Article Synopsis
- The study aimed to determine percentiles for intrauterine placental growth and the placental to fetal growth ratio using MRI measurements in 107 singleton pregnancies at gestational weeks 27 and 37.
- Results showed that median placental volume increased from 513 cm³ at week 27 to 831 cm³ at week 37, while the placental to fetal ratio significantly decreased from 0.54 to 0.31 during the same period.
- The findings indicate that after week 27, fetal growth outpaces placental growth, highlighting the importance of understanding placental size variation for diagnosing potential abnormalities.
Introduction: Ultrasound is the diagnostic tool of choice in pregnancy. We lack valid ultrasound methods for placental size measurements. Our aim was therefore to compare three-dimensional (3D) ultrasound with magnetic resonance imaging (MRI) for measurements of placental volume.

Methods: We prospectively registered 875 biopsy procedures from 786 patients in one institution from January 27, 2012, to March 1, 2017, and recorded complications including pneumothorax with or without chest drainage, and multiple variables we assumed could be associated with complications. We performed multivariable logistic regression analysis to identify predictors of pneumothorax and pneumothorax requiring chest drainage.
Background: Femoral neck fractures are classified as nondisplaced (Garden types I and II) or displaced (Garden types III and IV) on the basis of anteroposterior radiographs. Cross-table lateral radiographs are important in the assessment of Garden type-I and II fractures as posterior tilt of the femoral head may influence treatment results. A posterior tilt of >20° has been associated with an increased risk of treatment failure after internal fixation, although the precision of these measurements has not been validated.

Magnetic resonance enterography [MRE] is an important diagnostic tool in evaluating CD. We aimed to assess the prevalence of inflammation and stricturing disease in patients with long-term CD, and to investigate associations with clinical factors.
