Desenvolvimento da técnica de imagem de ressonância magnética (RM) de corpo inteiro livre de radiação para o estadiamento de crianças com câncer
Desenvolvimento da técnica de ressonância magnética de corpo inteiro livre de radiação para o estadiamento de crianças com câncer.
A research study on the diagnosis of spread of disease for children who have been diagnosed with solid tumors using a new whole body imaging technique and a new MR contrast agent (ferumoxytol). Standard tests that are used to determine the extent and possible spread of a child's disease include magnetic resonance (MR) imaging, computed tomography (CT), Positron Emission Tomography (PET) as well as bone scanning, and metaiodobenzylguanidine (MIBG) scanning. The purpose of this study is to determine if newer imaging tests referred to as whole body diffusion-weighted MR and whole body PET/MR can detect the extent and spread of the disease as accurately or even better as the standard tests (CT, MR and/or PET/CT). The advantage of the new imaging test is that it is associated with no or significantly reduced radiation exposure compared to standard CT and PET/CT imaging tests. The results of whole body MR and PET/MR will be compared with that of the conventional, standard imaging studies for tumor detecting.

Descrição da medida |
Prazo |
|---|---|---|
|
Area Under the Receiver Operating Characteristic Curve (ROC) of Maximum Standard Uptake Value (SUV)
Prazo: Baseline (day of scan), and 3 to 14 weeks post treatment (interval determined by tumor type and treatment protocol)
|
Clinical response prediction according to maximum Standard Uptake Value (SUV), assessed using receiver operating characteristic (ROC) curve analysis. Higher AUC values indicate better discrimination between responders and non-responders. |
Baseline (day of scan), and 3 to 14 weeks post treatment (interval determined by tumor type and treatment protocol)
|
|
Area Under the Receiver Operating Characteristic Curve (ROC) of Minimum Apparent Diffusion Coefficient (ADC)
Prazo: Baseline (day of scan), and 3 to 14 weeks post treatment (interval determined by tumor type and treatment protocol)
|
Clinical response prediction according to minimum Apparent Diffusion Coefficient (ADC) values, assessed using receiver operating characteristic (ROC) curve analysis. The area under the ROC curve (AUC) measures the ability of minimum ADC values to distinguish responders from non-responders, with higher AUC values indicating better predictive performance. |
Baseline (day of scan), and 3 to 14 weeks post treatment (interval determined by tumor type and treatment protocol)
|
|
Sensitivity and Specificity of WB-DW-MR Compared to 18F-FDG PET/CT
Prazo: 3 to 14 weeks post-treatment (interval determined by tumor type and treatment protocol)
|
Comparison of the sensitivity (true positive rate) and specificity (true negative rate) of WB-DW-MR scans versus standard 18F-FDG PET/CT scans for tumor detection and clinical response assessment, using imaging findings compared with the clinical reference standard (biopsy and/or follow-up imaging). |
3 to 14 weeks post-treatment (interval determined by tumor type and treatment protocol)

Signal-to-Noise Ratio as a Measure of Technical Optimization of Whole-Body Diffusion-Weighted MRI (WB-DW-MRI)
Prazo: Baseline (day of scan)
|
Signal-to-noise ratio (SNR) was assessed to evaluate and optimize pulse sequence parameters and b-values for whole-body diffusion-weighted MRI. SNR was calculated from signal intensity measurements obtained from bone marrow metastases and normal bone marrow regions on diffusion-weighted MRI images. b50 images provide higher signal-to-noise ratio and visualization of tissue perfusion/anatomy, while b800 images emphasize restricted diffusion associated with malignancy and suppress background tissue signal. |
