Acusphere raises $7.5 million
Ultrasound contrast agent developer Acusphere of Cambridge, MA, announced this month that it concluded a $7.5 million financing round led by Comdisco Ventures. The funds raised include $5 million in debt from Comdisco and $2.5 million in venture capital.
Ultrasound contrast agent developer Acusphere of Cambridge, MA, announced this month that it concluded a $7.5 million financing round led by Comdisco Ventures. The funds raised include $5 million in debt from Comdisco and $2.5 million in venture capital.
Acusphere plans to use the funds to develop AI-700, a gas-filled synthetic polymer ultrasound contrast agent. AI-700 expands the capabilities of echocardiograms to include the detection of myocardial perfusion. The firm plans to begin phase I clinical trials with AI-700 in early 1999.
In other Acusphere news, the company reported Nov. 17 that it has received two patents from the U.S. Patent Office. The first covers technology for incorporating sound-responsive gas-filled microspheres into ultrasound contrast agents. It addresses a problem that arises from the use of commercial agents: When injected into blood, the agents leak gas, which decreases their efficacy. Acusphere's newly patented technology better retains gas inside the contrast agent, reinforcing the diagnostic signal, according to the company.
The second patent covers technology that uses synthetic polymers in contrast agents, strengthening the agents' ability to function well under ultrasound power settings used for myocardial perfusion imaging.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
