Imaging update on soft tissue sarcoma

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Neck Epithelioid Sarcoma at an Unusual Location Mimicking Lymph Node Metastases of Nasopharyngeal Carcinoma: A Case Report

“…This mass can be mistaken sometimes for lymph node metastases of a head and neck malignancy such as nasopharyngeal cancer as was the situation with our patient [ 4 ]. Imaging can help to diagnose soft tissue sarcomas, especially MRI is an excellent test to evaluate local extension of soft tissue lesions [ 11 ]. The diagnosis of proximal ES is purely pathological, a competent anatomopathologist is required to accurately identify this tumor [ 12 ].…”

The role of positron emission tomography combined with computed tomography with 18F-fluorodeoxyglucose in the diagnosis of soft tissue sarcomas

“…Высокоэффективным методом в диагностике первичной ОМТ является магнитно-резонансная томография (МРТ). Она служит методом выбора для оценки объемных образований мягких тканей из-за высокой мягкотканной контрастности и играет большую роль в дооперационной и послеоперационной оценках ОМТ [11].…”

“…При этом оценивают признаки периостальной и эндостальной реакций или разрушения кортикального слоя. При подозрении на отдаленное метастазирование в легкие наиболее информативна динамическая визуализация -КТ органов грудной клетки (КТ ОГК) [11]. В протоколах наблюдения пациентов с установленным диагнозом СМТ любой степени злокачественности КТ ОГК проводится непосредственно при постановке диагноза, через 3-4 мес, 6 и 12 мес при динамическом наблюдении [12].…”

Feasibility of Arterial Spin Labeling Magnetic Resonance Imaging for Musculoskeletal Tumors with Optimized Post-Labeling Delay

“…Magnetic resonance imaging (MRI) is essential in the diagnosis of musculoskeletal tumors, providing detailed information before patients undergo surgery [ 1 , 2 ]. The T1- and T2-weighted images and chemical shift imaging differentiates tissue characteristics such as fat, fibrosis and chondroid components [ 1 , 2 ].…”

“…Magnetic resonance imaging (MRI) is essential in the diagnosis of musculoskeletal tumors, providing detailed information before patients undergo surgery [ 1 , 2 ]. The T1- and T2-weighted images and chemical shift imaging differentiates tissue characteristics such as fat, fibrosis and chondroid components [ 1 , 2 ]. In addition, functional MRI, such as diffusion-weighted imaging, perfusion-weighted imaging, and magnetic resonance spectroscopy, provides more biomarker information [ 3 , 4 , 5 , 6 ].…”
