To retrospectively evaluate the safety and efficacy of CT-guided percutaneous microwave ablation (MWA) of small-sized (≤2 cm) hepatocellular carcinoma (HCC) regarding therapy response and survival rates. The goal is to compare data from minimal invasive treatments like MWA and radiofrequency ablation in comparison to surgical resection or data from liver transplantation.

The high incidence of bone metastases, particularly vertebral metastases, in patients with cancer and the limitations of conventional treatments are the main challenge for the interventional oncology specialty.

Vacuum-assisted biopsy (VAB) is performed when a breast lesion appears suspicious at imaging examinations. Although several different modalities can guide the biopsy, some lesions can only be visualised by imaging modalities that can depict tumour neo-angiogenesis. For this type of lesion, MRI is the most sensitive modality when lesions are occult at second-look ultrasound or mammography.

Dynamic myocardial CT perfusion (CTP) is a relatively novel technique that can depict myocardial ischaemia. However, the radiation dose required for dynamic CTP remains relatively high. Therefore, the authors investigated the feasibility of dose reduction in dynamic myocardial CTP by comparing the diagnostic performance resulting from acquiring images during all heartbeats to that involving the periodic skipping of imaging during a certain proportion of heartbeats.

Treatment of cerebral aneurysms using haemodynamic implants such as endosaccular flow disruptors and endoluminal flow diverters has gained significant momentum during recent years. The intended target zone of these devices is the immediate interface between the aneurysm and the parent vessel. The therapeutic success is based on the reduction of aneurysmal perfusion and the subsequent formation of a neointima along the surface of the implant.

Cardiac MRI provides a wealth of information for diagnosis and serial management of patients with cardiovascular disease, particularly therapeutic drug toxicity, amyloidosis, myocardial fibrosis, and oedema.
