We hypothesized that three-dimensional pseudocontinuous arterial spin labelling (pCASL) may have similar efficacy in astrocytic tumour grading as dynamic susceptibility contrast-enhanced perfusion-weighted imaging (DSC-PWI), and the grading accuracy may be further improved when combined with apparent diffusion coefficient (ADC) values. ⋯ • pCASL shows positive correlation with DSC-PWI in astrocytic tumour grading. • ADC values based on ADC histograms can be an objective method. • Combination of DWI and pCASL or DSC-PWI can improve grading accuracy.

To introduce a modified transjugular intrahepatic portosystemic shunt (TIPS) procedure, percutaneous transhepatic balloon-assisted TIPS (BA-TIPS), and to evaluate its feasibility and efficacy in patients with chronic totally occluded portal vein thrombosis (CTO-PVT) with symptomatic portal hypertension. ⋯ • Transjugular intrahepatic portosystemic shunt is an important treatment for portal vein thrombosis (PVT). • TIPS is challenging for patients with chronic totally occluded portal vein thrombosis (CTO-PVT). • The use of a balloon increased the technical success of portal puncture. • Balloon-assisted TIPS (BA-TIPS) is feasible, safe, and effective for CTO-PVT.

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.

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.
