To assess whether conventional magnetic resonance imaging (MRI), diffusion-weighted imaging (DWI), and dynamic susceptibility contrast-enhanced perfusion-weighted imaging (DSC-PWI) could non-invasively predict p53 and Ki-67 labelling index (LI) and O-6-methylguanine-DNA methyltransferase (MGMT) promoter methylation status in adult isocitrate dehydrogenase (IDH) wild-type glioblastomas.
The conventional MRI, DWI, and DSC-PWI results of 120 adult patients with IDH wild-type glioblastomas were reviewed retrospectively and their efficacy was analysed using chi-square tests or Fisher's exact test. Relative minimum apparent diffusion coefficient (rADC
) and relative maximum cerebral blood volume (rCBV
) values were compared between glioblastomas with different molecular statuses using the Mann-Whitney U-test. Receiver operating characteristic (ROC) curves and logistic regression were used to evaluate predictive performance.
Glioblastomas with a high p53 LI were more likely to show a well-defined enhancement margin (p=0.047). Glioblastomas in the high-Ki-67-LI group demonstrated significantly lower rADC
(p<0.001) and higher rCBV
(p=0.001) values than those in the low-Ki-67-LI group. Tumours without MGMT promoter methylation showed lower rADC
(p<0.001) and higher rCBV
(p<0.001) values than those with it. The rCBV
value exhibited a greater efficacy in predicting the MGMT promoter methylation status of adult IDH wild-type glioblastomas than the rADC
value (p=0.001).
The present results suggest that conventional and DWI and DSC-PWI results are influenced by the molecular status of the glioblastoma and indicate that DWI and DSC-PWI may help to identify regions of high invasiveness within heterogeneous glioblastomas.

To evaluate a two-compartment model with a normal and an abnormal compartment using hybrid multidimensional (HM) magnetic resonance imaging (MRI) for detection of early stage degeneration in knee articular cartilage.
Forty mild osteoarthritis (OA; Kellgren-Lawrence grades [KLGs] 1 and 2), 27 moderate OA (KLG 3), and 23 healthy controls were included in the study. HM imaging using a two-compartment model was used to measure a normal and an abnormal cartilage compartment. The relationship between V
and the degree of cartilage degeneration was examined using whole-organ MRI scores (WORMS). Receiver operating characteristic analysis was used to detect the ability of V
, apparent diffusion coefficient (ADC), and T2 relaxation time to discriminate healthy controls from early OA.
The intra- and interobserver reproducibility for calculated mean V
values and WORMS indicated substantial agreement (intraclass correlation coefficient and weighted kappa >0.8). Overall, V
in all compartments significantly differed among the healthy controls (50±5.5%) and mild (41.1±5.3%) and moderate OA (36.4±8.1%). Mean V
correlated negatively with the degree of OA progression (ρ=-0.778, p<0.001). Mean V
was characterised by a higher sensitivity (82.5%, 95% confidence interval [CI=67.2-92.7) and specificity (87%, 95% CI=66.4-97.2), with a cut-off value of 44.4%, compared to ADC and T2 values or a combination of ADC and T2 to differentiate early OA from healthy controls.
HM-MRI coupled with values of ADC and T2 may provide value for detecting cartilage degeneration at an early stage of OA.

To evaluate the efficacy of Focused Assessment with Sonography in Trauma (FAST) in a paediatric population with a substantial proportion of penetrating abdominal injuries.
FAST and computed tomography (CT) abdomen findings were compared for 98 children who presented to Camp Bastion during the war in Afghanistan in 2011. FAST performance was compared to the reference standard of free fluid detected on CT. Whether children presented alone or as part of a group was also ascertained from the radiology database.
Of the 98 patients, 20 had free fluid on CT and 15 were FAST positive. Fourteen of the 98 (14%) had penetrating wounds to the abdominal cavity. For the whole cohort FAST sensitivity was 65% (41-85%) and specificity 97% (91-100%). For those with penetrating abdominal injury sensitivity was 64% (31-89%) and specificity was 100% (40-100%). In total, 45% arrived at the same time as another casualty, and 30% arrived with other injured children.
FAST performance in this population was similar to that reported in the context of paediatric blunt trauma, with high specificity for intra-abdominal free fluid. This is the first time this has been demonstrated in a cohort containing children with penetrating abdominal trauma. A substantial proportion of children presented as part of a group, necessitating simultaneous triage of multiple injured patients. FAST has a role to play in conflict medicine and mass casualty scenarios where rapid access to CT may not be feasible.

