    Opis:
    Introduction. Squamous cell carcinoma (SCC) of the larynx accounts for a significant percentage of all head and neck cancers. Aim. In this paper we determine the differences in magnetic resonance relaxation time (MRI) of water in cancerous and healthy larynx tissues. Material and methods. This study is aimed on T2 MRI modalities for monitoring morphology of larynx tissue. Results. Our results showed that T2 MRI relaxation time measured in larynx tissue can be used to assess early cancer condition of larynx tissues. The changes of T2 MRI correspond to tumor growth within normal tissue. Conclusion. The study showed potential of MRI for the non-invasive monitoring of larynx condition.

    Opis:
    Introduction. Glycosaminoglycans (GAGs) play a widespread role in tissue modelling. GAG polymers may affect several receptor pathways in parallel. Aim. To present difference in concentration of GAG in healthy and cancer tissues. Material and methods. The literature search was performed nd reviewed using selected keywords. Results. We revieved the methods of detection various types of glycans measured by Magnetic Resonance Imaging. Conclusion. MRI methodology provides an efficient tool forstudy of cellular composition. The use T1 aof T2 measurements to study cancer tissue is a promising assay.

    Opis:
    Introduction. Magnetic Resonance Imaging (MRI) coils technology is a powerful improvement for clinical diagnostics. This includes opportunities for mathematical and physical research into coil design. Aim. Here we present the method applied to MRI coil array designs. Material and methods. Analysis of literature and self-research. Results. The coils that emit the radiofrequency pulses are designed similarly. As much as possible, they deliver the same strength of radiofrequency to all voxels within their imaging volume. Surface coils on the other hand are usually not embedded in cylindrical surfaces relatively close to the surface of the body. Conclusion. The presented here results relates to the art of magnetic resonance imaging (MRI) and RF coils design. It finds particular application of RF coils in conjunction with bore type MRI scanners.

    Opis:
    Over the past few decades, magnetic resonance imaging (MRI) has proven to be extremely successful in medical applications. More recently, the biomedical applications of MRI have been gaining more use in the field of clinical pharmacy. In 1977, perfluorocarbon compounds (PFC), which form emulsions that can carry drugs, were analyzed by 19F MRI and emulsified PFC compounds have been investigated as potential blood substitutes since the early 1960s and now a wide variety of PFC compounds are currently available as 19F MRI biomarkers. Molecules with 19F substituents are particularly attractive for use in drug tracking by 19F MRI due to 100% 19F abundance, high 19F MRI sensitivity (0.83 relative to 1H MRI) and an impressively large chemical shift range (400 ppm). Another benefit in the use of 19F MRI is a zero background signal in biological samples due to lack of endogenous fluorine. Therefore, drugs containing fluorine atom have potential for 19F MRI imaging drug delivery to tissue. This article will review recent developments in the use of 19F MRI in imaging drug delivery to tissue and individual cells.

    Opis:
    Currently, liver disease is widespread and the awareness of these diseases is low. Early symptoms of liver disease do not necessarily indicate problems with this organ and patients are usually informed of their problems when the stage of the disease is already advanced. Invasive biopsies are the clinical diagnostic method most commonly used in the evaluation of liver disease. A biopsy is associated with a high risk of false results and additional complications. Finding new non-invasive imaging methods has led to the discovery of a new method called Magnetic Resonance Elastography (MRE). This technique allows one to evaluate the mechanical properties of tissues and to distinguish between pathological states. Testing using this technique can be performed on a conventional magnetic resonance system by using few additional components and properly prepared software. Studies have shown that there is a strong correlation between MRE-measured liver stiffness and the degree of fibrosis. MRE is also useful in characterizing liver tumors. Studies show that this technique is highly credible in both health volunteers and patients with liver fibrosis. MRE has tremendous diagnostic potential. The described technique is not currently widely used and has the 127-132potential to serve as a safe and accurate alternative in clinical diagnostics in the future.
