Parotid gland tumors | Radiology Reference Article - Radiopaedia.org
2024年10月15日 · From a diagnostic and staging point of view, CT and MRI are the primary modalities, having complementary strengths. CT is readily available and excellent at imaging bony involvement. MRI is better at perineural spread. Ultraound is less relevant for diagnosis but enables biopsy (both FNAC and core biopsy).
Magnetic resonance imaging of parotid gland tumors: a …
2022年11月7日 · In this pictorial essay, we present selected images of a variety of benign and malignant parotid tumors and emphasize the MRI features that may be useful in their characterization. Salivary gland tumors are rare, accounting for roughly 2–6.5% of all head and neck tumors and about 0.5% of all malignancies [1, 2, 3].
Differential diagnosis of parotid gland tumours: which magnetic ...
Thus, magnetic resonance imaging (MRI) is considered the most appropriate method for the evaluation of parotid gland tumours owing to its high contrast resolution for soft tissues and capability of visualising deep lobe tumours; it also provides excellent morphological and volumetric assessment, a precise definition of the relationship with ...
MR Imaging of Parotid Tumors: Typical Lesion Characteristics in …
2011年8月1日 · We analyzed the following MR imaging parameters: signal intensity, contrast enhancement, lesion margins (well-defined versus ill-defined), lesion location (deep/superficial lobe), growth pattern (focal, multifocal, or diffuse), and extension into neighboring structures, perineural spread, and lymphadenopathy.
Differentiation of Benign and Malignant Parotid Gland Tumors with MRI ...
This study investigated the effectivity of Magnetic Resonance Imaging (MRI) findings and Apparent Diffusion Coefficient (ADC) value in evaluating parotid gland tumors (PGTs), and aimed to reduce the biopsy procedure before surgery.
Multiparametric magnetic resonance imaging of parotid tumors…
2021年3月1日 · Multiparametric MRI is the imaging modality of choice for the investigation of parotid tumors. Some MRI features are highly suggestive of a specific diagnosis. Combining morphological features with diffusion-weighted imaging and dynamic-contrast enhanced imaging improves the capabilities of MRI for the diagnosis of parotid tumors.
We analyzed the following MR imaging parameters: signal intensity, contrast enhancement, lesion margins (well-defined versus ill-defined), lesion location (deep/superficial lobe), growth pattern (focal, multifocal, or diffuse), and extension into neighboring structures, perineural spread, and lymphadenopathy.
Differential diagnosis of parotid gland tumours: Application of …
2021年8月21日 · SWI is effective for differentiating benign and malignant parotid gland tumours. SWI offers incremental diagnostic value to DWI and DCE-MRI in parotid tumours. Parotid tumours (PTs) have a variety of pathological types, and the surgical procedures differ depending on …
Parotid Gland Tumors: Can Addition of Diffusion-weighted MR …
2008年12月1日 · Purpose: To determine the value of adding diffusion-weighted (DW) magnetic resonance (MR) imaging to dynamic contrast material–enhanced MR imaging when distinguishing between benign and malignant parotid tumors.
Parotid Gland and Other Salivary Glands Tumors | SpringerLink
2020年7月8日 · Parotid gland masses are most frequently benign tumors. In order to determine the most appropriate therapy, MR imaging is the best imaging tool to evaluate tumor topography, locoregional extension, relationship with the facial nerve, and even its nature, benign or malignant.
