To compare F-18-fluorodeoxyglucose (FDG) and F-18-fluorothymidine (FLT) PET/CT examinations for differentiating between benign and malignant adrenal tumours. ⋯ • All FDG indices were significantly higher in malignant than in benign tumours. • All FLT indices were significantly higher in malignant than in benign tumours. • All FLT indices were significantly higher than those of FDG in AUC.

Observational Study
Value of CT to predict surgically important bowel and/or mesenteric injury in blunt trauma: performance of a preliminary scoring system.
To evaluate the performance of a computed tomography (CT) diagnostic score to predict surgical treatment for blunt bowel and/or mesentery injury (BBMI) in consecutive abdominal trauma. ⋯ • Finding of bowel wall discontinuity or mesenteric pneumoperitoneum indicates BBMI requiring surgery. • Arterial mesenteric vessel extravasation requires surgery when in association with other CT findings. • Our CT scoring system has excellent diagnostic performance in predicting BBMI requiring surgery.

To compare the worsening of structural lung disease on high-resolution computed tomography (HRCT) with changes in spirometry results in cystic fibrosis (CF) patients, and analyse factors associated with the worsening of structural lung disease over time. ⋯ • HRCT Bhalla scoring changes significantly over 4 years, spirometry results do not. • Females experience faster respiratory deterioration than males. • Spirometry results are not associated with deterioration in HRCT.
-
To investigate long-term pain reduction and 'improvement' in patients with indirect cervical nerve-root-blocks in comparison to MRI findings. ⋯ • Good long term outcomes after indirect nerve root infiltrations with non-particulate steroids. • The presence of nerve root compression was a predictive finding of 'improvement'. • Significantly less patients subsequently having surgery had lower NRS scores 1-month post injection. • There is less pain relief in patients with disc extrusions. • There are less improvement in patients with modic type I changes.

Comparative Study
Interest of HYPR flow dynamic MRA for characterization of cerebral arteriovenous malformations: comparison with TRICKS MRA and catheter DSA.
HYPR flow is a 3D dynamic contrast-enhanced MRA technique providing isotropic sub-millimetre resolution with half-second temporal resolution. We compared HYPR flow and time-resolved imaging of contrast kinetics (TRICKS) MRA for the characterization of cerebral arteriovenous malformations (cAVMs), using catheter DSA as reference. ⋯ • Dynamic MRA is used for cerebral AVM depiction and follow-up • HYPR flow is a new, highly-resolved dynamic MRA sequence • HYPR flow provides whole brain coverage • HYPR flow provides excellent agreement with the Spetzler-Martin grade • Compared to TRICKS MRA, HYPR flow improves cerebral AVM characterization.
