Arterial spin labelling (ASL) is a magnetic resonance imaging perfusion technique used to study cerebral blood flow. It differs from magnetic susceptibility-based perfusion sequences in that it does not require contrast media, but rather uses the signals emitted by pre-labelled protons. It is useful in the exploration of several different kinds of neurological pathologies including ischaemic stroke, brain tumours, dementia and epilepsy. However, it presents numerous artifacts that radiologists must be familiar with to ensure a correct interpretation of findings.

Objective
To compare the prognostic impact of the extent of lung disease detected on computed tomography (CT) when assessed visually by an expert radiologist compared to automatically by an artificial intelligence (AI) system in patients with COVID-19 pneumonia.
Material and methods
A retrospective study of patients with clinical suspicion of COVID-19 pneumonia which assessed the extent of lung involvement visually and by AI. Patients were divided into poor (death/ICU) and good (discharge) prognosis groups. Univariate and multivariate analyses (logistic regression) were performed on the variables that demonstrated significant differences between both groups.
Results
Patients with a poor prognosis more frequently had greater lung involvement visually (stages 3–4; 37.5% vs 14.3%; p = 0.001) and by AI (stages 3–4; 35% vs 6.2%; p < 0.001). The radiologist-AI agreement correlation coefficient was excellent (0.905; p < 0.001). High blood pressure (OR 4.26; p < 0.001), alterations in levels of creatinine (OR 5.63; p < 0.001), lactate dehydrogenase (OR 11.69; p < 0.001) and D-dimer (OR 5.68; p < 0.001), and the extent of affected lung parenchyma assessed visually (stage 1vs4 OR 10.36; p = 0.001) and by AI (stage 1vs4 OR 25; p = 0.001) were the variables with the greatest prognostic impact in the univariate analysis. The multivariate analysis models considering the extent assessed visually and by AI did not demonstrate any significant differences (AUC 0.876 vs 0.870; p = 0.278).
Conclusion
The extent of affected lung parenchyma on CT images demonstrates prognostic value both on their own and in conjunction with clinical factors and blood levels in patients with COVID-19 pneumonia. No significant differences were observed between the radiologist's visual estimate and the AI-based automatic detection system used in this study.

Introduction
Scientific journals are a fundamental tool for the dissemination of evidence-based medicine. The scientific quality of a journal is related to the level of evidence of its publications. The aim of our study is to analyse and quantify changes in the levels of evidence assigned to articles published in the Radiología journal over the last six years.
Material and methods
We evaluated articles published in Radiología from 2018 to 2023. A critical reading of the selected articles was carried out and a level of evidence was assigned using two scales that are specific to the field of radiology (Insights into Imaging and the 2011 Oxford Center Evidence Based Medicine). Pearson residuals were used to establish differences in the level of evidence over the years, with a p-value < 0.05 being considered statistically significant. The level of agreement between the two scales for assessing levels of evidence was also compared using the Kappa coefficient.
Results
Of the total 404 publications in Radiología from 2018 to 2023, 275 articles were included for analysis. There was evidence of a progressive increase in the level of evidence for the publications, with a peak in 2023, consistently on both scales (p = 0.043). A Kappa coefficient of 0.92 was obtained in the analysis of agreement between scales (almost perfect agreement).
Conclusion
The level of evidence for publications in the Radiología journal has significantly increased in 2023.

