OBJECTIVE. The purpose of this investigation was to assess workflow for medical imaging studies, specifically comparing liver and knee MRI examinations by use of the Lean Six Sigma methodologic framework. The hypothesis tested was that the Lean Six Sigma framework can be used to quantify MRI workflow and to identify sources of inefficiency to target for sequ […]

OBJECTIVE. The diagnosis of denervation injury as a cause of shoulder pain is conventionally based on clinical findings and electrophysiologic studies. MRI has an important role in identifying direct and indirect signs of neuropathy and can confirm the presence of nerve compression, depict space-occupying lesions, and exclude other intrinsic lesions of the s […]

OBJECTIVE. We summarize the rationale for and physiology of radiation therapy for the treatment of head and neck cancer and review the imaging findings of expected changes and complications after radiation to the neck. It is important to be able to recognize these features at all stages during management of patients with squamous cell carcinoma and other hea […]

OBJECTIVE. The purpose of our study was to subjectively compare additional mammographic views to digital breast tomosynthesis (DBT) in the characterizing of known masses, architectural distortions, or asymmetries. MATERIALS AND METHODS. Four experienced radiologists serially reviewed the imaging studies of 25 women with known masses, including full-field dig […]

OBJECTIVE. The purpose of this article is to propose a rule for determining which recommendation American Journal of Roentgenology (AJR) reviewers should provide when performing a review of a manuscript. CONCLUSION. The rule described here should allow reviewers to better understand the features that journal editors seek in a manuscript and to determine whic […]

OBJECTIVE. The objectives of this article are to review the new Response Evaluation Criteria in Solid Tumors (RECIST) guideline, version 1.1, highlighting the major changes in the new version compared with the original RECIST guideline (version 1.0), and to present case examples with representative imaging. CONCLUSION. Familiarity with the revised RECIST is […]

OBJECTIVE. The purpose of this review is to describe the current experimental and clinical data regarding the fundamentals and applications of 18F-FDG PET during acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). CONCLUSION. Lung inflammation is a key feature of ALI. During ALI, FDG PET can be used to monitor lung neutrophils, which are […]

OBJECTIVE. The use of PET, especially the use of PET/CT scanners, has expanded rapidly over the past few years. Although most of the detector development efforts have been focused on scintillator-based designs, other technologies, such as wire chambers, time projection chambers, and solid-state devices, are also being pursued. CONCLUSION. Many of these new t […]

OBJECTIVE. There is growing interest in using PET/CT for evaluating early response to therapy in cancer treatment. Although widely available and convenient to use, standardized uptake value (SUV) measurements can be influenced by a variety of biologic and technologic factors. Many of these factors can be addressed with close attention to detail and appropria […]

OBJECTIVE. At some institutions, catheter angiography is used for confirmation of aortic injuries and equivocal MDCT findings. Because of the speed and efficiency of 64-MDCT, we believe that diagnostic catheter angiography may be obsolete. The purpose of this study was to review our experience with 64-MDCT in the evaluation of acute traumatic aortic injury ( […]

OBJECTIVE. The purpose of this study was to describe the thoracic radiologic findings of chronic granulomatous disease in adults. MATERIALS AND METHODS. We retrospectively analyzed the chest radiographic and CT findings in four adults with chronic granulomatous disease during five episodes of lower respiratory tract infection. RESULTS. Chest radiographic fin […]

OBJECTIVE. The objective of our study was to evaluate the detection rate of central airway stent complications using MDCT as compared with bronchoscopy. MATERIALS AND METHODS. A review was performed of all consecutive patients undergoing MDCT and bronchoscopy for suspected complications of airway stents during an 18-month period. MDCT images were interpreted […]

OBJECTIVE. The purpose of our study was to show the usefulness and limitations of contrast-enhanced time-resolved MR angiography (MRA) for imaging the central veins of the chest. CONCLUSION. Time-resolved MRA is highly sensitive for the detection of abnormalities and is particularly useful in conjunction with static high-spatial-resolution MRA. However, seve […]
