Abstract:
High quality MR images of the gastrointestinal tract are now obtainable using a T2-weighted fast SE MR sequence with half-Fourier acquisition of data (the HASTE sequence). This fast sequence can acquire a set of images in a single breath hold and is insensitive to peristalsis-related artifact. It can be used with other imaging modalities in defining bowel obstruction and is accurate in determining the presence of bowel dilation and level of obstruction and in differentiating obstructing tumor from other causes of obstruction.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
