MRI of patients with cardiac pacemakers: a review of the medical literature.

AJR Am J Roentgenol. 2011 Feb;196(2):390-401

Authors: Zikria JF, Machnicki S, Rhim E, Bhatti T, Graham RE

OBJECTIVE: Numerous studies testing the use of pacemakers with MRI have been published. Our aim was to analyze these trials to determine the safety of MRI for patients with cardiac pacemakers. We performed a systematic search of peer-reviewed databases. A total of 31 articles were reviewed. CONCLUSION: The data are heterogeneous with regard to MRI being considered for patients with pacemakers, and the benefits of the imaging should outweigh the risks.

Frequency of use of imaging tests in the diagnosis of pulmonary embolism: effects of physician specialty, patient characteristics, and region.

AJR Am J Roentgenol. 2010 Apr;194(4):1018-26

Authors: Bhargavan M, Sunshine JH, Lewis RS, Jha S, Owen JB, Vializ J

OBJECTIVE: The purpose of this study was to ascertain whether clinical practice in diagnosing pulmonary embolism is consistent with recommendations in the literature and to explore variations in practice across site of care (e.g., emergency department), physician and patient characteristics, and geographic location. MATERIALS AND METHODS: Medicare 5% research identifiable files were analyzed. The cases of patients with emergency department visits or inpatient stays for a diagnosis of pulmonary embolism or for symptoms related to pulmonary embolism (shortness of breath, chest pain, and syncope) were identified. We determined the number of patients who underwent each type of relevant imaging test and evaluated variations in the first non-chest-radiographic test by site of care and treating physician specialty. Using logistic regression, we studied variations in the use of common imaging tests, exploring variations associated with patient characteristics, physician specialty, site of care, and geographic location. RESULTS: For patients in whom pulmonary embolism might have been suspected, the most common tests were echocardiography (26% of the patients), CT or CT angiography of the chest (11%), cardiac perfusion study (6.9%), and duplex ultrasound (7.3%). For patients with an inpatient diagnosis of pulmonary embolism, the most common tests were chest CT or CT angiography (49%), duplex ultrasound (18%), echocardiography (10.9%), and ventilation-perfusion scintigraphy (10.9%). For patients for whom pulmonary embolism might have been suspected, many large variations were found in practice patterns among physician specialties and geographic locations. There were fewer variations among patients with the inpatient diagnosis of pulmonary embolism. CONCLUSION: Physician practice in the diagnosis of pulmonary embolism is broadly consistent with recommendations. However, variations by physician specialty and geographic location may be evidence of inappropriate imaging.

Imaging findings in a fatal case of pandemic swine-origin influenza A (H1N1).

AJR Am J Roentgenol. 2009 Dec;193(6):1500-3

Authors: Mollura DJ, Asnis DS, Crupi RS, Conetta R, Feigin DS, Bray M, Taubenberger JK, Bluemke DA

OBJECTIVE: Although most cases of swine-origin influenza A (H1N1) virus (S-OIV) have been self-limited, fatal cases raise questions about virulence and radiology’s role in early detection. We describe the radiographic and CT findings in a fatal S-OIV infection. CONCLUSION: Radiography showed peripheral lung opacities. CT revealed peripheral ground-glass opacities suggesting peribronchial injury. These imaging findings raised suspicion of S-OIV despite negative H1N1 influenza rapid antigen test results from two nasopharyngeal swabs; subsequently, those results were proven to be false-negatives by reverse transcriptase polymerase chain reaction. This case suggests a role for CT in the early recognition of severe S-OIV.
