Transthoracic Echocardiography: Beginner's Guide with Emphasis on Blind Spots as Identified with CT and MRI.

Radiographics 2021 Jul-Aug;41(4):1022-1042. Epub 2021 Jun 11.

From the Departments of Radiology (M.D.G., R.D.M., S.D.K., R.M.B., J.D.M., D.W.G., E.A.R.) and Cardiology (J.M.R.), Madigan Army Medical Center, 9040 Jackson Ave, Tacoma, WA 98431; and the Uniformed Services University of the Health Sciences, Bethesda, Md (M.D.G., J.M.R., D.W.G., E.A.R.).

Transthoracic echocardiography (TTE) is the primary initial imaging modality in cardiac imaging. Advantages include portability, safety, availability, and ability to assess the morphology and physiology of the heart in a noninvasive manner. Because of this, many patients who undergo advanced imaging with CT or MRI will have undergone prior TTE, particularly when cardiac CT angiography or cardiac MRI is performed. In the modern era, the increasing interconnectivity of picture archiving and communication systems (PACS) has made these images more available for comparison. Therefore, radiologists who interpret chest imaging studies should have a basic understanding of TTE, including its strengths and limitations, to make accurate comparisons and assist in rendering a diagnosis or avoiding a misdiagnosis. The authors present the standard TTE views along with multiplanar reformatted CT images for correlation. This is followed by examples of limitations of TTE, focusing on potential blind spots, which have been placed in seven categories on the basis of the structures involved: pericardium (thickening, calcification, effusions, cysts, masses), aorta (dissection, intramural hematoma, penetrating atherosclerotic ulcer), left ventricular apex (infarcts, aneurysms, thrombus, apical hypertrophic cardiomyopathy), cardiac valves (complications of native and prosthetic valves), left atrial appendage (thrombus), coronary arteries (origins, calcifications, fistulas, aneurysms), and extracardiac structures (primary and metastatic masses). .

Emergency Radiology: Current Challenges and Preparing for Continued Growth.

J Am Coll Radiol 2019 Oct 16;16(10):1447-1455. Epub 2019 May 16.

Department of Radiology and Imaging Services, Emory University, Johns Creek, Georgia.

The escalation of imaging volumes in the emergency department and intensifying demands for rapid radiology results have increased the demand for emergency radiology. The provision of emergency radiology is essential for nearly all radiology practices, from the smallest to the largest. As our radiology specialty responds to the challenge posed by the triple threat of providing 24-7 coverage, high imaging volumes, and rapid turnaround time, various questions regarding emergency radiology have emerged, including its definition and scope, unique operational demands, quality and safety concerns, impact on physician well-being, and future directions. This article reviews the current challenges confronting the subspecialty of emergency radiology and offers insights into preparing for continued growth.
