Diagnostic Accuracy of Hyperdense Artery Sign in Early Detection of Middle Cerebral Artery Infarction: A Cross-Sectional Validation Study.
Ann Neurosci
October 2024
Department of Radiology, Aga Khan University Hospital, Stadium Road, Karachi, Pakistan.
Background: Hyperdense middle cerebral artery sign (HMCAS) on a non-enhanced multidetector computed tomography (MDCT) scan is considered an important radiological marker in detecting acute arterial thrombotic occlusion, and it is one of the earliest signs of ischemic cerebrovascular accident (CVA). This finding has been observed within 90 min of symptom onset. Modern approaches to patients with cerebral infarction emphasize early diagnosis and management.

Upper tract urothelial carcinoma (UTUC) is a rare and challenging subset of the more frequently encountered urothelial carcinomas (UCs), comprising roughly 5-7% of all UCs and less than 10% of all renal tumors. Hematuria is a common presenting symptom in the emergency setting, often prompting imaging to rule out serious etiologies, with UTUC especially posing as a diagnostic challenge. These UTUC lesions of the kidney and ureter are often small, mimicking other pathologies, and are more aggressive than typical UC of the bladder, emphasizing the importance of timely and accurate diagnosis.

Department of Cardiology, Keio University School of Medicine, Tokyo, Japan.
Background: The short-term and midterm impact of gender differences on transcatheter aortic valve implantation (TAVI) has been studied. However, the impact on long-term clinical outcomes remains unclear. The objective of the study was to investigate the impact of gender differences after TAVI on long-term clinical outcomes and structural valve deterioration (SVD).

National Manager-Health System Strengthening, United Nations Development Program (UNDP), 55 Lodhi Estate, New Delhi, India.
Background: The purpose of this paper is to compare the efficacy of dual-phase multidetector computed tomography angiography (CTA) with transthoracic echocardiogram (TTE) and cardiac catheterization angiography (CCA) in evaluation of pulmonary arteries and collateral vessels, major aortopulmonary collateral arteries (MAPCAs) in children with cyanotic congenital heart diseases.
Methods: The study was a prospective observational study where 32 pediatric patients (18 males, 14 females and age range 2-116 months) with cyanotic congenital heart diseases (CCHD) were included. All patients underwent TTE, CTA, and CCA.
