To evaluate the subjective and objective qualities of computed tomography (CT) venography images at 80 kVp using model-based iterative reconstruction (MBIR) and to compare these with those of filtered back projection (FBP) and adaptive statistical iterative reconstruction (ASIR) using the same CT data sets. ⋯ • MBIR provides superior image quality compared with FBP and ASIR • CTV at 80kVp with MBIR improves diagnostic confidence in diagnosing DVT • CTV at 80kVp with MBIR presents better image quality with low radiation.

Our goal is to present our multi-year experience in incident reporting in CT in a large medical centre. ⋯ • Total safety incident report rate in CT is 0.22 %. • Adverse drug reaction is the most common safety incident in CT. • Medication/IV safety is the second most common safety incident in CT.

To investigate the natural course of persistent pulmonary subsolid nodules (SSNs) with solid portions ≤5 mm and the clinico-radiological features that influence interval growth over follow-ups. ⋯ • Pure GGNs ≥10 mm have significantly more frequent interval growth than those <10 mm. • Part-solid GGNs ≥8 mm have significantly more frequent interval growth than those <8 mm. • Management of SSNs with solid portions ≤5 mm can be subdivided by diameter.

To determine the different imaging features of intrahepatic mass-forming cholangiocarcinoma (IMCC) from hepatocellular carcinoma (HCC) on gadoxetic acid-enhanced magnetic resonance imaging (MRI). ⋯ • Analysis of enhancement characteristics helped accurate discrimination of IMCCs from HCCs. • Wash-out should be determined on the PVP of gadoxetic acid-enhanced MRI. • A hypointense rim on the HBP was a significant finding of IMCCs.

To analyse predictors for short- and long-term renal function changes after fenestrated and branched endovascular aortic repair (EVAR). ⋯ • Longer procedure time is associated with an increased risk for AKI. • Renal perfusion defects on angiography are associated with increased risk for AKI. • Post-EVAR AKI is associated with higher probability for long-term eGFR decrease. • Iodinated contrast volume is not an independent risk factor for AKI. • Iodinated contrast volume is not an independent risk factor for long-term eGFR decrease.
