Wb Dwi For Response Assessment Boston 2015 Youtube Objective. the purpose of this study is to evaluate the diagnostic performance of whole body (wb) dwi with background body suppression (dwibs) combined with calculation of the apparent diffusion coefficient (adc) value at 3 t compared with the diagnostic performance of 18f fdg pet ct for detecting bone metastases in patients with malignant tumors. subjects and methods. thirty nine consecutive. Conclusion: wb dwi and pet ct scans have similar overall accuracy for detecting mm lesions. the higher ppv of pet ct and npv of wb dwi make them complementary imaging modalities. the adc value for mm lesions is significantly lower than that for false positive lesions. an adc cutoff value of 0.745 × 10 3 mm 2 s results in sensitivity and.
Pdf Diagnostic Value Of Wb Dwi Versus 18 F Fdg Pet Ct For The Objectives to evaluate the diagnostic test accuracy of 18f fluorodeoxyglucose positron emission tomography computed tomography (18f fdg pet ct), whole body magnetic resonance imaging (wb mri), and whole body diffusion weighted imaging (wb dwi) for the detection of metastases in patients with non–small cell lung cancer (nsclc). methods medline, embase, and cochrane library databases were. Dwi (wbmri dwi) for the detection of bone metastases in high risk bca and pca patients. our goal was to reduce redundant bone imaging by study ing the added value of tomographic and hybrid imag ing techniques and wbmri dwi to standard approach which has been bs for many decades. material and methods patients. Magnetic resonance imaging (mri) and 18f fluorodeoxyglucose positron emission tomography–computed tomography (18fdg 18f fdg pet ct) are standard procedures for staging multiple myeloma (mm). diffusion weighted sequences applied to whole body mri (wb dwi) improve its sensitivity. we compared the number of mm bone focal lesions (fls) detected by 18f fdg pet ct and wb dwi and evaluated the. Ited. methods: this was a retrospective, single center study of 22 patients with mm enrolled from january 2018 to december 2019. all patients underwent wb dwi and 18f fdg pet ct. pathological and clinical manifestations, as well as radiologic follow up, were used for diagnosis. the overall accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of both.
