CASE REPORT A 40-year-old woman with good past health presented with a 2-week history of repeated vomiting. Abdominal radiograph revealed multiple dilated large bowel loops. Urgent computed tomography of the abdomen and pelvis revealed a circumferential colonic tumour at the splenic flexure causing upstream bowel dilatation (Figure 1) and a solid peritoneal nodule suspicious of metastasis (Figure 2). An enhancing irregular left breast mass with spiculated margin, invading the underlying pectoralis major muscle, was noted incidentally on the computed tomography scan (Figure 3). The patient subsequently underwent emergency surgery that revealed an obstructing circumferential tumour at the splenic flexure of the colon and multiple small peritoneal nodules. Extended right hemicolectomy was performed.

An empirical fasting period of at least 4 hours prior to intravenous contrast administration for computed tomography scans has been an age-old practice. This is associated with patient discomfort, adverse effects on diabetic control, and limits the flexibility of scanning arrangements in urgent settings. The effect is further compounded by the rising number of urgent imaging requests with some patients requiring repeated fasting while waiting for scanning slots. International guidelines have been recently updated, stating that with the improved safety profile of contrast media, fasting is no longer routinely required. In this article, we discuss the current evidence and its implications for our local practice. We share our approach of a stepwise policy change with eventual full implementation of non-fasting policy to all eligible patients in our institution, and the safety data we compiled. Adoption of a non-fasting policy for contrast-enhanced computed tomography is a feasible and beneficial practice adhering to international standards.

Introduction: Despite several retrospective studies showing the safety and efficacy of transradial access (TRA) for a variety of neurointerventions, the evidence in Asian populations is limited. The smaller size of the radial artery in Asians could cause technical difficulty in access as well as access site complications. This study aimed to assess the feasibility and safety of TRA for neurointervention in an Asian population. Methods: We performed a retrospective review of neurointerventions performed with TRA in our hospital between January 2018 and June 2021. Technical success was defined as TRA with insertion of the sheath and completion of the intervention without crossover to conventional transfemoral access (TFA). The primary endpoint was the in-hospital stay plus the 30-day incidence of access site haematoma requiring surgical treatment or transfusion, symptomatic radial artery occlusion, hand ischaemia, arteriovenous fistula, pseudoaneurysm, and wound infection. The secondary endpoints were procedure-related complications including intra-operative vessel injury, cerebral thromboembolism, and haemorrhagic complications. Results: A total of 45 patients underwent neurointerventions (transcatheter embolisation of aneurysms/arteriovenous malformations/tumours, and extracranial carotid stenting) via TRA. The technical success rate was 93.3%. There were no significant access site complications. The overall procedure-related complication rate was 11.1%. Conclusion: In an Asian population, neurointervention via TRA is feasible, with a low crossover rate and low incidence of access site complications. In this case series, there was no increase in the procedure-related complication rate when compared with TFA.

Introduction: This research aims to evaluate accuracy and interobserver agreement on the correlation between the Prostate Imaging Reporting and Data System version 2.1 (PI-RADS v2.1) and the International Society of Urological Pathology (ISUP) scores. Methods: We examined patients who underwent prostate multiparametric magnetic resonance imaging (MpMRI) prior to transrectal ultrasound–guided cognitive fusion biopsy between April and December 2019. MpMRI examinations were evaluated by two radiologists according to PI-RADS v2.1. Interobserver agreement was recorded and the final PI-RADS category was decided by consensus. The correlation of cognitive fusion biopsy results with PI-RADS v2.1 score was evaluated. Lesions with Gleason score ≥7 were considered to be clinically significant prostate cancer. Results: A total of 84 patients with 106 lesions were included in the study. The rates of prostate cancer in the PI-RADS groups 1, 2, 3, 4, and 5 were 0%, 0%, 22.2%, 56%, and 94.45%, respectively. There was a positive correlation with an area under the curve value of 0.814 between the PI-RADS v2.1 and the ISUP score. Using PI-RADS ≥3 as the cut-off value in the peripheral zone (PZ) and the whole gland, the negative predictive value for malignancy was 100%. For PI-RADS ≥4, it was 76.47% for PZ and 80.65% for the whole gland. Without applying cut-off values, the interobserver agreement for PI-RADS score was κ = 0.562. Conclusion: Our data support the notion that PI-RADS v2.1 facilitates the evaluation of MpMRI and improves interobserver agreement.
