8:30 AM- 10: AM


Theresa C. McLoud, MD, Lawrence R. Goodman, Ann N. C. Leung, Heber Macmahon, David Paul Naidich, John R. Mayo, and Alexander A. Bankier

Code: RC201


This session includes six sections. The first, Pulmonary Embolism Diagnosis: Guidelines and Beyond, in which attendees will become familiar with evidence-based guidelines for the imaging evaluation of patients with suspected pulmonary embolism. This section describes methods for dose reduction in pulmonary angiography. Attendees will learn the principles of perfusion imaging with dual-energy CT to review its current possibilities, limitations, and expected developments, and to describe the complementary roles of morphologic and functional imaging in acute PE. The section highlights the prevalence and clinical significance of sub-segmental PE. Attendees will get updated on the current concepts and controversies regarding the diagnosis of pulmonary embolism in pregnant patients. The second section is STR/ATS Guidelines for Evaluating Pulmonary Embolism in Pregnancy, which reviews the optimal imaging paradigm developed by a multidisciplinary expert panel. Attendees will learn more about optimized imaging techniques in daily practice. The third section is for Solid Nodules, which highlights the rationale for the Fleischner Society Guidelines for management of small nodules. Attendees will learn to apply the guidelines in a clinical setting. They will also recognize potential pitfalls in nodule detection and management.

The fourth section is Proposed Interim Guidelines for Sub-solid Nodules. It reviews the definition of sub-solid nodules. The section also discusses interim guidelines for the management of solitary sub-solid pulmonary lesions of varying sizes, in addition to interim guidelines for the management of multiple sub-solid pulmonary lesions. The fifth section, Fleischner Guidelines for Radiation Dose in Thoracic CT, highlights the contribution of medical radiation dose to population radiation dose. Attendees will understand the contribution of CT radiation dose to medical radiation dose. This section will educate participants on the two components of CT radiation dose reduction, optimization and justification. The section will also illustrate techniques for CT radiation dose optimization; it will include demonstrations of approaches for CT examination justification. The sixth section is Fleischner Glossary: Challenging and Controversial Terms, which frames the historical background of the Glossary. This section will lay out the rationale for the Glossary. It will also illustrate how the Glossary should ideally be used and how it deals with controversial terms.
