Intravoxel Incoherent Motion MR Imaging in the Head and Neck: Correlation with Dynamic Contrast-Enhanced MR Imaging and Diffusion-Weighted Imaging

Abstract: ObjectiveTo investigate the correlation between perfusion- and diffusion-related parameters from intravoxel incoherent motion (IVIM) and those from dynamic contrast-enhanced MR imaging (DCE-MRI) and diffusion-weighted imaging in tumors and normal muscles of the head and neck.Materials and MethodsWe retrospectively enrolled 20 consecutive patients with head and neck tumors with MR imaging performed using a 3T MR scanner. Tissue diffusivity (D), pseudo-diffusion coefficient (D*), and perfusion fraction (f) were … Show more

“…Because ASL and IVIM do not require contrast medium, these methods can be used as alternative DSC perfusion MRI techniques for patients with a contraindication to contrast medium. Furthermore, the IVIM method can generate diffusion parameters in addition to visualizing perfusion (5,6).…”

“…Perfusion plays a vital role in brain function and is an essential part of brain metabolism. Perfusion imaging is useful for evaluating tumor blood supply, particularly for the differential diagnosis of tumor stages (1)(2)(3) and in prognosis prediction (4) and treatment strategy (5) planning. In addition, perfusion can reflect the microvascular proliferation or angiogenesis of the tumor (1,6).…”

“…Pearson's correlation analyses were performed to evaluate the relationship between IVIM metrics and serum sCD40L level. Inter- and intra-reader variability of measurements of IVIM metrics were analyzed using intra-class correlation coefficient (ICC) of two-way random model with 95% confidence intervals ( 21 ). The ICC ranged between 0 and 1.00, with values closer to 1.00 representing better reproducibility.…”

“…Even during the early phases of the disease, the parameters of the apparent diffusion coefficient (ADC) may represent tissue microstructures or path physiological circumstances. Certainly, the ADC values could represent salivary gland function and xerostomia following RTH [8].…”
