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.

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.

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.

To assess the accuracy and risk factors for complications of computed tomography (CT)-guided percutaneous core needle biopsy (CNB) for small (≤20 mm) pulmonary lesions. ⋯ CT-guided percutaneous CNB of small (≤20 mm) pulmonary lesions provides high diagnostic accuracy with acceptable complications. A lesion-pleural distance of ≥21 mm and needle-pleural angle of ≥51° are identified as the risk factors for highest pneumothorax rate. In addition, the needle-pleural angle is a novel predictor of pneumothorax. A lesion-pleural distance of ≥21 mm is also identified as a risk factor for the highest bleeding rate.

To evaluate the feasibility and efficacy of routine uterine artery embolization (UAE) immediately after planned caesareans performed in the cath lab for conservative treatment of placenta accreta. ⋯ UAE immediately after a caesarean performed in the cath lab is a feasible therapeutic option for conservative treatment of placenta accreta. Advantages include reducing stress and risks associated with transferring women with potentially unstable haemodynamics.
