The article presents standards for performing and reporting of transrectal prostate ultrasound in adults. The document consists of ultrasound protocol, which describes the methodology of ultrasound examination performing, and ultrasound report, describing the examination results with final conclusion. The ultrasound protocol and ultrasound report comply with current national and international guidelines.

Amyloidosis is a systemic disease caused by accumulation of insoluble amyloid proteins in the tissues. Cardiac amyloidosis (CA) lead to a severe heart failure, which is often therapy resistant. The severity of heart failure does not correspond to the degree of decrease in systolic function of the left ventricle, since diastolic function is more impairing. Early diagnosis of cardiac amyloidosis is important due to the presence of treatment regimens for this disease nowadays. The “gold standard” for cardiac amyloidosis diagnosis is myocardial biopsy, but non-invasive diagnostic methods are also of great importance. The aim of the article is a review of the ultrasound signs of cardiac amyloidosis, including the use of modern technologies, which helps to suspect CA to provide a further examination.

Timely preoperative diagnosis of endometrioic cyst (endometrioma), as well as deep endometriosis remains relevant. The aim of the study was to assess the diagnostic value of ultrasound in patients with endometriomas and assess the combination of them with other foci of external genital endometriosis. The study based on retrospective analysis of a date of 95 patients with ultrasound signs of ovarian endometriomas, who underwent examination in MedicoProfi LLC – Borisov Medical and Diagnostic Clinic (Krasnoyarsk) during the period from January 2019 to October 2023. All of patients underwent surgery , followed by morphological evaluation. In the vast majority of cases, it was possible to detect a combination of endometriomas with one or more foci of deep endometriosis. Superficial peritoneal endometriosis and adhesions were found on surgery in all cases when endometriomas appeared isolated on ultrasound. The results of the study showed: endometriomas combined with deep endometriosis in 96.8% of cases. Thus, ultrasound detection of endometrioma is a very reliable sign of deep endometriosis presence. The “kissing ovaries” symptom in bilateral endometriomas can be considered as an absolutely reliable sign of the uterosacral ligaments endometriosis with specificity of 100% and positive predictive value of 100%. The presence of the “kissing ovaries” sign should be depicted in the conclusion of the ultrasound protocol, since it highly suggestive to obliteration of the pouch of Douglas and involvement of adjacent organs (fallopian tubes, intestines, ureters, etc.) in the endometrioid infiltrates, which is extremely important for the surgery planning, as well as in patients with infertility. There is an obvious need to introduce the extended pelvic ultrasound protocol to the diagnostic algorithm for patients with suspected endometriosis, which will more accurately describe the disease extension.

Objective: to compare the terms, definitions and measurement methods developed by the IETA group with the ultrasound criteria of chronic endometritis (CE) used in Russia.

Material and methods. A retrospective cohort study of 158 reproductive age women with clinical and laboratory diagnosis of CE was carried out. Sonographic examination was performed in the early or middle proliferative phase (cycle day 4–10 days) with the use of Affiniti70 ultrasound system (Philips, the Netherlands) with a multifrequency 3D endocavitary probe. Uterine corpus volume, endometrial thickness and volume were measured, followed by percentage endometrial/uterine volume ratio calculation, the so-called adjusted endometrial volume. Qualitative analysis of grayscale imaging included assessment of endometrial structure and echogenicity; closure or separation of the endometrial layers; contour of endometrial midline; the presence of acoustic artifacts, such as reverberation in the presence of gas or liquid in the uterine cavity, described by a number of authors. Relevant IETA descriptions were searched when assessing all qualitative CE features. In parallel, a qualitative score analysis proposed by the IETA group was carried out.Timely preoperative diagnosis of endometrioic cyst (endometrioma), as well as deep endometriosis remains relevant.

Results. The comparative analysis of endometrium description in CE indicates a similar measurement technique for endometrial and intrauterine lesions thickness, both proposed by the IETA group and used in our country. Most of the IETA descriptors for qualitative ultrasound findings may be used in CE diagnosis. However, there are no some significant ultrasound features for identifying the inflammation, such as marked and partially or completely thickened midline, as well as gas focuses within the endometrium or in the uterine cavity, in IETA description.

Conclusion. Terminology standardization allows compare the results and perform multicenter studies followed by meta-analysis for the diagnosis of chronic endometritis, if researchers use the similar descriptors.

A steady increase in average maternity age at the time of first childbirth lead to a higher risk of fetal chromosomal abnormalities. The Order No. 1130n of the Ministry of Health of the Russian Federation establish the screening protocol at 11–14 weeks of gestation with assessing the followed criteria of fetal chromosomal pathology: the nuchal translucency thickness, nasal bone measurement, ductus venosus pulsatility index, tricuspid regurgitation, and heart rate. The value of non-invasive prenatal testing (NIPT) in the early prenatal diagnosis of the most common chromosomal abnormalities, as the trisomies 21, 18, 13, and monosomy X is also increasing. Additionally, numerous other fetal karyotype abnormalities can also be suspected at 11–14 weeks of gestation by revealing a number of other ultrasound signs. The article presents the literature review on additional ultrasound signs of various, both more and less common, chromosomal abnormalities. Pathological signs, abnormalities of fetal anatomy and extrafetal structures in the first trimester, which could be used as additional ultrasound signs of chromosomal pathology of various organs and systems (central nervous system and head, heart and blood vessels, urinary system, abdominal organs, fetal skeleton, as well as the placenta, umbilical cord, amniotic membranes) are described in the article. Despite the use of NIPT, including its extended panels, there remains a need to use ultrasound to detect the signs of rarer, but no less significant chromosomal pathologies, such as triploidies, mosaic trisomies, rare autosomal trisomies, duplications, and deletions.
