PET avoids liver resection in colon cancer patients
A multicenter prospective trial in the Netherlands has found that FDG-PET prevents unnecessary surgeries for one in six patients with metastatic colon cancer who undergo liver resection based on CT findings.
A multicenter prospective trial in the Netherlands has found that FDG-PET prevents unnecessary surgeries for one in six patients with metastatic colon cancer who undergo liver resection based on CT findings.
Dr. W.J.G. Oyen of Radboud University Nijmegen Medical Center and colleagues enrolled 75 surgical candidates randomly selected for assessment with CT alone, the standard imaging for recommending surgery, and another 75 who were evaluated with CT and FDG-PET. All 75 patients in the CT group underwent laparotomy compared to 70 in the PET group. Overall, surgeries for 34 (45%) and 21 (28%) patients performed on the basis of CT or CT plus PET, respectively, were considered futile. Disease recurred within six months in almost a third of patients in the CT-only group. Oyen presented results at the 2008 SNM meeting in New Orleans.
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.
