CT spot sign predicts hematoma expansion in stroke patients
By Eric Barnes
In patients with intracerebral hemorrhage (ICH), hematoma expansion in the first critical hours after symptom onset is associated with significantly poorer outcomes. Thanks to CT imaging and a new drug in the pipeline, it may be possible to identify and treat ICH patients at risk of hematoma expansion while there is time to improve outcomes, according to two new studies.

Dual-energy digital x-ray still looking for acceptance
By Wayne Forrest
Dual-energy subtraction has been available for almost 15 years as a method of differentiating soft tissue and bone to discover potentially cancerous nodules. Computed radiography (CR) and digital radiography (DR) are making dual-energy subtraction more readily accessible, and more clinicians and radiologists are making it part of their routines. But other healthcare providers wonder if dual-energy subtraction is worth the extra time it takes to produce and read the studies.

ASPECTS stroke scoring improved with perfusion CT
By Eric Barnes
The Alberta Stroke Program Early CT Score (ASPECTS) rates the presence or absence of ischemia in 10 regions of the brain. Paired with noncontrast CT when a patient presents with stroke symptoms, ASPECTS has been shown to effectively predict which patients will benefit from thrombolytic therapy. A recent study using perfusion CT has found that ASPECT increases the accuracy for predicting radiological and clinical outcomes over noncontrast CT.

The group compared the 90 mL (double) sodium phosphate cleansing regimen against that of a 45 mL (single) regimen, and found the single dose to be as effective as the double-dose regimen.
