Two and a half years worth of data suggest that CT is the most accurate, cost-effective imaging modality for diagnosing the causes of large bowel obstruction, according to investigators in the U.K.
Two and a half years worth of data suggest that CT is the most accurate, cost-effective imaging modality for diagnosing the causes of large bowel obstruction, according to investigators in the U.K.
Principal researcher Dr. Sathi Sukumar, a consultant radiologist at the University Hospital of South Manchester, and colleagues retrospectively reviewed 2400 CT reports on inpatient cases of suspected large bowel obstruction, large bowel dilatation, or pseudo-obstruction spanning 30 months of clinical practice. They identified 42 on whom clinical, endoscopic, and surgical follow-up data were available. The investigators found that CT was highly sensitive and specific in identifying the causes of dilated large bowel loops in these patients. They released preliminary findings at the 2008 American Roentgen Ray Society meeting.
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.
