Background Arterial spin labelling (ASL) is a noncontrast, magnetic resonance perfusion technique which can provide information about the parenchymal perfusion status and collaterals in acute stroke. Its role in the setting of large vessel occlusion (LVO) is underutilized due to the limited availability of magnetic resonance imaging (MRI) in the em...

Background: Imaging of acute stroke patients in emergency settings is critical for treatment decisions. Most commonly, CT with CTA is used worldwide for acute stroke. However, MRI may be advantageous in certain settings. With advancements in endovascular clot retrieval techniques, there is a need to identify and use the best possible imaging for th...

Recent studies have shown that diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) MRI (DWI-FLAIR) mismatch is useful for thrombolytic treatment decisions in acute ischemic stroke. However, the role of partial mismatch in strategic locations among patients with evolving stroke has not been described before. Partial imag...

Cardiac CT studies to detect embolic sources can be a useful supplement to the imaging armamentarium of acute stroke patients and we explore its possibilities in 2 distinct populations in this technical note. Prior literature has looked at the yield of covering the heart during CT angiography (CTA) in addition to echocardiography and found that it...

Craniofacial pain syndromes exhibit a high prevalence in the general population, with a subset of patients developing chronic pain that significantly impacts their quality of life and results in substantial disabilities. Anatomical and functional assessments of the greater occipital nerve (GON) have unveiled its implication in numerous craniofacial...

The majority of intracranial expansive lesions are tumors. However, a wide range of lesions can mimic neoplastic pathology. Differentiating pseudotumoral lesions from brain tumors is crucial to patient management. This article describes the most common intracranial pseudotumors, with a focus on the imaging features that serve as clues to detect pse...

Neonatal strokes constitute a major cause of pediatric mortality and morbidity. Neuroimaging helps in its diagnosis as well as prognostication. However, advanced imaging, including magnetic resonance imaging (MRI), carries multiple challenges. Limited data exists in the literature on imaging-based predictors of neurological outcomes in neonatal str...

A brief overview of our epilepsy protocol and review its sequences The spectrum of imaging findings in our acute seizure patients Differentiation of seizure-induced changes on imaging from underlying causes Diagnostic algorithm for seizure imaging using case-based examples

Aim The aim of this article was to assess the profile of T2-weighted (T2W) multipoint Dixon sequence and conventional sequences in magnetic resonance imaging (MRI) of sacroiliac joints for the diagnosis of active and chronic sacroiliitis. Settings and Design Prospective observational study. Materials and Methods Thirty-seven patients with sacroilii...

Purpose To probe the pathophysiological basis of Modic change (MC) by multimodal imaging rather than by MRI alone. Methods Nineteen radiological signs found in mild infections and traumatic endplate fractures were identified by MRI and CT, and by elimination, three signs unique to infection and trauma were distilled. By ranking the Z score, radiol...

Postoperative imaging following orthopaedic surgeries is essential in assessing complications post-surgery and also helps plan further treatment. Combining a high degree of clinical insight with appropriate imaging can guide the treating clinician to the correct diagnosis. Imaging is quite challenging because of surgery-related soft tissue changes,...

The COVID-19 pandemic had brought unique and difficulties challenges to emergency health care services worldwide. Indian scenario was no different and public fear of the pandemic combined with strict travel restrictions enforced during the initial lockdown phases drastically affected number of patients seeking emergency medical attention. Stroke i...

Acute Stroke is managed by a multidisciplinary team and treatment decisions are based on imaging studies. The goals of imaging for various treatments in acute stroke are outlined and incorporated into an imaging-based flow chart.We have developed simplified and structured reporting formats to avoid confusion and treatment delays as well as for medi...

Conventional techniques of vascular imaging (CTA, MRA and DSA) reveal abnormalities of the lumen of the vessel. However, most vascular pathologies show similar lumenographic findings. Intracranial high resolution vessel wall imaging (vWI) has emerged as a promising tool which can directly visualize and characterize the disease of the vessel wall. W...
