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...

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...

Objective To evaluate the accuracy of noninvasive imaging methods including gray-scale ultrasound, ultrasound shear wave elastography, unenhanced computed tomography (CT), and proton density fat fraction (PDFF) on magnetic resonance imaging (MRI) using three-dimensional (3D) multiecho multipoint chemical shift–encoded spoiled gradient echo (q-DIXON...

Objectives Our objective was to analyze the clinical presentation, imaging findings, and the management of segmental arterial mediolysis (SAM) in different case scenarios within our medical institution. Materials and Methods We retrospectively analyzed 13 cases of SAM in our institution from July 2017 to March 2020. The images from the cases were c...

May-Thurner syndrome (MTS) is a venous compression syndrome in which the left common iliac vein (LCIV) is compressed between the lower lumbar spine and the right common iliac artery (RCIA). Variations are known where in the right lower limb can be affected. While most of the cases are asymptomatic, it can cause severe morbidity in symptomatic indiv...
Article
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...
Article
Thoracic aortic injuries caused by high impact trauma are life-threatening and require emergent diagnosis and management. With improvement in the acute care services, an increasing number of such injuries are being managed such that patients survive to undergo definitive therapies. A high index of clinical suspicion is required to order appropriate...

Trigeminal neuralgia (TGN) is often caused by a neurovascular conflict at the root entry zone of the fifth nerve. Dural arteriovenous fistula (DAVF) accounts for 3%-4% cases of TGN. We report a posttraumatic head injury patient, presenting with gait ataxia and right facial pain. Radiographic evidence with magnetic resonance imaging and digital subt...
Chapter
Liver can commonly get injured in blunt abdominal injury or secondary to penetrating injury. Often mortality is related to the delay in hemostasis. The combination of CT scanning to locate the site of bleed followed by embolization can be a lifesaving procedure in both the hemodynamically stable as well as unstable patients. Spleen, on the other ha...
Article
Background We review our initial experience of India’s and Asia’s first mobile stroke unit (MSU) following the completion of its first year of operation. We outline the clinical care pathway integrating the MSU services using a case example taking readers along our clinical care workflow while highlighting the challenges faced in organizing and opt...

CT angiogram (CTA) has become the modality of choice for imaging of thoracic vascular pathologies, involving the aorta and the pulmonary arteries. Apart from showing exquisite details of these large arteries, pathologies and anatomic variants of their branches can also be studied to a great extent. The major branches of aortic arch can be affected...

Coronary arteriovenous (AV) fistulae are rare congenital anomalies and encompass a wide variety of communications between the coronary artery and the pulmonary or systemic vasculature. Symptoms depend on the presence and severity of myocardial malperfusion secondary to coronary artery steal phenomenon at rest or exertion. These fistulae are traditi...

Intracranial interventions comprise a set of procedures, which are complex and challenging. Further, they are extremely risky because complications in the brain are usually associated with significant mortality and morbidity. Thus, a clear understanding is necessary to handle tortuous vessels because improper planning can result in a higher rate of...

Introduction A pneumatized turbinate, also called concha bullosa, is a normal anatomical variant of the paranasal sinus region. Depending on the site of pneumatization, the concha is classified into extensive, bulbous or lamellar type. The middle turbinate concha bullosa has been implicated as a possible etiological factor in chronic sinusitis. Obj...

Presence of ischemic penumbra is the principal factor that decides the need for mechanical thrombectomy in acute stroke patients with large vessel occlusion. Our objective was to evaluate the usefulness of arterial spin labeling (ASL) in detecting diffusion perfusion mismatch and directing patients into mechanical thrombectomy. We retrospectively s...

Blood blister aneurysms are extremely rare, and its treatment continues to be controversial. Although surgery was the only available treatment a decade ago, today newer endovascular devices such as flow diverters (FDs) appears to have very low complication rates with good long-term results. We analyzed our data of seven patients who angiographicall...

Purpose Acute ischemic stroke was not long ago the territory of the neurologist, where the endovascular surgeon had only started baby steps. The scenario has completely changed post-2015 and now mechanical thrombectomy holds centerstage of the treatment guidelines. The two basic techniques for clot retrieval are the stent retriever thrombectomy and...

Background & objectives: Renal size is an important parameter used in the diagnosis and follow up of renal diseases. However, while making decisions, clinicians must be aware of the dependence of these dimensions on the ethnicity of the individual, independent of anthropometric indices. There is no established nomogram for renal sizes in the Indian...
