“…A recent prospective study of 96 patients used an approach that combined indirect CTV with direct CTV by adding a second injection of contrast material directly into the dorsal vein of the diseased limb. Using dual-source CT and fast-pitch technique, this yielded sensitivity of 95-97% and a specificity of 100% when compared to combination US and digital subtraction angiography (90).…”

Imaging plays an important role in the evaluation and management of acute pulmonary embolism (PE). Computed tomography (CT) pulmonary angiography (CTPA) is the current standard of care and provides accurate diagnosis with rapid turnaround time. CT also provides information on other potential causes of acute chest pain. With dual-energy CT, lung perfusion abnormalities can also be detected and quantified. Chest radiograph has limited utility, occasionally showing findings of PE or infarction, but is useful in evaluating other potential causes of chest pain. Ventilation-perfusion (VQ) scan demonstrates ventilation-perfusion mismatches in these patients, with several classification schemes, typically ranging from normal to high. Magnetic resonance imaging (MRI) also provides accurate diagnosis, but is available in only specialized centers and requires higher levels of expertise. Catheter pulmonary angiography is no longer used for diagnosis and is used only for interventional management. Echocardiography is used for risk stratification of these patients. In this article, we review the role of imaging in the evaluation of acute PE.

“…Duplex US, MR angiography, and CT angiography, as well as MR and indirect or combined CT venography are the primary noninvasive modalities for the diagnosis of arterial and venous thrombosis and thromboembolism in patients with COVID-19 (114,115). However, it is important to note that these disease processes may also be detected at routine contrast-enhanced CT performed in the portal venous phase, particularly when the main or large branch vessels are affected.…”

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) results in coronavirus disease 2019 (COVID-19), which was declared an official pandemic by the World Health Organization on March 11, 2020. The infection has been reported in most countries around the world. As of August 2020, there have been over 21 million cases of COVID-19 reported worldwide, with over 800 000 COVID-19-associated deaths. It has become apparent that although COVID-19 predominantly affects the respiratory system, many other organ systems can also be involved. Imaging plays an essential role in the diagnosis of all manifestations of the disease, as well as its related complications, and proper utilization and interpretation of imaging examinations is crucial. With the growing global COVID-19 outbreak, a comprehensive understanding of the diagnostic imaging hallmarks, imaging features, multisystemic involvement, and evolution of imaging findings is essential for effective patient management and treatment. To date, only a few articles have been published that comprehensively describe the multisystemic imaging manifestations of COVID-19. The authors provide an inclusive system-by-system image-based review of this life-threatening and rapidly spreading infection. In part 1 of this article, the authors discuss general aspects of the disease, with an emphasis on virology, the pathophysiology of the virus, and clinical presentation of the disease. The key imaging features of the varied pathologic manifestations of this infection that involve the pulmonary and peripheral and central vascular systems are also described. Part 2 will focus on key imaging features of COVID-19 that involve the cardiac, neurologic, abdominal, dermatologic and ocular, and musculoskeletal systems, as well as pediatric and pregnancy-related manifestations of the virus. Vascular complications pertinent to each system will be also be discussed in part 2.

“…Обобщая сказанное, необходимо помнить, что 3D-реконструкции не предоставляют полностью самостоятельной и надежной информации. Кроме применения упомянутых технических приемов для улучшения визуализации, а также возможности комбинации прямой и непрямой методик [11], соотношение с клиникой, данными УЗДС, а также просмотр и оценка снимков в нативном режиме являются обязательными у всех пациентов с патологией венозной системы.…”

“…Возвращаясь к проблеме острых тромбозов глубоких вен, нужно сказать, что несмотря на имеющиеся данные о возможности применения СКТ-венографии у этой категории больных, в том числе комбинации прямой и непрямой методик, учитывая риски ложноположительных и ложноотрицательных результатов, в нашем учреждении данное исследование в основном выполнялось только у пациентов с поражением илиофеморального и/или илиокавального сегментов [7,10,11,21].…”

Duplex ultrasound scanning (DUS) and magnetic resonance imaging are sometimes insufficient to meet our clinical needs due to specifics of given pathology and intrinsic technical limitations of these methods. This study aims to assess the need for multispiral computed tomography–venography (CT-venography) and to evaluate its diagnostic capabilities for various disorders in primary ambulatory patients in phlebology practice.Material and Methods. From January, 2017 to December,2019, a total of 10,112 patients sought initial consultation of a phlebologist. Upon examination, the physician assigned patients to one of the proposed categories using dedicated software. Analysis of these categories demonstrated the following pattern of morbidity: 2,167 patients (21.4%) had chronic venous disorders of class С0S-1 (CEAP classification); 4,460 patients (44.1%) had varicose veins of class C2-3 (CEAP classification); 351 patients (3.5%) had varicose veins of class C4-6; 570 patients (5.6%) had other diseases including post-thrombotic syndrome, acute thrombosis, thrombophlebitis, and venous malformations; and 2,564 patients (25.4%) were suffering from non-venous disorders. DUS was performed in all cases.Results. The study demonstrated that 260 patients required CT-venography constituting 2.6% of the total number of patients who came to the clinic in the indicated period. The direct venography with contrast medium injection through the peripheral veins was used in 156 cases (60%). Patients did not have any significant complications, such as acute kidney injury or worsening of chronic renal failure, severe allergic reactions to the contrast agent, or problems with the puncture site of peripheral veins.Conclusions: 1) CT-venography allowed to achieve the accurate three-dimensional imaging of the venous system, providing, in some cases, the necessary information for finding solutions on optimal management. 2) The need for CT-venography may occur in 2.6% of patients in ambulatory phlebology practice. 3) CT-venography is useful for diagnosing angiodysplasias, postthrombotic and non-thrombotic lesions, complicated varicose veins, especially in recurrence, and in some cases of acute deep vein thrombosis. 4) DUS is mandatory for hemodynamic assessment in all patients before CT-venography.
