A semiautomated method for measuring brain infarct volume.
An accurate, reproducible method for determining the infarct volumes of gray matter structures is presented for use with presently available image analysis systems. Areas of stained sections with optical densities above that of a threshold value are automatically recognized and measured. This eliminates the potential error and bias inherent in manually delineating infarcted regions. Moreover, t...
متن کاملBrain multi-infarct and decompression sickness
Scuba diving is associated with an important risk of developing decompression sickness secondary to formation of gas bubbles inside the body. The latter is formed mainly by nitrogen in the body on the diver’s way to the surface (1,2). In some cases, it might injure the central nervous system. Several decompression cases that have been associated with neurologic symptoms are described in the l...
متن کاملEvaluation of hyperacute infarct volume using ASPECTS and brain CT perfusion core volume
OBJECTIVE To compare the accuracy of Alberta Stroke Program Early Computed Tomography Score (ASPECTS) and CT perfusion to detect established infarction in acute anterior circulation stroke. METHODS We performed an observational study in 59 acute anterior circulation ischemic stroke patients who underwent brain noncontrast CT, CT perfusion, and MRI within 100 minutes from CT imaging. ASPECTS s...
متن کاملAutomatically measuring brain ventricular volume within PACS using artificial intelligence
The picture archiving and communications system (PACS) is currently the standard platform to manage medical images but lacks analytical capabilities. Staying within PACS, the authors have developed an automatic method to retrieve the medical data and access it at a voxel level, decrypted and uncompressed that allows analytical capabilities while not perturbing the system's daily operation. Addi...
متن کاملTranscranial laser therapy and infarct volume.
BACKGROUND AND PURPOSE Two randomized trials suggested that transcranial laser therapy (TLT) may benefit patients with acute ischemic stroke, although efficacy has not been confirmed. Supportive proof of concept could be demonstrated if TLT reduces the volume of cortical infarction. METHODS The NeuroThera Efficacy and Safety Trial-2 (NEST-2) was a randomized trial of TLT versus sham in patien...
