To estimate the diagnostic accuracy of the Liver Imaging-Reporting and Data System (LI-RADS) with computed tomography (CT) for diagnosing hepatic nodules (10-20 mm) detected in cirrhotic livers. ⋯ LIRADS with CT provides a strong validity for the diagnosis of small hepatic nodules, and is very useful to improve the accuracy of CT reports.
-
To evaluate the diagnostic accuracy achieved from a fat-water Dixon sequence alone compared to a combination of a silicone-specific magnetic resonance imaging (MRI) sequence and a water-specific MRI sequence in the assessment of breast implants. ⋯ A single Dixon sequence allows an accurate diagnostic evaluation of breast implants and concomitant shortening of the overall acquisition time.
-
To determine the threshold waveform characteristics at Doppler ultrasound (DUS) to differentiate between ischaemic and non-ischaemic priapism. ⋯ In the present cohort, PSV <50 cm/s and MV <6.5 cm/s were predictive of ischaemic priapism (pre-shunt; p<0.01). Patients with ischaemic priapism may show PSV >22 cm/s, but have diastolic reversal and therefore low net perfusion. Post-shunt, DUS findings were extremely variable and did not predict histology or clinical outcome.
-
To determine whether the active involvement of radiographers in nasogastric tube (NGT) management at a large multisite healthcare institution can contribute to risk reduction regarding feeding through misplaced NGTs. ⋯ After focused training, radiographer comments are a safe, sustainable, and workable solution offering an effective solution for image misinterpretation issues relating to NGT "never events". This should be considered for wider implementation in healthcare.

To review the radiology-led ultrasound (US) surveillance programme for the detection of hepatocellular carcinoma (HCC) in cirrhotic patients in a UK tertiary-referral centre. ⋯ Even with a radiology-led recall service for HCC surveillance, the proportion of patients receiving scans 6-monthly was low, due in part to the lack of organisational support that is available for other screening programmes. This study gives a realistic representation of the implementation of surveillance in a UK hospital at the current time and of the rates of HCC proceeding to treatment.
