CT has become the imaging modality for emergency imaging of the heart, aorta and pulmonary arteries.  The purpose of this exhibit is to: Discuss technical pitfalls that result in pseudopathology Demonstrate intrepretative pearls that aid in making challenging diagnoses Illustrate post-operative findings that can be mistaken for pathology Review unusual pathology that may be encountered 

Cardiac: LA appendage thrombus vs pseuodthrombus RA thrombus vs crista semilunaris RA thrombus from RCC (keep on scanning!) Pacemaker lead through the wall of the RV   Unusual pathology (subtle metastatic disease to the heart, ventricular wall calcification) Thoracic aorta Pseudodissection due to cardiac pulsation artifact Post operative material mimicking pseudoaneurysm or leak after aortic root repair Elephant trunk prosthesis (don't mistake for dissection!) Pulmonary artery: Bolus tracking timing pearls and pitfalls Pseudothrombus due to mixing, motion artifact and saline flush Parenchymal infarct: range of CT appearances Incidental and subsegmental PE and the clinical conundrum they create Tumor thrombus Pulmonary embolism on non-contrast CT
