Magnetic Resonance Imaging (MRI)

MRI Machine

Three-dimensional(3D) imaging is important role in modern diagnostic radiology. Magnetic Resonance Imaging (MRI) is one of the modern diagnostic radiology equipment that can create images of the human body. No radiation used and it is non-invasive because its only based on magnetic fields of the hydrogen atom in the body. MRI can also produce computer-generated images of the body tissues and organs. Basically, the images are two-dimensional(2D), where MRI produce images that are presented in slices from top to bottom but these 2D images cannot be produce to another plane without losing it significant image resolution. If the information needed is in other planes, the acquisitions need to be repeated at the planes needed. Since 2D imaging is not quite efficient, there is 3D MRI for medical used for nowadays. The 3D data only acquired one plane and the images for other planes also produced with the same 3D data set. In Addition, 3D imaging also allows the presentation of anatomic detail so this make it easier for the radiologist to manipulate images by removing or making them transparent of unwanted overlying structures or emphasizing areas of interest. These techniques make the radiologists and surgeons to understand anatomic relationships better. This 3D imaging is more productive for planning of surgical procedures such as preoperative evaluation of vascular and biliary ductal variations in living-related liver donors, assessment of vascular patency in patients undergoing surgical resection, preoperative liver and tumour volume measurements and virtual hepatectomy.
