Vascular Occlusions Detected by Magnetic Resonance Imaging
Key result
MRI reliably detects vascular occlusions, identifying venous thrombi as focal regions of increased signal.
- n=21
Why the study?
Vascular occlusions have received less attention in MRI studies despite its suitability as a noninvasive vascular imaging modality.
Population
21 patients with documented venous or arterial occlusions
Comparison
MRI detection of vascular occlusions vs documented occlusions
Design
Observational study using a 0.12-T developmental resistive MRI unit

Implication
MRI signal may aid thrombus visualization in select cases; leaves open diagnostic performance versus standard modalities in prospective studies.

Cite This Study
Choyke et al. (1985) conducted an observational in Venous or arterial occlusions (n=21). Magnetic resonance imaging (MRI) was evaluated on MRI appearance and detection of vascular occlusions. Magnetic resonance imaging detected documented venous and arterial occlusions in 21 patients, with venous thrombi generally appearing as focal regions of increased signal.
