BACKGROUND:and diffusion-weighted imaging (DWI) can be utilized as a screening exam. PURPOSE/OBJECTIVE:To review the accuracy and feasibility of an interdisciplinary prospective contrast-enhanced MRI pelvis with DWI screening system for LMS prior to fibroid resection. STUDY TYPE/METHODS:Retrospective cohort study. POPULATION/METHODS:In all, 1960 adult female patients aged 18-87 undergoing screening MRI pelvis prior to uterine fibroid resection. FIELD STRENGTH/SEQUENCE/UNASSIGNED:-weighted imaging, DWI, and contrast-enhanced images were acquired at 1.5 T and 3.0 T. ASSESSMENT/RESULTS:signal intensity, irregular margins, hemorrhage, and necrosis. A preliminary cost-effectiveness analysis was performed, comparing the costs of treatment of uterine fibroids with vs. without a collaborative screening protocol using MRI. STATISTICAL TESTS/UNASSIGNED:Sensitivity, specificity, positive predictive value, and negative predictive value were obtained from the prospective evaluations. Student's t-tests were used to compare demographics and apparent diffusion coefficient values between LMS and false-positive results. RESULTS:We prospectively identified LMS patients with 100% sensitivity and 97% specificity. Preliminary cost analysis demonstrated that the MR screening protocol increased life expectancy by 0.04 years at a cost of $12,937 per life-year gained. DATA CONCLUSION/UNASSIGNED:MRI is an effective and potentially economic screening test, especially with standardized reporting and coordination with clinicians.

Funding for research has become increasingly difficult to obtain in an environment of decreasing clinical revenue, increasing research costs, and growing competition for federal and nonfederal funding sources. This paper identifies critical requirements to build and sustain a successful radiology research program (eg, key personnel and leadership, research training and mentorship, infrastructure, institutional and departmental funding or support), reviews the current state of available funding for radiology (including federal, nonfederal, philanthropy, crowdfunding, and industry), and describes promising opportunities for future funding (eg, health services, comparative effectiveness, and patient-centered outcomes research). The funding climate, especially at the federal level, changes periodically, so it is important to have radiology-specific organizations such as the American College of Radiology and the Academy of Radiology Research serving as our key advocates. Key to obtaining any funding, no matter what the source, is a well-formulated grant proposal, so a review of opportunities specifically available to radiologists to develop and hone their grant-writing skills is provided. Effective and sustained funding for radiology research has the potential to cultivate young researchers, bolster quality research, and enhance health care. Those interested in pursuing research need to be aware of the ever-changing funding landscape, research priority areas, and the resources available to them to succeed. To succeed, radiology researchers need to think about diversification and flexibility in their interests, developing multidisciplinary and multi-institutional projects, and engaging a broader base of stakeholders that includes patients.

A 61-year-old Asian man presented with severe right upper quadrant pain which had been worsening for several months. Laboratory results indicated elevated aspartate aminotransferase and alanine aminotransferase. The subsequent ultrasound, CT and MRI showed a large cystic mass with solid components and severe intrahepatic and extrahepatic biliary ductal dilatation. The mass was resected and pathology showed a well-demarcated mucinous cystic lesion with polygonal cells containing ovoid nuclei and abundant pink oncocytic cytoplasm. These findings are characteristic of intraductal oncocytic papillary neoplasm (IOPN), a rare subtype of intraductal papillary neoplasm of the liver. IOPN occurs most frequently in the Asian regions endemic to clonorchiasis and hepatolithiasis; however, cases have been reported in the Western world as well. Patients with IOPN are male or female and typically middle-aged. Treatment is typically resection. Prognosis is favourable and recurrence is rare. The 5-year survival rate is upwards of 80%.

Editor's Note.-RadioGraphics continues to publish radiologic-pathologic case material selected from the American Institute for Radiologic Pathology (AIRP) "best case" presentations. The AIRP conducts a 4-week Radiologic Pathology Correlation Course, which is offered five times per year. On the penultimate day of the course, the best case presentation is held at the American Film Institute Silver Theater and Cultural Center in Silver Spring, Md. The AIRP faculty identifies the best cases, from each organ system, brought by the resident attendees. One or more of the best cases from each of the five courses are then solicited for publication in RadioGraphics. These cases emphasize the importance of radiologic-pathologic correlation in the imaging evaluation and diagnosis of diseases encountered at the institute and its predecessor, the Armed Forces Institute of Pathology (AFIP).
