Revolutionizing Intracranial Hemorrhage Diagnosis: A Retrospective Analytical Study of Viz.ai ICH for Enhanced Diagnostic Accuracy.

Introduction Artificial intelligence (AI) alerts the radiologist to the presence of intracranial hemorrhage (ICH) as fast as 1-2 minutes from scan completion, leading to faster diagnosis and treatment. We wanted to validate a new AI application called Viz.ai ICH to improve the diagnosis of suspected ICH. Methods We performed a retrospective analysis of 4,203 consecutive non-contrast brain computed tomography (CT) reports in a single institution between September 1, 2021, and January 31, 2022. The reports were made by neuroradiologists who reviewed each case for the presence of ICH. Reports and identified cases with positive findings for ICH were reviewed. Positive cases were categorized based on subtype, timing, and size/volume. Viz.ai ICH output was reviewed for positive cases. This AI model was validated by assessing its performance with Viz.ai ICH as the index test compared to the neuroradiologists' interpretation as the gold standard. Results According to neuroradiologists, 9.2% of non-contrast brain CT reports were positive for ICH. The sensitivity of Viz.ai ICH was 85%, specificity was 98%, positive predictive value was 81%, and negative predictive value was 99%. Subgroup analysis was performed based on intraparenchymal, subarachnoid, subdural, and intraventricular subtypes. Sensitivities were 94%, 79%, 83%, and 44%, respectively. Further stratification revealed sensitivity improves with higher acuity and volume/size across subtypes. Conclusion Our analysis indicates that AI can accurately detect ICH's presence, particularly for large-volume/large-size ICH. The paper introduces a novel AI model for detecting ICH. This advancement contributes to the field by revolutionizing ICH detection and improving patient outcomes.

A 13-year-old soccer player presenting with a Morel-Lavallee lesion of the knee: A case report and review of literature.

Morel-Lavallee lesions are uncommon injuries and there is a lack of data to support what the most effective management is. In the case of a young athlete with a small lesion, we propose that conservative treatment with rest and close follow up is appropriate.

Aortic Aneurysm Mimicking Inferior ST-Elevation Myocardial Infarction: A Case Report.

Here, we report a rare case of a 22-year-old female presenting with recurrent chest pain mimicking inferior ST-elevation myocardial infarction (STEMI) but ultimately attributed to an aortic aneurysm. Despite facing initial challenges in diagnosis, such as normal troponin levels and temporary electrocardiogram (ECG) changes, advanced imaging showed a large mass in the chest pressing on the right coronary artery. Prompt multidisciplinary intervention, including surgical resection of the aneurysm, led to successful management and improved outcomes. This case highlights the importance of considering unusual etiologies in atypical presentations of myocardial infarction, necessitating comprehensive evaluation and collaboration among various specialties for optimal patient care.

Unusual manifestations of Takayasu arteritis: A diagnostic challenge.

Key Clinical Message: Timely recognition of atypical Takayasu arteritis is crucial. Unusual presentations, such as pericardial effusion, can complicate diagnosis. CT angiogram aids in precise diagnosis, guiding targeted immunosuppressive therapy. Multidisciplinary collaboration is vital for comprehensive management, improving patient outcomes in this challenging condition. Abstract: This case study highlights the diagnostic challenges posed by atypical presentations of Takayasu arteritis (TA), focusing on a 42-year-old male presenting with pericardial effusion. Despite inconclusive initial investigations, a CT angiogram revealed large vessel vasculitis, confirming TA. Management with immunosuppressive therapy led to clinical improvement. This case emphasize the importance of recognizing unusual manifestations of TA for timely diagnosis and appropriate treatment, emphasizing the role of multidisciplinary collaboration in optimizing patient outcomes.

Area postrema syndrome: Intractable hiccups and vomiting as a result of neuromyelitis Optica Spectrum disorder.

A 31 year old woman was referred to the medical team for further investigation of intractable hiccups and vomiting. Initial investigations including blood tests, endoscopy and CT imaging did not identify any cause of symptoms. Following multidisciplinary team review, serial MRI Head imaging was arranged, which revealed progressive posterior fossa signal abnormality with involvement of the area postrema. In combination with a positive serum Aquaporin-4 antibody result, this helped establish a diagnosis of Neuromyelitis Optica Spectrum Disorder (NMOSD). Treatment included high dose steroids, plasma exchange and immunomodulatory therapy, and led to a marked improvement in symptoms. This case highlights the importance of utilising specialty team input and broadening lines of investigation, when managing patients with intractable hiccups and vomiting in whom an initial workup has not established a clear diagnosis. While NMOSD is rare, early identification can inform treatment strategies that may lead to a significant improvement in clinical outcome.

Pneumomediastinum and subcutaneous emphysema post cocaine and amphetamine insufflation.

A 20-year-old gentleman presented with blood-streaked vomitus after insufflation of an unknown amount of powder cocaine and amphetamine. This was taken with an unspecified amount of alcohol. Other notable symptoms were dysphagia, chest pain, palpitations and the patient reported a 'crunchy' sensation in his chest. A chest x-ray revealed pneumomediastinum and a computerised tomography (CT) trauma confirmed these findings with associated subcutaneous emphysema without an identifiable cause. Follow up investigations included a barium swallow and gastroscopy which showed no obvious perforation but mild gastritis and duodenitis. He was managed conservatively with proton pump inhibitor cover and his symptoms resolved.

