To report radiologic findings with histopathologic correlations of humidifier disinfectant-associated children's interstitial lung disease (HD-chILD) and to compare computed tomography (CT) findings between survivors and non-survivors. ⋯ Chemical disinfectants can induce severe inhalation lung injury. Lung injury caused by inhaled disinfectants demonstrates chronologic changes in radiologic findings. Understanding of radiological characteristics is important to predict outcomes in chemical pneumonitis. Physicians should be aware of the potential risk of environmental chemicals.

Observational Study
CT Radiogenomic Characterization of EGFR, K-RAS, and ALK Mutations in Non-Small Cell Lung Cancer.
To assess the association between CT features and EGFR, ALK, KRAS mutations in non-small cell lung cancer. ⋯ Air bronchogram, pleural retraction, small size relate to EGFR mutation in NSCLC. Pleural effusion and younger age relate to ALK mutation. Round lesion shape, nodules in non-tumour lobes relate to KRAS mutation.

To investigate the feasibility of ultrashort echo time (UTE) magnetic resonance imaging (MRI) for the diagnosis of skull fractures. ⋯ Despite ionising radiation, CT is standard for skull fracture assessment. Conventional MRI cannot depict skull structures. 3D-UTE sequences clearly demonstrate skull structures and fractures. UTE plus conventional MRI are superior to CT in craniocerebral trauma assessment. Paediatric and pregnant patients will benefit from this imaging modality.

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.
