To analyse diffusion-weighted MRI of acute spinal cord trauma and evaluate its diagnostic value. ⋯ • Multishot, navigator-corrected diffusion-weighted MRI is helpful when evaluating spinal cord injury (SCI). • Four types of SCI may be classified according to the DWI characteristics. • DWI differentiates cytotoxic from vasogenic oedema, thereby determining the centre of SCI. • DWI can assist in detecting intramedullary haemorrhage. • DWI can help evaluate the degree of compressed spinal cord.

Comparative Study Clinical Trial
Diagnostic accuracy and patient acceptance of MRI in children with suspected appendicitis.
To compare magnetic resonance imaging (MRI) and ultrasound in children with suspected appendicitis. ⋯ • In children, MRI has a higher sensitivity for appendicitis than ultrasound. • Ultrasound followed by MRI in negative or inconclusive findings is accurate. • The tolerance for ultrasound and MRI in children is comparable. • MRI can be performed in children in an emergency setting.

Comparative Study Clinical Trial
Comparison of 3D multi-echo gradient-echo and 2D T2* MR sequences for the detection of arterial thrombus in patients with acute stroke.
We compared a multi-echo gradient-echo magnetic resonance sequence (susceptibility-weighted angiography [SWAN]) with the T2* sequence for the detection of an arterial thrombus in acute ischaemic stroke. ⋯ • Multi-echo gradient-echo MR (e.g. susceptibility-weighted angiograph, [SWAN]) is increasingly used in neuroradiology. • Compared with conventional T2* sequences, SWAN improves detection of arterial thrombus. • Multiplanar SWAN analysis had the best diagnostic performance for arterial thrombus detection. • Sensitivity was 96% and specificity 100%. • Findings support combination of time-of-flight and susceptibility effects in suspected acute stroke.

Clinical Trial
Thoracic outlet syndrome in 3T MR neurography-fibrous bands causing discernible lesions of the lower brachial plexus.
To investigate whether targeted magnetic resonance neurography (MRN) of the brachial plexus can visualise fibrous bands compressing the brachial plexus and directly detect injury in plexus nerve fascicles. ⋯ • MR neurography (MRN) can aid the diagnosis of thoracic outlet syndrome (TOS). • Identifiable causes of TOS in MRN include fibrous bands and bony anomalies. • Increased T2W signal within brachial plexus elements indicate relevant nerve compression. • High positive predictive value allows confident and targeted indication for surgery.

In mass casualty incidents (MCI) a large number of patients need to be evaluated and treated fast. Well-designed radiological guidelines can save lives. The purpose of this study was to evaluate the Advanced Trauma Life Support (ATLS) radiological guidelines in the MCI of an aeroplane crash. ⋯ • Radiological imaging protocols can assist the management of mass casualty incidents needs. • Advanced Trauma Life Support (ATLS) radiological guidelines have been developed. • But radiological guidelines have not frequently been applied in aeroplane crashes. • Aircraft accidents are of high energy so ATLS guidelines should be applied. • Following mass casualty incidents total body CT seems appropriate within ATLS protocols.
