1 wrz 2009 · T2* relaxation is one of the main determinants of image contrast with gradient-echo MR sequences and forms the basis for many T2*-based applications, such as susceptibility-weighted imaging, perfusion MR imaging, functional MR imaging, and iron overload imaging.
Platinum seeds provide a superior detectability in comparison to gold seeds or coils on MRI images and are detected equally well by an image guidance system using orthogonal x-rays, making them a better choice for fiducial-based CT-MRI registration.

1 cze 2024 · This study aims to explore the feasibility of MRI-based habitat radiomics for predicting response of platinum-based chemotherapy in patients with high-grade serous ovarian carcinoma (HGSOC), and compared to conventional radiomics and deep learning models. Materials and Methods.
NO2 Platinum's more powerfully sustained hemodilation (continuous and amplified blood-surge to the skeletal muscles) generates the Perpetual Pump. Your pumps now come on fast and last all day. Plus, NO2 Platinum's "cell-signaling" ensures you can add new muscle even faster.
17 lip 2020 · A metal artifact reduction sequence (MARS) is intended to reduce the size and intensity of susceptibility artifacts resulting from magnetic field distortion. A variety of techniques are used for reducing metal artifacts at MRI, both for addressing artifacts due to the presence of metal in the image plane (in-plane artifacts) and for artifacts ...
1 lip 2008 · Steady-state sequences are a class of rapid magnetic resonance (MR) imaging techniques based on fast gradient-echo acquisitions in which both longitudinal magnetization (LM) and transverse magnetization (TM) are kept constant.
6 paź 2017 · Quantitative MR imaging is based on measurement and interpretation of tissue-specific parameters independent of experimental design, compared with qualitative MR imaging, which relies on interpretation of tissue contrast that results from experimental pulse sequence parameters.
