To assess the feasibility of T2 mapping of lumbar facet joints and intervertebral discs in a single imaging slab and to compare the findings with morphological grading. ⋯ This study demonstrates the feasibility of a combined T2 mapping approach for the facet joints and intervertebral discs using a single axial slab.

To evaluate the diagnostic accuracy and variability of 3 semi-quantitative (SQt) methods for assessing right ventricular (RV) systolic function from cardiac MRI in patients with acquired heart disease: tricuspid annular plane systolic excursion (TAPSE), RV fractional-shortening (RVFS) and RV fractional area change (RVFAC). ⋯ RVFAC appears to be more accurate and reproducible than RVFS and TAPSE for SQt assessment of RV function by cardiac MRI.

Umbilical venous catheter position: evaluation by ultrasound.
Umbilical venous catheter (UVC) insertion is frequently performed in critically ill neonates, with catheter position evaluated by an abdominal radiograph. The position of the catheter can be difficult to assess based on supine film alone. We aimed to determine whether ultrasound enables precise evaluation of the catheter tip position. ⋯ Our study suggests that ultrasound is reliable and may replace plain radiograph for the identification of the UVC position, preventing complications from malposition, and reducing exposure to ionizing radiation.

Randomized Controlled Trial Comparative Study
A new kaolin-based haemostatic bandage compared with manual compression for bleeding control after percutaneous coronary procedures.
Bleeding and vascular access site complications are an important cause of morbidity after percutaneous femoral procedures. New haemostatic dressings have been developed to control heavy bleeding. To evaluate the efficacy of a new kaolin-based haemostatic bandage for femoral artery closure after diagnostic or interventional procedures compared with manual compression. ⋯ The haemostatic bandage obtained prompt and significantly shorter haemostasis than controls. This novel haemostatic device allowed for early ambulation without clinical complications.

CT of the hips in the investigation of protrusio acetabuli in Marfan syndrome. A case control study.
To establish the prevalence of protrusio acetabuli (PA) in adults fulfilling the Ghent criteria for Marfan syndrome (MFS), and in a normal adult population. ⋯ PA was found significantly more often in MFS persons than in controls. Our method was found to be robust and highly reproducible, giving a direct measurement of pelvic protrusion irrespective of pelvic shape.
