Imaging evaluation of uterine perforation and rupture.

Abdom Radiol (NY) 2021 Jun 15. Epub 2021 Jun 15.

Department of Radiology, University of Washington Medical Center, 1959 N.E. Pacific Street, Seattle, WA, 98195, USA.

Uterine perforation and rupture, denoting iatrogenic and non-iatrogenic uterine wall injury, respectively, are associated with substantial morbidity,and at times mortality. Diverse conditions can result in injury to both the gravid and the non-gravid uterus, and imaging plays a central role in diagnosis of such suspected cases. Ultrasound (US) is the initial imaging modality of choice, depicting the secondary signs associated with uterine wall injury and occasionally revealing the site of perforation. Read More

Robust multimodal registration of fluorescein angiography and optical coherence tomography angiography images using evolutionary algorithms.

Comput Biol Med 2021 Jun 2;134:104529. Epub 2021 Jun 2.

Department of Computer Science and Information Technologies, University of A Coruña, A Coruña, Spain; CITIC-Research Center of Information and Communication Technologies, University of A Coruña, A Coruña, Spain.

Optical coherence tomography angiography (OCTA) and fluorescein angiography (FA) are two different vascular imaging modalities widely used in clinical practice to diagnose and grade different relevant retinal pathologies. Although each of them has its advantages and disadvantages, the joint analysis of the images produced by both techniques to analyze a specific area of the retina is of increasing interest, given that they provide common and complementary visual information. However, in order to facilitate this analysis task, a previous registration of the pair of FA and OCTA images is desirable in order to superimpose their common areas and focus the gaze on the regions of interest.

Increased pulmonary embolism in patients with COVID-19: a case series and literature review.

Trop Dis Travel Med Vaccines 2021 Jun 12;7(1):16. Epub 2021 Jun 12.

Department of Anatomical Sciences, Faculty of Medicine, Kurdistan University of Medical Sciences, Sanandaj, Iran.

There is some recent evidence that the coronavirus disease 2019 (COVID-19) increases the risk of venous thromboembolism by creating a prothrombotic state. COVID-19 and pulmonary embolism (PE) are both associated with tachypnoea, hypoxemia, dyspnoea, and increased D-dimer. Diagnosis of pulmonary embolism in a patient with COVID-19 compared to an individual without it, using the conventional clinical and biochemical evidence is challenging and somehow impossible.

Radiographics 2021 Jun 11:200142. Epub 2021 Jun 11.

From the Departments of Radiology (M.D.G., R.D.M., S.D.K., R.M.B., J.D.M., D.W.G., E.A.R.) and Cardiology (J.M.R.), Madigan Army Medical Center, 9040 Jackson Ave, Tacoma, WA 98431; and the Uniformed Services University of the Health Sciences, Bethesda, Md (M.D.G., J.M.R., D.W.G., E.A.R.).

Transthoracic echocardiography (TTE) is the primary initial imaging modality in cardiac imaging. Advantages include portability, safety, availability, and ability to assess the morphology and physiology of the heart in a noninvasive manner. Because of this, many patients who undergo advanced imaging with CT or MRI will have undergone prior TTE, particularly when cardiac CT angiography or cardiac MRI is performed. Read More
