[Computer tomographic diagnosis of pericardial effusions (author's transl)]
Insights
Computer tomography accurately diagnoses pericardial effusion and hematoma in patients. Contrast enhancement improves diagnostic accuracy, with findings confirmed by echocardiography or transthoracic puncture.
Area of Science:
- Cardiovascular Imaging
- Radiology
- Diagnostic Medicine
Background:
- Pericardial effusions and cardiac enlargement of unknown cause require accurate diagnostic methods.
- Computer tomography (CT) offers a potential imaging modality for evaluating these conditions.
Purpose of the Study:
- To evaluate the diagnostic accuracy of computer tomography for pericardial effusions and hematomas.
- To compare CT findings with echocardiography and transthoracic puncture.
- To identify CT criteria and assess the impact of contrast enhancement.
Main Methods:
- Thirty patients with suspected pericardial effusions or cardiac enlargement underwent computer tomography.
- Contrast enhancement was utilized in some cases.
- Diagnoses were confirmed using echocardiography or transthoracic puncture.
Main Results:
- Computer tomography correctly diagnosed pericardial effusion or hematoma in 19 out of 30 cases.
- Diagnostic accuracy was not dependent on the cause of the effusion.
- Contrast enhancement significantly improved the accuracy of computer tomography diagnoses.
Conclusions:
- Computer tomography is an effective tool for diagnosing pericardial effusions and hematomas.
- Contrast-enhanced CT enhances diagnostic precision.
- CT criteria can be reliably compared with echocardiography for differential diagnoses.
Abstract:
Thirty patients with suspected pericardial effusions, or with cardiac enlargement of unknown cause were examined by computer tomography. In 19 cases a diagnosis of pericardial effusion or haematoma was made. All these cases were confirmed by echo cardiography or transthoracic puncture. The accuracy of computer tomography diagnosis did not depend on the aetiology, but could be increased by contrast enhancement. The computer tomographic criteria are enumerated and compared with those of echo cardiography. Examples of the most important differential diagnoses are discussed.
