X-rays predict likelihood of death from SARS
A retrospective review of patients with severe acute respiratory syndrome revealed that chest x-rays taken seven days after onset of symptoms could predict the likelihood of death.
A retrospective review of patients with severe acute respiratory syndrome revealed that chest x-rays taken seven days after onset of symptoms could predict the likelihood of death.
Dr. Gregory Antonio and colleagues at the Chinese University of Hong Kong examined radiographic records for 313 SARS patients. They analyzed the percentage area of lung opacification and the number of lung zones affected, allocating radiographic scores accordingly. Univariate logistical regression models for these scores for each of the first 12 days after symptom onset showed day seven to be the earliest point at which reliable prognosis could be made.
"If patients could be stratified according to risk early in their illness, different arms of a treatment protocol could be devised, and individual treatment could be tailored," the researchers wrote in the March issue of the American Journal of Roentgenology.
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.
