PET vendor Positron could be headed for bankruptcy. An independent auditor has expressed "substantial doubt" that the company, which was among the pioneers of positron imaging, could continue much longer as a "going concern." The auditor's comments were reported in Positron's annual report, filed March 29 with the Securities and Exchange Commission. As of Dec. 31, 2001, the company had cash and cash equivalents of $635,000 compared with cash and cash equivalents and short-term investments of $2,201,000 a year earlier. Positron has accumulated a deficit of more than $54 million since its inception in 1983, according to the auditor's statement. Only about 19 of the company's Posicam PET scanners are currently in operation, 15 of them in the U.S. The company must increase system sales to become profitable, something it has not been able to do in its 20-year history, or obtain additional capital, according to the auditor.
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.
