To evaluate the role of endovascular treatment for controlling haemorrhage in haemodynamically unstable patients with pelvic bone fractures and to relate clinical efficacy to pre-procedural variables. ⋯ • The series presented is one of the largest in a single centre. • Arterial embolisation is a life-saving procedure in patients with pelvic haemorrhage. • In pelvic traumas associated with haemorrhage, prognosis is dependent upon prompt treatment. • Transfusion status is significantly related to clinical efficacy.

To assess a radiologist's detection rate of rib fractures in trauma CT when reading curved planar reformats (CPRs) of the ribs compared to reading standard MPRs. ⋯ • In major blunt trauma, rib fractures are diagnosed with Computed Tomography. • Image processing can unfold all ribs into a single plane. • Unfolded ribs can be read twice as fast as axial images. • Unfolding the ribs allows a more accurate diagnosis of rib fractures.

Analysis of normal-appearing white matter of multiple sclerosis by tensor-based two-compartment model of water diffusion.
To compare the significance of the two-compartment model, considering diffusional anisotropy with conventional diffusion analyzing methods regarding the detection of occult changes in normal-appearing white matter (NAWM) of multiple sclerosis (MS). ⋯ • Water diffusion was compared between the controls and multiple sclerosis patients. • A two-compartment model, considering diffusional anisotropy was selected for water diffusion analysis. • Axial and radial diffusion of fast and slow diffusion components were evaluated. • A new method was developed to obtain the metrics stably. • The metrics indicated high detectability of slight differences between the groups.

To investigate the effect of a radiation reduction program on total dose, fluoroscopy dose per second corrected for body habitus and degree of collimation in left varicocele embolizations (LVE). ⋯ • Left varicocele embolization can be performed with very low radiation doses. • The most effective real time radiation reduction measure is collimation. • There is a learning curve to achieving optimal collimation.

SHINKEI--a novel 3D isotropic MR neurography technique: technical advantages over 3DIRTSE-based imaging.
Technical assessment of SHINKEI pulse sequence and conventional 3DIRTSE for LS plexus MR neurography. ⋯ • SHINKEI provides homogeneous and superior fat suppression, shown by higher nerve and muscle-to-fat ratios. • SHINKEI shows better nerve signal-to-noise and contrast-to-noise ratios than 3DIRTSE. • SHINKEI enables nerve-selective images with increased conspicuity of smaller LS plexus branches. • SHINKEI should be considered in routine MR neurography of the LS plexus.
