Those with parenchymal contusion would require frequent follow-up imaging because such contusions may grow large enough to become hemorrhage and exerts significant mass effect on the brain. [3] Cerebral microhemorrhages is a smaller form of hemorrhagic parenchymal contusion and are typically found in white matter. Such microhemorrhages are ...
For liver fibrosis assessment, percutaneous liver biopsy, with or without image guidance, is contraindicated in uncooperative people. [70] Transjugular liver biopsy is indicated for any person with diffuse liver disease who needs a biopsy but has a contraindication to percutaneous biopsy or needs a hemodynamic evaluation for diagnostic purposes.
The cause of IVH in premature infants, unlike that in older infants, children or adults, is rarely due to trauma. Instead it is thought to result from changes in perfusion of the delicate cellular structures that are present in the growing brain, augmented by the immaturity of the cerebral circulatory system, which is especially vulnerable to ...
CT of brain: 95ml [11] 80 ml [11] 75 ml [11] CT of thorax: Overall: 70 - 95 ml [notes 1] 60 - 80 ml [notes 1] 55 - 75 ml [notes 1] Parenchymal changes of the lung can often be evaluated adequately without the use of intravenous contrast. CT pulmonary angiogram: 20 ml [notes 2] 17 ml [notes 2] 15 ml [notes 2] Minimal amount when using specific ...
Cerebral edema is commonly seen in a variety of brain injuries including ischemic stroke, subarachnoid hemorrhage, traumatic brain injury, subdural, epidural, or intracerebral hematoma, hydrocephalus, brain cancer, brain infections, low blood sodium levels, high altitude, and acute liver failure.
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is a condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
Hemosiderin deposition in the brain is seen after bleeds from any source, including chronic subdural hemorrhage, cerebral arteriovenous malformations, cavernous hemangiomata. Hemosiderin depositionon on the surface of the brain and spinal cord due to chronic bleeding in the subarachnoid space is known as superficial siderosis.
Fatty liver disease (FLD), also known as hepatic steatosis and steatotic liver disease (SLD), is a condition where excess fat builds up in the liver. [1] Often there are no or few symptoms. [1] [2] Occasionally there may be tiredness or pain in the upper right side of the abdomen. [1] Complications may include cirrhosis, liver cancer, and ...
