Symptoms of neuromuscular dysfunction are quite common in patients with hypothyroidism. Structural changes of myelin and dysfunction of oligodendroglial processes in axons have pathogenetic significance in patients with neuropathies against the background of hypothyroidism. However, the etiopathogenesis of the development of neuropathies in hypothyroidism is not fully understood. Magnetic resonance imaging (MRI) is a modern imaging method that now provides an image of nerve trunks with a quality sufficient to assess their condition. The main task of MRI is to assess the difficult and atypical cases of nerve compression. We examined 26 patients diagnosed with hypothyroidism, including 8 patients with degenerative-dystrophic diseases of the spine, 1 patient — an anomaly of nerves and muscles, 2 patients were found to have the consequences of injuries, 1 patient was diagnosed with De-Kervin disease, and 14 patients with comorbidity, leading to nerve compression, was not found. The aim of the study was to assess the diagnostic capabilities of magnetic resonance imaging for compression-ischemic neuropathies of the hands in patients with hypothyroidism. Neurological examination and data from stimulation electroneuromyography allows you to accurately determine the area of investigation for MRI. The article shows the diagnostic capabilities of MRI, as well as its place in the diagnostic algorithm of compression-ischemic neuropathies of the hands in patients with hypothyroidism.

A reliablein vivoimaging method to localize transplanted cells and monitor their viability would enable a systematic investigation of cell therapy. Most stem cell transplantation studies have used immunohistological staining, which does not provide information about the migration of transplanted cellsin vivoin the same host. Molecular imaging visualizes targeted cells in a living host, which enables determining the biological processes occurring in transplanted stem cells. Molecular imaging with labeled nanoparticles provides the opportunity to monitor transplanted cells noninvasively without sacrifice and to repeatedly evaluate them. Among several molecular imaging techniques, magnetic resonance imaging (MRI) provides high resolution and sensitivity of transplanted cells. MRI is a powerful noninvasive imaging modality with excellent image resolution for studying cellular dynamics. Several types of nanoparticles including superparamagnetic iron oxide nanoparticles and magnetic nanoparticles have been used to magnetically label stem cells and monitor viability by MRI in the urologic field. This review focuses on the current role and limitations of MRI with labeled nanoparticles for tracking transplanted stem cells in urology.

AbstractStem cell-based therapy is a new therapeutic option that can be used in patients with cardiac diseases caused by myocardial injury. Cardiac magnetic resonance imaging (MRI) is a new noninvasive imaging method with an increasingly widespread indication. The aim of this review was to evaluate the role of cardiac MRI in patients with myocardial infarction undergoing stem cell therapy. We studied the role of MRI in the assessment of myocardial viability, stem cell tracking, assessment of cell survival rate, and monitoring of the long-term effects of stem cell therapy. Based on the current knowledge in this field, this noninvasive, in vivo cardiac imaging technique has a large indication in this group of patients and plays an important role in all stages of stem cell therapy, from the indication to the long-term follow-up of patients.

Abstract In the second part of this review, we will describe the ancillary imaging features of hepatocellular carcinoma (HCC) that can be seen on standard magnetic resonance imaging (MRI) protocol, and on novel and emerging protocols such as diffusion weighted imaging and utilization of hepatocyte-specific/hepatobiliary contrast agent. We will also describe the morphologic sub-types of HCC, and give a simplified non-invasive diagnostic algorithm for HCC, followed by a brief description of the liver imaging reporting and data system (LI-RADS), and MRI assessment of tumor response following locoregional therapy.
