1711 Cesarean Scar Defect: Risk Factors and Comparison of Evaluation Efficacy between Transvaginal Sonography and Magnetic Resonance Imaging
The aim of this study is to determine the risk factors for development of cesarean scar defect (CSD), to compare the efficacy of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) for CSD assessment, further to investigate the association between CSD size and clinical symptoms.

Current clinical guidelines for surgical repair of abdominal aortic aneurysms (AAAs) are primarily based on maximum diameter assessment. From a biomechanical point of view, not only the diameter but also peak wall stresses will play an important role in rupture risk assessment. These methods require patient specific geometry which typically uses computed tomography (CT) or magnetic resonance imaging. Recently, wall stress analysis based on 3D ultrasound (US) has been proposed, and shows promising results.
Neither contrast-enhanced computed tomography nor magnetic resonance imaging can monitor changes in the pancreatic ductal adenocarcinoma microenvironment during therapy. We hypothesized that shear wave elastography could overcome this limitation. To test this hypothesis, we measured the shear modulus of two groups of murine pancreatic tumors (KCKO, n = 30; PAN02, n = 30) treated with stereotactic body radiation therapy (SBRT). The mean shear modulus of KCKO tumors was 7.651 kPa higher than that of PAN02 tumors (p
ConclusionAs a result of the systemic review and meta-analysis, we identified TVUS and MRI as good and comparable non-invasive imaging methods for diagnosisng adenomayosis, leading us to recommend TVUS as the first-line diagnostic imagin method and MRI as second if TVUS is inconclusive.
Lung cancer has been identified as the leading cause of cancer-related deaths worldwide and one of the most common malignancies in China . More and more non-small cell lung cancer (NSCLC) patients have been observed in the screening projects for detection of early stage lung cancer with the use of low dose computed tomography (CT) . Accurate imaging for evaluation of the Lymph Node Metastases (LNM) could affect the treatment of these patients . Many imaging modalities such as CT, Magnetic Resonance Imaging (MRI), Positron Emission Tomography-CT (PET-CT), as well as other diagnostic techniques like ultrasound-guide...
The purpose of this study is to correlate spinal ultrasound (US) and magnetic resonance imaging (MRI) findings in patients with anorectal malformations (ARMs).
The objectives of this study were to assess the diagnostic performances of 3-D RSG in deep infiltrating rectosigmoid endometriosis using surgery and pathology as the gold standard, and to compare its results with those of magnetic resonance imaging (MRI). Patients referred for endometriosis with symptoms suggesting deep infiltrating intestinal endometriosis (DIE) were included if they agreed to undergo a 3-D RSG and MRI and if there was a surgical indication related to endometriosis.
ConclusionThe volume of the lateral ventricles of infants with germinal matrix intraventricular haemorrhage can be estimated using 2-D cranial US images by application of a model.
AbstractExtension of tumor tissue within a vein is a recognized prognostic factor in abdominal malignancy because of its influence on tumor staging and selection of therapeutic management. With the advent of newer surgical techniques, and variable treatment strategies, imaging plays a crucial role in categorizing patients according to the tumor resectability and vascular reconstruction techniques during surgery. Understanding the clinical impact of tumor thrombus increases the awareness of the radiologist about the key findings in tumor staging and decision-making of surgical approach. Ultrasound (US), computed tomography ...
Authors: Bakewell C, Aydin SZ, Ranganath VK, Eder L, Kaeley GS Abstract Psoriatic arthritis (PsA) affects up to 30% of patients with psoriasis and may include musculoskeletal manifestations such as enthesitis. Enthesitis is associated with joint damage, and early detection and treatment are essential to management of the disease. Traditionally assessed by clinical examination and conventional radiography, entheseal inflammation can now be more accurately assessed earlier in the disease using techniques such as ultrasound, magnetic resonance imaging, computed tomography, and molecular imaging. However, there is litt...
