Perfusion-weighted MRIBlood circulationComputer simulationIn this study we investigated the effect of varying both concentration and dosage of an intravenously administered MR contrast agent on the concentration-time curve in brain tissue. Aside from injection time and injection rate, our model considers ...
you canreceive your state license. While not all states require this step, more than 75% of states have licensing laws, so it’s a good idea to get one or two (especially as a traveling MRI tech). Like getting certified, you’ll need to pass an ARRT-administered exam to earn your...
We explore techniques in positron emission tomography (PET), magnetic resonance imaging (MRI), second generation harmonic Imaging (SGHI), ultrasound (US), radiomics, and artificial intelligence (AI). A new diagnostic imaging tool in PET/computed tomography (CT) is the use of radiolabeled ...
We perform transaxial DWI and Gd FS T1WI if contrast media were administered, otherwise T2STIR sequences. Technical details (3 T) of the staging protocol are summarized in Table 1. Fig. 2 Value of complementary DWI and GdT1 to assess myometrial invasion. Endometrial cancer expanding the ...
Perfusion CT, or dynamic contrast-enhanced CT (DCE-CT), imaging employs standard low molecular weight iodinated contrast agents. When administered as an intravenous bolus, tissue concentration is dependent on vascular flow and interstitial accumulation, resulting in differential attenuation on CT imaging,...
Since living in cities is associated with an increased risk for mental disorders such as anxiety disorders, depression, and schizophrenia, it is essential to understand how exposure to urban and natural environments affects mental health and the brain. I
In contrast to that intriguing case, the last talk I attended was not very engaging, and bored, I contemplated the wooden writing tablet in front of me.The tablet is the shelf where you rest your notes. It was covered in graffiti incised into the surface with ballpoint pen; a jumble of...
The Test de Français International (TFI) is a language test administered by the Educational Testing Service. It assesses listening and reading skills and lasts for around 2.5 hours. Spanish Many people learn Spanish in order to study or work. As such, there are a range of Spanish proficien...
efficacy. These modifications involve changes in how the electricity is administered (both where in the brain, and how much), which in turn impacts the characteristics of the resulting seizure. What we do not completely understand is whether it is the changes in the applied electricity, or in ...
Contrast agents are substances which are administered to a patient orally or intravenously, and which x-rays cannot penetrate as easily. As such, an organ containing a contrast agent will allow a CT scanner to retrieve an accurate image of the area in question. Iodine solutions may be injected...
