An abdominalmagnetic resonance imaging(MRI,磁共振成像)scan is an imaging test that uses powerfulmagnets(磁体)andradio waves(无线电波). The waves create pictures of the inside of thebelly area(腹部). It does not use radiation (x-rays...

although the sensitivity of x-ray is believed to be significantly less than that of CT, as discussed later. Two key findings suggest small-bowel obstruction: dilated loops of bowel and air–fluid levels. Although normal bowel does contain
Our segmentation method works independently on MRI and CT-scan volumes and has been tested on a 44 patient dataset and 10 synthetic images. Segmentation and maximum diameter estimation were compared to manual tracing from 4 experts. An inter-observer study was performed in order to measure the ...
Abstract Magnetic resonance imaging (MRI) is a crucial modality for abdominal imaging evaluation of focal lesions and tissue properties. However, several obstacles, such as prolonged scan times, limitations in patients’ breath-hold capacity, and contrast agent-associated artifacts, remain in abdominal ...
A CT scan refers to an imaging technique that stands for computer tomography. It involves the use of more traditional imaging techniques, like x-rays, that are taken from multiple angles. The images are then analyzed by a computer to make a three-dimensional model of the tissues under ...
MRI CT or computerized tomography scan uses X-rays that take images of cross-sections of the bones or other parts of the body to diagnose tumors or lesions in the abdomen, blood clots, and lung conditions like emphysema or pneumonia. MRI or magnetic resonance imaging uses strong magnetic ...
The long acquisition time of MRI is closely related with k-space sampling. If it were possible to reconstruct images with partially sampled k-space data, it would improve the temporal resolution of MRI. To reduce the scan time, parallel imaging is often applied. Parallel imaging involves simulta...
Following the introduction of rapid, high-quality scan techniques and the development of new, tissue-specific contrast agents, the applications of MRI for abdominal imaging are experiencing unprecedented growth. This article examines the current status of liver and pancreatic MRI, highlighting technical ...
