Breast arterial calcification detection using AI was assessed in 253 patients who underwent 314 digital mammography (DM) examinations and 143 patients who underwent 277 digital breast tomosynthesis (DBT) examinations between October 2004 and September 2022.

Phenotypic, Electrophysiologic, and Imaging Spectrum of Hirayama Disease from Northern India.

Background And Objectives: Cervical flexion-induced myelopathy, also known as Hirayama disease (HD), is a lower motor neuron disorder seen mainly in adolescents and young adults, affecting the C7-T1 myotomes, presenting as asymmetric weakness with wasting of one or both the distal upper limbs. We aimed to describe the clinical features, electrophysiology, and radiologic features of HD in a tertiary care institute in northern India.

Methods: One hundred and forty patients between 2017 and 2022 with clinical and imaging features consistent with HD were retrospectively reviewed from the All India Institute of Medical Sciences-Comprehensive Neuromuscular Diseases center database.

Imaging and MR Spectroscopy in Papillary Craniopharyngioma.

Sellar-suprasellar masses exhibit a diverse range of differential diagnoses and it is feasible to establish a preliminary diagnosis before surgery by evaluating conventional CT scans and contrast-enhanced MRI results. Nevertheless, certain cases may present with inconclusive findings, making it challenging to anticipate the underlying tissue composition accurately through imaging alone. Researchers have explored the application of Proton MR spectroscopy in analyzing suprasellar tumors, and their investigations have revealed that it can complement traditional MRI by enhancing the accuracy of preoperative diagnoses.

Spectrum of various CNS inflammatory demyelination diseases following COVID-19 vaccinations.

Background And Purpose: Although rare, neurological adverse events have been reported post-COVID-19 vaccination. This study reports 16 patients diagnosed with CNS inflammatory demyelinating diseases (CNS-IDD) within 6 weeks of COVID-19 vaccine administration.

Methodology: A prospective observational study was conducted from June 2021 to May 2022.

Inter-software and inter-scan variability in measurement of epicardial adipose tissue: a three-way comparison of a research-specific, a freeware and a coronary application software platform.

Objectives: Epicardial adipose tissue (EAT) is a proposed marker of cardiovascular risk; however, clinical application may be limited by variability in post-processing software platforms. We assessed inter-vendor agreement of EAT volume (EATv) and attenuation on both contrast-enhanced (CE) and non-contrast CT (NCT) using a standard coronary CT reporting software (Vitrea), an EAT research-specific software (QFAT) and a freeware imaging software (OsiriX).

Methods: Seventy-six consecutive patients undergoing simultaneous CE and NCT had complete volumetric EAT measurement.

Ureterorenoscopic stone procedures have low success rates and poor post-operative follow-up: results from an Australian tertiary health service.

Background: To assess the results of ureterorenoscopy (URS) for upper tract urolithiasis in a contemporary Australian tertiary healthcare setting.

Methods: Hospital records of all URS stone procedures performed between January 2017 and December 2018 in a metropolitan service were retrospectively reviewed. Outcome measures including stone free rates, adherence to postoperative follow-up and complications rates were recorded.

Clinical and radiological spectrum of anti-myelin oligodendrocyte glycoprotein (MOG) antibody encephalitis: single-center observational study.

Objective: The objective was to describe the clinical presentations, radiologic features, and outcomes of patients with autoimmune encephalitis associated with myelin oligodendrocyte glycoprotein antibody (MOG).

Background: During the past decade, the spectrum of the myelin oligodendrocyte glycoprotein antibody-associated diseases (MOGAD) has expanded. Recently, patients with MOG antibody encephalitis (MOG-E) who do not fulfill the criteria for ADEM have been reported.

Giant dissecting aneurysm of basilar artery in a child - treated by flow reversal: A case report.

