(MSDS) Material safety data sheets are the internationally standardized way to document the hazardous properties of chemicals, radioactive materials and other hazardous agents. Chemical companies provide such data sheets, and collections of MSDS sheets are available.

A matrix is an array of numbers in rows and columns. The horizontal lines in matrices are called rows and the vertical lines are called columns. A matrix with m rows and n columns is called an m-by-n matrix (or mxn matrix) and m and n are called its dimensions. The matrix used in computed tomography determines the scan resolution. Matrices are useful to record data that depend on two categories, and to keep track of the coefficients of systems of linear equations and linear transformations. See also Image Resolution and Zooming. • •
(MIP) CT Angiography images can be processed by maximum intensity projection to interactively viewing volumes of data, where the CT number of each pixel is given by the minimum CT number through the volume. The MIP connects the high intensity dots of the blood vessels in three dimensions, providing an angiogram that can be viewed from any projection. Each point in the MIP represents the highest intensity experienced in that location on any partition within the imaging volume. For complete interpretation the base slices should also be reviewed individually and with multiplanar reconstruction (MPR) software. The MIP can then be displayed in a Cine format or filmed as multiple images acquired from different projections.

MD-Gastroview® (solution of 660 mg diatrizoate meglumine and 100 mg diatrizoate sodium Solution) is an iodinated oral contrast agent with lemon-vanilla-flavor. MD-Gastroview® is water-soluble and suitable for oral or rectal administration. MD-Gastroview® is indicated for radiographic and CT examination of the esophagus, stomach, proximal small intestine and colon, when a barium sulfate suspension is not feasible or contraindicated. A usual adult dose for abdominal CT is 240 mL of a solution prepared by diluting 25 mL (9.17 g iodine) to one liter with tap water. Less dilute solutions [up to 77 mL (28.26 g iodine) diluted to one liter with tap water] may be used when indicated. The dose is administered orally about 15 to 30 minutes prior to imaging in order to permit the contrast medium to reach the pelvic loops.
