Trends in head and neck radiology

Abstract

Trends in clinical research of head and neck radiology are well described within four articles published in the European Radiology in the last 2 years. One constant top issue is to gain more, better or new morphological information by so-called "conventional" methods (CT, MRI) with thinsliced imaging including special reconstructions. The addition of functional or metabolic methods (e.g. diffusion-weighted MRI, dynamic contrast-enhanced MRI, positron emission tomography) to anatomical imaging is a further general trend in oncological radiology over the last few years and has been invaluable in head and neck radiology.

Sinonasal lymphoma: A primer for otolaryngologists

“…This technique, which reflects the motion of water in soft tissues, was originally used to differentiate malignant from benign sinonasal tumors. 60,88,[92][93][94][95] ADC values are typically lower in malignancies in comparison to benign skull base tumors and have been shown to be significantly lower in SN-NHL than in sinonasal carcinomas (Figure 2D). 81,88,96,97 Wang et al compared ADC values between DLBCL and ENKTL using a higher resolution DWI technique and found the mean ADC value of ENKTLs to be significantly higher than that of DLBCLs.…”

“… 91 Calculating apparent diffusion coefficient (ADC) following MRI with diffusion‐weighted imaging (DWI), distinguishing between DLBCL and ENKTL has become clearer. This technique, which reflects the motion of water in soft tissues, was originally used to differentiate malignant from benign sinonasal tumors 60,88,92–95 . ADC values are typically lower in malignancies in comparison to benign skull base tumors and have been shown to be significantly lower in SN‐NHL than in sinonasal carcinomas (Figure 2D).…”
