Abstract:
The propose of the present work is to study the potential of the 3-D contrast MR-angiography (MRA) in diagnosis of aortic dissection. The studied group consisted of 45 patients who as expected might have aortic dissection. 15 patients was observed in dynamics after surgical treatment. Total number of me performed contrast-MRA was 72. MRA has been performed on 1.5T MR tomograph Magnetom Vision (Siemens) with the of ultrafast sequenses Fisp and turbo-flash. Aortic dissection was diagnosed in 18 patients. The method of ce-MRA enables to make a precise diagnose of acute and chronic aortic dissection. This method is used for a dynamic follow up of the patients after the performed surgery.
Insights
Three-dimensional contrast-enhanced MR angiography (ce-MRA) accurately diagnoses aortic dissection in patients. This imaging technique is also valuable for monitoring patients post-surgery.
Area of Science:
- Cardiovascular Imaging
- Radiology
- Medical Diagnostics
Context:
- Aortic dissection is a life-threatening condition requiring accurate and timely diagnosis.
- Conventional diagnostic methods may have limitations in visualizing the entire aorta.
- 3D contrast-enhanced MR angiography (ce-MRA) offers a non-invasive imaging solution.
Purpose:
- To evaluate the diagnostic potential of 3D contrast-enhanced MR angiography (ce-MRA) for aortic dissection.
- To assess the efficacy of ce-MRA in diagnosing both acute and chronic aortic dissections.
- To determine the utility of ce-MRA for post-surgical follow-up.
Summary:
- This study investigated 3D contrast-enhanced MR angiography (ce-MRA) in 45 patients suspected of aortic dissection.
- ce-MRA was performed using ultrafast sequences on a 1.5T MRI scanner.
- Aortic dissection was diagnosed in 18 patients, demonstrating the method's precision for acute and chronic cases.
Impact:
- 3D ce-MRA provides precise diagnosis of aortic dissection, aiding clinical decision-making.
- The technique facilitates dynamic follow-up of patients after surgical intervention.
- This imaging modality enhances the management of aortic dissection patients.
