David Eric Magarik Radiologist Winchester, VA Intravenous contrast clears in less than a day and much quicker if one drinks excessive fluids after the exam. Oral contrast usually by bowel activity, but fluids help. Expert Answers Should you get a dye for a lung CT scan? Have a question ...
The fact that MRI systems don’t use ionizing radiation, as other imaging devices do, is a comfort to many patients, as is the fact that MRI contrast materials have a very low incidence of side effects. Most facilities prefer not to image pregnant women, due to limited research of the ...
CT Scans are performed with contrast and without contrast. Contrast is a dye used to enhance your imaging and is only needed in specific instances. Check with your referring physician if you're unsure which CT scan is right for you. How does a CT scan work? Unlike a stationary X-ray tub...
For some procedures, especially intestinal and circulatory scans, the patient will need to take a contrast agent for the most accurate scans. Bone and other dense structures within the body are easily imaged with the CT scanner’s x-rays; however, soft tissue does not appear as readily without...
Contrast media are often used in conjunction with a fluoroscope. In fluoroscopy, the X-rays pass through the body onto a fluorescent screen, creating a moving X-ray image. Doctors may use fluoroscopy to trace the passage of contrast media through the body. Doctors can also record the moving...
On the basis of the regression analysis, CT perfusion values in the short bolus series were overestimated by 1% and those in the long bolus series were underestimated by 8%. CONCLUSION: Duration of contrast material bolus injection does not influence CT perfusion values substantially. The longer,...

Cells interact with the curved surfaces of many organs and, at a lower scale, with the rounded features of the extracellular matrix, which inherently links geometric form and biological function. The curvature of the extracellular matrix influences vital cellular processes by defining physical boundary...
