Observational Study
Incidence of contrast-induced nephropathy in hospitalised patients with cancer.
To determine the frequency of and possible factors related to contrast-induced nephropathy (CIN) in hospitalised patients with cancer. ⋯ • Contrast-induced nephropathy (CIN) is a concern for oncological patients undergoing CT. • CIN occurs more often when CT is performed <45 days after chemotherapy. • Hypertension and treatment with bevacizumab appear to be additional risk factors.

Randomized Controlled Trial Multicenter Study
Whole-body diffusion-weighted imaging: is it all we need for detecting metastases in melanoma patients?
To investigate whether whole-body diffusion-weighted imaging (WB-DWI) alone is adequate for detecting metastases in melanoma patients, or if standard WB contrast-enhanced magnetic resonance imaging (WB-ceMRI) is required. ⋯ WB-DWI without additional WB-ceMRI sequences is promising for the detection of extracranial metastases in melanoma patients, but contrast-enhanced MRI is required for evaluating the brain.

To evaluate DW MR tumour volumetry and post-CRT ADC in rectal cancer as predicting factors of CR using high b values to eliminate perfusion effects. ⋯ DW MR tumour volumetry after CRT showed significant superiority in predicting CR compared with T2-weighted MR images and post-CRT ADC.

To evaluate the accuracy, safety and efficacy of magnetic resonance imaging (MRI)-guided facet joint injection therapy using a 1.0-T open MRI. ⋯ MR-guided facet joint injection therapy of the lumbosacral spine is accurate, safe and efficient in the symptomatic treatment of lower back pain.

Computed tomography (CT)-defined anatomical differentiation of minor and major blunt traumatic aortic injuries (TAIs) was applied to determine injury grade and management/outcomes in minor TAIs, and if the presence of peri-aortic mediastinal haematoma (MH) correlated with TAI grade. ⋯ • MDCT can differentiate minor from major blunt traumatic aortic injuries. • About one-third of MDCT-diagnosed blunt traumatic aortic injuries are minor. • Minor aortic injuries are not necessarily accompanied by mediastinal haemorrhage. • MDCT diagnosis of minor aortic injury supports application of medical management.
