The aim of this study is to evaluate the value of the apparent diffusion coefficient (ADC) obtained in diffusion-weighted (DW) MR sequences for the differentiation between malignant and benign bone marrow lesions. ⋯ ADC values are a useful complementary tool to characterize bone marrow lesions, in order to distinguish acute benign fractures from malignant or infectious bone lesions. However, ADC values are not valuable in order to differentiate malignancy from infection.

Review Meta Analysis
Multi-detector row CT angiography in the assessment of coronary in-stent restenosis: a systematic review.
The aim of this study was to perform a systematic review of the diagnostic accuracy of multi-detector row computed tomography angiography (MDCT) for detection of coronary in-stent restenosis in patients treated with coronary stenting when compared to invasive catheter angiography. ⋯ The results showed that MDCT angiography (with 16 or more detector rows) has moderate sensitivity and high specificity for the detection of coronary in-stent restenosis when compared to invasive catheter angiography. A high specificity value of MDCT may be most valuable as a non-invasive technique of excluding coronary stent restenosis or occlusion. The main factors affecting visualization are stent diameters and stent materials.

To assess the feasibility and utility of high-resolution three-dimensional magnetic resonance angiography (3D MRA) and contrast-enhanced 3D spoiled gradient-recalled imaging (3D SPGRI) for the purpose of visualization of neurovascular contact in trigeminal neuralgia (TN) patients. ⋯ The combined use of high-resolution 3D MRA and contrast-enhanced 3D SPGRI is an extremely sensitive and specific technique for demonstrating vascular contact with the trigeminal nerve in TN patients.

To evaluate peri-procedural, early and late complications as well as patients' acceptance of combined ultrasound and fluoroscopy guided radiological port catheter implantation. ⋯ Combined ultrasound and fluoroscopy guided port catheter implantation is a very safe and reliable procedure with low peri-procedural, early and late complication rate. The intervention achieves very high acceptance by the patients and their relatives.

Controlled Clinical Trial
Post-treatment complications of soft tissue tumours.
To identify local and distant complications of patients with soft tissue tumours and evaluate their relationships to types of therapy. ⋯ This study suggests a possible relationship between types of treatment of soft tissue tumours and subsequent complications. Postoperative radiotherapy was associated with a significant number of patients with seromas, muscle, cutaneous and subcutaneous inflammation, and fractures. Incomplete or difficult surgery resulted in residual or recurrent tumours and heterotopic ossification. Muscle atrophy and nerve entrapment were related to both treatments (resection alone or radiotherapy after resection). Diligent follow-up of patients with soft tissue tumours with recognition of these complications and their differentiation from recurrent or residual tumour can help guide clinical care and may negate the need for surgery when benign disease is defined.
