ACR Appropriateness Criteria® on Metastatic Bone Disease

Appropriate imaging modalities for screening, staging, and surveillance of patients with suspected and documented metastatic disease to bone include (99m)Tc bone scanning, MRI, CT, radiography, and 2-[(18)F]fluoro-2-deoxyglucose-PET. Clinical scenarios reviewed include asymptomatic stage 1 breast carcinoma, symptomatic stage 2 breast carcinoma, abnormal bone scan results with breast carcinoma, pathologic fracture with known metastatic breast carcinoma, asymptomatic well-differentiated and poorly differentiated prostate carcinoma, vertebral fracture with history of malignancy, non-small-cell lung carcinoma staging, symptomatic multiple myeloma, osteosarcoma staging and surveillance, and suspected bone metastasis in a pregnant patient. No single imaging modality is consistently best for the assessment of metastatic bone disease across all tumor types and clinical situations. In some cases, no imaging is indicated. The recommendations contained herein are the result of evidence-based consensus by the ACR Appropriateness Criteria((R)) Expert Panel on Musculoskeletal Radiology.

RADPEER Peer Review: Relevance, Use, Concerns, Challenges, and Direction Forward

RADPEER is a product developed by the ACR that aims to assist radiologists with quality assessment and improvement through peer review. The program opened in 2002, was initially offered to physician groups in 2003, developed an electronic version in 2005 (eRADPEER), revised the scoring system in 2009, and first surveyed the RADPEER membership in 2010. In 2012, a survey was sent to 16,000 ACR member radiologists, both users and nonusers of RADPEER, with the goal of understanding how to make RADPEER more relevant to its members. A total of 31 questions were used, some of which were repeated from the 2010 survey. The ACRs RADPEER committee has published 3 papers on the program since its inception. In this report, the authors summarize the survey results and suggest future opportunities for making RADPEER more useful to its membership.

ACR Appropriateness Criteria® on Acute Shoulder Pain

The shoulder joint is a complex array of muscles, tendons, and capsuloligamentous structures that has the greatest freedom of motion of any joint in the body. Acute (<2 weeks) shoulder pain can be attributable to structures related to the glenohumeral articulation and joint capsule, rotator cuff, acromioclavicular joint, and scapula. The foundation for investigation of acute shoulder pain is radiography. Magnetic resonance imaging is the procedure of choice for the evaluation of occult fractures and the shoulder soft tissues. Ultrasound, with appropriate local expertise, is an excellent evaluation of the rotator cuff, long head of the biceps tendon, and interventional procedures. Fluoroscopy is an excellent modality to guide interventional procedures. Computed tomography is an excellent modality for characterizing complex shoulder fractures. Computed tomographic arthrography or fluoroscopic arthrography may be alternatives in patients for whom MR arthrography is contraindicated. A multimodal approach may be required to accurately assess shoulder pathology. The ACR Appropriateness Criteria(®) are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

ACR Appropriateness Criteria Acute Hip Pain—Suspected Fracture

Substantial cost, morbidity, and mortality are associated with acute proximal femoral fracture and may be reduced through an optimized diagnostic imaging workup. Radiography represents the primary diagnostic test of choice for the evaluation of acute hip pain. In middle aged and elderly patients with negative radiographs, the evidence indicates MRI to be the next diagnostic imaging study to exclude a proximal femoral fracture. CT, because of its relative decreased sensitivity, is only indicated in patients with MRI contraindications. Bone densitometry (DXA) should be obtained in patients with fragility fractures. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

Bedside Ultrasound Can Predict Nonalcoholic Fatty Liver Disease in the Hands of Clinicians Using a Prototype Image

This study was designed to test whether ultrasound can be used to diagnose nonalcoholic fatty liver disease (NAFLD) utilizing a prototype. We collected 115 ultrasounds. A prototype was chosen that represented NAFLD; 5 features of NAFLD prototype were described. Ultrasounds were read blinded to diagnosis as matching prototype or not. A 20-minute teaching session was made to a group of 15 providers. Ten ultrasounds were presented for comparison to prototype with intraobserver reliability measured. Of 20 patients shown by liver biopsy to have NAFLD, 16 were successfully predicted by comparison to the prototype (sensitivity 80%). In 94 of 95 cases, ultrasound predicted those without NAFLD (specificity 99%). The positive predictive value was 94% and negative predictive value 96%. Training results showed substantial agreement with a kappa score of 0.76 with 95% of cases identified correctly. In conclusion, physicians can apply a bedside ultrasound to identify NAFLD when compared to prototype.

