Primary uveal malignant melanoma - Radiopaedia.org
2024年6月18日 · CT is able to identify most uveal melanomas which appear as elevated, hyperdense sharply marginated lenticular or mushroom-shaped lesions, which enhance with the administration of contrast. MRI is the modality of choice for assessment of malignant uveal melanomas 5,6:
MRI of Uveal Melanoma - PMC - PubMed Central (PMC)
Uveal Melanoma (UM) is the most common primary malignant ocular tumor. The high soft tissue contrast and spatial resolution, and the possibility of generating 3D volumetric and functional images, make Magnetic Resonance Imaging (MRI) a …
Imaging of Uveal Melanoma—Current Standard and Methods in …
We reviewed imaging modalities currently used in the diagnostics of uveal melanoma, including fundus imaging, ultrasonography (US), optical coherence tomography (OCT), single-photon emission computed tomography (SPECT), fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), fundus autofluorescence (FAF), as well as positron ...
Diagnostic methods and therapeutic options of uveal melanoma …
2021年6月21日 · The diagnosis of uveal melanoma is based on ophthalmoscopy, biomicroscopy and ultrasonography (US). Magnetic resonance imaging (MRI) is useful in the event of untransparent lens or subretinal effusion.
Magnetic Resonance Imaging in the Clinical Care for Uveal Melanoma …
2023年5月30日 · For uveal melanoma (UM) patients specifically, multiple clinical applications of ocular MRI have been proposed [11, 22, 23, 24, 25, 26, 27, 28, 29, 30]. MRI makes it possible to obtain a complete 3D visualisation of the eye and orbit, without the limited penetration depth of ultrasound or fundoscopy [31, 32].
Intraocular tumors: evaluation with MR imaging. | Radiology
MR imaging is superior to CT in detection of intraocular tumors and may be more specific in diagnosis. Sixty-seven ocular tumors were studied with magnetic resonance (MR) imaging and computed tomography (CT). These tumors included primary uveal melanoma (n = 55), circumscribed choroidal hemangioma (...
Magnetic Resonance Imaging in the Clinical Care for Uveal Melanoma …
2023年5月30日 · As recent technical advances have increased ocular MRI’s diagnostic value, various clinical applications have been proposed. This systematic review provides an overview of the current status of MRI in the clinical care of uveal melanoma (UM) patients, the most common eye tumour in adults. In total, 158 articles were included.
MRI of Uveal Melanoma - PubMed
2019年3月17日 · Uveal Melanoma (UM) is the most common primary malignant ocular tumor. The high soft tissue contrast and spatial resolution, and the possibility of generating 3D volumetric and functional images, make Magnetic Resonance Imaging (MRI) a valuable diagnostic imaging technique in UM.
MR imaging characteristics of uveal melanoma with ... - Springer
2021年10月31日 · Knowing the MRI characteristics of UM is important in order to confirm the diagnosis and to differentiate UM from other intra-ocular lesions and because it has implications for treatment planning. MRI is a good technique to evaluate UM, being only limited in case of flat tumors or on identifying scleral invasion.
Clinical and Imaging Features of Noncutaneous Melanoma - AJR
2017年3月16日 · On MRI, melanomas are classically hyperintense on T1-weighted images, secondary to the presence of melanin, because of T1 signal shortening related to paramagnetic elements, including copper, manganese, and zinc.
