Measurement of liver volume using imaging techniques of various modalities

Abstract

Evaluation of liver volume is of great importance in the management of certain liver diseases and systemic disorders involving the liver. With the development of innovative technologies for the partial liver resection and transplantation lifetime assessment of liver volume is of great interest. The volume of the liver is a sensitive indicator for ectopic fat deposition and metabolic syndrome in obesity. Manual assessment of liver volume using percussion and palpation methods has disadvantages associated with the reliability and accuracy of the study, particularly in obese patients. Using formulas based on anthropometric measurements, it is possible to calculate the estimated size of a normal liver. Accurate non-invasive assessment of liver volume of the individual can be performed using imaging techniques. This article describes methods to measure the liver volume using imaging techniques of various modalities (CT, MRI, ultrasound). Ultrasonography is a simple, affordable and reliable tool for the structure and size of the liver estimates using formulas for calculating the volume of the liver.

Determination of hyperglycemia in patients with acute coronary syndrome

Abstract

In patients with acute coronary syndrome, hyperglycemia is observed, which is represented by elevated fasting plasma glycemia and glycated hemoglobin levels. It was found that an increase in the level of glycated hemoglobin was accompanied by an increase in the level of triglycerides, total serum cholesterol. At the same time, glycated hemoglobin correlated especially with the parameters of fat metabolism — total serum cholesterol, high-density lipoproteins, low-density lipoproteins and triglycerides. At the same time, the level of glycated hemoglobin mainly stayed in the values of 7—8 %, which corresponded to the figures of systolic blood pressure of 140—160 mm Hg; and a body mass index of 30 kg / m2, total blood serum cholesterol 6.0—6.5 mmol / l and an ejection fraction of 30—40 %. The article concluded that developing hyperglycemia in patients with ACS is associated with both risk factors of ACS, and with the manifestation and prognosis of this pathology.
