PET avoids need for 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, Louisiana.

Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
