    ABSTRACT: Total knee replacement (total knee arthroplasty) is performed to restore function and relieve pain in patients with severely damaged knees. The surgery involves replacement of both the medial and lateral femorotibial joints and the patellofemoral joint. Although total knee replacement is an effective treatment, postoperative complications include blood clots, infection, and loosening or malalignment of the prosthetic component. Medical imaging plays a critical role in preoperative evaluation, surgical planning, and followup.

    ABSTRACT: This article presents the anatomy of the chest, heart, and upper airway and describes types of traumatic pathology and injuries of the chest. Chest imaging in a variety of settings is described. Radiography, computed tomography, and ultrasonography are discussed, along with the benefits and limitations of each modality. Finally, promising technological developments that could aid chest imaging in emergent situations are reviewed.

    ABSTRACT: Purpose: To evaluate the self-reported leadership practices of radiology administrators and the demographic characteristics associated with those leadership practices. The effect of these demographic characteristics and leadership practices on job satisfaction also was studied. Methods: One-hundred forty-nine American Society of Radiologic Technologists members who indicated they have a position of administrator/manager, chief technologist, or supervisor completed a demographic survey and the Leadership Practices Inventory (LPI) self-survey tool. The LPI divides successful leadership into 5 practices: Challenge the Process, Inspire a Shared Vision, Enable Others to Act, Encourage the Heart, and Model the Way. Results: The categories Challenge the Process and Inspire a Shared Vision had the lowest mean scores and the widest variation. Having had formal leadership training and being older were demographic characteristics associated with higher LPI scores. Having a higher LPI score and having had formal leadership training were associated with higher job satisfaction. Discussion: Formal leadership training was the only statisically significant variable when using LPI score as the response variable. Conclusion: The results of this study show that radiology administrators would benefit from formal leadership training that focuses on challenging the process and inspiring a shared vision.

    ABSTRACT: Background: Femoroacetabular impingement (FAI) is commonly seen in young or middle-aged patients. Early detection and correction of FAI-related bony deformities or pelvic realignment are essential to prevent the development or progression of hip osteoarthritis. Discussion: Computed tomography (CT) and magnetic resonance (MR) imaging are the reference standards for the evaluation of bony anatomy and treatable internal derangement findings of the hip, respectively. Surgeons prefer CT imaging for preoperative bone delineation because of its 3-D isotropic capabilities and excellent multiplanar reconstructions. Three-Tesla (3T) MR scans enable high-resolution 3-D MR reconstructions for bone depiction similar to 3-D CT reconstructions and have the potential to eliminate the need for duplicate (CT and MR) scanning. Conclusion: This technical report illustrates the feasibility of such an approach and compares bone rendering obtained using isotropic data from 3-D MR with 3-D CT in the same patient.

    ABSTRACT: Artifacts appear on breast images for a number of reasons. Radiologic technologists play an important role in identifying artifacts that can help or hinder breast cancer diagnosis and in minimizing artifacts that degrade image quality. This article describes various artifacts that occur in breast imaging, along with their causes. The article focuses on artifacts in mammography, with a heavy emphasis on digital mammography, and on magnetic resonance imaging of the breast. Artifacts in ultrasonography of the breast, digital breast tomosynthesis, and positron emission mammography also are discussed.

    ABSTRACT: Purpose: To evaluate radiographers' ability to detect low-contrast detail using various digital planar radiographic systems. Methods: A low-contrast detail phantom was placed between two 5-cm thick Perspex sheets (Lucite International). Images were obtained using different kilovoltage peak and milliamperage second (mAs) settings with computed radiography (CR), indirect conversion digital radiography (IDR), and direct conversion digital radiography (DR) systems. Six groups of 6 radiographers were asked to score 39 images; each group scored 2 images from each system for a total of 6 images. The seventh group scored only one image from each system for a total of 3 images. The radiographers' results were compared with the results of analyzer software. The inverse image quality factor was used to measure low-contrast detail detectability performance. Results: Radiographers performed significantly worse than the computerized software in determining low-contrast detail in planar radiographic images (P < .01). However, a positive correlation (R = 0.558) existed between the 2 sets of scores in terms of low-contrast detail detectability performance. Discussion: On average, radiographers were able to detect increased image quality resulting from increased mAs. Radiographers reached results similar to the software regarding whether IDR and DR have better detectability performances than CR. Differences found among individual radiographers were not as significant with DR. Conclusion: When radiographers' performance in detecting low-contrast detail was evaluated and compared with that of the software, radiographers exhibited poorer performances. Because radiographers are responsible for image quality optimization, additional training might improve their ability to detect low-contrast detail in DR systems.

    ABSTRACT: Interventional ablative technologies aided by imaging techniques such as ultrasonography, computed tomography, and magnetic resonance imaging have been crucial in managing patients with primary liver cancer and liver metastases over the past 20 years. Several ablative technologies have been used to treat liver cancer; however, radiofrequency ablation (RFA) has emerged as the most common ablative therapy for hepatic lesions, both in the United States and globally. RFA is the treatment of choice for patients who cannot have surgical resection of the liver. This article focuses on the role of imaging in RFA treatment of primary and metastatic hepatic lesions.

    ABSTRACT: Pancreatic disease often is asymptomatic until tissue damage and complications occur or until malignancies have reached advanced stages and have metastasized. Contrast-enhanced multidetector computed tomography plays a central role in diagnosing, staging, and treatment planning for pancreatitis and pancreatic cancer. This article introduces the functional anatomy of the pancreas and common bile duct and the epidemiology, pathobiology, and computed tomography imaging of pancreatitis, calculi, and pancreatic cancer.
