Comparative Study
Comparison of percutaneous long bone cementoplasty with or without embedding a cement-filled catheter for painful long bone metastases with impending fracture.
To compare the efficacy of percutaneous long bone cementoplasty (PLBC) with and without embedding a cement-filled catheter in the medullary canal (ECFC) for painful long bone metastases with impending fracture. ⋯ • Metastases in long bones may cause pain and subsequent pathological fractures. • Cementoplasty resulted in significant pain relief in patients with long bone metastases. • Combination of PLBC and ECFC may reduce the incidence of fractures.

To evaluate the extracranial venous anatomy with contrast-enhanced MR venogram (CE-MRV) in patients without multiple sclerosis (MS), and assess the prevalence of various venous anomalies such as asymmetry and stenosis in this population. ⋯ • The venous anatomy of the neck in patients without MS demonstrates multiple variants • Asymmetry and stenoses of the internal jugular veins are common • Collateral neck veins are not uncommon in patients without MS • These findings do not support the theory of chronic cerebrospinal venous insufficiency • MR venography is a useful imaging modality for assessing venous anatomy.

Observational Study
Assessment of ventriculo-vascular properties in repaired coarctation using cardiac magnetic resonance-derived aortic, left atrial and left ventricular strain.
In patients with repaired coarctation of aorta (CoA), we assessed ventriculo-vascular characteristics using CMR-derived aortic area strain (AAS), left atrial (LA) and left ventricular (LV) longitudinal and circumferential strain (LS, CS). ⋯ • Impaired arterial strain is a measure of increased stiffness in arteries • Ascending aorta strain correlates with left ventricular mass and longitudinal strain • Ascending aorta strain is significantly lower in hypertensive coarctation patients • Hypertension may be a consequence of vascular pathology persisting despite repair.

The vast majority of superior vena cava (SVC) syndromes are of malignant causes, but with growing use of indwelling central catheters and implanted cardiac devices, benign SVC syndromes are becoming more frequent. The main objective of this study is to evaluate long term outcome in patients treated for benign SVC syndrome by endovascular techniques. ⋯ • Malposition of indwelling central catheter can cause superior vena cava obstruction. • Image-guided catheter placement helps prevent superior vena cava obstruction. • Imaging and superior vena cava obstruction classification allows adequate procedure planning. • Endovascular techniques are safe and effective for superior vena cava syndrome treatment.

To evaluate the clinical implications of lymph node (LN) density on 18F-FDG PET/CT for mediastinal LN characterization in non-small cell lung cancer (NSCLC). ⋯ • SUVmax showed the highest diagnostic ability for detecting malignant LNs. • LN density was useful in characterization of LNs with mild FDG uptake. • SUVmax and LN density together could stratify the risk of LN metastasis.
