one size will not fit all. In this article, we provide an overview based on our experiences at 4 academic centers across the United States, from relatively small to very large size, and discuss creative and innovative ways to adapt, including community expansion, hybrid models of faculty in-person vs teleradiology (traditional vs non-traditional schedule), work-life integration, recruitment and retention, mentorship, among others.

OBJECTIVE: During the 20th century, radiologists enjoyed relationships with clinicians and patients through daily face-to-face communication. As specialist consultants, radiologists were naturally integral members of the care team. CONCLUSION: The widespread availability of information technology, notably PACS, has disrupted the fundamental radiologist-clinician axis. New generations of radiologists must respond to this disturbing trend by (re)learning how to "add value" by rekindling personal professional relationships, developing global leadership skills, and becoming involved in health care system design and implementation.

Despite widespread interest in creating a more equitable and inclusive culture, a lack of workforce diversity persists in Radiology, in part due to a lack of universal and longitudinal metrics across institutions. In an attempt to establish benchmarks, a subset of the Society of Chairs of Academic Radiology Departments (SCARD) Diversity, Equity and Inclusion (DEI) Committee volunteered to design a DEI dashboard as a potential tool for academic radiology programs to use to document and track their progress. This freely-available, modular dashboard includes suggested (plus optional department-defined) DEI activities/parameters and suggested assessment criteria across three domains: faculty, residents & fellows, and medical students; it can be completed, in whole or in part, by departmental leaders annually. The suggested metrics and their associated rubrics were derived from the collective experiences of the five working group members, all of whom are chairs of academic radiology departments. The resulting dashboard was unanimously approved by the remaining 14 DEI committee members and endorsed by the SCARD board of directors.

ABSTRACT: Many parenteral radiopharmaceuticals available as anticancer therapy are filtered by the kidneys and excreted in the urine. Here, physician leaders of radiation medicine, nuclear medicine/molecular imaging, and the radiotheranostics programs as well as radiation safety officers, collaborated to develop a decision-making guideline for the administration of therapeutic radiopharmaceuticals in patients with pretherapy or day-of-treatment incontinence. We discussed challenges and opportunities in the screening of patients in urine collection strategies according to grade of urinary incontinence and in subsequent coordination of care. Lutetium-177 ( 177 Lu)-based radiopharmaceutical therapies provided clinical examples of how our procedures were operationalized. Our key management issues of urinary incontinence were cutaneous radiation injury and redness, infection, or pain. In response, we developed clinical practice guidelines for the recognition and management of incontinence-related adverse events. Common adverse events of urinary incontinence were noted in this study. Our how-to guideline for the safe administration of therapeutic radiopharmaceuticals for patients with urinary incontinence warrants further investigation and should continue to be evaluated across all radiopharmaceutical therapy agents.

RATIONALE AND OBJECTIVES: Standardized Uptake Value (SUV) is an important semiquantitative measurement used in the clinical and research domains to assess radiopharmaceutical concentration in tumors versus normal organs, but is susceptible to many factors beyond the tumor biological environment. So, the aim of this study is to identify the optimum internal reference among organs with physiological uptake in 68Ga-DOTATATE PET/CT (DOTA PET/CT) scans. MATERIALS AND METHODS: This HIPAA-compliant, IRB-approved study with waiver of consent included retrospective imaging review of 180 consecutive patients with neuroendocrine tumors presenting for DOTA PET/CT image acquisition: Ga-68 DOTATATE dose was reported as (0.054 mCi/Kg) scans between September 2018 and May 2019. Mean value of body weight normalized SUV (SUVbw) and lean body mass normalized SUV (SUL) of liver and spleen were measured. Information about the patients and scan characteristics were collected. The paired Grambsch test was used to compare variance among the measured SUVs. Spearman's rank correlation coefficient was used to assess correlation between SUVs and potential patient- and scan-specific confounding factors. RESULTS: Variance of SUL was significantly lower than variance of SUVbw in both liver and spleen (p-value < 0.0001). Variances of liver SUVbw and SUL were significantly lower than the corresponding spleen SUVs. Liver SUL showed the lowest variance (3.69% ± 1.25%) among all measured SUVs. CONCLUSION: SUL is a more reproducible, less variable, and therefore more reliable quantitative measure in DOTA PET/CT scans, compared SUVbw. Among the available organs with physiological uptake, liver SUL is the optimum internal reference given the liver's larger size and uniform SUL values resulting in lower variability and better reproducibility.

