  • • Pericardial disorders often distort normal cardiac anatomy. Therefore, obtaining classic views may require careful image planning.

  • Note: Pericardial diseases have characteristic anatomical features, but the diagnosis remains a clinical and hemodynamic one.

Pericardial Effusion

Effusive Constrictive Pericarditis

• Obtain steady state free precession (SSFP) cine images in two, three, and four chamber cardiac orientations.

• Above are four chamber SSFP cine views of representative pericardial disorders.

3. Stacked Axial SSFP Cine

• Stacked axial SSFP cines are useful to determine pericardial regions of interest and the extent of involvement.

T1W Spin Echo

T2W Spin Echo

• Pericardial cysts (white arrows) often are located at the right diaphragmatic border and are characterized with T1 weighted and T2 weighted turbo spin echos (TSE).

• T1 weighted TSE sequences (Image 1) demonstrate hypointense (dark) signal in the pericardial cyst.

• T2 weighted TSE sequences (Image 2) demonstrate hyperintense (bright) signal in the pericardial cyst which contains proteinaceous fluid.

• Correctly identifying the pericardium requires that it be delineated from fat and fluid. To do so often is aided by acquiring both a T1 weighted TSE and a T1 weighted fat suppressed gradient echo (GRE) sequence.

• T1 weighted TSE sequences (Image 1) produce hyperintense (bright) epicardial and pericardial fat (yellow arrows), hypointense (dark) pericardium (white arrow), and, if present, hypointense (dark) pericardial fluid. No pericardial fluid is seen in this case.

• Note: Normal pericardium is ≤ 3mm thick.

• T1 weighted fat suppressed GRE sequence (Image 2) nulls signal from epicardial (yellow arrow) and pericardial fat. In contrast, the pericardium appears bright (white arrow).


6 gre tagged imaging constrictive pericarditis

6. GRE tagged imaging: Constrictive pericarditis

• Myocardial tagging is integral to the determination of pericardial adherence to the epicardium. Normal pericardium should slip over the epicardial surface.

Note: Fluid and fat do not “hold” tags.

• Often a left ventricular short axis tagged cine in the atrioventricular groove can be very helpful for identifying the presence and extent of pericardial constriction.
