Mucocutaneous and peripheral soft-tissue hemangiomas: MR imaging
Radiology
|April 1, 1987
Summary
Magnetic resonance (MR) imaging clearly defines the extent and location of hemangiomas, aiding treatment planning. This noninvasive technique offers superior contrast for evaluating these congenital vascular lesions.
Area of Science:
- Medical Imaging
- Radiology
- Pediatric Radiology
Background:
- Hemangiomas are common congenital vascular malformations.
- Their clinical management depends on precise localization and extent.
- Potential complications can be severe.
Purpose of the Study:
- To evaluate the utility of magnetic resonance (MR) imaging in characterizing mucocutaneous and soft-tissue hemangiomas.
- To demonstrate MR imaging's noninvasive capability in defining lesion extent and anatomical relationships.
- To compare MR imaging with other modalities like CT and angiography.
Main Methods:
- Retrospective review of 11 patients with hemangiomas.
- Analysis of MR imaging findings, including T1- and T2-weighted sequences.
- Comparison of MR imaging characteristics with clinical presentation and treatment plans.
Main Results:
- MR imaging effectively delineated the extent and anatomical relationships of hemangiomas.
- T2-weighted MR images showed high signal intensity for hemangiomas, offering excellent contrast with surrounding tissues.
- T1-weighted images showed low signal intensity, inferior for lesion extent evaluation. Phleboliths and major vessels were rarely visualized.
- MR imaging provided valuable information for therapeutic planning and monitoring.
Conclusions:
- MR imaging is a valuable noninvasive tool for assessing hemangiomas.
- Its superior contrast resolution, particularly on T2-weighted images, aids in surgical planning and treatment evaluation.
- MR imaging can guide therapeutic decisions for hemangioma management.
