Implication

May support MRI differentiation of myxomas from thrombi; leaves open prospective validation in larger cohorts.

Key Points

The study aims to assess the signal intensity features of cardiac or paracardiac masses using different MRI sequences.
Fifteen patients underwent MRI with spin-echo, cine gradient-echo, gadolinium-enhanced spin-echo, and TurboFLASH sequences.
Masses were confirmed histologically (n=11) or through other imaging (n=4).
Signal intensity characteristics were analyzed for various mass types.
Myxomas exhibited an intermediate signal intensity on spin-echo (n=6) and low signal intensity on gradient-echo (n=6) with a 57% +/- 11% contrast enhancement.
Thrombus showed intermediate or high signal intensity on spin-echo images but minimal contrast enhancement.
Variable signal intensity was noted in other cardiac tumors, with no tumors showing low signal intensity on cine gradient-echo images.

Structured PICO

What are the signal intensity features of different cardiac masses on various magnetic resonance imaging sequences?

Population

15 patients with cardiac or paracardiac masses (myxomas n=6, thrombus n=4, other tumors n=5) with histologic confirmation (n=11) or confirmation with other imaging modalities (n=4).

Intervention

Magnetic resonance (MR) imaging with spin-echo (n=15), cine gradient-echo (n=15), gadopentetate dimeglumine-enhanced spin-echo (n=15), and TurboFLASH sequences (n=7).

Outcome

Signal intensity (SI) features and contrast enhancement patterns of cardiac masses.surrogate

Different MRI sequences, particularly contrast-enhanced and cine gradient-echo imaging, can help differentiate cardiac myxomas from thrombi based on signal intensity and enhancement patterns.
