Imaging Technique | Features | Description | Advantages | Limitations |
---|---|---|---|---|
Two- or three-dimensional echocardiography | Echocardiography is usually the initial modality used for identification and evaluation of cardiac myxomas. |
|
|
|
MRI | Evaluation of cardiac masses and is of greatest value when echocardiographic findings are suboptimal or when the lesion has an atypical location or appearance. |
|
|
|
CT | CT can be used to accurately image the heart and surrounding mediastinum |
|
|
|
Angiography | Coronary angiography may be helpful to detect vascular supply of the tumor by the coronary arteries |
|
|
|
Chest x-ray | Chest x-ray has no particular findings associated with cardiac myxoma |
|
