Comparison of Three Point-of-Care Ultrasound Views and MRI Measurements for Optic Nerve Sheath Diameter: A Prospective Validity Study
ConclusionOur findings suggest that absolute measurements should not be compared across different ultrasound orientations given the wide variability in the correlation between the ultrasound views used to assess the optic nerve sheath. The inferior and transverse ultrasound views are the most likely to yield high-quality images, although the specific view, for the best image, in an individual patient can vary. We would caution against absolute values of ONSD to indicate increased ICP, as it may be view dependent.
CONCLUSION: This study provides an initial guideline for researchers from both fields, that is, medicine and engineering. The analyses are shown and discussed in detail through images. This paper shows the significance of image processing platform for tumor detection automation. PMID: 31964329 [PubMed - in process]
AbstractMounting evidence suggests that the placenta is involved in nearly all abnormalities of pregnancy and fetal development. Traditional imaging evaluation of the placenta by ultrasound has more recently been complemented by MRI for complex cases requiring additional information, such as in the diagnosis of the placenta accreta spectrum (placenta accreta, increta and percreta). MRI can often help delineate the safest approach to delivery and adds diagnostic certainty to enable prognostication and to avoid potentially lethal complications. Increasingly, prenatal MRI has become the purview of the pediatric imager and is ...
CONCLUSION: Ultrasound could be as sensitive and specific as contrast-enhanced MRI for the diagnosis of subclinical synovitis and tenosynovitis.
This article provides a review of the spectrum of imaging findings in patients after pelvic floor repair with synthetic mid-urethral slings and vaginal mesh.
CONCLUSION: Superior conditions with new features of lung MRI were found during lung flooding with an unrestricted visualization of malignant nodules and clear demarcation of intra-pulmonary structures. This could lead to new applications of MR-based pulmonary interventions such as laser or focused ultrasound-based thermal ablations. PMID: 31950391 [PubMed - as supplied by publisher]
The aging process is characterized by the chronic inflammatory status called “inflammaging”, which shares major molecular and cellular features with the metabolism-induced inflammation called “metaflammation.” Metaflammation is mainly driven by overnutrition and nutrient excess, but other contributing factors are metabolic modifications related to the specific body composition (BC) changes occurring with age. The aging process is indeed characterized by an increase in body total fat mass and a concomitant decrease in lean mass and bone density, that are independent from general and physiological flu...
AbstractPurpose of ReviewThis review aims to summarize evidence regarding hepatocellular carcinoma (HCC) screening in the specific context of HIV infection and discuss areas of uncertainty.Recent FindingsIt has not been definitely established if HCC incidence in HIV/HCV-coinfected patients with cirrhosis is above the 1.5%/year threshold that makes screening cost-effective. Outside cirrhosis or HBV infection, available data do not support surveillance. The performance of currently recommended ultrasound (US) screening strategy is poor in HIV-infected patients, as rates of early-stage HCC detection are low. Magnetic resonanc...
A female neonate was born with 2 congenital defects of the skin and bone on her head. She was born at 35 weeks and 3 days of gestation with a birth weight of 1484 g (−2.92 SD). Apgar scores were 8 and 9 at 1 and 5 minutes, respectively. At 34 weeks of gestation, a wide part of the scalp and skull, from the parietal to the occipital region, was noted to be absent on ultrasound and fetal magnetic resonance imaging Therefore, skull aplasia of the fetus was suspected (Figure 1; available at www.jpeds.com).
We compared the assessment of active synovitis in knee osteoarthritis (OA) by utilising superb microvascular imaging (SMI) and conventional power Doppler (cPD) techniques, and then correlated each technique with paients' symptoms, radiographic features and magnetic resonance imaging (MRI)-detected synovitis. A subgroup of participants with symptomatic knee OA underwent dynamic ultrasound assessment for semi-quantitative scores for SMI and cPD in the suprapatellar, medial and lateral parapatellar knee recesses.
