Virtual colonoscopy aces speed-reading test
Radiologists could face a dramatic increase in workload if virtual colonoscopy becomes the modality of choice for colon cancer screening. A study presented at the May American Roentgen Ray Society meeting found that reading exams in less than five minutes with only a minor decrease in sensitivity is feasible.
Radiologists could face a dramatic increase in workload if virtual colonoscopy becomes the modality of choice for colon cancer screening. A study presented at the May American Roentgen Ray Society meeting found that reading exams in less than five minutes with only a minor decrease in sensitivity is feasible.
Dr. Philippe Lefere and colleagues at Stedelijk Ziekenhuis in Belgium studied the accuracy of two readers examining virtual colonoscopies from 180 patients. The first reader had a five-minute limit, while the second reader took as much time as needed to complete an interpretation.
The sensitivity of reader one was 76.2% for lesions 6 to 9 mm and 100% for lesions 1 cm or larger, for an overall sensitivity of 86.1%. Reader two had sensitivities of 85.7% and 100%, for an overall sensitivity of 91.6%.
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.