The COVID-19 pandemic impact on gross income and utilization of radiologic services in a Philippine COVID-19 public tertiary referral hospital

Background@#The global economy has been severely affected by the COVID-19 pandemic which proved to be more than a public health crisis. Volume and gross income have also declined in the health service sector including the diagnostic imaging and radiotherapy divisions of the radiology departments in other countries. @*Objective@#This study determined the change in volume and gross income of the Radiology Department of a tertiary hospital which was designated as a COVID-19 referral center in the Philippines.@*Methodology@#Monthly records of the profit centers of the Radiology Department were reviewed noting the volume and gross income one year before and during the first year of the pandemic. @*Results@#Records were successfully retrieved for the volume of procedures and revenue for each profit center from one year before the pandemic (from March 1, 2019 to February 28, 2020) and the first year of the pandemic (from March 1, 2020 to February 28, 2021). There was a total reduction of 120,046 procedures conducted and Php 84,837,614.16 in revenues generated between the two periods. This is equivalent to a 61.98% (range: 47.92% to 83.37%) decrease in the volume of procedures and a 45.02% (range: 31.08% to 77.86%) decrease in revenue. These changes were found to be statistically significant.@*Conclusion@#The COVID-19 pandemic caused a decline of all profit centers in the Radiology Department. The decline was associated with changes in quarantine restrictions. Data from this study may help the administration of the institution or other institutions to conduct their own studies and cope with future pandemics of similar magnitude or further surges of the current pandemic on decisions regarding budget and resource allocation.

Myositis ossificans in the diabetic foot: a review of the literature with an illustrative case series.

OBJECTIVE: Myositis ossificans is a rare non-neoplastic form of heterotopic ossification most commonly described after trauma or surgery, in the diabetic foot. DESIGN: We provide a review of the literature including three illustrative cases. PARTICIPANTS: Individuals presenting to the foot clinic. SETTING: Single centre, tertiary multidisciplinary specialist diabetes foot clinic. RESULTS: We review the literature surrounding Myositis ossificans, and describe three cases of Myositis ossificans following foot surgery in people with diabetes. All of the imaging was consistent with the descriptions of Myositis ossificans reported elsewhere in large muscle groups. These are the first reports of Myositis ossificans occurring in the feet of people with diabetes. CONCLUSIONS: Myositis ossificans has only very rarely been described in the foot and, as far as we are aware, never in people with diabetes. Given that the prevalence of diabetes is increasing, and the foot problems requiring surgery are also rising, we suggest that clinicians should be more aware of this condition because it may occur more frequently.

A hospital-based observational cohort study exploring pain and biomarkers in patients with hand osteoarthritis in Norway: The Nor-Hand protocol.

INTRODUCTION: We have limited knowledge about the underlying disease mechanisms and causes of pain in hand osteoarthritis (OA). Consequently, no disease-modifying drug exists, and more knowledge about the pathogenesis of hand OA is needed, as well as a validation of different outcome measures. Our first aim of this study is to explore the validity of various imaging modalities for the assessment of hand OA. Second, we want to gain a better understanding of the disease processes, with a special focus on pain mechanisms. METHODS AND ANALYSIS: The Nor-Hand study is a hospital-based observational study including 300 patients with evidence of hand OA by ultrasound and/or clinical examination. The baseline examination consists of functional tests and joint assessment of the hands, medical assessment, pain sensitisation tests, ultrasound (hands, acromioclavicular joint, hips, knees and feet), CT and MRI of the dominant hand, conventional radiographs of the hands and feet, fluorescence optical imaging of the hands, collection of blood and urine samples as well as self-reported demographic factors and OA-related questionnaires. Two follow-up examinations are planned. Cross-sectional analyses will be used to investigate agreements and associations between different relevant measures at the baseline examination, whereas the longitudinal data will be used for evaluation of predictors for clinical outcomes. ETHICS AND DISSEMINATION: The protocol is approved by the Norwegian Regional Committee for Medical and Health Research Ethics (Ref. no: 2014/2057). The participants receive oral and written information about the project and sign a consent form before participation. They can, whenever they want, withdraw from the study, and all de-identified data will be safely stored on the research server at Diakonhjemmet Hospital. Results will be presented at international and national congresses and in peer-reviewed rheumatology journals. TRIAL REGISTRATION NUMBER: NCT03083548; Pre-results.

Back to the Future - Part 2. Post-mortem assessment and evolutionary role of the bio-medicolegal sciences.

Part 2 of the review "Back to the Future" is dedicated to the evolutionary role of the bio-medicolegal sciences, reporting the historical profiles, the state of the art, and prospects for future development of the main related techniques and methods of the ancillary disciplines that have risen to the role of "autonomous" sciences, namely, Genetics and Genomics, Toxicology, Radiology, and Imaging, involved in historic synergy in the "post-mortem assessment," together with the mother discipline Legal Medicine, by way of its primary fundament, universally denominated as Forensic Pathology. The evolution of the scientific research and the increased accuracy of the various disciplines will be oriented towards the elaboration of an "algorithm," able to weigh the value of "evidence" placed at the disposal of the "justice system" as real truth and proof.
