The term MR enterography and MR enteroclysis are similar, but the first is referred to a MR exam with orally administered enteric contrast media, and the second to a more invasive technique in which enteric contrast media is administered through the fluoroscopy-guided positioned nasojejunal tube.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
MRCP makes use of heavily T2-weighted MRI pulse sequences. [3] [7] These sequences show high signal in static or slow moving fluids within the gallbladder, biliary ducts and pancreatic duct, with low signal of surrounding tissue. Secretin is also given to a patient to increase ductal compliance, making imaging easier. [3]
MRI has the advantages of having very high spatial resolution and is very adept at morphological imaging and functional imaging. MRI does have several disadvantages though. First, MRI has a sensitivity of around 10 −3 mol/L to 10 −5 mol/L which, compared to other types of imaging, can be very limiting. This problem stems from the fact that ...
The physical basis of MRI is the spatial encoding of the nuclear magnetic resonance (NMR) signal obtainable from water protons (i.e. hydrogen nuclei) in biologic tissue. In terms of MRI, signals with different spatial encodings that are required for the reconstruction of a full image need to be acquired by generating multiple signals ...
Litter-Robot 3 Connect vs 4: Size Both devices are similar in footprint size, with the Litter-Robot 3 Connect measuring 24.25’’ x 27’’ and the Litter-Robot 4 measuring 22’’ x 27’’.
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
From tricky brain teasers to classic word games, many of us love a good challenge.So, it's no surprise that a viral riddle—known as the "30 Cows and 28 Chickens" riddle—is going around right ...
