Diffusion-weighted MRI in head and neck cancer
PURPOSE OF REVIEW Diffusion-weighted MRI (DWI) is a noninvasive imaging technique allowing some degree of tissue characterization by showing and quantifying molecular diffusion. Cell size, density and integrity influence the signal intensity seen on diffusion-weighted images. A number of recent reports suggest that this technique may have interesting applications in the evaluation of head and n...
متن کاملNon-Gaussian analysis of diffusion weighted MRI in head and neck cancer: a feasibility study
Figure 2 Axial MRI images from the oral cavity of patient 9. (a) PD image, (b) T2 STIR image, (c) realigned mean b=0 image, (d) ADCmono map. The red and white arrows in (b) indicate the primary tumor and metastatic nodes, respectively. Figures (e-f) display pixel-by-pixel calculation outcomes for the right node. (e) ADCmono (10 mm/s). (f) Dapp (10 mm/s), (g) Kapp, and (h) chi. Region (n) ADCmon...
متن کاملDiffusion-weighted MRI in head and neck radiology: applications in oncology
Extracranial application of diffusion-weighted magnetic resonance imaging (MRI) has gained increasing importance in recent years. As a result of technical advances, this new non-invasive functional technique has also been applied in head and neck radiology for several clinical indications. In cancer imaging, diffusion-weighted MRI can be performed for tumour detection and characterization, moni...
متن کاملNon-uniformity of Clinical Head, Head and Neck, and Body Coils in Magnetic Resonance Imaging (MRI)
Introduction Signal intensity uniformity in a magnetic resonance (MR) image indicates how well the MR imaging (MRI) system represents an object. One of the major sources of image non-uniformity in high-field MRI scanners is inhomogeneity of radio-frequency coil. The aim of this study was to investigate non-uniformity in head, head and neck, and body coils and compare the obtained results to det...
متن کاملDiffusion-weighted EPI- and HASTE-MRI and 18F-FDG-PET-CT early during chemoradiotherapy in advanced head and neck cancer.
MAIN PROBLEM Diffusion-weighted MRI (DW-MRI) has potential to predict chemoradiotherapy (CRT) response in head and neck squamous cell carcinoma (HNSCC) and is generally performed using echo-planar imaging (EPI). However, EPI-DWI is susceptible to geometric distortions. Half-fourier acquisition single-shot turbo spin-echo (HASTE)-DWI may be an alternative. This prospective pilot study evaluates ...
