Nitroxyl compounds, and diagnostic media based thereon useful for enhancing NmR imaging. The use of NMR imaging as a diagnostic tool is only about 15 years old. The simplest such substituents are alkyl, preferably of carbon atoms, e. Library of Economics and Liberty. It is an object of this invention to provide a method for producing an enhanced NMR image of a CSF-containing portion of the body of a vertebrate. The reaction was stirred at room temperature for 24 hrs, filtered and the solution was evaporated to dryness in vacuo. The next morning, Iran hit another ship, the U. Contrast-enhanced diagnostic imaging method for monitoring interventional therapies. A method according to claim 11, wherein the nitroxide is 4- N,N-dimethyl-N-ethylamino -2,2,6,6-tetramethylpiperidinoxyl chloride, bromide or iodide. Daly San Francisco.
Black Monday was an event that took place on Monday, October 19, when stock markets around the world crashed.

The crash began in Hong Kong and. It can take just four or five such distribution days before a bull market ends and a bear market begins. In a distribution day, the index must fall at least % and volume must rise vs. the prior day. The Dow Jones industrial average acted more or less the same. At the next day's.

Stock investors of a certain age remember where they were on October 19, — what they did, how they felt, how they reacted to the stock-market crash. The plunge — known as “Black Monday” — saw the Dow Jones Industrial Average DJIA, +% lose % in one trading session.
A method according to claim 1, wherein the portion of the body being scanned is a cross section of the spinal canal, wherein the amount of charged nitroxide injected is less than 0.
The remaining oil was taken up in water, saturated with NaCl, the pH lowered toand then extracted with ether. Congressman Edward J. Ordinarily, less than 1 mmole and as little as 0.

Images of two cross-sections of the cranium and four cross-sections of the spinal column at various points below the point of injection were obtained as controls.

Rosen, G. The term "charged" nitroxide as used herein means the nitroxide compound possesses, in addition to the nitroxyl group, a functional group which at physiological pH possesses a charge, either positive or negative, e. DEC2 en. Either way, program trading ended up taking the majority of the blame in the public eye for the stock market crash.

Therefore, there is considerable interest in NMR image-enhancing agents which, when present in an area of the body containing CSF, enhance the emitted signal by reducing the relaxation time of the CSF in the area subjected to the NMR image.
To a solution containing 7. Although NMR imaging without the aid of an imaging enhancing agent is capable of distinguishing the subarachnoid space from the discs, the use of a contrast agent of this invention allows one to gain useful information while employing T 1 -weighted imaging with its inherent high signal-to-noise ratio, thus making NMR a much more valuable diagnostic modality in the evaluation of this pathology.
Because the loss in image enhancement is due to CSF turnover rather than decomposition of the nitroxide or passive diffusion thereof across the spinal cord, this procedure can be employed to study turnover of the CSF.
