Non-small cell lung cancer staging: efficacy comparison of integrated PET/CT versus 3.0 T whole-body MRI. Radiology. 2008;248(2):632–42.Yi CA, ... CA Yi,KM Shin,KS Lee,... - 《Radiology》 被引量: 305发表: 2008年 Is CT scan still necessary for staging in Hodgkin and non-Hodgkin...
Hybrid imaging comprises three imaging modalities: single-photon emission tomography (SPET)/computed tomography (CT), positron emission tomography (PET)/CT, and PET/magnetic resonance imaging (MRI). The potential benefit of these modalities has been evaluated with SWOT approach in neurology as well ...
PURPOSE To evaluate the diagnostic benefit of integrated 18F-FDG PET/MRI for whole-body staging of female patients with recurrent pelvic malignancies compared to MRI alone. METHOD AND MATERIALS 13 patients with suspected recurrence of cervical or ovarian cancer underwent whole body 18F-FDG PET/MRI ...
Before start of SABR, all patients underwent a CT-scan of the tumour and surrounding tissues, and in patients with bone metastasis a Magnetic Resonance Imaging (MRI)-scan was also performed, for target definition of the detected lesions. A vacuum matrass was used for immobilization purposes duri...
Integrated PET/MRI allows simultaneous acquisition of PET and multiple parameters including functional MRI sequences in a single examination, reducing scan time. While the consistency of the spatial distribution of amino acid PET with functional ...
The purpose of this study was to compare the ability of 18F-FDG PET/CT and contrast-enhanced MRI (CEMRI) to detect and grade venous tumour thrombus (VTT) and venous bland thrombus (VBT) in RCC and assess invasion of the venous wall by VTT. The PET/CT and
The advantages of PET/MRI versus PET/CT combined scanners include superior MR perfor- mances in soft-tissue contrast and reduced radiation dose of the combined study (a feature especially appreciated in cancer follow-up), but the main envisaged improvement is the possibility of fully exploiting ...
(Shore RM, Pediatr Ann. 2008;37:404-412), or infection/inflammation (Calfee DP, Wispelwey B, Semin Neurol. 2000; 20:353-360) but the absence of a mass on CT and MRI, as well as the lack of seizure activity at the time of the scan exclude the former and leave infection/...
We next sought to test whether synthetic PET scans will add additional value to the CT deep-learning model that has demonstrated high accuracy in predicting lung cancer risks using low-dose CT scan images for lung cancer screening.16 We applied the cGAN model to predict the risk of developing...
Compensation for the noise added by downscatter to the [sup 201]T1 image can be achieved by using a 15% lower dose of [sup 99m]Tc, a 15% increase in scan time and a 12% increase in [sup 201]T1 dose. In conclusion, the Monte Carlo-based down-scatter correction recovers lesion ...
