Incidence of Respiratory Pathogens in Naval Special Warfare Sea, Air, and Land Team Candidates With Swimming-Induced Pulmonary Edema.

Background: Swimming-induced pulmonary edema (SIPE) is a respiratory condition frequently seen among Naval Special Warfare (NSW) trainees. The incidence of positive respiratory panel (RP) findings in trainees with a diagnosis of SIPE currently is unknown.

Research Question: Does a significant difference exist in the incidence of respiratory pathogens in nasopharyngeal samples of NSW candidates with SIPE and a control group?

Study Design And Methods: Retrospective analysis of clinical information from NSW Sea, Air, and Land (SEAL) team candidates with a diagnosis of SIPE over a 12-month period.

Dual-Energy, Dual-Exposure PA and Lateral Chest Radiograph: Not Your Father's Chest X-Ray.

In the last two decades, our military and federal health care facilities have transitioned from traditional X-rays exposing film screen systems, developed much like photographic film, to an entirely digital detection system that affords computer processing of images and digital image and report distribution. While health care providers are well aware of the practicality of these advancements, they may not be aware of the improved diagnostic capabilities afforded by these new methods. In this report, we outline how application of physical principles of X-rays, with digital detectors and computer data manipulation, can present images demonstrating chest and heart diseases that were previously not readily visible by traditional film screen systems.

Opportunistic Detection of Coronary Calcium on Dual-Energy Lateral Chest Radiograph.

Heart disease remains the leading cause of death among men and women in the world. The majority of cardiac morbidity worldwide is secondary to atherosclerotic coronary disease. In this article, we discuss our experience using dual exposure, dual-energy lateral chest x-ray (CXR) technique to detect coronary calcium.

Multimodality Imaging Assessment of Anomalous Aortic Origin of the Left Main Coronary Artery Presenting With Syncope and Non-ST Elevation Myocardial Infarction.

Anomalous aortic origin of a coronary artery (AAOCA) is a rare congenital abnormality associated with myocardial ischemia and sudden cardiac death. We present a case of a 20 year old previously healthy male presenting with exertional syncope and non-ST elevation myocardial infarction. Coronary computed tomography angiography showed an anomalous left main coronary artery arising from the right coronary cusp with a slit-like appearance, acute angle origin, intramural course, and a subsequent inter-arterial course between the main pulmonary artery and the proximal aorta.

Lung Cancer Screening at a Military Treatment Facility: A Retrospective Review.

Introduction: Lung cancer is the leading cause of cancer death among men and women, accounting for more fatalities than colon, breast, and prostate cancers combined. Smoking causes about 85% of all lung cancers in the United States and is the single greatest risk factor. In 2013, the US Preventive Services Task Force (USPSTF) published initial guidelines for low-dose computed tomography lung cancer screening (LCS) among patients 55-80 years old, with a 30-pack-year history, who are current smokers or who quit within the previous 15 years.

Parathyroid Computed Tomography Angiography: Early Experience with a Novel Imaging Technique in Primary Hyperparathyroidism.

Objectives: To describe parathyroid computed tomography angiography (PCTA), determine its accuracy, and, as a secondary objective, calculate its mean radiation dosimetry.

Study Design: Retrospective chart review of patients who underwent parathyroidectomy for primary hyperparathyroidism from 2007 to 2015.

Setting: Single-center tertiary care academic military hospital.

Reversal of flow in the pulmonary artery: high-pitch spiral as a new method for dose reduction in functional imaging.

Advancements in CT technology lave led to substantial dose reductions for anatomic imaging of the heart. Here we illustrate an example where rapid repeat imaging with a high pitch spiral technique can image physiologic function. By optimal timing, and repeat sub second scanning, we illustrate an unusual case where direction of blood flow in the right pulmonary artery is reversed.

Gerbode defect with Staphylococcus lugdunensis native tricuspid valve infective endocarditis.

Coagulase-negative staphylococci are generally not considered to be very virulent; they are an uncommon cause of native valve endocarditis. Staphylococcus lugdunensis is an important exception and causes more severe infections, clinically mimicking S. aureus.

Recurrent Takotsubo cardiomyopathy.

We present the case of a 71-year-old woman with Takotsubo Cardiomyopathy as imaged with a dual source multidetector CT, MRI, and follow-up echocardiography. This demonstrates normal coronary arteries by use of CT angiography, and a 3D perspective of abnormal mid left ventricular hypokinesis and apical left ventricular akinesis.
