The article is devoted to the study of the potential use of PET/CT with 18F-FDG as an additional radiological criterion for assessing the status (phase) of the disease in patients with multiple myeloma (MM) by means of measuring such quantities as the volume of metabolic tumor value - MTV and total lesion glycolysis -TLG. We analyzed the results of 192 PET/CT studies with 18F-FDG in 86 patients with multiple myeloma. The results were divided into groups according to the determined status of the disease at the time of the study, where «1» - strict complete remission and complete remission (SCR; CR) (n = 72); «2» - very good partial remission and partial remission (VGPR; PR) (n = 38); «3» - stabilization disease (STB) (n = 16); «4» - progressive disease (Prog.) (n = 66). When pairwise comparison of the results obtained, significant (p > 0,05) differences in measuring the volume of MTV were found in groups «1» and «2»; «1» and «3»; «1» and «4»; «2» and «4»; in terms of TLG in groups «1» and «3»; «1» and «4»; «2» and «4». The results obtained indicate that these measured values are statistically significant (p > 0,05) in patients with MM in different phases of the disease, which allows us to speak about the possible use of PET/CT with 18F-FDG as an additional criterion for assessing the phase of the disease in patients with MM.

The article is devoted to the analysis of errors made by average medical personnel in the process of performing review X-ray mammography, leading to iatrogenic damage to the breast. Retrospectively, 24 425 sets of mammographic images of women aged 29-80 years, performed in different medical institutions of the Russian Federation, were studied. The main methodological defects in the work of X-ray technicians that affect the occurrence of diagnostic iatrogenies during radiation examination of the breast are identified.

During the course of this experimental study tomograms of extracted teeth were analyzed before and after filling the root canals with an endodontic material and fragments of broken metal instruments for root canal treatment. During the first stage of the experiment, untreated extracted teeth were scanned using cone-beam computed tomography and microfocus cone-beam computed tomography. A comparative assessment of capabilities of the two methods of cone-beam computed tomography based on examination of untreated root canals was carried out. The second part of the study will be dedicated to visualization of root canals that contain foreign high-density materials.

False splenic artery aneurysm (SAA) is a fairly rare pathology with a high mortality. The article provides information about the frequency of their occurrence, causes, methods of diagnosis and treatment available in the literature. Currently, minimally invasive endovascular treatments are increasingly being used for treating splenic artery aneurysms. Our own observations of patients with giant SAA have been described as an illustration. In the first case was used endovascular proximal embolization of the splenic artery with 2 Gianturko helices. In the second case we have described the spontaneous thrombosis after an accomplished bleeding. The most informative in the diagnosis of SAA are multislice computed tomography (MSCT), angiography, endo-ultrasound. Comparison of the results of these methods allows you to the most accurately diagnose and determine the treatment tactics. Due to the high risk of aneurysm rupture and high mortality it is important to emphasize the necessity of a complex approach using multiphase MSCT-research, both at the initial stages of the survey and during monitoring the effectiveness of the treatment.

The tactics of treating patients with myocardial infarction, especially after a history of revascularization procedures (coronary artery bypass grafting (CABG), stenting of coronary arteries), depends largely on the prevalence and severity of pathological changes in the heart muscle. Restoration of the contractile function of the myocardium in the basin of the affected artery is associated with the functional state of cardiomyocytes in the zone of planned revascularization. Conducting MRI of the heart with delayed contrast enhancement allows assessing the functional preservation of the myocardium and predicting the effectiveness of the planned endovascular treatment.

Рresented a report illustrating the low effectiveness of pharmacological treatment in a 51-year-old man with a corrected transposition of the great arteries combined with congestive heart failure. Also presented is a brief overview of the literature and possible echocardiographic diagnostic indicators relating to this unusual condition.
