Aging blood on MRI (mnemonic) | Radiology Reference Article ...
Jun 20, 2024 · Aging blood on MRI is dependent on the varying MRI signal characteristics of hemorrhagic collections with time and can be very useful in correlating the imaging findings with the clinical picture. However, as it can be complicated to recall the MRI features of aging blood through the 5 stages of hematoma evolution, several mnemonics have been ...
Subdural hemorrhage | Radiology Reference Article
Feb 11, 2024 · Subdural hemorrhage/hematoma (SDH) is a collection of blood accumulating in the subdural space. Subdural hemorrhage can happen in any age group, is mainly due to head trauma and CT scans are usually sufficient to make the diagnosis.
Hemorrhage on MRI | Radiology Reference Article - Radiopaedia.org
Oct 16, 2024 · Hemorrhage on MRI has highly variable imaging characteristics that depend on: the age of the blood. the type of hemoglobin present: oxy-, deoxy- or met-. whether or not the red blood cell walls are intact: i.e. intra- vs extracellular. the MRI sequence.
Intracerebral hemorrhage | Radiology Reference Article
Jul 23, 2024 · Intracerebral hemorrhage (ICH), or intraparenchymal cerebral hemorrhage, is a subset of an intracranial hemorrhage as well as of stroke, defined by the acute accumulation of blood within the brain parenchyma.

Hemorrhage on MRI has highly variable imaging characteristics that depend on: the age of the blood. the type of hemoglobin present: oxy-, deoxy- or met-. whether or not the red blood cell walls are intact: i.e. intra- vs extracellular. the MRI sequence.
Intracranial hemorrhage | Radiology Reference Article
Jun 20, 2024 · Intracranial hemorrhage is a collective term encompassing many different conditions characterized by the extravascular accumulation of blood within different intracranial spaces. A simple categorization is based on location: intra-axial hemorrhage. intracerebral hemorrhage (ICH) basal ganglia hemorrhage. thalamic hemorrhage. lobar hemorrhage
Timeline diagram of MRI and CT characteristics of intracerebral …
Acute intraparenchymal hemorrhage (1 to 2 days): T1w signal intensity of the lesion center remains intermediate-to-low (depending on clot formation). T2w signal intensity of the lesion center drops in comparison to surrounding brain tissue (Desoxy-Hb effect). This depends greatly on hemorrhage size. There might be sedimentation.
Intraventricular hemorrhage | Radiology Reference Article
May 9, 2024 · The main treatment approaches for intraventricular hemorrhage can be divided into two: treatment of the underlying cause of hemorrhage (e.g. aneurysm, AVM) treatment of obstructive hydrocephalus. The latter may merely require careful monitoring of clinical state and serial CTs to assess ventricular size or may require ventricular drain placement.
Ischemic stroke | Radiology Reference Article - Radiopaedia.org
Jul 23, 2024 · Hemorrhage, most easily seen on susceptibility-weighted imaging (SWI), is not a good indicator of age. Although most commonly seen after 12 hours and within the first few days, it may occur earlier or as late as 5 days 10 .
Germinal matrix hemorrhage | Radiology Reference Article
Aug 21, 2024 · Germinal matrix hemorrhage can only occur when the germinal matrix is present and is therefore only seen in premature infants. Hemorrhages can be identified in 67% of infants born prematurely at 28-32 weeks 1 and 80% of infants born between 23 …