Anaplastic Thyroid Carcinoma in a Young Woman: A Rare Case of Survival

BACKGROUND Anaplastic thyroid carcinoma (ATC) is rare but one of the most aggressive human cancers. It carries a dismal prognosis with average survival of 6 months. It is characteristically diagnosed in patients older than 60 years. We report the case of a young patient with ATC, in whom disease-free survival exceeds 2 years, and review the related literature. SUMMARY A 26-year-old woman presented with a rapidly growing anterior neck mass. A neck computed tomography scan showed a 3.5-cm left thyroid mass extending into the lateral neck. Fine-needle aspiration biopsy showed a malignant tumor. A subsequent core biopsy showed an undifferentiated epithelial carcinoma. A total thyroidectomy and left modified radical neck dissection were performed. Histopathology and immunohistochemical analysis confirmed an ATC. Postoperatively, the patient received radiation with concurrent chemotherapy. Serial follow-up imaging studies showed no evidence of residual or recurrent disease or metastases, and patient remains alive, free of disease, over 2 years. CONCLUSION ATC is usually a disease of the elderly but should be considered in the differential diagnosis of any patient who presents with a rapidly enlarging anterior neck mass. A rapid and thorough investigation should be initiated. This unusual case highlights that this aggressive thyroid cancer may occur in the young. It also emphasizes the role of aggressive surgery, if resectable.

Mandatory Assignment of Modified Wells Score Before CT Angiography for Pulmonary Embolism Fails to Improve Utilization or Percentage of Positive Cases.

OBJECTIVE The objective of our study was to determine the impact of embedding a pretest probability rule that is required during the computerized physician order-entry (CPOE) process on the appropriateness of CT angiography (CTA) of the pulmonary arteries for the diagnosis of pulmonary embolism (PE) in the emergency department (ED). MATERIALS AND METHODS Data were obtained from the electronic medical records of all adults who visited the ED from October 17, 2010, through October 17, 2012 (n = 96,507). The primary outcome was the appropriateness of pulmonary CTA. Logistic regression was used to test whether rates of appropriate use, overuse, and underuse of pulmonary CTA improved significantly after the implementation of the decision support tool when controlling for other patient characteristics. RESULTS Pulmonary CTA was appropriately used in 67.2% of patients with a modified Wells score of ≥ 4, a positive d-dimer test result, or both. CTA was overused in 19.3% of patients and underused in 13.5% of patients. Each additional month after the start of the intervention was associated with a 4-percentage point increase in the odds that the modified Wells score would indicate CTA had been used appropriately (odds ratio [OR] = 1.04; 95% CI, 1.01-1.07) and significantly lowered the odds of overuse of CTA (OR = 0.93; 95% CI, 0.90-0.96) based on the modified Wells score. These changes were not associated with any significant alteration in the level of CTA utilization or the positivity rate. CONCLUSION The addition of a mandatory field in the CPOE record was associated with a significant improvement in the appropriate ordering of pulmonary CTA but did not change the PE positive rate or CTA utilization. It seems likely that physicians gradually inflated the modified Wells scores in spite of the fact that a threshold modified Wells score was not required to perform pulmonary CTA.

Online Portals: Gateway to Patient-Centered Radiology

OBJECTIVE Online portals typically allow access to radiology reports, causing a shift in the communication. This article evaluates the studies available in the literature about patient portals and the use of patient portals in radiology. Patient and physician preferences and the impact on radiology reporting are presented. CONCLUSION Patient portals provide an opportunity for radiologists to engage with their patients via a new method of communication. Radiologist collaboration with referring physicians is important in providing care in accordance with patient preferences.

Advanced Practice Quality Improvement: Beyond the Radiology Department

Substantial opportunity exists for radiologists to lead practice quality improvement initiatives that extend beyond the boundaries of the radiology department, especially regarding the appropriate, evidence-based utilization of radiological services by clinical colleagues. Radiologists are uniquely positioned to lead these types of interdisciplinary quality projects. An example of one such project is reviewed, with a reflection on lessons learned; specific, practical recommendations derived from past efforts are made.