To describe a governance framework for setting up an ambulatory care unit in the interventional radiology setting.
Guidance from NHS England, Getting it right first time, The kings fund, NHS modernisation agency, NHS Improvement, The General Medical Council, The Royal college of Radiologists, The British society of interventional radiology, The Care Quality Commission, and the British Association of Day Surgery was reviewed and referenced as evidence for the governance pathway for day-case patients.
A complete pathway for ambulatory care of patients in interventional radiology from referral to discharge is outlined with a discussion of examples of quality and safety.
Successful implementation of an ambulatory care unit in interventional radiology requires a collaborative, multidisciplinary approach that links in with the NHS improvements ethos for more day-case procedures.

To examine the radiological images of children with musculoskeletal injuries and accompanying organ injuries caused by explosions to determine the differences and frequency of injury types and to emphasise the importance of radiology in war injuries.
Seventy-four children with injuries caused by bomb explosions were included in the study. The paediatric trauma scores evaluated in the emergency department on the first admission were recorded. All radiographs and computed tomography (CT) images were evaluated for musculoskeletal injuries and accompanying organ injuries.
The highest incidence of fracture in the primary blast injury (PBI) group was skull fracture in 15 (62.5%) patients (p=0.01) and fractures in the other groups were most common in the lower extremities. Amputation was observed in nine (31%) patients in the PBI group (p=0.003); however, there were no patients with amputations in the secondary blast injury (SBI) group (p=0.002). The frequency of pneumothorax (79.3%) and pulmonary contusion (59.4%) was high in the PBI group (p<0.001 and p=0.004, respectively). Skull fractures were observed in 15 (88.2%) of 17 patients with brain injury (p<0.001), and skull fractures were the most common fracture site accompanying pulmonary trauma. The average paediatric trauma score of individuals exposed to shrapnel was found to be high (p<0.001).
Because paediatric musculoskeletal injuries vary with the type of blast injury and severe trauma can occur in children due to blast effects, radiologists who triage mass injuries should understand the effects of blast injury patterns and the spectrum of injury.

Energy-based devices are surgical devices increasingly utilized for thyroid surgery, owing to a reduction of operative time and surgical related complications. The aim of the study is to evaluate whether the use of energy-based devices could improve the complication rate in pediatric thyroid surgery.
This is a retrospective observational study. We identified 177 consecutive pediatric patients (Group A) with thyroid diseases, surgically treated by energy-based devices and 237 patients (Group B) treated by conventional clamp and tie technique and matched for sex, age and indication for surgery. Transient and permanent complications rate, operative time and length of hospital stay were compared between the two groups.
Patients of Group A experienced a lower complication rate compared to Group B. Particularly, transient (11.3 vs. 19% p<0.05) and permanent post operative hypoparathyroidism (1.7 vs. 5.5%, p<0.05) were lower in Group A. Moreover, operative time was also shorter in Group A compared to Group B and this difference was statistically significant in patients who performed total thyroidectomy alone and total thyroidectomy associated with central compartment neck dissection (p<0.05). Length of hospital stay was lower in Group A than in Group B, but this difference was statistically significant only for microfollicular lesion (p<0.05).
The use of energy-based devices has a key role in reducing surgical related complications, particularly transient and permanent hypoparathyroidism, operative time and length of hospital stay in pediatric patients treated with thyroid surgery.

Retrospective comparative study.
Retrospective comparative study.
Early allograft dysfunction (EAD) had been established as a useful tool to asses graft and patient survival after liver transplant. We wanted to evaluate effect of EAD components on early graft survival.
This retrospective study included 264 patients with EAD after liver transplant in the period between 2015 and 2019. The patients with retransplants were excluded from analyses. The EAD was determined with Olthoff criteria. The logistic regression model was used for analyses. The 90-day graft survival was set as a primary outcome measure.
The main indications for transplant in the analyzed group were hepatitis C virus infection (53 patients, 20.1%), hepatitis B infection (22, 8.3%), primary sclerosing cholangitis (28, 10.1%), and alcoholic liver disease (62, 23.5%), with a median model for end-stage liver disease score of 13.5 points. The 90-day graft loss occurred in 51 patients (19.3%). Each of the components used in EAD diagnosis was found to be correlated with 90-day graft loss.
