To evaluate the efficacy and safety of percutaneous microwave ablation (MWA) in patients with larger hepatocellular carcinoma (HCC) tumours. ⋯ Percutaneous MWA is effective and safe for treating larger HCC tumours. The local tumour control and long-term survival are acceptable.
-
To review whole-body computed tomography (CT) angiography as an unmatched way of fully assessing battle-injured patients, and the prevalence of vascular, predominantly arterial, injuries identified. ⋯ A significant proportion of occult vascular injuries occur in penetrating fragmentation and blast injuries in military trauma. A low threshold for single-pass whole-body CT angiography is therefore justified.

Radiologists frequently encounter studies demonstrating spinal instrumentation, either as part of the patient's postoperative evaluation, or as incidental to a study performed for another purpose. It is important for the reporting radiologist to identify potential complications of commonly used spinal implants. Part 1 of this review examined both the surgical approaches used and the normal appearances of these spinal implants and bone grafting techniques. This second part of the review will focus on the multimodal imaging strategy adopted in the assessment of the instrumented spine and the demonstration of imaging findings of common postoperative complications.

The general radiologist frequently encounters studies demonstrating spinal instrumentation, either as part of the patient's postoperative evaluation or as incidental to a study performed for another purpose. There are various surgical approaches and devices used in spinal surgery with an increased understanding of spinal and spinal implant biomechanics drives development of modern fixation devices. ⋯ The aim of part 1 of this review is to familiarize the reader with terms used to describe surgical approaches to the spine, review the function and normal appearances of commonly used instrumentations, and understand the importance of the different fixation techniques. The second part of this review will concentrate on the roles that the different imaging techniques play in assessing the instrumented spine and the recognition of complications that can potentially occur.

Comparative Study
320-detector row CT angiography for detection and evaluation of intracranial aneurysms: comparison with conventional digital subtraction angiography.
To compare the diagnostic performance of 320-detector row computed tomographic angiography (CTA) with digital subtraction angiography (DSA) for the detection and characterization of intracranial aneurysms. ⋯ 3D CTA is a highly sensitive, specific, and non-invasive imaging method for diagnosis and evaluation of intracranial aneurysms. It also allows for precise depiction of aneurysm morphology. Therefore, 320-detector row CTA may be used as an alternative to DSA as a first-line imaging technique in patients with SAH.
