The Congenital Pulmonary Airway Malformation Volume Ratio (previously known as Congenital Cystic Adenomatoid Malformation (CCAM) Volume Ratio) is a sonographic indicator that has …

To gauge the size of the CPAM relative to the size of the fetus, the volume is expressed as a ratio to the fetal head circumference known as the CAM-volume-ratio or CVR. The CVR …

Two decades ago, the CPAM-volume ratio (CVR) was first described as a tool to predict the development of hydrops, with this outcome found to be unlikely in fetuses with CVRs of ≤1.6 …

Nov 2, 2023 · CVR is a 3D (width: red arrow; depth: blue arrow; length: yellow arrow) sonographic indicator of the mass volume normalized for gestational age to evaluate fetuses at risk of …

Oct 17, 2018 · 一旦确诊，按超声诊断的基本要素进行胎儿外科的专业评估，根据肿块体积算出胎儿的肺头比（cystic volume ratio,CVR）值，评价有否胎儿心脏受压、纵隔有否受压移位、有 …

CVR measurements are relatively easy to measure, reproducible, and can be calculated based on transverse and sagittal views on 2D ultrasound. CVRs are helpful since they are adjusted for …

结果 68例均经产前超声检查发现胎儿胸部实性或高回声肿块,初次发现平均孕周24周(18～30周),均经2次以上超声检查确诊为BPS.68例胎儿中CVR＜1.6者56例(82.4％)；CVR≥1.6者12 …

Prenatal diagnosis of hydrothorax and/or increasing cystic volume ratio (CVR) until delivery preceded perinatal death in 3/5 (60 %). Absent mediastinal shift showed a neonatal morbidity …

If you are referred for a suspected CPAM/BPS, our team will perform a detailed Level II ultrasound to evaluate the findings, look at the size of the mass, and calculate a CVR (CPAM …

Sonographic findings were noted and measurements of mass-to-thorax-ratio (MTR), congenital pulmonary airway malformation volume-ratio (CVR) and observed to expected lung-to head …
