Comparative Study
Correlation study of 3T-MR-DTI measurements and clinical symptoms of cervical spondylotic myelopathy.
To discuss the correlation between diffusion tensor imaging (DTI) measurements, diffusion tensor tractography and the clinical symptoms of cervical spondylotic myelopathy. ⋯ The FA values and the change patterns of fiber bundle were more sensitive than T2WI for spinal cord lesion, and were positively correlated with clinical symptoms.

The difference in arterial supply, venous drainage, functional localization in supratentorial and infratentorial compartments may contribute to the conflicting results about risk factors for hemorrhage in published case series of brain arteriovenous malformation (bAVM). Further investigation focused on an individual brain compartment is thus necessary. This retrospective study aims to identify angioarchitectural characteristics associated with the initial hemorrhagic event of supratentorial bAVMs. ⋯ Supratentorial bAVMs with perforating feeders and deep venous drainage have a higher risk of hemorrhage. In contrast with many previous reports, AVM location was not associated with hemorrhagic presentation in adjusted analyses. The correlation between deep location and initial hemorrhage in univariate analysis might be caused by the involved perforating feeders and deep draining vein in the deep located AVMs.

Autosomal dominant polycystic kidney disease (ADPKD) patients have an increased risk for intracranial aneurysms (IAs). Our aim was to screen and follow up the unruptured intracranial aneurysms (UIAs) detected by 3.0 T three-dimensional time-of-flight magnetic resonance angiography (3D-TOF MRA) in patients with ADPKD in order to evaluate the growth of UIAs and the value of 3D-TOF MRA. ⋯ 3.0 T 3D-TOF MRA was feasible for UIAs follow-up in ADPKD patients. The chance of enlargement and rupture of UIAs in ADPKD patients was not higher than in the general population.

The purpose of this study was to compare diagnostic capabilities for assessment of recurrence in non-small cell lung cancer (NSCLC) patients by contrast-enhanced whole-body MRI (CE-WB-MRI) with and without CE-Quick 3D and double RF fat suppression technique (DFS), FDG-PET/CT and conventional radiological examinations. ⋯ Specificity and accuracy of CE-WB-MRI with CE-Quick 3D and DFS for assessment of recurrence in NSCLC patients are at least as high as, or higher than those of others.

Comparative Study
Comparison of PET-CT and magnetic resonance diffusion weighted imaging with body suppression (DWIBS) for initial staging of malignant lymphomas.
To evaluate the clinical impact of diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) in staging of malignant lymphoma. ⋯ For malignant lymphoma in a pre-therapeutic context, agreement between diffusion-weighted whole-body imaging and PET/CT is high for Ann Arbor staging.
