To evaluate the characteristics of sigmoid plate dehiscence (SPD) causing pulsatile tinnitus (PT) on CT arteriography and venography (CTA + V). ⋯ Pulsatile tinnitus (PT) caused by sigmoid plate dehiscence (SPD) may be cured. SPD causing PT has some characteristic findings on CT. SPD may be a common key to triggering PT's perception. Thin-slice high resolution CT venography is recommended for SPD assessment. The relationship between intracranial pressure and SPD causing PT should be studied.

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.

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 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.
