Radiographic prediction of meningioma grade by semantic and radiomic features
OBJECTIVES The clinical management of meningioma is guided by tumor grade and biological behavior. Currently, the assessment of tumor grade follows surgical resection and histopathologic review. Reliable techniques for pre-operative determination of tumor grade may enhance clinical decision-making. METHODS A total of 175 meningioma patients (103 low-grade and 72 high-grade) with pre-operative...
متن کاملMalignant Meningioma with Lumbar Spinal Metastasis (a case report)
Meningioma is considered as a benign central nervous system tumor that accounts for approximately 18% of all brain tumors. About 5% of meningioma tumors are malignant and have more aggressive clinical signs and worse prognosis compared to benign tumors. Extracranial metastasis of meningioma is rare but in the case of occurrence, it is more prevalent in lung, liver and lymph nodes. Osseous metas...
متن کاملCritique on Radiographic Density of Digitized Radiographic Weld Images Using Curve Fitting
Radiographic images can provide quantitative as well as quantitative information if they are subjected to densitometric analysis. Digital radiography consists of four major steps which include X-ray detection, digitization, image processing and display. The digitization process varies from device to device and may suffer variations even when the same digital equipment is used throughout time. A...
متن کاملSoft Tissue Masses Showing Low Signal Intensity on T2-weighted Images: Correlation with Pathologic Findings
Most soft tissue tumors show high signal on T2weighted images (T2WIs). Some tumors with the same histologic diagnoses showed different MR appearances in that some had a long T2 while others had a short T2 (1). Abundant collagen and marked hypocellularity or acellularity in a soft-tissue tumor or hemosiderinladen masses result in a decreased signal on T2WI (1, 2). Lesions with decreased signal i...
متن کاملGrade 2 meningioma and radiosurgery.
OBJECT World Health Organization Grade 2 meningiomas are aggressive tumors associated with a high recurrence rate leading to repeated surgical procedures, which can seriously worsen a patient's neurological status. Although radiosurgery is an increasingly popular technique, its role in the management of Grade 2 meningiomas has yet to be defined. In this study the authors aimed to evaluate radio...
