Purpose: To quantitatively evaluate reconstruction software algorithms in combination with algorithm O-MAR for correcting metal artifacts CT-images and explore the potential of using radiation therapy planning tasks. Material methods: A quantitative assessment on CT scans a 20 cm diameter cylindrical phantom hip joint implant center was performed. Test tubes different concentrations potassium hydrogen phosphate (K2HO4×3H2O) were placed around implant. The evaluation parameters used standard...
Retrospective cohort study. To evaluate the effectiveness of opportunistic osteoporosis screening using an artificial intelligence (AI) algorithm for detecting vertebral compression deformity (VCD >25%) and reduced bone mineral density (BMD) from routine chest computed tomography (CT) scans. Osteoporosis is insidious metabolic disease that often remains asymptomatic a long time, typically diagnosed due to occurrence complications. An approach diagnosing based on CT examinations, including...
Purpose of the study — to assess accuracy dual energy x-ray absorptiometry (DXA ) for measurements mineral bone density, content, area selected spine zone examination as well impact subcutaneous fat layer and correction auto-segmenting on mentioned parameters. Material Methods. The was performed iDXA scanner using designed phantom DMA PP2 lumber with inlays simulate (SF). To ensure correct assessment (precision accuracy) authors fivefold repeated scanning. Two modifications were used,...
Pathological low-energy (LE) vertebral compression fractures (VFs) are common complications of osteoporosis and predictors subsequent LE fractures. In 84% cases, VFs not reported on chest CT (CCT), which calls for the development an artificial intelligence-based (AI) assistant that would help radiology specialists to improve diagnosis prevent new fractures.To develop AI model automated thoracic spine based images.Between September 2019 May 2020 authors performed a retrospective sampling...
BACKGROUND: Computed tomography is the method of choice for assessing volume lung damage in viral pneumonia, including those associated with COVID-19. In addition, computed can determine main vessels size thorax. This allowed us to analyze relationship between severity COVID-19 and changes diameters pulmonary artery (PA) ascending aorta (Ao). Dilation PA a sign hypertension. The study these patterns may be clinical significance determining treatment tactics prognosis course disease.

Osteoporosis is defined as a systemic skeletal disease characterized by low mineral bone mass and microarchitectural deterioration of tissue. This consequently increases fragility susceptibility to fracture. affects every third woman fourth man over 50 years old. heavy burden for the health care Russian Federation, RUB25 billion annually. Up 31% women 4% men age need special therapy prevents destruction Identification these risk groups allows early treatment prevention pathological...
Backgraund:Osteoporosis (OP) is often diagnosed at the stage of complications. Compression fractures (CF) vertebral bodies, complications OP, and predictors subsequent are asymptomatic. CF can be detected on CT scan performed for other indications. We have analyzed approaches to using artificial intelligence services (AI services) generated diagnosing bodies. Aims:Testing AI identify based chest assess possibility their implementation into practice medical facilities Moscow Healthcare...
X‑ray density of biological tissues is an important diagnostic parameter. Metal structures in the CT scanning area distort it, creating artifacts. Thus, hip joint endoprostheses (HJE) often complicate visualization nearby soft tissue pelvic organs, which can interfere with qualitative and quantitative analysis changes when assessing prevalence oncological process this area. It possible to correct these distortions using software methods, bringing Hounsfield units (HU) values closer true...
Rationale. Quantitative CT (QCT) bone densitometry with asynchronous calibration not require a phantom during the scan procedure. Based on data it converts X-ray density in HU to mineral (BMD). Given large number of studies performed patients at risk osteoporosis, there is need for hands-on method capable assessing BMD short period time without tailored software or protocols. Goal. To develop QCT using an PHK (PHantom Kalium), compare volume measurements provided by from reputable developer....
.
Background. Dual-energy X-ray absorptiometry (DXA) is an effective method for bone mineral density (BMD) and subcutaneous fat percentage estimation. The constant development of new densitometry techniques, the demographic change higher potential artificial intelligence in healthcare enhance requirements high-quality measurements DXA.
 This study aimed to develop a quality control DXA scanners compare four systems with different geometries manufacturers when simulating fat-water...
Goal : To develop a method for automated assessment of the volumetric bone mineral density (BMD) vertebral bodies using an artificial intelligence (AI) algorithm and phantom modeling method. Materials Methods: Evaluation effectiveness AI designed to assess BMD based on chest CT data. The test data set contains 100 patients aged over 50 y.o.; ratio between subjects with/without compression fractures (Сfr) is 48/52. X-ray (XRD) at T 11 -L 3 was measured by experts 83 (205 vertebrae). We used...
Objective : to conduct the study of age distribution bone mineral density (BMD) by database dualenergy X-ray absorptiometry (DXA) and compare it with datа population NHANES study. Material methods . We used data from densitometry three-zone (total hip (TH), femoral neck (FN), lumbar spine) measured DXA two outpatient clinics. The obtained were compared III for TH FN 2005-08 spine. BMD value was corrected calibration coefficient each scanner. Adjustments also made sex age. Results Compared...
BACKGROUND: The FRAX tool (a 10-year fracture risk assessment) is recommended to diagnose osteoporosis and optimize the number of patients who need undergo X-ray densitometry. Due various circumstances, integration a full-fledged into digital circuits Moscow City Health Department problematic.
 AIM: study aimed develop calculator probability osteoporotic fractures routing for examination.
 METHODS: An optimized Half-FRAX was created based on from University Sheffield, which...
