Normal Cardiac Anatomy and Anatomic Pitfall/Variance
Fig. 1.1 Schematic illustration of anatomy of the right atrium. The right atrium (RA) is composed of the appendage (arrow head), venous component, and the vestibule. The venous component is…
Cardiac Tumors
Fig. 19.1 Imaging characteristics of myxoma on CT and CMR. (a) Transthoracic echocardiography shows an echogenic mass attached to the interatrial septum. This mass has protruded to the left ventricle…
CT Technical Overviews
Fig. 21.1 ECG leads attachment. The number and preferred location of leads depend on the scanner type and design. ECG leads should be attached outside scan range to avoid artifact…
MR Technical Overviews
Objects/devices Safety Prosthetic heart valve or annuloplasty ring Not considered contraindication Implanted cardiac pacemaker Generally not safe (except MR-compatible new ICDs) Cardiac closure and occluder devices MR safe Implanted cardioverter-defibrillator…
Evaluation of Myocardial Ischemia Using Perfusion Study
Fig. 10.1 CT imaging protocol. (a) “Stress-first” protocol is the stress scan that is acquired followed by the rest scan, and the nitrate can be administered before the rest scan….
Cardiac Imaging to Guide Electrophysiologic Intervention
Fig. 3.1 Diagram of the cardiac conduction system and action potential. Firstly, the sinoatrial (SA) node at the junction between the superior vena cava and the right atrium initiates the…
Coronary Anatomy and Anomalies
Fig. 2.1 (a) Circle. The RCA and LCX make a circle along the both atrioventricular grooves. (b) Loop. The LAD and PDA make a loop along the anterior and posterior…
Plaque Morphology Evaluation by CT
Fig. 6.1 Invasive coronary angiography and intravascular ultrasound (IVUS) of the left anterior descending artery (LAD). (a) Invasive angiogram shows significant coronary artery stenosis in the proximal segment of LAD…
Nonatherosclerotic Coronary Artery Disease
Cause Age group Comments Pathologic mechanism Atherosclerosis Adults (>50 years) Most common cause of coronary artery aneurysm or ectasia Local mechanical stress from stenosis, atherosclerotic pathologic findings extending into tunica…
Acute Myocardial Infarction
Fig. 11.1 Schematic illustration of basic principles of late gadolinium enhancement (LGE). Time-intensity curve at normal and pathologic myocardium after administration of contrast media (arrow) 11.2.1.2 LGE: Comparison with Other…
