Kinks and bucklings of the optic nerve as well as infarctive cysts distinguished the glioma CT-scan patterns from the meningiomas. Distinctive axial CT-scan features of the meningiomas not shared ...

Exposure to radiation from head or neck CT imaging increased risk for childhood brain tumors, according to results of a ...

A computed tomography scan or CT scan uses X-rays and computers to make images of the body. It can sometimes help doctors diagnose headaches and their causes. You might need one if you have ...

"This process is like a cosmic CT scan, where we can look through different slices of cosmic history and track how matter clumped together at different epochs." A powerful combination of data from ...

Bright areas on the scan can indicate active tumor growth. The presence of contrast enhancement often suggests a high-grade glioma, meaning the tumor is more aggressive and may require intensive ...

The focus is on practical and theoretical considerations for accurate quantitative parametric imaging. Recommended CTP scan parameters to maintain CT number accuracy and optimize radiation dose versus ...

Accurate detection and segmentation of lung tumors on CT scans is critical for monitoring cancer progression, evaluating treatment responses and planning radiation therapy. Currently, experienced ...

PET scans are routinely used in combination with computerized tomography (CT). The study is commonly referred to as PET/CT scan. PET scan is a nuclear medicine exam often used to help diagnose cancer, ...

Nearly 40% of children undergoing CT scans for blunt abdominal trauma have incidental findings, with 3.5% requiring immediate evaluation and 5.4% needing follow-up within 4 weeks. This secondary ...

Pediatric low-grade gliomas represent the most common childhood brain tumor class. While often curable, some tumors fail to respond and even successful treatments can have life-long side effects. Many ...

For patients with completely resected low-grade gliomas, observation may be a viable strategy. This approach involves close monitoring with regular imaging studies, such as MRI or CT scans, to detect ...
