- MR Imaging of Carotid Artery Atherosclerosis: Updated Evidence on High-Risk Plaque Features and Emerging Trends
MR imaging is the criterion standard for carotid artery plaque characterization and is best able to characterize features of plaque vulnerability: lipid-rich necrotic core, intraplaque hemorrhage, ulcerations, loss of fibrous integrity, maximum plaque thickness, and plaque enhancement. Many researchers believe that many embolic strokes of undetermined source may originate from nonstenotic ipsilateral carotid plaques with vulnerable features. From the results of many trials, many believe that imaging markers of plaque vulnerability should be considered in the determination of carotid endarterectomy eligibility.
- Ecchordosis Physaliphora: Does It Even Exist?
Notochordal lesions span a spectrum of disease ranging from benign notochordal remnant (ecchordosis physaliphora) to low-grade to aggressively malignant. Benign notochordal remnant cannot be reliably distinguished from low-grade chordoma as they may have overlapping imaging features. Repeat imaging, beginning at 6-month intervals, is a more clinically relevant method for evaluating the malignant potential of these lesions.
- Long-Term Imaging Follow-up from the Management of Myelomeningocele Study
Prenatal repair of a myelomeningocele is associated with persistent improvement in posterior fossa imaging findings of Chiari II malformation at school age compared with postnatal repair.