Since 1927, the American College of Radiology (ACR) has awarded Gold Medals to up to four individuals each year in recognition of their distinguished and extraordinary service to the ACR or to the discipline of radiology (American College of Radiology, n.d. [1]). As of 2019, only 10 of 194 Gold Medalists have been women. In May 2021, Dr. Cheri L. Canon will become the eleventh woman in ACR history to receive this prestigious award. Contemporaneously, in November 2020, she received the highest honor bestowed by the American Association for Women in Radiology (AAWR), the Marie Sklodowska-Curie Award, presented annually to an individual who has made outstanding contributions to the advancement of women in radiology or radiation oncology (American Association for Women in Radiology, n.d. [2]). Herein we celebrate Dr. Canon's remarkable life and impressive career achievements, and learn important lessons from her shared wisdom.

BACKGROUND: Nuclear medicine (NM) is a multidisciplinary field. Its overlap with nuclear radiology (NR) creates unique training considerations, opportunities, and challenges. Various factors impact the workforce, training needs, and training pathways. This state of flux may be perplexing to prospective NM/NR trainees. PURPOSE: To evaluate the state of NM/NR training by assessing the (1) workforce trends and job prospects for NM/NR trainees, (2) NM and NR training pathways, and (3) applicant-accessible online presence of training programs. METHODS: Workforce trends were analyzed using data collected from the 2017 American College of Radiology Commission on Human Resources Workforce Survey. Information regarding the training pathways leading to board certification(s) for NM and NR physicians were obtained through the American Board of Nuclear Medicine, the American Board of Radiology (ABR), and the Society of Nuclear Medicine and Medical Imaging. Each Accreditation Council for Graduate Medical Education-accredited NM residency or NR fellowship training program's website was reviewed for 20 content items to assess its comprehensiveness for those seeking information regarding eligibility, applications, training curriculum, and program characteristics. RESULTS: Number of hires for NM/NR physicians has exceeded the projected number of hires from 2014 to 2017. In the last decade, there has been a greater than 25% decrease in the combined number of traditional NM residencies and NR fellowships (79-58 programs) and a greater than 50% decrease in the combined number of NM and NR trainees (173-82 trainees). In 2017, the ABR redesigned its 16-month pathway leading to specialty certification in diagnostic radiology and subspecialty certification in NR. As of March 24, 2019, there are 36 diagnostic radiology or IR residency programs with 64 trainees participating in this redesigned NR pathway. Of the 93.1% (54/58) of traditional Accreditation Council for Graduate Medical Education-accredited NM and NR training programs having websites in the 2017-2018 academic year, the mean number of online criteria met per program was 7.74 ± 3.2 of 20 (38.7%). CONCLUSION: Recruitment into the traditional NM/NR training pathways has been steadily declining, but there has been a renewed interest with the redesigned ABR 16-month pathway. There is a paucity of online information available to prospective NM/NR applicants. In this rapidly evolving and unique field, it is important to streamline NM/NR training and bolster the information accessible to potential NM/NR applicants as they weigh career options.

PURPOSE: To retrospectively compare pretherapy iodine 123 ((123)I) and posttherapy iodine 131 ((131)I) sodium iodide whole-body scintigraphy of patients with newly diagnosed differentiated thyroid cancer to determine if there is significant and clinically relevant discordance of nonphysiologic iodide-avid foci (IAFs) between the two examinations. MATERIALS AND METHODS: This study was approved by the Institutional Review Board, the requirement for informed consent was waived, and the study complied with HIPAA. The authors identified 108 patients (88 women, 20 men; age range, 16-86 years; mean, 47.5 years; 45 patients younger than 45 years, 63 patients 45 years and older) who previously had undergone total or near-total thyroidectomy for differentiated thyroid carcinoma. Each patient had undergone a pretherapy ( 123)I whole-body scan followed by a posttherapy ( 131)I whole-body scan. The number and location of IAFs were recorded on both scans. Data were compared by using a Wilcoxon signed rank test for paired data and assessed clinical relevance based on changes in tumor staging. RESULTS: Posttherapy ( 131)I whole-body scans revealed additional IAFs outside the thyroid bed not detected on pretherapy ( 123)I scans in 21 (19%, P < .001) of 108 patients. Nineteen (90%) of these 21 had IAFs in new locations (P < .001), with tumor upstaging of 11 (59%, 10% of total) of those 19 patients; six (55%, 6% of total) of those 11 had scintigraphic patterns consistent with unsuspected metastatic disease. Concordant scintigraphic patterns were observed in 87 (81%) of 108. CONCLUSION: In patients with newly diagnosed differentiated thyroid cancer who had undergone thyroidectomy and ( 131)I ablation, posttherapy ( 131)I whole-body scintigraphy revealed new IAFs in 18% and clinical upstaging occurred in 10% of patients compared with pretherapy ( 123)I whole-body scintigraphy. Therefore, posttherapy ( 131)I whole-body scintigraphy provides incremental clinically relevant information as it helps to establish the true extent of IAFs and may contribute to altering of staging.

