Picture Archiving and Communication System (PACS) Implementation, Integration & Benefits in an Integrated Health System

The availability of the Picture Archiving and Communication System (PACS) has revolutionized the practice of radiology in the past two decades and has shown to eventually increase productivity in radiology and medicine. PACS implementation and integration may bring along numerous unexpected issues, particularly in a large-scale enterprise. To achieve a successful PACS implementation, identifying the critical success and failure factors is essential. This article provides an overview of the process of implementing and integrating PACS in a comprehensive health system comprising an academic core hospital and numerous community hospitals. Important issues are addressed, touching all stages from planning to operation and training. The impact of an enterprise-wide radiology information system and PACS at the academic medical center (four specialty hospitals), in six additional community hospitals, and in all associated outpatient clinics as well as the implications on the productivity and efficiency of the entire enterprise are presented.

Utilization of Dashboard Technology in Academic Radiology Departments: Results of a National Survey

PURPOSE The aim of this study was to identify the most widely used financial, productivity, and accessibility metrics used by academic radiology departments (ARDs) in a dashboard format via a national survey. The results provide a guide to the selection of preferred or commonly used indicators to facilitate dashboard implementation and use. METHODS The study met the criteria for an exemption from institutional review board approval. A cross-sectional survey was conducted using a survey approved by the Society of Chairs of Academic Radiology Departments and sent to its members. The survey was designed to evaluate the adoption, access, and composition of dashboard technology in ARDs, particularly those related to measures of productivity and financial performance. RESULTS The overall response rate was 42% (56 of 131 members). Sixty-two percent of responding ARDs currently use some form of dashboard technology, but 50% have used this technology for ≤2 years. Sixty-five percent of all ARDs use their dashboard information on a monthly basis. The two dashboard financial indicators most frequently used by ARDs are revenue and actual expenses. Similarly, the two productivity indicators used most widely are total examination volume and examination volume per modality. The two most important access indicators used are report turnaround time and backlog per unit time. CONCLUSIONS Currently, fewer than two-thirds of the responding ARDs use dashboard technology, and one-half have used the technology for ≤2 years. Although some fiscal and productivity indices are more frequently used, there are a diverse number of factors used to measure productivity, finance, access, and other operational parameters in ARD dashboards. Thus, the information provided by each institutional dashboard may be significantly different from that in other ARDs.

PET/MRI: Applications in Clinical Imaging

PET/MRI is a new hybrid modality which is increasingly being used in clinical settings, although both clinical evaluation and technical optimization are still an ongoing process. Initial experience with this new imaging device proves promising for oncologic applications. Other clinical indications in the field of cardiac imaging and neuroimaging are also being explored. This article aims to review the current status of PET/MRI and its value in oncologic applications, and summarizes our own preliminary experience in this field.

Magnetic Resonance/Positron Emission Tomography (MR/PET) Oncologic Applications: Bone and Soft Tissue Sarcoma

Introduction Bone and soft tissue sarcomas are rare and heterogeneous tumor entities; more than 50 histologic subtypes of these exist. Soft tissue sarcomas account for 0.7% and 6.5% of all adult and childhood malignancies, respectively, and primary bone cancer comprises 0.2% of all malignancies. Established treatment protocols for sarcoma are multimodal and complex and include surgery, neoadjuvant chemotherapy, adjuvant chemotherapy, and radiation therapy. Most recently, targeted therapy has been introduced in the clinical setting and is being tested in a variety of trials. Metastatic disease occurs in up to 60% of patients with sarcoma who have been treated initially with curative intention, and the lung is the most common site of metastasis in most histologic subtypes of sarcoma. Improved outcomes may be attainable with earlier detection of metastatic disease and with accurate detection of local recurrence following therapy.

Design and implementation of disaster recovery and business continuity solution for radiology PACS

In the digital era of radiology, picture archiving and communication system (PACS) has a pivotal role in retrieving and storing the images. Integration of PACS with all the health care information systems e.g., health information system, radiology information system, and electronic medical record has greatly improved access to patient data at anytime and anywhere throughout the entire enterprise. In such an integrated setting, seamless operation depends critically on maintaining data integrity and continuous access for all. Any failure in hardware or software could interrupt the workflow or data and consequently, would risk serious impact to patient care. Thus, any large-scale PACS now have an indispensable requirement to include deployment of a disaster recovery plan to ensure secure sources of data. This paper presents our experience with designing and implementing a disaster recovery and business continuity plan. The selected architecture with two servers in each site (local and disaster recovery (DR) site) provides four different scenarios to continue running and maintain end user service. The implemented DR at University Hospitals Health System now permits continuous access to the PACS application and its contained images for radiologists, other clinicians, and patients alike.

Impact of Patient Protection and Affordable Care Act on Academic Radiology Departments' Clinical, Research, and Education Missions

The Patient Protection and Affordable Care Act (ACA) generated significant media attention since its inception. When the law was approved in 2010, the U.S. health care system began facing multiple changes to adapt and to incorporate measures to meet the new requirements. These mandatory changes will be challenging for academic radiology departments (ARDs) since they will need to promote a shift from a volume-focused to a value-focused practice. This will affect all components of the mission of ARDs, including clinical practice, education, and research. A unique key element to success in this transition is to focus on both quality and safety, thus improving the value of radiology in the post-ACA era. Given the changes ARDs will face during the implementation of ACA, suggestions are provided on how to adapt ARDs to this new environment.

Advantages of time-resolved contrast-enhanced 4D MR angiography in splenic arterial steal syndrome

Splenic artery steal syndrome (SASS) is a severe complication affecting up to 10% of orthotopic liver transplant (OLT) patients. In this case report, we present a 35-year-old male with OLT secondary to liver failure due to hemochromatosis, who developed SASS. We describe potential application of different imaging techniques for diagnosis of SASS with focus on the value of time-resolved contrast enhanced 4D magnetic resonance angiography (MRA).
