HUMAN PHENOTYPE - ANNOTATIONS

The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.

Definition:Hypointence (dark) appearance of the substantia nigra inmagnetic resonance imaging using susceptibility weighted imaging (SWI).
Comment:Susceptibility-weighted imaging (SWI) is a relatively new magnetic resonance (MR) technique that exploits the magnetic susceptibility differences of various tissues, such as blood, iron and calcification, as a new source of contrast enhancement. Low SWI signal intensity may suggest deposition of paramagnetic material.
Synonyms:exact_synonym: Low signal intensity in the substantia nigra on susceptibility-weighted imaging (SWI)
