Comparative Study
Diffusion-weighted MR imaging in comparison to integrated [¹⁸F]-FDG PET/CT for N-staging in patients with lung cancer.
The purpose of this study was to prospectively determine the diagnostic accuracy of diffusion-weighted imaging (DWI) using MRI in the staging of thoracic lymph nodes in patients with lung cancer, and to compare the performance to that of PET/CT. ⋯ Diffusion-weighted imaging does not show a clear advantage over conventional MR protocols in the N-staging of lung cancer. MRI with or without DWI shows a moderately correlation with PET/CT with a tendency for understaging.

The accuracy of diagnosis of intracranial aneurysms by subtraction computed tomography angiography (CTA) was compared with conventional non-subtracted CTA and with digital subtraction angiography (DSA). ⋯ Conventional CTA has lower sensitivity for the detection of very small aneurysms and aneurysms adjacent to the skull when compared to subtraction CTA. Subtraction CTA performed on a 320-detector row volume CT is an accurate diagnostic tool that provides data equivalent to that obtained with three-dimensional-DSA for the detection of intracranial aneurysms.

To prospectively analyze different FDG-PET/CT-parameters (modified RECIST, SUVmax, TLG, PETvol) in patients with malignant pleural mesothelioma (MPM) under continued pemetrexed and platin based treatment. ⋯ Permetrexed and platin based treatment in MPM patients can be given over a prolonged time with good tolerance. Therapy response should be assessed by modRECIST in CT but not with SUVmax in FDG-PET. Long term permetrexed and platin therapy should be considered in MPM patients with good tolerance of treatment and ongoing morphological response in CT.

Comparative Study
Femoroacetabular cam-type impingement: diagnostic sensitivity and specificity of radiographic views compared to radial MRI.
To retrospectively assess the diagnostic sensitivity of 45° Dunn view and cross-table lateral radiographs for the assessment of cam deformity by comparison with radial MRI. ⋯ The 45° Dunn view can improve the first line of impingement diagnostics. Radial MRI however remains indispensable for pre-operative planning and the evaluation of symptomatic cases without obvious deformity.

Case Reports
Transarterial Onyx packing of the transverse-sigmoid sinus for dural arteriovenous fistulas.
To report transarterial Onyx packing of the transverse-sigmoid sinus for dural arteriovenous fistulae (DAVFs). ⋯ Transarterial Onyx packing of transverse-sigmoid sinus for DAVFs via the meningeal arterial system is a safe therapeutic alternative in selected cases.
