Comparative Study
Comparison of left and right ventricular volume measurement using the Simpson's method and the area length method.
To compare ventricular volume measurement using a volumetric approach in the three standard cardiac planes and ventricular volume estimation by a geometrical model, the Area-Length method (ALM). ⋯ In the setting of healthy volunteers the ALM method should not be used in 2ch and 4ch planes of the right ventricle because of lacking correlation of global functional parameters compared to those obtained in the sa plane. Using Simpson's rule functional parameters correlate well to each other in the different imaging planes.

To prospectively evaluate the technical success and immediate complication rates of temporary central catheter placement in a homogenous patient population with disorders of hemostasis. ⋯ US-guided placement of central vein catheters in patients with disorder of hemostasis is safe with high technical success and low complication rates. US guidance for central venous catheterization should be the preferred method in this group of patients, if available in the hospital setting.

To quantify the border versus centre enhancement of malignant breast tumours on dynamic magnetic resonance mammography. ⋯ The border/centre enhancement difference in malignant breast tumours is easily visualized on midfield dynamic magnetic resonance mammography. The dynamic behaviour is significantly correlated to histological features and receptor status of the tumours.

To evaluate retrospectively the efficacy and safety of radiofrequency ablation (RFA) in patients with spinal tumors. ⋯ RFA of primary and secondary spinal tumors, which were unresponsive to chemo- and radiotherapy and prone to progression, is a safe, resource-saving, and highly effective percutaneous technique in patients with nonresectable spinal tumors.

To evaluate inter- and intra-observer variabilities in breast sonographic feature analysis and management, using the fourth edition of the Breast Imaging Reporting and Data System (BI-RADS). ⋯ Because inter- and intra-observer agreement with the BI-RADS lexicon for US is good, the use of BI-RADS lexicon can provide accurate and consistent description and assessment for breast US.