Although intracranial aneurysms are rare in the paediatric population, the proportion of those involving posterior circulation is higher than that of adults (approximately 25% vs. 8%, respectively). Moreover, posterior circulation aneurysms in kids tend to be larger in size, many of them being giant dissecting types, and treatment of them is often challenging.

"Ear of the Lynx" Sign in Hereditary Spastic Paraparesis (HSP) 76.

Background: Hereditary Spastic Paraparesis HSP) are a group of genetically inherited disorders, clinically and genetically heterogenous and characterized by degeneration of corticospinal tracts, manifesting with progressive spasticity and lower limbs weakness. Most HSPs have an autosomal dominant inheritance. "Ear of the Lynx" sign describes the characteristic abnormality in the forceps minor region of the corpus callosum (CC) on MRI brain.

A Novel Co-existence of Spinocerebellar Ataxia 1 and Spinocerebellar Ataxia 2 Mutations in Indian Patients.

Background: Spinocerebellar ataxia 1 (SCA1) and SCA2 are dominantly inherited ataxias caused due to CAG expansion mutation in (CAG≥39) and (CAG≥32) genes located at 6p22.3 and 12q24.12 loci, respectively, with key manifestations of progressive limb and gait ataxia and with or without brain stem and pyramidal tract involvement.

Breast arterial calcification and epicardial adipose tissue volume, but not density are independently associated with cardiovascular risk.

Background: Mammographically detected breast arterial calcification (BAC) has been proposed as surrogate marker for coronary artery disease (CAD) in women. Epicardial adipose tissue (EAT) and peri-coronary adipose tissue (PCAT) are inflammatory fat depots linked to atherogenesis. BAC has demonstrated association with inflammation, therefore we aimed to determine the association between BAC, EAT and PCAT.

Disseminated Cysticercosis-Should we treat?

Disseminated cysticercosis is defined by the presence of multiple vesicular cystic lesions in the brain with cysts demonstrable in at least two other body parts. The exact course of disseminated cysticercosis is not known and the individual cysts either become inflamed or calcify. A patient's quality of life is often poor and disseminated cysticercosis treatment is far from satisfactory.

Cost of HSCT in a Tertiary Care Public Sector Hospital in India.

India harbours a significant burden of hematological diseases including cancers for which Hematopoietic Cell Transplant (HCT) is a definitive life-saving procedure. Very few studies in India have carried out the costing of the important procedure, hence we undertook a study to ascertain the cost of auto HCT in our tertiary care teaching hospital. We did a prospective study using Top-down and Bottom-up approach to arrive at the cost of autologous HCT which came out to be INR 699,200 ($10,282) out of which hospital bears 34% of the cost.

COVID-19: Indian Society of Neuroradiology (ISNR) Consensus Statement and Recommendations for Safe Practice of Neuroimaging and Neurointerventions.

The ongoing COVID-19 pandemic has forced every radiology set-up to evolve and formulate guidelines for day-to-day functioning. The sub-speciality of neuroradiology, both diagnostic and neuro-intervention, forms a very important part of any radiology or 'neuro-care' set-up. The present document is a consensus statement of the Indian Society of Neuroradiology, prepared after reviewing the available data and working experience.

Impaired conflict monitoring in Parkinson's disease patients during an oculomotor redirect task.

Fallibility is inherent in human cognition and so a system that will monitor performance is indispensable. While behavioral evidence for such a system derives from the finding that subjects slow down after trials that are likely to produce errors, the neural and behavioral characterization that enables such control is incomplete. Here, we report a specific role for dopamine/basal ganglia in response conflict by accessing deficits in performance monitoring in patients with Parkinson's disease.

Fungal granuloma of the brain caused by Cladosporium bantianum--a case report and review of literature.

Involvement of the brain by neurotropic, dematiaceous fungi namely Cladosporium bantianum is extremely rare. The disease is very resistant to treatment and prone for frequent relapses despite treatment with amphotericin B and flucytosine, the drugs of choice for the infection. Surgery is often required for resection of the fungal granuloma.