Objective
To evaluate the accuracy of multidetector computed tomography (MDCT) to select patients with peritoneal carcinomatosis (PC) as candidates for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS + HIPEC), through an analysis of the degree of correlation between the radiological (rPCI) and surgical (sPCI) scores in the PC index.
Methods
Observational, retrospective, single-centre study between 1 May 2014 and 31 May 2018. Calculated rPCI assessed by MDCT was compared with the sPCI using the Concordance Correlation Coefficient (CCC). The Bland-Altman method was used to plot the difference between the two observations against their mean with a confidence interval (CI) of 95%. We assessed whether tumour volume affects the CCC by setting a cut-off point of sPCI at 15 and considering a sensitivity and specificity of rPCI > 20 as a predictor of unresectability.
Results
50 patients underwent surgery. Mean sPCI was 11.8 (9.5) and rPCI was 11.0 (10.2), with a CCC of 0.94 (95% CI: 0.91–0.97). The CCC in the 35 patients with sPCI 20 had a sensitivity of 0.82 (95% CI: 0.68–0.92) and a specificity of 0.40 (95% CI: 0.05–0.85). The positive predictive value was 0.92 (95% CI: 0.80–0.98), while the negative predictive value was 0.20 (95% CI: 0.03–0.56).
Conclusion
MDCT, interpreted by an expert radiologist, is reliable for the selection of patients as candidates for CRS + HIPEC; however, the rPCI value cannot be considered in isolation as a contraindication to full treatment. Greater tumour volume usually leads to a worse concordance between rPCI and sPCI.

Valvular heart disease is a condition with increasing prevalence. Although the current treatment of choice is still valve repair or replacement surgery, percutaneous treatment techniques are valid alternatives for selected patients. Various non-invasive imaging techniques are currently available which can provide the information needed to select appropriate patients, planning procedures and techniques.
This article reviews the usefulness of cardiac CT to assess patients who are candidates for percutaneous treatment of common valvular diseases. It also reviews the image acquisition protocol and its role in the pre-procedural study, as well as in the detection of the most common complications.

Bladder cancer is a cause for serious concern due to its high prevalence and the considerable challenges it poses in terms of morbidity, costs, and mortality. In recent years, magnetic resonance imaging (MRI) of the bladder has proved to be a useful tool with a significant impact on both local staging and the assessment of neoadjuvant treatment responses. This article reviews the main anatomical, histological and radiological characteristics of bladder neoplasms, describes bladder MRI, explains the VI-RADS® classification—which should only be used to classify malignant lesions and in studies undertaken principally to evaluate the probability of tumour infiltration in the muscular layer—and specifies how this technique can optimise the clinical management of patients with bladder neoplasms.

Diastematomyelia, a rare congenital anomaly of the spine, is characterised by the division of the spinal cord and is often associated with other spinal and cutaneous malformations. Diagnosis is primarily conducted via prenatal ultrasound and fetal Magnetic Resonance Imaging (MRI). The postnatal evaluation is carried out using Computed Tomography (CT) and MRI, which are essential for comprehensive assessment and therapeutic planning. Prognosis depends on the presence of neurological symptoms, whose severity may correlate with specific radiological findings. Treatment ranges from surgery in symptomatic cases to observation in asymptomatic patients. This article reviews diastematomyelia, providing illustrative images from postnatal CT and MRI to emphasize the importance of comprehensive evaluation in ensuring an accurate diagnosis that guides appropriate clinical management.

Therapeutic ultrasound diathermy is a widely available noninvasive method, used to softening scar tissue, resolving edema, and accelerating wound healing. However, there is no consensus regarding the efficacy of this method and there is a lack of information on specific complications. We report three cases of focal bone lesions time-related with physiotherapy using ultrasound diathermy. The first patient presented with lesions in the medial and lateral portions of the distal metaphysis of the right femur, as well as in the proximal metaphysis of the tibia. The second patient presented with lesions in the left ankle. The third patient presented with lesions in the knee, bilaterally. The lesions were characterized by subcortical linear or arc lesions with hypointense signal on T1-weighted imaging and hyperintense signal on T2- and proton-density weighted imaging, similar to osteonecrosis. However theses lesions were distributed in superficial areas, in which the ultrasound is directly applied. All patients reported improvement or resolution of pain after discontinuation of ultrasound diathermy. Therefore, therapeutic ultrasound diathermy may be associated with focal bone lesions. This diagnosis should be considered when superficial bone lesions appear time-related to therapy and in areas not usually affected by osteonecrosis.
