MR imaging plays an important role in defining the extent of sinonasal tumors for staging, particularly assessing intracranial and orbital invasion, as well as perineural spread and lymph node metastases.
17 gru 2015 · MRI is useful for mapping tumor extent, differentiating tumor from obstructed secretions, delineating the internal character of the tumor (cellularity, vascularity, architecture), and evaluating for perineural tumor spread (PNTS).
12 wrz 2024 · Texture analysis of conventional magnetic resonance imaging and diffusion-weighted imaging for distinguishing sinonasal non-Hodgkin's lymphoma from squamous cell carcinoma. Eur Arch Otorhinolaryngol 2022 ;279(12):5715–5720.
4 dni temu · Differentiating malignant tumors from benign entities is another key role of imaging in sinonasal tumors—a process that relies on specific imaging features seen on CT and MRI. For instance, benign conditions typically demonstrate smooth, well-defined margins, displaced tissue planes, bone remodeling, and T2 hyperintense signal on MRI.
1 paź 2023 · SUMMARY: Sinonasal and skull base tumors are a heterogeneous group of neoplasms with considerable histologic variation and overlapping imaging features. In 2022, the World Health Organization updated the head and neck tumor classification, further emphasizing the importance of molecular data and genetic alterations in sinonasal neoplasms.
25 lip 2023 · 1. Introduction. Sinonasal malignancies are rare diseases, accounting for 3% to 5% of all head and neck malignant neoplasms [1]. They contain several histological subtypes with different clinical behaviors. Although the stage at presentation is highly predictive of survival, none of the existing staging systems are ideal.
