The purpose of this study is to evaluate the relationship between DWI or PET/CT and prognostic factors of breast tumor, such as Ki-67 and Nottingham prognostic index value. The relationship between the apparent diffusion coefficient (ADC) values, maximal standard uptake value (SUVmax), Ki-67 and NPI groups were evaluated. ADC values showed a negative correlation of moderate strength with Ki-67; the ADC mean values in different prognostic groups of the NPI were significantly different. There was no statistically significant relationship between the parameters of SUVmax, Ki-67 and the values of NPI. The performed study demonstrated the interrelation of ADC values with the prognostic criteria of NST, which suggests the possibility of using the ADC as a non-invasive marker of survival.

Intricate complex of interconnected anatomical formations of the neck makes for multifactor manifestation in traumatic lesions of this zone. Consequently we consider it expedient to use syndromic approach to such lesions in radiologic diagnostics. 114 patients with cervical traumas were subjected to computed tomography examination. As a result of СТ-semiotics analysis the next syndromes were singled out: isolated lesions of soft tissues of the neck, traumatic lesions of the great vessels of the neck, lesions of the cervical aerodigestive organs, lesions of parenchimal organs of the neck, legions of the cervical part of the vertebral columb and spinal cord, cervicofacial, cervicocerebral, cervicocranial, cervicothoracal lesions. As a result of our investigations high efftctiveness of computed tomography was established for revealing and comprehensive description of various traumatic lesions of the neck organs and structures.

The aim of the study was to evaluate the additional contribution of single photon emission computed tomography/computed tomography (SPECT/CT), used in conjunction with planar bone scan (BS), in bone metastatic disease detection and its effect on the tactics of managing patients with breast cancer (BCa) and prostate cancer (PCa). The study included 1412 patients with established oncological diagnosis (BCa - 844 patients, BCa - 568 patients), to which «whole body» planar BS and SPECT/CT were performed. In all patients included in the study, the fact of bone metastatic disease was established by the results of additional imaging techniques and follow up. Bone metastatic disease was detected in 324 (23 %) patients and excluded in 1088 (77 %). SPECT/CT had higher diagnostic indices than planar BS. Sensitivity, specificity and accuracy of bone metastatic disease detection of planar BS were 91, 71, 76 %, of SPECT/CT, 97, 93, 94 % respectively. The additional use of SPECT/CT in the second stage after the planar BS in 337 (24 %) patients from the general group (n = 1412) led to a change in the results of the diagnostic test. The additional use of SPECT/CT in the second stage after the planar BS allows to change the results of the diagnostic test in the evaluation of bone metastatic disease in patients with BCa and PCa, which can significantly affect the management tactics of patients.

In the literature review, the diagnostic technique called proton magnetic resonance spectroscopy (1H-MRS) is considered to be gaining popularity. It allows non-invasive in vivo assessment of tissue metabolism and demonstrates effective application in improving the specificity of MR diagnosis of breast lesions and control of tumor response to neoadjuvant chemotherapy. Variations in the concentration of choline-based cellular metabolites detected by 1H-MRS have shown a relationship with malignant tissue transformation in in vivo and in vitro studies. 1H-MRS exists as a complement to the current MR study of the breast.

The studies contributed to establish the fact that only complex radiation examination using X-ray, MR-diagnostic allows to make a definitive diagnostic conclusion about posttraumatic changes in the ankle area in view of the pathology of bones, tendoligamentous apparatus, as well as to plan the scope of conservative and surgical treatment.

IgG4-related disease (IgG4-RD) is a fibroinflammatory condition characterized by the occurrence of tumor-like foci in different organs with a unique histological pattern. The kidney is a frequently affected organ with tubulointerstitial nephritis, the representative lesion of IgG4-RD. We describe a 57-year-old man with IgG4-related kidney disease in which relatively rapidly progressive nephropathy. MRI is an alternative for patients with renal function impairment and contraindication to contrast-enhanced CT. On T2-weighted images renal lesions are hypointense and hyperintensity on diffusion-weighted imaging at a high b value. A percutaneous renal biopsy revealed IgG4-related kidney disease. Prescribing of prednisolone 40 mg/day improved the renal function. A rapid response to corticosteroid therapy is a very important feature of IgG4-RD. When the patient was arbitrarily withdrawn glucocorticoids, a relapse with progression of renal dysfunction was observed.The clinical course of this case highlighted the importance of MRI imaging to facilitate the earliest diagnosis and effective therapeutic intervention.

Nowadays most experts who follow the modern global medical community trends are aware of the English language knowledge necessity at a basic level at least. The lack of the unified terminology, the multiple items of the same concepts, lots of obsolete terms, incorrect spelling, pronunciation of eponyms especially - all these things are the problem of Russian medical language as well. These factors combination was account the basis for the publications series creation entitled «English Terms Glossary» for the «Radiology - practice» journal, which will be published in subsequent issues.
