NLS Diagnostic And Vascular Pathology
The NLS-method was developed in the mid 90-s played an essential role in in vascular pathology diagnosis. The main advantage of the NLS-method was that differentiate vessels from nonvascular structures, arteries from venis and very accurately detect sings of disturbed vascular permeability caused by stenosis or occlusion of the vessel lumen by an atheroscierotic patch or thrombus which are generally not visible on screening in B-mode alone.
In addition the NLS-method allows to diagnose portal hypertension, the extant of its intensity, and permeability of Porto systemic bypasses. NLS is very sensitive in defining the extend of peripancreatic vessel involvement with pancreas cancer which is essentially important for choosing the approach for surgical treatment. NLS allows to detected the damage renal vessels (both veins and arteries), which is very important for the correct choice of a hypotensive drug at arterial hypertension.
Some efficient hypertensive drugs, i.e. inhibitors of angoitensin-convering enzyme (ACE) such as capoten, enalapril, berliptil, cet., became very popular lately, but they have counter-indications at renal artery stenision. So physicians should bear in mind that checking for stension is a must before prescribing this kind of medicine. NLS-method is likely to be the choice method in such cases.
The NLS-method is indispensable fro differential diagnostics of benign and malignant hepatic diseases. Its sensitivity is comparable with the potential of conventional or digital angiography and computer assisted amplified tomography. In addition, the NLS-method is much cheaper, simpler and more intelligible. In can be employed directly at the patient's bedside if required. The NLS-method can be used in ophthalmology to check ocular hemodynamics before or after surgical intervention, in obstetrics to detect the disturbed blood current in umbilical cord arteries with a view to diagnose a retarded fetus development and predict a negative perinatal produce.
Summing up, the NLS-method is one of the most dynamic techniques and within the next few years it is bound to bring some new discoveries. NLS diagnostic devices (such as Bioplasm 17D NLS) with NLS-method are bound to have greater development.