A 25-y-old man with horseshoe kidney was referred for diuretic-augmented renal scintigraphy. Single-detector dynamic posterior imaging was performed and revealed asymmetric retention of radiotracer in the left collecting system. Renal scintigraphy was repeated with a modified protocol. Dynamic imaging was performed this time using dual-detector acquisition of both anterior and posterior data. Thereafter, pregravity and subsequently postgravity static images were obtained in both anterior and posterior projections. This second study showed near-complete emptying of the left collecting system. This case illustrates the utility of using simultaneous anterior and posterior imaging and geometric mean calculations for functional analysis and also highlights the value of physiologic maneuvers to augment the traditional diuretic challenge.

Despite increasing reliance on CT, MRI, and FDG PET/CT for oncological imaging, whole-body skeletal scintigraphy remains a frontline modality for staging and surveillance of osseous metastatic disease. We present a 54-year-old woman with metastatic breast cancer who received palliative external-beam radiation to the left ilium. Serial follow-up Tc-MDP bone scans demonstrated progressive soft-tissue uptake in her left lower extremity, extending from thigh to leg, with associated enlargement and skin thickening, consistent with lymphedema related to radiation-induced fibrosis. Correlative abdominopelvic CT scans confirmed fibrotic changes in the left thigh.

RATIONALE AND OBJECTIVES: The American Board of Radiology Core Examination integrates assessment of physics knowledge into its overall testing of clinical radiology, with an emphasis on understanding image quality and artifacts, radiation dose, and patient safety for each modality or subspecialty organ system. Accordingly, achieving a holistic approach to physics education of radiology residents is a huge challenge. The traditional teaching of radiological physics-simply through didactic lectures-was not designed for such a holistic approach. Admittedly, time constraints and clinical demands can make incorporation of physics teaching into clinical practice problematic. We created and implemented a week-long, intensive physics rotation for fledgling radiology residents and evaluated its effectiveness. MATERIALS AND METHODS: The dedicated physics rotation is held for 1 week during the first month of radiology residency. It comprises three components: introductory lectures, hands-on practical clinical physics operations, and observation of clinical image production. A brief introduction of the physics pertinent to each modality is given at the beginning of each session. Hands-on experimental demonstrations are emphasized, receiving the greatest allotment of time. The residents perform experiments such as measuring radiation dose, studying the relationship between patient dose and clinical practice (eg, fluoroscopy technique), investigating the influence of acquisition parameters (kV, mAs) on radiographs, and evaluating image quality using computed tomography, magnetic resonance imaging, ultrasound, and gamma camera/single-photon emission computed tomography/positron emission tomography phantoms. Quantitative assessment of the effectiveness of the rotation is based on an examination that tests the residents' grasp of basic medical physics concepts along with written course evaluations provided by each resident. RESULTS: The pre- and post-rotation tests show that after the physics rotation, the average correct score of 25 questions improved from 13.6 ± 2.4 to 19 ± 1.2. The survey shows that the physics rotation during the first week of residency is favored by all residents and that 1 week's duration is appropriate. All residents are of the opinion that the intensive workshop would benefit them in upcoming clinical rotations. Residents acknowledge becoming more comfortable regarding the use of radiation and providing counsel regarding radiation during pregnancy. CONCLUSIONS: An immersive, short-duration, clinically oriented physics rotation is well received by new or less experienced radiology trainees, correlates basic physics concepts with their relevance to clinical imaging, and more closely parallels expectations of the American Board of Radiology Core Examination.
