Paramagnetic Seeds: An Effective Option for Breast Lesion Localization
Paramagnetic seeds along with superparamagnetic iron oxide (SPIO) was an effective combination for nonpalpable breast lesion localization and sentinel lymph node detection (SLND), data from the MAGTOTAL trial in Sweden showed. The totally magnetic technique was equivalent to the use of guidewire and SPIO regarding re-excision frequency at 2.84% versus 2.87%, for a difference of […]
Paramagnetic Rim Lesions Highly Specific in MS Diagnosis
The presence of paramagnetic rim lesions (PRLs) on MRI was highly specific for multiple sclerosis (MS) in people suspected to have the disease, a prospective multicenter study showed. Based on 2017 McDonald criteria for MS diagnosis, the presence of one or more PRLs showed 88% specificity (95% CI 79-98%), 80% sensitivity (95% CI 68-91%), and […]
